The emission benefits of shifting towards battery electric vehicles have so far been hampered by a trend towards sports utility vehicles (SUVs). This study assesses the current and future emissions from SUVs and their potential impact on public health and climate targets. We modelled five scenarios of varying SUV sales and electrification rates, and projected associated carbon dioxide (CO₂) and nitrogen oxide (NO_x) emissions. Multiple linear regression was used to determine the relationship between vehicle characteristics and emissions. Cumulative CO₂ emissions were valued using the social cost of carbon approach. Life table analyses were used to project and value life years saved from NO_x emission reductions. Larger SUVs were disproportionately high emitters of CO₂ and NO_x. Replacing these with small SUVs achieved significant benefits, saving 702 MtCO₂e by 2050 and 1.8 million life years from NO₂ reductions. The largest benefits were achieved when combined with electrification, saving 1181 MtCO₂e and gaining 3.7 million life years, with a societal value in the range of GBP 10–100s billion(s). Downsizing SUVs could be associated with major public health benefits from reduced CO₂ and NO_x emissions, in addition to the benefits of electrification. This could be achieved by demand-side mass-based vehicle taxation and supply-side changes to regulations, by tying emission limits to a vehicle’s footprint rather than its mass. Full article

Background: The use of a decision aid for choosing whether to have or not have anesthesia during childbirth has been shown to increase both knowledge about birth and the proportion of women who made their own decisions compared with women who did not use a decision aid. Herein, we updated the first version of our decision aid into a second version and evaluated this updated decision aid. We evaluated the face validity and content appropriateness of the updated decision aid developed to enhance the ability of women to choose between childbirth with or without epidural analgesia. Methods: This was a descriptive study based on a literature review of updated information for addition to the first version. PubMed and Cochrane Library were searched from 2003 to May 2021. Thereafter, obstetricians, anesthesiologists, and midwives were asked to respond to a questionnaire regarding the face validity and content appropriateness of the updated decision aid regarding whether it meets the IPDASi (Version 4.0) quality standards. Results: One obstetrician, one anesthesiologist, and three midwives who had performed epidural anesthesia for at least three years responded to the questionnaire. The responses to the evaluation items of face validity (i.e., style and clarity) were positive. There were 38 specific comments regarding content appropriateness classified into seven categories: “addition or revision of text”, “unification of expressions”, “need for explanation/information”, “lack of evidence”, “potential to mislead”, “questionable”, and “structure”. Conclusion: The face validity and content appropriateness of the updated decision aid was confirmed. The next step is evaluation of the updated decision aid by pregnant women who give birth.

The COVID-19 pandemic led many countries to apply lockdown measures that could prevent children from achieving the physical activity, sedentary behavior, and sleep levels suggested for their psychophysical health. The current study tested changes in physical activity, sedentary behavior, and sleep length of children and the incidence of achieving the 24 h movement standards through the limitations of COVID-19. A total of 490 Arab Israeli parents were surveyed. An electronic cross-sectional survey was performed, including questions addressing engagement in physical activities, use of screens, and sleep duration. Throughout the COVID-19 outbreak, time spent participating in physical activity was reduced, sedentary behavior and sleep duration were increased, and the percentage of the sample who met the physical activity and sedentary behavior suggestions lessened. The percentage of participants who attained the overall 24 h movement recommendations was very low during the pandemic; school children met the guideline recommendations for physical activity and sleep duration more than preschool children, and girls spent more time in physical activity. These findings highlight the need for strategies to enhance physical activity and decrease sedentary behavior in children to prevent long-term effects of limitations imposed by COVID-19. Efforts to perceive and encourage healthy routines in Arab Israeli children in the case of pandemic limitations are expected to serve as a precedence. Full article

(1) Background: This prospective study aimed to identify predictors of falls and fall-related fractures in community-dwelling older people with pain; (2) Methods: Participants comprised 389 community-dwelling older people aged 70+ years who had musculoskeletal pain in the neck, back, hip, leg/knee and/or feet. Demographic, anthropometric, balance, mobility, cognitive function, psychological status and physical activity level measures were obtained at baseline. Falls were monitored with monthly falls calendars for 12 months. Logistic regression analyses were performed to identify predictors of falls and fall-related fractures during a 12-month follow-up; (3) Results: Of the 389 participants, 175 (45.0%) and 20 (5.1%) reported falls and fall-related fractures during the 12-month follow-up, respectively. Greater postural sway on foam, more depressive symptoms and lower physical activity levels at baseline were associated with falls during the 12-month follow-up. Slower walking speed at baseline was associated with fall-related fractures during the 12-month follow-up. These associations remained significant after adjusting for age, sex, body mass index, comorbidities and medication use; (4) Conclusions: This study suggests poor balance, low mood and a less active lifestyle are predictors of falls, and slower walking speed predicts fall-related fractures among community-dwelling older people with pain.

Background. Disability (both temporary and transitory, or definitive) might occur for the first time in a given patient after an acute clinical event. It is essential, whenever indicated, to undergo a Physical Medicine and Rehabilitation assessment to detect disability and any need for rehabilitation early. Although access to rehabilitation services varies from country to country, it should always be governed by a PRM prescription. Objective. The aim of the present observational retrospective study is to describe consultancy activity performed by PRM specialists in a university hospital in terms of requests’ typology, clinical questions, and rehabilitation setting assignment. Methods. Multiple parameters were analyzed (clinical condition, patient’s socio-family background, and rehabilitation assessment scale scores) and a correlation analysis was performed between the analyzed characteristics and both the different clinical conditions and the assigned rehabilitation setting. Results. PRM evaluations of 583 patients from 1 May 2021 to 30 June 2022 were examined. Almost half of the total sample (47%) presented disability due to musculoskeletal conditions with a mean age of 76 years. The most frequently prescribed settings were home rehabilitation care, followed by intensive rehabilitation and long-term care rehabilitation. Conclusions. Our results suggest the high public health impact of musculoskeletal disorders, followed by neurological disorders. This is, however, without forgetting the importance of early rehabilitation to prevent other types of clinical conditions such as cardiovascular, respiratory, or internal diseases from leading to motor disability and increasing costs.

Clinical education is a mandatory component of physical therapy curricula globally. COVID-19 disrupted clinical education, jeopardizing students’ abilities to meet graduation requirements. The objective of this case report is to outline the development, implementation and evaluation of a multiple clinical instructor (CI), multiple unit, acute care float clinical placement for a final year, entry-level physical therapy student and offer implementation recommendations. This placement included an eight-week, multiple CI (one primary, four supporting), multiple (five) unit clinical placement which was developed between St. Joseph’s Healthcare and the McMaster University Masters of Science (Physiotherapy) Program between 10 August and 2 October 2020. Student evaluations and reflections by the student and CIs were collected and analyzed using interpretive description. Analysis from the reflections revealed six themes: (1) CI and student attributes; (2) increased feasibility; (3) varied exposure; (4) central communication and resources; (5) organization; and (6) managing expectations. An acute care clinical experience is required for students in Canadian entry-to-practice physical therapy programs. Due to COVID-19, placement opportunities were limited. The float placement allowed clinicians to offer supervision despite staff re-deployment and increased organizational and work–life pressures during the pandemic. This model provides an approach to extenuating circumstances and may also increase acute care placements during non-pandemic times for physical therapy and other similarly structured healthcare professions.

Background: Nurses are exposed to potentially psychologically traumatic events which can lead to operational stress injuries (OSI). Workplace reintegration after an OSI can be challenging, especially with repeated exposure to potentially traumatic scenarios and workplace demands. A workplace reintegration program (RP) originally developed for police officers may be of benefit for nurses returning to work after an OSI. The purpose of this study is to investigate the perceived need for an RP for nurses, and its potential contextualization and implementation in the nursing context using an implementation science approach. Methods: This mixed-methods study collected data via questionnaires and focus groups from acute care nurses in Canada (N = 19). Data analysis was conducted using descriptive statistics, thematic analysis, and an organizational readiness assessment. Results: Study participants indicated that formalized processes were rarely used to support nurses returning to work after time off due to mental health challenges. Themes included (1) “The Perfect Storm”: the current state of return-to-work, (2) Integral Needs, and (3) A Break in the Clouds: hope for health. Conclusions: Exploration of innovative programs such as the RP may provide additional support to nurses affected by OSIs. Further research is needed regarding workplace reintegration for nurses, and contextualization and evaluation of the RP. Full article

Not much is known about how the COVID-19 pandemic affected the labor market experiences of people with disabilities. Since they constitute a generally disadvantaged group in the labor market, it is important to scrutinize whether their position has worsened during these difficult times and how they reacted with regard to their job search behavior. We therefore used data for the year 2020 from a large German panel (Panel Arbeitsmarkt und Soziale Sicherung, PASS), in order to scrutinize the prevalence of unemployment among people with disabilities (N = 739) during the first year of the COVID-19 pandemic. The factors that affected their unemployment status were also analyzed. The study found that people with legally recognized disabilities were more often unemployed than non-disabled people, even when controlling for possible confounding factors such as age, gender, or education. This effect was significant for severe disabilities and marginally significant for minor disabilities. Additionally, the type of disability affected the probability of being unemployed, with cardiovascular diseases, mental illnesses, and musculoskeletal disorders carrying a higher risk. In terms of job-seeking behavior, unemployed people with disabilities reported using some job search methods more frequently than their non-disabled counterparts. However, the intensity of the job search did not differ significantly between the two groups. Further differences were found when analyzing the reasons for abstinence from searching for a job, with unemployed people with disabilities primarily citing health-related factors (with a frequency of over 90%). In summary, health played a pivotal role in determining disabled people’s labor market experiences during the COVID-19 pandemic. Full article

This randomized controlled trial examined the impact of a psychoeducational group program on the mental well-being of unit-based nurse leaders, specifically nurse managers and assistant nurse managers. The program was developed around the themes of resilience, insight, self-compassion, and empowerment to fight burnout and enhance purposeful adaptive coping to reduce distress and improve mental wellbeing. The sample included 77 unit-based nurse leaders. Outcomes included post-traumatic growth, resilience, insight, self-compassion, empowerment, perceived stress, burnout, and job satisfaction. Paired samples t-tests and repeated measures ANOVA tests were conducted to compare outcomes at baseline to the follow-up timepoints of endpoint, one-month follow-up, three-month follow-up, and six-month follow-up. The intervention group participants showed significant improvement in post-traumatic growth between baseline and all follow-up timepoints compared to the waitlist control group. Among intervention group participants, there were also significant improvements in self-reflection and insight, self-compassion, psychological empowerment, and compassion satisfaction, as well as significant reductions in perceived stress, burnout, and secondary traumatic stress. This study extends existing evidence that this psychoeducational group program can be an effective intervention for improving and protecting mental wellbeing. Among nurse leaders, it can reduce stress and burnout and improve post-traumatic growth, self-reflection and insight, self-compassion, psychological empowerment, and compassion satisfaction.

Background: Psychiatric medications play a vital role in the management of mental health disorders. However, the COVID-19 pandemic and subsequent lockdown limited access to primary care services, leading to an increase in remote assessment and treatment options to maintain social distancing. This study aimed to investigate the impact of the COVID-19 pandemic lockdown on the use of psychiatric medication in primary care settings. Methods: We conducted a retrospective claims-based analysis of anonymized monthly aggregate practice-level data on anxiolytics and hypnotics use from 322 general practitioner (GP) practices in the North East of England, where health disparities are known to be higher. Participants were all residents who took anxiolytics and hypnotics from primary care facilities for two financial years, from 2019/20 to 2020/21. The primary outcome was the volume of Anxiolytics and Hypnotics used as the standardized, average daily quantities (ADQs) per 1000 patients. Based on the OpenPrescribing database, a random-effect model was applied to quantify the change in the level and trend of anxiolytics and hypnotics use after the UK national lockdown in March 2020. Practice characteristics extracted from the Fingertips data were assessed for their association with a reduction in medication use following the lockdown. Results: This study in the North East of England found that GP practices in higher health disparate regions had a lower workload than those in less health disparate areas, potentially due to disparities in healthcare utilization and socioeconomic status. Patients in the region reported higher levels of satisfaction with healthcare services compared to the England average, but there were differences between patients living in higher versus less health disparate areas. The study highlights the need for targeted interventions to address health disparities, particularly in higher health disparate areas. The study also found that psychiatric medication use was significantly more common in residents living in higher health disparate areas. Daily anxiolytics and hypnotics use decreased by 14 items per 1000 patients between the financial years 2019/20 and 2020/21. A further nine items per 1000 decreased for higher health disparate areas during the UK national lockdown. Conclusions: People during the COVID-19 lockdown were associated with an increased risk of unmet psychiatric medication demand, especially for higher health disparate areas that had low-socioeconomic status.

Whilst recognising and advocating for the role and importance of schools and whole school approaches to the promotion of physical activity in schools, this paper argues that physical education (PE) should be at the centre of and driving schools’ efforts to promote physical activity. Various reasons are given for this, with these broadly centring on the unique goal, nature, and responsibilities of the subject with respect to promoting physically active lifestyles and health-related learning. Furthermore, there have been positive strides in recent years to support this endeavour and that serve to highlight, strengthen, and reinforce the focus and responsibility of PE in the promotion of physical activity. In light of these, it is suggested that it is a pivotal time for PE. Equally, it is accepted that PE faces some longstanding challenges that are hindering and raise questions concerning the subject’s physical activity promotion efforts. Despite this, it is contended that these should not be unsurmountable, and more recent developments should also help the subject to realise its physical activity promoting potential moving forwards. In particular, the critical importance of high-quality PE that has young people at the core is highlighted. It is concluded that it is both time and timely for the PE profession to be bold, have confidence, and grasp these opportunities and ensure that high-quality PE is central to the explicit planning and co-ordination of meaningful, coherent, relevant, and sustainable physical activity opportunities for young people in schools.

Information about suicidal behavior in Nepal is limited. According to official records, suicide rates were high until the year 2000 and declined thereafter. Official records are considered unreliable and a gross undercounting of suicide cases, particularly female cases. Suicide research in Nepal has been mostly epidemiologic and hospital-based. Little is known about how suicide is understood by Nepali people in general—including dominant suicide attitudes and beliefs in Nepal. Suicide attitudes and beliefs, which are elements of a culture’s suicide scripts, predict actual suicidality. Drawing on suicide-script theory, we developed and used a semi-structured survey to explore Nepali beliefs about female and male suicide. The informants were adult (M_age = 28.4) university students (59% male). Female suicide was believed to be a response to the society-sanctioned oppression and abuse that women are subjected to, in their family and community. The prevention of female suicide was viewed as requiring dismantling ideologies, institutions, and customs (e.g., child marriage, dowry) that are oppressive to women, and ensuring that women are protected from violence and have equal social and economic rights and opportunities. Male suicide was believed to be a symptom of societal problems (e.g., unemployment) and of men’s psychological problems (e.g., their difficulties in managing emotions). The prevention of male suicide was viewed as requiring both societal (e.g., employment opportunities) and individual remedies (e.g., psychological counseling). This study’s findings suggest that a semi-structured survey can be a fruitful method to access the suicide scripts of cultures about which there is limited research. Full article

Studies have linked HIV-risky behaviours among young people to several socio-contextual factors. However, the social factors that might increase African Canadian adolescents’ exposure to HIV-risky behaviours, including unprotected sex and forced or multiple-sexual partnerships, have received little or no attention in the literature. Using data from the British Columbia Adolescent Health Surveys (2003–2018) and guided by intersectionality and socio-ecological frameworks, we examined the social determinants of HIV-risky behaviours (HRB) among African Canadian adolescents in British Columbia. We observed a general decline in HRB from 2008 to 2018. However, more than half (54.5%) of the 1042 who were sexually experienced in 2018 reported having 2 or more sexual partners, and nearly half reported condom-less sex. Our results demonstrate an important need to evaluate the impacts of several social factors on health outcomes for a unique, marginalized population. Full article

H5Nx highly pathogenic avian influenza (HPAI) viruses of clade 2.3.4.4 have caused outbreaks in Europe among wild and domestic birds since 2016 and were introduced to North America via wild migratory birds in December 2021. We examined the spatiotemporal extent of HPAI viruses across continents and characterized ecological and environmental predictors of virus spread between geographic regions by constructing a Bayesian phylodynamic generalized linear model (phylodynamic-GLM). The findings demonstrate localized epidemics of H5Nx throughout Europe in the first several years of the epizootic, followed by a singular branching point where H5N1 viruses were introduced to North America, likely via stopover locations throughout the North Atlantic. Once in the United States (US), H5Nx viruses spread at a greater rate between US-based regions as compared to prior spread in Europe. We established that geographic proximity is a predictor of virus spread between regions, implying that intercontinental transport across the Atlantic Ocean is relatively rare. An increase in mean ambient temperature over time was predictive of reduced H5Nx virus spread, which may reflect the effect of climate change on declines in host species abundance, decreased persistence of the virus in the environment, or changes in migratory patterns due to ecological alterations. Our data provide new knowledge about the spread and directionality of H5Nx virus dispersal in Europe and the US during an actively evolving intercontinental outbreak, including predictors of virus movement between regions, which will contribute to surveillance and mitigation strategies as the outbreak unfolds, and in future instances of uncontained avian spread of HPAI viruses.

The health crisis has had a strong impact on intensive care units. The objective of this study was to investigate the experience of resuscitation physicians during the COVID-19 health crisis to understand the associated determinants of quality of life, burnout, and brownout. This qualitative, longitudinal study covered two periods (T1, February 2021, and T2, May 2021). The data were collected in individual semi-directed interviews with 17 intensive care physicians (ICPs) (T1). Nine of the latter also participated in a second interview (T2). The data were examined using grounded theory analysis. We identified a multiplication of burnout and brownout indicators and factors already known in intensive care. In addition, burnout and brownout indicators and factors specific to the COVID-19 crisis were added. The evolution of professional practices has disrupted the professional identity, the meaning of work, and the boundaries between private and professional life, leading to a brownout and blur-out syndrome. The added value of our study lies in identifying the positive effects of the crisis in the professional domain. Our study revealed indicators and factors of burnout and brownout associated with the crisis among ICPs. Finally, it highlights the beneficial effects of the COVID-19 crisis on work. Full article

Background: Unemployment is known to have negative effects on mental and physical health. Yet, the effectiveness of interventions aimed at improving the health of unemployed people is unclear. Methods: We conducted a random-effects meta-analysis of extant intervention studies with at least two measurement points and a control group. A literature search in PubMed, Scopus, and PsycINFO in December 2021 identified 34 eligible primary studies with 36 independent samples. Results: For mental health, the average meta-analytic effect sizes for the comparison of the intervention group and the control group were significant and of small size after the intervention, d = 0.22; 95% CI [0.08, 0.36], as well as at follow-up, d = 0.11; 95% CI [0.07, 0.16]. Effects on self-assessed physical health status were small and marginally significant (p = 0.10) after the intervention: d = 0.09; 95% CI [−0.02, 0.20], and insignificant at follow-up. However, when job search training was not part of the intervention program (i.e., all available resources were used solely for health promotion), the average effect size for physical health was significant after the intervention, d = 0.17; 95% CI [0.07, 0.27]. Furthermore, the effects of physical activity promotion were significant and of small-to-medium size after the intervention, leading to increased levels of activity, d = 0.30; 95% CI [0.13, 0.47]. Conclusions: Population-based health promotion programs are recommended because even measures with small effect sizes can actually improve the health of a large group of unemployed people.

Physical activity guidelines for health recommend any type of unstructured physical activity for health promotion. Adults should perform at least 150–300 min per week of moderate intensity or 75–150 min per week of vigorous intensity activities, or an equivalent combination of the two intensities. However, the relationship between physical activity intensity and longevity remains a debated topic, with conflicting perspectives offered by epidemiologists, clinical exercise physiologists or anthropologists. This paper addresses the current known role of physical activity intensity (in particular vigorous versus moderate intensity) on mortality and the existing problems of measurement. Given the diversity of existing proposals to categorize physical activity intensity, we call for a common methodology. Device-based physical activity measurements (e.g., wrist accelerometers) have been proposed as a valid method to measure physical activity intensity. An appraisal of the results reported in the literature, however, highlights that wrist accelerometers have not yet demonstrated sufficient criterion validity when they are compared to indirect calorimetry. Novel biosensors and wrist accelerometers will help us understand how different metrics of physical activity relates to human health, however, all these technologies are not enough mature to provide personalized applications for healthcare or sports performance.

We hypothesize that the control of tongue position using a newly developed tongue position retainer, where the tongue is held in a protruded position (i.e., intervention A) or in its resting position (i.e., intervention B), is effective for maintaining upper airway patency in obstructive sleep apnea (OSA) compared with no control of tongue position. This is a randomized, controlled, non-blinded, crossover, and two-armed trial (i.e., sequence AB/BA) in 26 male participants (i.e., sample size) who are scheduled to undergo a dental operation under intravenous sedation with OSA (10 ≤ respiratory event index < 30/h). Participants will be randomly allocated into either sequence by a permuted block method, stratified by body mass index. Under intravenous sedation, participants will undergo two interventions, separated by a washout period after receiving intervention A or intervention B using a tongue position retainer after baseline evaluation, before each intervention is provided. The primary outcome is the abnormal breathing index of apnea as determined by the frequency of apnea per hour. We expect that, compared with no control of tongue position, both intervention A and intervention B will improve the abnormal breathing events with superior effects achieved by the former, offering a therapeutic option for OSA.

Antibiotics have undoubtedly revolutionized medicine and the health and survival of patients with life-threatening infections, being nonetheless free from potential adverse effects, and the risk of intestinal dysbiosis, antimicrobial resistance, and the resulting consequences for the patient’s health and the public purse. The present study narratively reviewed the epidemiological data on worldwide antibiotic consumption and administration in dental practice, patients’ adherence to prescriptions, the antimicrobial resistance phenomenon in dentistry, and the evidence supporting and recommending appropriate antibiotic use in dental care. Eligible systematic reviews and original studies in humans published in the English language from January 2000 to 26 January 2023 were considered. A total of 78 studies, 47 on the epidemiology of antibiotic use and prescription in dentistry, 6 on antibiotic therapy in dentistry, 12 on antibiotic prophylaxis in dentistry, 0 on adherence of dental patients to antibiotic prescription, and 13 on antimicrobial resistance in dentistry, were presently considered. Retrieved evidence revealed that antibiotics are frequently overused and misused in dental practice, dental patients frequently do not adhere to prescriptions, and antimicrobial resistance in dentistry is a still rising phenomenon also secondary to improper oral antiseptics use. The present findings highlighted the need to establish more evidence-based and accurate antibiotic prescriptions to sensitize dentists and dental patients to minimize and rationalize the use of antibiotics only when it is indicated and necessary, improve patients’ adherence, and enhance knowledge and awareness of the antimicrobial resistance in dentistry.

Organizations are facing a serious challenge with employee burnout, which leads to a loss of productivity and employee morale. Despite its importance, there is still a knowledge gap in understanding one of the key features of employee burnout, namely, the personal characteristics of employees. This research aims to determine if grit can alleviate employee burnout in organizations. The study conducted a survey of employees in service companies, and results showed that employee grit was negatively associated with burnout. Moreover, the study revealed that grit does not equally affect all three dimensions of burnout, with emotional exhaustion and depersonalization being the most affected by employee grit. Increasing employee grit is therefore a promising strategy for companies that want to mitigate the risk of employee burnout. Full article

This research investigated Latinx and Indigenous Mexican caregivers’ perspectives of the Salton Sea’s environment (e.g., dust concentrations and other toxins) on child health conditions. The Salton Sea is a highly saline drying lakebed located in the Inland Southern California desert borderland region and is surrounded by agricultural fields. Children of Latinx and Indigenous Mexican immigrant families are especially vulnerable to the Salton Sea’s environmental impact on chronic health conditions due to their proximity to the Salton Sea and structural vulnerability. From September 2020 to February 2021, we conducted semi-structured interviews and focus groups with a total of 36 Latinx and Indigenous Mexican caregivers of children with asthma or respiratory distress living along the Salton Sea. A community investigator trained in qualitative research conducted interviews in Spanish or Purépecha, an indigenous language spoken by immigrants from Michoacán, Mexico. Template and matrix analysis was used to identify themes and patterns across interviews and focus groups. Participants characterized the Salton Sea’s environment as toxic, marked by exposure to sulfuric smells, dust storms, chemicals, and fires, all of which contribute to children’s chronic health conditions (e.g., respiratory illnesses such as asthma, bronchitis, and pneumonia, co-presenting with allergies and nosebleeds). The findings have important environmental public health significance for structurally vulnerable child populations in the United States and globally. Full article

Social distancing measures and shelter-in-place orders to limit mobility and transportation were among the strategic measures taken to control the rapid spreading of COVID-19. In major metropolitan areas, there was an estimated decrease of 50 to 90 percent in transit use. The secondary effect of the COVID-19 lockdown was expected to improve air quality, leading to a decrease in respiratory diseases. The present study examines the impact of mobility on air quality during the COVID-19 lockdown in the state of Mississippi (MS), USA. The study region is selected because of its non-metropolitan and non-industrial settings. Concentrations of air pollutants—particulate matter 2.5 (PM2.5), particulate matter 10 (PM10), ozone (O₃), nitrogen oxide (NO₂), sulfur dioxide (SO₂), and carbon monoxide (CO)—were collected from the Environmental Protection Agency, USA from 2011 to 2020. Because of limitations in the data availability, the air quality data of Jackson, MS were assumed to be representative of the entire region of the state. Weather data (temperature, humidity, pressure, precipitation, wind speed, and wind direction) were collected from the National Oceanic and Atmospheric Administration, USA. Traffic-related data (transit) were taken from Google for the year 2020. The statistical and machine learning tools of R Studio were used on the data to study the changes in air quality, if any, during the lockdown period. Weather-normalized machine learning modeling simulating business-as-scenario (BAU) predicted a significant difference in the means of the observed and predicted values for NO₂, O₃, and CO (p < 0.05). Due to the lockdown, the mean concentrations decreased for NO₂ and CO by −4.1 ppb and −0.088 ppm, respectively, while it increased for O₃ by 0.002 ppm. The observed and predicted air quality results agree with the observed decrease in transit by −50.5% as a percentage change of the baseline, and the observed decrease in the prevalence rate of asthma in MS during the lockdown. This study demonstrates the validity and use of simple, easy, and versatile analytical tools to assist policymakers with estimating changes in air quality in situations of a pandemic or natural hazards, and to take measures for mitigating if the deterioration of air quality is detected.

For the timely treatment and management of depression, a high level of depression literacy (DL) is needed. This study aimed to examine the level of DL and factors associated with DL among middle-aged Korean adults and to verify the relationship between DL, depression, and quality of life (QoL). This cross-sectional study included 485 participants aged 40 to 64 years recruited from five provinces in Korea. DL was measured using a 22-item questionnaire and analyzed by multiple linear regression and correlation analysis. The DL level of the participants was moderate and the correct answer rate was 58.6%. In particular, non-pharmacological treatments, differential symptoms, and pharmacological treatments were low. Out of the participants, 25.2% had depression, and the difference in DL between those with and without depression was not statistically significant. The positive factors associated with DL were being female, having higher education, and being employed. DL was not correlated with depression or psychological QoL. However, higher DL was associated with less heavy drinking, normal body mass index, and not smoking. Improving DL can help individuals seek timely professional help and reduce mental health disparities. Further studies should continue to investigate and develop the association between DL and health-related behaviors as well as depression and QoL to effectively treat and manage depression.

This comprehensive review examines critical aspects of evidence-based human kinetics, focusing on bridging the gap between scientific evidence and practical implementation. To bridge this gap, the development of tailored education and training programs is essential, providing practitioners with the expertise and skills to effectively apply evidence-based programs and interventions. The effectiveness of these programs in improving physical fitness across all age groups has been widely demonstrated. In addition, integrating artificial intelligence and the principles of slow science into evidence-based practice promises to identify gaps in knowledge and stimulate further research in human kinetics. The purpose of this review is to provide researchers and practitioners with comprehensive information on the application of scientific principles in human kinetics. By highlighting the importance of evidence-based practice, this review is intended to promote the adoption of effective interventions to optimize physical health and enhance performance.

Aboriginal young people are experts in their own experience and are best placed to identify the solutions to their mental health and wellbeing needs. Given that Aboriginal young people experience high rates of mental health concerns and are less likely than non-Indigenous young people to access mental health services, co-design and evaluation of appropriate mental health care is a priority. Increasing Aboriginal young people’s participation in mental health service reform is key to ensuring services are culturally secure, relevant and accessible. This paper presents first-person accounts from three Aboriginal young people who worked alongside their Elders and in a positive and constructive partnership with mainstream mental health services on a three-year participatory action research project in Perth, Western Australia, in Whadjuk Nyoongar boodja (Country). The young people recount their experiences as participants and co-researchers on a systems change mental health research project and share their views on the importance of privileging Aboriginal youth voices. Their accounts highlight that Aboriginal young people’s participation and leadership must be understood through a decolonising lens and that working in genuine partnership with the community is key to increasing their contact and engagement with mental health care and improving mental health and wellbeing outcomes.

Improving the scale and effectiveness of China’s energy conservation and environmental protection fiscal expenditure is crucial to enhancing the capacity of ecological and environmental governance of China, considering the dual perspectives of pollution governance and public health. This article first explains the mechanism by which national energy conservation and environmental protection fiscal expenditure can improve pollution control and promote public health. Secondly, this article scrutinizes the current status and limitations of China’s fiscal expenditure, highlighting the contribution of fiscal expenditure in the construction of ecological civilization from the standpoints of environmental governance and public health. Additionally, this study empirically uses DEA to measure the efficiency of the government’s fiscal expenditure. Conclusions found that: First, environmental protection fiscal expenditure is mainly focused on technological transformation and pollution control, while relatively little is spent on public health protection. Second, the efficiency of environmental protection fiscal funds is relatively low. These suggestions aim to optimize the positive impact of energy conservation and environmental protection fiscal expenditure for improving pollution governance and promoting public health.

Using baseline data from three partnering federally qualified health centers, we examined factors associated with depressive symptoms among Mexican-origin adults at risk of chronic disease living in three counties in Southern Arizona (i.e., Pima, Yuma, and Santa Cruz). Multivariable linear regression models identified correlates of depressive symptoms for this population controlling for sociodemographic characteristics. Among 206 participants, 85.9% were female and 49% were between 45 and 64 years of age. The proportion of depressive symptoms was 26.8%. Low levels of physical pain and high levels of hope and social support were also reported. Physical pain was positively and significantly related to depressive symptoms (β = 0.22; 95% CI = 0.13, 0.30). Conversely, hope was negatively and significantly associated with depressive symptoms (β = −0.53; 95% CI = −0.78, −0.29). A better understanding of factors related to depressive symptoms among Mexican-origin adults is necessary to fulfill their mental health needs, as well as to achieve health equity and to eliminate health disparities in the US–Mexico border region.

Preemptive statutory language within tobacco minimum legal sales age (MLSA) laws has prohibited localities from enacting stricter laws than state statutes. With the recent uptake of state Tobacco 21 laws in the US, the current landscape of preempted MLSA laws is unknown. This study sought to update the status of preemption in MLSA laws enacted in US states between 2015–2022. A public health attorney reviewed state tobacco MLSA laws (n = 50) and state tobacco control codes, searching for language regarding preemption. When statutes were unclear, case law was reviewed by examining local ordinances that were invalidated by state court decisions. Overall, 40 states enacted Tobacco 21 laws, seven of which expanded or introduced preemption when they increased the MLSA; a total of 26 states (52%) included preemption. Six states (12%) retained ‘savings clauses’ included in the MLSA prior to Tobacco 21, and 18 states (36%) did not mention preemption. Based on the precedent set by state courts, eight of these 18 states may preempt localities from raising their MLSA. Historically, preemption has slowed the diffusion of best practices in tobacco control, and once implemented, the laws are difficult to repeal. The recent expansion of preemption could inhibit the evolution, development, and implementation of effective tobacco control policies. Full article

Generativity is defined as an individual’s concern for and actions dedicated toward the well-being of others, especially youth and subsequent generations. It is a key stage of psychological development from midlife to older age and can be a guiding concept for promoting engagement of older adults in productive and contributive activities, which benefit their well-being. This study examined the longitudinal association between generativity and higher-level functional capacity (HLFC) decline in older Japanese adults. The two-year longitudinal data of 879 older adults aged 65–84 years were analyzed. Participants’ HLFC and generativity were assessed using the Tokyo Metropolitan Institute of Gerontology Index of Competence and the Revised Japanese version of the Generativity Scale, respectively. The binary logistic regression analysis results showed that a higher generativity score was negatively associated with HLFC decline, indicating that generativity effectively prevents HLFC decline over 2 years. On adding the interaction term between generativity and sex to examine whether the protective effect of generativity differed by sex, we found that generativity was especially effective in protecting the HLFC decline in men with higher generativity. The study results highlight the importance of promoting engagement of older adults in generative activities to maintain their HLFC. Full article

Scaling up effective interventions in public health is complex and comprehensive, and published accounts of the scale-up process are scarce. Key aspects of the scale-up experience need to be more comprehensively captured. This study describes the development of a guide for reflecting on and documenting the scale-up of public health interventions, to increase the depth of practice-based information of scaling up. Reviews of relevant scale-up frameworks along with expert input informed the development of the guide. We evaluated its acceptability with potential end-users and applied it to two real-world case studies. The Scale-up Reflection Guide (SRG) provides a structure and process for reflecting on and documenting key aspects of the scale-up process of public health interventions. The SRG is comprised of eight sections: context of completion; intervention delivery, history/background; intervention components; costs/funding strategies and partnership arrangements; the scale-up setting and delivery; scale-up process; and evidence of effectiveness and long-term outcomes. Utilization of the SRG may improve the consistency and reporting for the scale-up of public health interventions and facilitate knowledge sharing. The SRG can be used by a variety of stakeholders including researchers, policymakers or practitioners to more comprehensively reflect on and document scale-up experiences and inform future practice.
