Background: Healthcare workers (HCWs) are at occupational risk from COVID-19. Understanding the profile of infected HCWs is important to guide workplace protections. Objectives: To describe the demographic and clinical characteristics of HCWs infected with COVID-19 and to examine factors associated with vaccination status among infected HCWs. Methods: The study design was cross-sectional, using medical records from health workers working in a tertiary teaching facility in Gauteng, South Africa, from 12 May 2021 to 11 May 2022. The data were analysed using univariate and multiple logistic regression analysis. Statistical significance was set at p < 0.05. Results: A total of 1235 HCW records were included. The age ranged from 17 to 64 years. The median age was 38 years (IQR: 32–48). Nurses accounted for the largest proportion of cases, followed by healthcare assistants and physicians. Female sex, older age, and comorbidity were associated with higher odds of being vaccinated among infected HCWs. Conclusions: This study provides a descriptive profile of HCWs infected with COVID-19 during the third and fourth wave transition in South Africa. The findings highlight demographic and clinical factors linked to vaccination status among infected HCWs and underscore the continued need for infection prevention and control measures to protect frontline staff.

Consumer interest in alternative protein sources has grown rapidly, driven by concerns over health, sustainability and environmental impact. This study investigated perceptions, attitudes and behaviours towards alternative proteins among residents of Piedmont, northwestern Italy. A cross-sectional online and face-to-face survey was conducted between August and October 2023, collecting sociodemographic data, dietary habits, and respondents’ perception on plant-, insect-, snail-, and algae-derived products. Responses from 627 participants were analysed. Approximately one-third reported consuming alternative proteins, with uptake being higher among women, younger adults, and flexitarian respondents. Plant-based alternatives were by far the most frequently consumed, while insect- and snail-based products elicited strong aversion. Curiosity and interest on alternative options predominated among consumers, whereas indifference and disgust—particularly among women and towards animal-derived options—were common among non-consumers. Reported barriers included taste, quality, and safety concerns, with price emerging as a major constraint. These findings indicate that acceptance of alternative proteins is unevenly distributed across demographic groups and product types. Plant-based options currently appear best positioned to facilitate dietary shifts, whereas animal-derived alternatives remain hindered by cultural and sensory barriers. Supporting the protein transition will require strategies to improve affordability, sensory appeal and consumer trust. Full article

This article aims to analyze the role of migration in the process of the third demographic transition (TDT) in the context of key mediating determinants, such as migrants’ religiosity and economic conditions in the countries of origin and settlement. TDT refers to population changes resulting from migration as a demographic compensatory mechanism in countries with a low total fertility rate (TFR). The study is based on a network analysis of keywords in the scientific literature using the Scopus database and VOSviewer. The results point to three main research approaches to TDT—investigating quantitative population changes, the sociodemographic consequences of migration, and its effect on urbanization—and to the fact that economic and axionormative determinants are under-researched. This article contributes to TDT theory, pointing to the need for that theory to include cultural, economic, and axiological factors as key determinants influencing the permanence of TDT.

Population aging is a critical demographic trend in China, creating both challenges and opportunities for sustainable development. As aging alters the structure of the workforce and capital demand, understanding its effect on productivity is essential to managing demographic transitions in China. This study investigates the causal impact of population aging on labor productivity, with a focus on the mediating role of the capital–labor ratio and heterogeneities across industries, skill levels, and regions. Using data from Chinese listed firms between 2011 and 2018, this paper employs industry- and year-fixed effects regression models to control for unobservable heterogeneity and conducts a formal causal mediation analysis. The analysis reveals that population aging significantly enhances labor productivity. Specifically, a one-percentage-point increase in the old-age dependency ratio is associated with a 1.47% increase in firm-level labor productivity. The capital–labor ratio emerges as a critical mechanism, mediating the relationship between aging and productivity by incentivizing firms to increase capital intensity in response to labor shortages. Approximately 72.4% of the total effect is mediated through changes in capital intensity. The findings highlight notable heterogeneities. Labor-intensive firms and low-skilled worker segments experience stronger productivity gains from aging compared with their capital-intensive and high-skilled counterparts. At the regional level, the productivity effects are most pronounced in first- and second-tier cities, while third-tier cities show negligible impacts, reflecting resource and structural constraints. This study underscores the dual role of population aging as a challenge and an opportunity. Policy recommendations include (1) expanding targeted fiscal support for capital investment and automation in aging-intensive industries; (2) promoting vocational training programs tailored to older workers and digital skills development; and (3) strengthening infrastructure and institutional capacity in third-tier cities to better absorb productivity spillovers from demographic adjustment. By addressing these demographic and productivity linkages, the study contributes to achieving Sustainable Development Goals 8 (Decent Work and Economic Growth), 9 (Industry, Innovation, and Infrastructure), and 10 (Reduced Inequalities), by promoting inclusive productivity growth, enhancing industrial adaptation to demographic change, and reducing regional and skill-based disparities.These findings offer valuable insights for policymakers and businesses navigating the complexities of aging economies.

Background: A knowledge gap exists on population understanding and perspectives of menopause. To better support females, it is important to understand different population groups’ perceived knowledge of and attitudes towards menopause. This study explored perceived knowledge of menopause, awareness of menopausal symptoms, perceived negative impacts of menopause on females’ lives, and attitudes towards menopause. Methods: A national cross-sectional survey (n = 1020) was conducted with residents in Wales aged 16+ years as part of a larger population panel using a multi-method approach (online, telephone, and face-to-face), stratified by NHS health board area, age, sex, deprivation, and ethnicity. Questions on menopause were developed by the research team. Results: Nearly a third (31.1%) of participants reported having low knowledge of menopause, with younger age groups and males reporting the lowest knowledge. Hot flushes were the most recognised menopause symptom (92.2%). The symptom with the greatest gap in awareness between age groups, sexes, and deprivation quintiles was problems with memory or concentration. Most participants perceived menopause to have a large negative impact on females’ mental health (76.1%), working life (69.7%) and physical health (69.6%). Females and 30–49-year-olds were more likely to perceive large negative impacts across all three domains. Most participants (77.8%) agreed that more public discussion is needed on menopause to increase understanding. The greatest support for increasing public discussion was found amongst females and people aged 30–49 years old. Conclusions: At a population level, perceived knowledge of menopause and associated symptoms and perceived impacts on females’ lives varied across socio-demographic groups. While males were less knowledgeable than females, most males perceived negative impacts on females’ lives and agreed with action to improve the menopausal environment. Increasing knowledge in those who experience menopause and in those who support those who experience menopause could help females have a more positive transition process. Full article

As an essential prerequisite to the genealogical study of Jews, some elements of Jewish demographic history are provided in a long-term transnational perspective. Data and estimates from a vast array of sources are combined to draw a profile of Jewish populations globally, noting changes in geographical distribution, vital processes (marriages, births and deaths), international migrations, and changes in Jewish identification. Jews often anticipated the transition from higher to lower levels of mortality and fertility, or else joined large-scale migration flows that reflected shifting constraints and opportunities locally and globally. Cultural drivers typical of the Jewish minority interacted with socioeconomic and political drivers coming from the encompassing majority. The main centers of Jewish presence globally repeatedly shifted, entailing the intake within Jewish communities of demographic patterns from significantly different environments. During the 20th century, two main events reshaped the demography of the Jews globally: the Shoah (destruction) of two thirds of all Jews in Europe during World War II, and the independence of the State of Israel in 1948. Mass immigration and significant convergence followed among Jews of different geographical origins. Israel’s Jewish population grew to constitute a large share—and in the longer run—a potential majority of all Jews worldwide. Since the 19th century, and with increasing visibility during the 20th and the 21st, Jews also tended to assimilate in the respective Diaspora environments, leading to a blurring of identificational boundaries and sometimes to a numerical erosion of the Jewish population. This article concludes with some implications for Jewish genealogical studies, stressing the need for contextualization to enhance their value for personal memory and for analytic work. Full article

Transitioning from fossil to renewable energy is a global challenge, especially for countries with large fossil-fuel reserves and exports, such as Iran. This study analyses agricultural students’ knowledge of, attitudes toward, and perceptions of renewable energies in the agriculture sector in Guilan Province in Iran. The research was based on a structured questionnaire comprising three sections: (i) respondents’ socio-demographics; (ii) practicality and relevance of academic material and curriculum; and (iii) respondents’ knowledge of and attitudes and perceptions toward renewable energies in agriculture. The results showed that students’ attitudes regarding renewable energies ranked highest, and their perception was lowest. The results also showed a positive and significant relationship between the respondents’ knowledge, marital status, age, and level of education. Moreover, respondents’ age and educational level significantly impacted their attitudes. Cluster analysis divided students’ behavior into three different clusters. These clusters were most affected by attitude. In clustering students’ behavior towards using renewable energies, 38.5%, 33.5%, and 28% of respondents were positioned in the first, third, and second clusters, respectively. This is a pioneering study analyzing agricultural students’ behavior regarding renewable energies in agriculture in Guilan Province, Iran. The results of this study can assist agricultural organizations, politicians in the field of energy, and local authorities in promoting sustainable energy in Guilan Province. Full article

Increased HIV drug resistance (HIVDR) with antiretroviral therapy (ART) rollout may jeopardize therapeutic options, especially in this era of transition to fixed-dose tenofovir-lamivudine-dolutegravir (TLD). We studied acquired HIVDR (ADR) patterns and describe potentially active drugs after first- and second-line failure in resource-limited settings (RLS) like Cameroon. A laboratory-based study with 759 patients (≥15 years) experiencing virological failure was carried out at the Chantal Biya International Reference Centre (CIRCB), Yaoundé, Cameroon. Socio-demographic, therapeutic and immunovirological data from patient records were analysed according to HIV-1 genotypic profiles. Median (IQR) ART-duration was 63 (50–308) months. Median CD4 and viremia were 153 (IQR:50–308) cells/mm³ and 138,666 (IQR:28,979–533,066) copies/mL, respectively. Overall ADR was high (93.4% first-line; 92.9%-second-line). TDF, potentially active in 35.7% of participants after first-line and 45.1% after second-line, suggested sub-optimal TLD-efficacy in second-line (64.3%) and third-line (54.9%). All PI/r preserved high efficacy after first-line failure while only DRV/r preserved high-level efficacy (87.9%) after second-line failure. In this resource-limited setting (RLS), ADR is high in ART-failing patients. PI/r strategies remain potent backbones for second-line ART, while only DRV/r remains very potent despite second-line failure. Though TLD use would be preferable, blind use for second- and third-line regimens may be sub-optimal (functional monotherapy with dolutegravir) with high risk of further failure, thus suggesting strategies for selective ART switch to TLD in failing patients in RLS.

Latin America and the Caribbean (LAC) contain more tropical high-biodiversity forest than the remaining areas of the planet combined, yet experienced more than a third of global deforestation during the first decade of the 21st century. While drivers of forest change occur at multiple scales, we examined forest change at the municipal and national scales integrated with global processes such as capital, commodity, and labor flows. We modeled multi-scale socioeconomic, demographic, and environmental drivers of local forest cover change. Consistent with LAC’s global leadership in soy and beef exports, primarily to China, Russia, the US, and the EU, national-level beef and soy production were the primary land use drivers of decreased forest cover. National level gross domestic product (GDP), migrant worker remittances and foreign investment, along with municipal-level temperature and area, were also significantly related to reduced forest cover. This challenges forest transition frameworks, which theorize that rising GDP and intensified agricultural production should be increasingly associated with forest regrowth. Instead, LAC forest change was linked to local, national, and global demographic, dietary and economic transitions, resulting in massive net forest cover loss. This suggests an urgent need to reconcile forest conservation with mounting global demand for animal protein. Full article

The study of the nutritional transition in Spain must combine sources concerning the health conditions and the nutritional profile of the population. Such an approximation to the issue is, as a rule, not possible until the two final decades of the 20th century. However, the report on the nutritional status of the Spanish army, undertaken by the American Interdepartmental Committee on Nutrition for National Defence (ICNND) in 1958, combines both approaches. The report is based on the medical examination of 10727 army drafts. First, the article contextualised the report’s sample geographically and demographically; second, it validated the variables used statistically; and third, it explored the relationship between the diseases diagnosed, the biomarkers yielded by blood and urine tests, and the diet. The main results were as follows: (a) the report confirmed that the military population under examination did not suffer from severe dietary shortcomings; (b) the sample presents a double bias, geographical (overrepresentation of southern provinces) and institutional (underrepresentation of the land forces).

Sub-Saharan African (SSA) countries face a growing burden of cardiovascular disease (CVD), attributed to economic, nutritional, demographic, and epidemiological transitions. These factors increase the prevalence of CVD risk factors, and the CVD burden overlaps with a high prevalence of infectious diseases. This review aimed to understand CVD healthcare utilization determinants and levels in SSA. We conducted a systematic search of the literature on major databases for the period 2008–2018 using exhaustive combinations of CVD and utilization indicators as search terms. Eighteen studies from eight countries were included in this review. Most studies (88.8%) followed the quantitative methodology and largely focused on inpatient stroke care. Two-thirds of patients sought care within 24 h of suffering a stroke, and the length of stay (LOS) in hospital ranged between 6 and 81 days. Results showed a rising trend of CVD admissions within total hospital admissions. Coverage of physiotherapy services was limited and varied between countries. While few studies included rural populations, utilization was found to be negatively associated with rural residence and socioeconomic status. There is a need to extend healthcare provision in SSA to ensure access to the CVD continuum of care. Full article

This study aimed to examine factors associated with maternal wellbeing at four months post-partum in the Irish context. Socio-demographic, health behaviour and infant feeding data were collected in pregnancy, at birth and at 17 weeks post-partum. Maternal distress, body image and resilience were measured at 17 weeks post-partum. Binary logistic regression predicted maternal distress and statistical significance was taken at p < 0.05. One hundred and seventy-two women were followed-up in pregnancy, at birth and at 17 weeks post-partum. Three in five (61.6%, n106) initiated breastfeeding. At 17 weeks post-partum, 23.8% (n41) were exclusively or partially breastfeeding and over a third (36.0%, n62) of all mothers were at risk of distress. In multivariate analyses, independent predictors of distress included: low maternal resilience (p < 0.01, odds ratio (OR): 7.22 (95% confidence interval [CI]: 2.49–20.95)); unsatisfactory partner support (p = 0.02, OR: 3.89 (95% CI: 1.20–12.65)); older age (p = 0.02, OR: 1.11 (95% CI: 1.02–1.21)); and breastfeeding (p = 0.01, OR: 2.89 (95% CI: 1.29–6.47)). Routine assessment of emotional wellbeing and targeted interventions are needed to promote a more healthful transition to motherhood among women in Ireland. Full article

There is increasing evidence linking early life adiposity to disease risk later in life. This study aims at determining the prevalence and correlates of overweight and obesity among preschoolers in Lebanon. A national cross-sectional survey was conducted amongst 2–5 years old children (n = 525). Socio-demographic, lifestyle, dietary, and anthropometric data were obtained. The prevalence of overweight and obesity was estimated at 6.5% and 2.7%, respectively. Based on stepwise logistic regression for the prediction of overweight and obesity (combined), the variance accounted for by the first block (socioeconomic, parental characteristics) was 11.9%, with higher father’s education (OR = 5.31, 95% CI: 1.04–27.26) and the presence of household helper (OR = 2.19, 95% CI: 1.05–4.56) being significant predictors. The second block of variables (eating habits) significantly improved the prediction of overweight/obesity to reach 21%, with eating in front of the television (OR = 1.07, 95% CI: 1.02–1.13) and satiety responsiveness (OR = 0.83, 95% CI: 0.70–0.99) being significantly associated with overweight/obesity. In the third block, fat intake remained a significant predictor of overweight/obesity (OR = 2.31, 95% CI: 1.13–4.75). This study identified specific risk factors for preschool overweight/obesity in Lebanon and characterized children from high socioeconomic backgrounds as important target groups for preventive interventions. These findings may be of significance to other middle-income countries in similar stages of nutrition transition. Full article

The rise of the middle classes in developing countries and the associated epidemiological transition raises the importance of assessing this population group’s awareness of the causes of obesity and effective weight control strategies in order to develop effective health promotion strategies. The study aimed to examine the perceptions of the causes of obesity and weight control strategies held by middle class household food providers in Melbourne, Singapore, Shanghai, Indonesia and Vietnam. An online survey was conducted in late 2013, early 2014 among 3945 respondents. Information about body weight concerns, perceived causes of obesity, effectiveness of weight control methods, demographics, self-reported height and weight, and personal values was elicited. Confirmatory factor analyses (CFA) derived nine reliable factors which were used in structural equation modelling (SEM). Two thirds of respondents were trying to change their body weight, of them, 71% were trying to lose weight. The CFA and SEM showed that demographics, region of residence, personal values and perceptions of the causes of obesity (Unhealthy food behaviours, influences Beyond personal control and Environmental influences) had direct and indirect associations with three weight control methods factors, named: Healthy habits, Eat less, sit less, and Dieting. Middle class food providers in the study regions share public health views of obesity causation and personal weight control. These findings could inform public health and food policies, and the design of public health interventions and communications. Further research is required among lower socio economic status (SES) populations. Full article
