Mental disorders and impairments are part of the occupational risk for emergency personnel. This study examines the impact of a deadly knife attack on police officers’ mental health. Aims: We hypothesized that police officers who knew the deceased team member would report higher levels of psychological distress compared to those who did not, regardless of the deployment status. Methods: Six months after a fatal knife attack in which a police officer was killed, a total of N = 254 officers participated in the study. Of these, n = 115 reported knowing the victim personally, n = 126 did not (n = 78 deployed; n = 176 not deployed), while n = five did not provide any information. Posttraumatic stress disorder (PTSD), posttraumatic stress symptoms (PTSS), anger and adverse childhood experiences (ACEs) were assessed using questionnaires. Chi-square tests examined group differences in probable PTSD prevalence; t-tests assessed differences in anger and Posttraumatic Stress Disorder Checklist for DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition; DSM-5; PCL-5) symptom scores. Linear regression analyses tested deployment, acquaintance with the victim, gender, and childhood emotional neglect as predictors. Results: Police officers who personally knew the deceased colleague exhibited significantly higher PTSS scores. In addition, the deployed group showed significantly higher trait anger than the non-deployed. Acquaintance with the victim and emotional neglect in childhood were significantly related to negative cognitions, whereas deployment to the knife attack or gender were not. Discussion: Police officers with a personal connection to the deceased showed significantly higher mental health impact than those with direct exposure alone, placing them in a higher-risk group due to increased exposure to feelings of guilt and shame due to their professional role. Police officers who were emotionally neglected in their childhood may be more prone to negative cognitions in adulthood, when faced with critical events. These results underline the importance of addressing risk factors in both pre-deployment training and post-event debriefing, especially with regard to anger management after major critical incidents.

Background: Chronic pain is a serious health issue associated with significant functional and emotional impairment. Chronic pain acceptance, which can be described as engaging in valued activities despite ongoing pain, is associated with better psychological adjustment and quality of life. This study aimed to translate the Eight-Item Chronic Pain Acceptance Questionnaire (CPAQ-8) into Croatian and investigate its reliability and validity. Methods: A total of 229 outpatients with chronic musculoskeletal pain completed the Croatian version of the CPAQ-8, as well as the SF-36 Health Status Questionnaire (SF-36), the Hospital Anxiety and Depression Scale (HADS), the Pain Catastrophizing Scale (PSC), and the Numeric Pain Rating Scale (NRS). Results: The Croatian version of the CPAQ-8 demonstrated good internal consistency for the total score and its subscales, and the exploratory factor analysis revealed the original two-factor structure. Concurrent validity was supported through theoretically consistent correlations with psychological distress, quality of life, and pain-related constructs. Conclusion: The Croatian version of the CPAQ-8 is a reliable and valid instrument for assessing pain acceptance in patients with chronic musculoskeletal pain and can be confidently used in both clinical practice and research settings.

Background and Objectives: Chronic kidney disease (CKD) and maintenance hemodialysis (HD) are frequently associated with psychological distress and impaired health-related quality of life (HRQoL). However, the relationships between depressive, anxiety, and stress symptoms, clinical factors, and HRQoL remain insufficiently understood in routine care. This study aimed to assess the prevalence of psychological distress and to explore cross-sectional correlates of kidney disease-specific and generic HRQoL in Romanian patients receiving long-term HD, providing one of the first detailed characterizations of these relationships in an Eastern European maintenance HD cohort. Materials and Methods: This single-center cross-sectional study included 125 adult patients undergoing maintenance HD for at least one year. Baseline assessment comprised socioeconomic, demographic and clinical and paraclinical data, including Charlson Comorbidity Index (CCI), dialysis adequacy (spKt/V), cognitive function, psychological distress assessed with the Depression, Anxiety and Stress Scale (DASS-21R), and HRQoL evaluated using the Kidney Disease Quality of Life Short Form (KDQOL-SF™ 1.3). HRQoL domains and physical and mental component summary scores (PCS, MCS) were analyzed using descriptive statistics, correlation analyses, and multivariable linear regression. Follow-up assessments at approximately one year were summarized descriptively. Results: Disease-specific HRQoL revealed marked impairment in perceived disease burden and work status, while physical HRQoL was substantially reduced (PCS 36.5 ± 9.6). Mental HRQoL was relatively preserved (MCS 48.8 ± 8.8). At baseline, 48.0% of patients reported at least mild depressive symptoms, 34.4% anxiety symptoms, and 44.0% stress symptoms. spKt/V showed a modest association with PCS. Psychological distress demonstrated weak associations with HRQoL; stress was independently associated with lower MCS, with limited explained variance (R² ≤ 0.15). Conclusions: Psychological distress is common among Romanian HD patients and is cross-sectionally associated with markedly impaired physical HRQoL. While the present design does not allow causal inferences, these findings support the implementation of routine psychological screening and the consideration of targeted psychosocial interventions in HD care.

Background/Objectives: Family caregivers of individuals with dementia frequently experience substantial psychological distress, yet their emotional responses are heterogeneous. Depression, anxiety and psychological well-being may co-occur in distinct patterns, and socio-economic resources such as education and income are often hypothesized to buffer caregiver distress. This study aimed to identify latent psychological profiles among dementia caregivers and to examine whether education and income moderate the association between affective symptoms and well-being. Methods: A cross-sectional study was conducted with 73 family caregivers of dementia patients attending the Neurology–Psychiatry Department of C.F.2 Clinical Hospital, Bucharest (November 2023–April 2024). Participants completed the PHQ-9 (depression), the COVI Anxiety Scale and Ryff’s Psychological Well-Being Scales. Care recipients’ cognitive status was extracted from medical records using the MMSE. Gaussian Mixture Modeling was used for latent profile analysis (LPA). Between-profile differences were examined using one-way ANOVAs and Tukey post-hoc tests and Pearson correlations were used to assess associations between affective symptoms and psychological well-being, and examined whether education and income were associated with profile membership and psychological well-being. Results: LPA supported a three-profile solution: (1) lower depressive symptoms with moderate anxiety (33%), (2) severe combined depression and anxiety (18%) and (3) moderately severe depression with severe anxiety (49%). Profiles differed significantly in depressive symptom severity, whereas anxiety severity did not differ significantly across profiles. Caregivers in Profile 3 (moderately severe depression–severe anxiety) reported significantly higher overall psychological well-being than those in Profile 1 (moderate depression–moderate anxiety). In contrast, caregivers in Profile 2 (severe depression–severe anxiety), who exhibited the highest affective symptom burden, showed intermediate levels of overall well-being, with comparatively lower scores on specific dimensions such as purpose in life. Depressive symptoms were weakly but significantly associated with autonomy and self-acceptance, whereas anxiety symptoms showed no significant associations with psychological well-being. Education level and household income were not significantly associated with profile membership or psychological well-being. Conclusions: Family caregivers of individuals with dementia can be meaningfully described as forming three exploratory psychological profiles characterized by different configurations of depressive and anxiety symptoms. These findings indicate that caregiver distress does not follow a simple severity gradient and that psychological well-being is not solely determined by symptom burden. Socio-economic characteristics did not account for differences in caregiver adjustment, underscoring the importance of individualized psychological assessment and tailored interventions to support caregiver mental health.

Psychological stress is increasingly investigated as a potentially modifiable factor in male infertility, in part through oxidative stress. This narrative review synthesizes mechanistic and translational evidence linking stress-related neuroendocrine activation and coping behaviors with redox imbalance in the male reproductive tract. Chronic activation of the hypothalamic–pituitary–adrenal axis and sympathetic outflow elevates glucocorticoids and catecholamines. In controlled animal stress paradigms, this is accompanied by suppression of the hypothalamic–pituitary–gonadal axis and by immune and metabolic changes that favor reactive oxygen species generation. The resulting oxidative stress may reduce Leydig cell steroidogenesis, impair testicular and epididymal function, and induce lipid peroxidation, mitochondrial dysfunction, and sperm DNA fragmentation. In such models, these lesions, together with apoptosis of germ and supporting cells, are associated with lower sperm concentration, reduced motility, compromised viability, and diminished fertilizing potential. Overall, preclinical animal studies using defined stress paradigms provide experimental evidence consistent with causal effects of stress on oxidative injury and reproductive impairment in preclinical settings. Human studies linking perceived stress, anxiety/depression, and disturbed sleep to adverse semen parameters and oxidative biomarkers are summarized. However, the human evidence is predominantly associative, and the available studies are cross sectional and remain vulnerable to residual confounding and reverse causality. Potential effect modifiers, including smoking, alcohol use, and circadian disruption, are also discussed as contributors to heterogeneity across clinical studies. Standardized assessment of stress biology and redox status, longitudinal designs aligned with spermatogenic timing, and well-powered intervention trials are needed to define dose–response relationships and support individualized prevention and care.

Background/Objectives: Childhood obesity remains a major public health issue, particularly in Mediterranean countries such as Greece. Although parental influences on children’s weight have been extensively studied, fewer studies have jointly examined parental mental health, feeding practices, sociodemographic factors, and biological stress markers. This study aimed to investigate associations between psychological status, educational level, feeding behaviors, and children’s Body Mass Index (BMI) in a Greek sample. A pilot assessment of salivary cortisol was included in evaluating its feasibility as an objective biomarker of parental stress. Subjects and Methods: A total of 103 parent–child dyads participated in this cross-sectional study. Children’s BMI was classified using World Health Organization (WHO) growth standards. Parental stress, anxiety, and depressive symptoms were assessed using the Perceived Stress Scale-14 (PSS-14) and the Depression Anxiety Stress Scale-21 (DASS-21) questionnaires. Feeding practices were evaluated with the Comprehensive Feeding Practices Questionnaire (CFPQ). Statistical analyses included Pearson correlations, independent samples t-tests, one-way ANOVA, Mann–Whitney U, and Kruskal–Wallis tests. A subsample provided saliva samples for cortisol analysis to assess feasibility and explore the potential associations with parental stress indicators. Results: Parental BMI showed a strong positive association with child BMI (p = 0.002). Higher parental anxiety (p = 0.002) and depression (p = 0.009) were also associated with increased child BMI. Restrictive (p < 0.001) and emotion-driven (p < 0.001) feeding practices were associated with higher child BMI, whereas monitoring (p = 0.013) and health-promoting feeding practices (p = 0.001) appeared protective. Lower parental education was related to a higher BMI in both parents (p = 0.001) and children (p = 0.002) and to more frequent use of restrictive feeding strategies (p = 0.001). WHO charts identified a greater proportion of children as overweight or obese compared with the Centers for Disease Control and Prevention (CDC) criteria. The analysis showed statistically significant differences between the two classification systems (χ² (4) = 159.704, p < 0.001), indicating that BMI categorization varies considerably depending on the reference system used. No significant associations were observed with residential environment or salivary cortisol, likely due to the limited size of the pilot biomarker subsample. Conclusions: The findings highlight the combined effect of parental mental health status, educational level, and feeding practices on child BMI within the Greek context. The preliminary inclusion of a biological stress marker provides added value to the existing research in this area. These results underscore the importance of prevention strategies that promote parental psychological wellbeing and responsive feeding practices while addressing socioeconomic disparities to reduce the childhood obesity risk.

Background/Objectives: Nurses are susceptible to compassion fatigue due to the nature of their professional responsibilities. Factors contributing to this vulnerability include daily patient interactions and organizational elements within their work environment, as well as work-related stress and sociodemographic characteristics, including age, marital status, years of professional experience, and, notably, gender. This research investigates the relationship between compassion fatigue and the levels of anxiety and depression, as well as the professional quality of life among nurses providing care to dementia patients in Greece. Methods: A cross-sectional survey was carried out with 115 nurses working in dementia care centers in Greece. The Hospital Anxiety and Depression Scale (HADS), the Professional Quality of Life Scale (ProQOL-5), and the participants’ personal, demographic, and professional information were all included in an electronic questionnaire. Multiple regression analysis was used. Results: A total of 42.6% of nurses rated their working environment as favorable. Additionally, 23.5% of the sample exhibited high levels of compassion satisfaction, whereas 46.1% demonstrated low levels of burnout. Female gender (p = 0.022) and a higher family income (p = 0.046) was positively associated with compassion satisfaction. Regression analysis indicated that elevated symptoms of anxiety and depression were found to correlate with decreased compassion satisfaction, increased burnout, and heightened secondary post-traumatic stress. Conclusions: Engaging in the care of patients with dementia, particularly throughout the pandemic period, has underscored a pronounced susceptibility to compassion fatigue, physical fatigue, pain, psychological stress, and a reduced quality of life. These results highlight the importance for nursing management to adopt specific organizational measures, including proper staffing levels, balancing workloads, and conducting routine mental health assessments.

Background: Adolescence is a sensitive period for psychological, academic, and social development, and sports participation has been described as a potential protective factor for academic performance and psychological well-being. However, limited research has examined the combined influence of sports involvement, sport type, and family background on adolescents’ academic and psychological outcomes. This study aimed to investigate the associations between organized sport participation, sport type (football vs. judo), psychological well-being, psychosomatic symptoms, academic performance, and family socioeconomic background among adolescent boys. Methods: The sample consisted of 52 boys aged 11–14 years from a rural school, divided into football players (n = 13), judo athletes (n = 13), non-athletes (n = 13), and a contextual subgroup of students with special educational needs (SEN; n = 13), with the latter included for exploratory purposes only. Data included school-record-based academic performance and validated self-report measures of life satisfaction, depressive symptoms, psychosomatic complaints, perceived physical fitness, and socioeconomic background. Results: Athletes demonstrated significantly higher academic achievement than non-athletes in overall grade point average (p < 0.001), mathematics (p < 0.001), Romanian (p < 0.001), English (p = 0.03), and Hungarian (p < 0.001). They also reported higher life satisfaction (p < 0.001) but simultaneously showed slightly elevated depressive symptom scores (p < 0.001), indicating a paradoxical pattern of concurrent psychosocial benefits and psychological strain. Parental education (p < 0.001), parental occupational status (p = 0.01), and fathers’ occupational position (p = 0.02) were significantly higher among athletes’ families. Perceived physical fitness was also rated higher by athletes (p < 0.001). No significant differences were found in body mass index, family structure, or most psychosomatic symptoms. Conclusions: Sport participation was associated with more favorable academic and psychological indicators, yet also with elevated depressive symptoms, highlighting the dual nature of organized sport during adolescence. Future research should apply longitudinal designs, include female participants, and incorporate objective indicators of training load. Full article

Introduction: The COVID-19 pandemic had significant effects on mental health and lifestyle behaviours, especially among university students who experienced academic disruptions, social isolation, and fewer social interactions. Alcohol consumption has long been part of student culture. Still, the influence of post-pandemic academic reintegration on drinking patterns and psychological distress remains relatively unexplored, particularly in countries like Portugal, where student traditions heavily shape consumption habits. This study aimed to describe the prevalence of alcohol consumption, depression, anxiety, and stress in a sample of Portuguese university students during the post-pandemic academic period, and to explore associations with sociodemographic variables. Methods: A cross-sectional study was conducted in November 2021 with 90 students from a private higher education institution in northern Portugal. Data were collected via an online questionnaire including sociodemographic information, the Alcohol Use Disorders Identification Test (AUDIT), and the Depression, Anxiety and Stress Scale (DASS-21). Result: The majority of the participants were not at risk of alcohol addiction (95.3%). In total, 15.1% of students reported anxiety symptoms ranging from severe to extremely severe. A binomial logistic regression was performed to ascertain the effects of being away from home and psychological distress (DASS-42 score), on the likelihood that participants were at risk of alcohol addiction (Level 3 and 4 in the AUDIT scale). The logistic regression model was statistically significant, χ²(2) = 9.20, p = 0.010. Living away from home was associated with a substantially lower likelihood of high-risk status (B = −2.79, p = 0.034), corresponding to an odds ratio of 0.06, indicating a strong protective effect. DASS-42 total score was positively associated with high-risk status (B = 0.04, p = 0.039), such that higher psychological distress increased the odds of being classified as high risk. Conclusions: The findings reveal a low prevalence of alcohol risk but heightened symptoms of anxiety, depression, and stress. Psychological distress notably increases the likelihood of hazardous alcohol use, emphasising the importance of targeted mental health and alcohol-use interventions among university students.

Background/Objectives: Parkinson’s disease is the second most common neurodegenerative disorder, affecting patients’ daily lives in multiple domains, including functional status, health-related quality of life, and psychological well-being. This study examined the relationship between self-reported global activity level, functional status, Health Related QoL (HRQoL), and psychological state among patients with Parkinson’s disease in Greece. Methods: Thirty volunteers (mean age = 69.07, SD = 11.24), members of the Greek Parkinson’s Patients and Caregivers Association, completed (a) the Parkinson’s Disease Questionnaire to evaluate HRQoL and (b) the Hospital Anxiety and Depression Scale (HADS) to assess psychological state. Participants then performed (a) the Five Times Sit to Stand Test (FTSST) and (b) the Berg Balance Scale (BBS) to evaluate functional status. All questionnaires and the test used in the present study have been validated in Greek. Correlation analysis with Spearman r tests with Bonferroni correction was performed between the above variables. Subsequent linear regression models were used to identify independent predictors of HRQoL and balance using SPSS 29.0.2.0. Results: Participants reported elevated anxiety (M = 9.67, SD = 4.44) and depressive symptoms (M = 8.97, SD = 4.08), alongside relatively high HRQoL scores (M = 40.09, SD = 18.40). Impaired functional performance was observed, with 22 participants failing to complete the FTSST within 16 s and 16 scoring below 40 on the BBS. Functional status was strongly correlated with HRQoL (r = −0.696, p < 0.001) and activity level (r = −0.521, p < 0.008). Depression was also significantly associated with poorer HRQoL (r = 0.618, p < 0.008) and lower activity levels (r = −0.545, p < 0.008). Regression analyses revealed that balance (β = −0.526), disease duration (β = 0.437), anxiety (β = 0.411), and lower limb function (β = −0.351) were significant independent predictors of HRQoL (R² = 0.785; F(9, 20) = 12.69; p < 0.001), while HRQoL (β = −0.738) and lower limb function (β = −0.391) independently predicted balance (R² = 0.699; F(9, 20) = 4.72; p = 0.002), suggesting a bidirectional relationship between physical function and subjective well-being. Conclusions: Activity level, HRQoL, functional status, and psychological state in patients with Parkinson’s disease are interrelated factors. Increased levels of anxiety and depression, as well as reduced HRQoL, were observed. The findings point to a potentially reinforcing cycle between poor balance and diminished quality of life, with anxiety and age playing key roles. Overall, the results illustrate that functional, psychological, and HRQoL measures interact in complex ways, emphasizing the multidimensional profile of patients with Parkinson’s disease. Further studies with larger samples are required to confirm these findings. Full article

The COVID-19 pandemic exacerbated structural, social, economic, and racial inequalities affecting immigrant, refugee, and asylum-seeking men—vulnerable populations often overlooked in men’s health research. This study investigated the health conditions of immigrant, refugee, and asylum-seeking men during the COVID-19 pandemic. A scoping review was conducted following Joanna Briggs Institute guidance, and a qualitative lexical analysis (text-mining of standardized study syntheses) was performed in IRaMuTeQ using similarity analysis, descending hierarchical classification, and factorial correspondence analysis. We identified 93 studies published between 2020 and 2023 across 35 countries. The evidence highlighted vaccine hesitancy, high epidemiological risks (infection, hospitalization, and mortality), barriers to accessing services and information, socioeconomic vulnerabilities, psychological distress (e.g., anxiety and depression), and structural inequalities. Findings were synthesized into four integrated thematic categories emphasizing the role of gender constructs in help-seeking and gaps in governmental responses. Most studies focused on immigrants, with limited evidence on refugees and especially asylum seekers; therefore, conclusions should be interpreted cautiously for these groups. Overall, the review underscores the urgency of multisectoral interventions, universal access to healthcare regardless of migration status, culturally and linguistically appropriate outreach, and gender-sensitive primary care strategies to support inclusive and resilient health systems.

Background: Despite its crucial role in overall health, oral health is frequently overlooked within healthcare systems, partly due to the misconception that oral diseases are neither life-threatening nor directly disabling. This perception has led to an underestimation of the psychological, social, and economic burden associated with oral diseases. Τhe present study aimed to assess oral health status and oral health-related quality of life among dental patients attending a public Special Care Center in Greece. Methods: A cross-sectional study was conducted among 400 dental patients aged 18 years and older who visited a public Special Care Center for a routine check-up or a dental problem between September and October 2024. Data was collected through personal interviews and clinical examinations after informed consent was obtained. Oral health-related quality of life was evaluated using the Oral Health Impact Profile-14 (OHIP-14) and the Oral Impacts on Daily Performance (OIDP) questionnaires. Categorical variables were presented as absolute and relative frequencies, while quantitative variables were summarized as mean, standard deviation, median, minimum, and maximum. Normality was assessed using the Kolmogorov–Smirnov test. Bivariate analyses and multivariate linear regression models were performed, with statistical significance set at p < 0.05. Statistical analyses were conducted using IBM SPSS 23.0. Results: The majority of participants were female (56.3%) with a mean age of 50.4 years (SD = 14.9). Overall oral health-related quality of life was moderate (OHIP-14: Mean = 21.0, SD = 14.8; OIDP: Mean = 14.0, SD = 12.8). Patients who attended the center due to a dental problem reported significantly poorer oral health outcomes than those attending routine check-ups (p < 0.001). Poorer self-rated oral health, having ≥12 missing teeth, prosthetic restoration, and foreign nationality were significantly associated with worse oral health-related quality of life. Conclusions: Dental patients attending the Special Care Center demonstrated moderate oral health status, which was associated with psychological distress, physical disability, and social limitations. These findings underline the need for targeted public oral health interventions, especially for vulnerable population groups. Full article

Background/Objectives: Frailty is a complex geriatric syndrome that requires a comprehensive evaluation. This approach should consider not only physical symptoms but also cognitive, psychological, functional, nutritional, and social aspects. Nutritional status is a critical and modifiable factor, making it a key area for intervention in the prevention and management of frailty. Therefore, a scoping review was conducted to determine the effectiveness of nutritional intervention in frail/pre-frail older adults. Methods: We adopted the PRISMA-Scoping approach, and we sought studies published in MEDLINE and Scopus databases. Results: We screened 3038 studies and finally we included a total of 19 studies. The interventions included nutritional education, counseling, and supplementation, most in combination with exercise. Nutritional interventions improved frailty status, physical performance, functional status, and quality of life in older adults. Conclusions: Consequently, this scoping review indicates that multifactorial interventions combining nutritional interventions with physical activity are clearly more effective than a single approach in improving the quality of life of older patients with frailty. These provisional findings may generate hypotheses for policymakers to consider multifaceted interventions for older patients with frailty. Full article

Background: Obesity is characterized by chronic low-grade inflammation and metabolic disturbances, including an altered tryptophan (Trp) catabolism through the kynurenine pathway (KP). Since the KP is closely linked to immune activity, energy metabolism, and hepatic function, modulating its flux through lifestyle interventions has gained interest as a potential therapeutic strategy. Objective: This exploratory study aimed to investigate the impact of a structured 12-week weight loss program (WLP) on serum KP metabolites in a sample of Mexican women with obesity. Methods: This study involved a pre–post-intervention design conducted in twenty-four women with clinically diagnosed obesity from the Mexican Navy who underwent a structured 12-week weight loss program combining a hypocaloric diet with moderate-intensity aerobic exercise; no control group was included. Anthropometric parameters, serum biochemistry, and circulating levels of Trp, kynurenine (KYN), kynurenic acid (KYNA), and 3-hydroxykynurenine (3-HK) were assessed before and after intervention. Psychological assessments of anxiety and depression were also conducted in a subset of participants. Results: The WLP significantly reduced body weight, BMI, fat mass, fasting insulin, and C-reactive protein levels. Serum concentrations of Trp, KYN, and KYNA decreased, while 3-HK showed a non-significant upward trend. Enzymatic indexes revealed a significant increase in the 3-HK/KYN ratio and a decrease in the KYNA/3-HK ratio, suggesting a shift toward kynurenine monooxygenase (KMO) branch. Notably, higher KYNA-related ratios were inversely associated with depressive symptoms. Conclusions: These findings position the KP as a responsive metabolic interface potentially linking improvements in body composition, liver function, and psychological status during structured weight loss efforts.

Background/Objectives: Frailty has been associated with various physical, psychological, and social factors; however, the influence of the residential environment—particularly walk-up buildings without elevators—remains unclear. This study aimed to examine the association between the floor of residence and frailty among functionally independent older adults. Methods: A total of 793 older adults (mean age: 76.46 ± 6.29 years; 58.83% women) living in walk-up buildings without elevators and not certified as requiring long-term care participated in a questionnaire survey. Frailty was assessed using the Kihon Checklist (KCL) and the FRAIL Scale (FS). Logistic regression analyses were conducted to examine the association between floor of residence and frailty status (non-frail vs. frail), adjusting for potential confounders. Sensitivity analyses were performed using stratified models based on age group, functional status, and living conditions. Results: Frailty prevalence was 23.28% (KCL) and 16.88% (FS). Higher floor of residence was significantly associated with lower odds of frailty (KCL: odds ratio [OR] = 0.82, 95% confidence interval [CI]: 0.69–0.97; FS: OR = 0.80, 95% CI: 0.65–0.97). Stratified analyses showed consistent associations in subgroups including those aged ≥ 75 years, with full Instrumental Activities of Daily Living scores, non-homebound status, poor subjective economic status, and living alone (all p < 0.05). Conclusions: Living on higher floors in walk-up buildings without elevators may be protective against frailty among functionally independent older adults. While barrier-free environments are essential for those with functional decline or disabilities, moderate physical challenges such as stairs may contribute to frailty prevention in populations who maintain independence.
