Abstract
Importance Overweight and obesity affect 340 million adolescents worldwide and constitute a risk factor for poor mental health. Understanding the association between body mass index (BMI) and mental health in adolescents may help to address rising mental health issues; however, existing studies lack comprehensive evaluations spanning diverse countries and periods. Objective To estimate the association between BMI and mental health and examine changes over time from 2002 to 2018. Design, Setting, and Participants This was a repeated multicountry cross-sectional study conducted between 2002 and 2018 and utilizing data from the Health Behaviour in School-aged Children (HBSC) survey in Europe and North America. The study population consisted of more than 1 million adolescents aged 11 to 15 years, with all surveyed children included in the analysis. Data were analyzed from October 2022 to March 2023. Main Outcomes and Measures Mental health difficulties were measured by an 8-item scale for psychological concerns, scoring from 0 to 32, where a higher score reflects greater psychosomatic issues. BMI was calculated using weight divided by height squared and adjusted for age and sex. Data were fitted by multilevel generalized additive model. Confounders included sex, living with parents, sibling presence, academic pressure, the experience of being bullied, family affluence, screen time, and physical activity. Results Our analysis of 1 036 869 adolescents surveyed from 2002 to 2018, with a mean (SD) age of 13.55 (1.64) years and comprising 527 585 girls (50.9%), revealed a consistent U-shaped association between BMI and mental health. After accounting for confounders, adolescents with low body mass and overweight or obesity had increased psychosomatic symptoms compared to those with healthy weight (unstandardized β, 0.14; 95% CI, 0.08 to 0.19; unstandardized β, 0.27; 95% CI, 0.24 to 0.30; and unstandardized β, 0.62; 95% CI, 0.56 to 0.67, respectively), while adolescents with underweight had fewer symptoms (unstandardized β, -0.18; 95% CI, -0.22 to -0.15). This association was observed across different years, sex, and grade, indicating a broad relevance to adolescent mental health. Compared to 2002, psychosomatic concerns increased significantly in 2006 (unstandardized β, 0.19; 95% CI, 0.11 to 0.26), 2010 (unstandardized β, 0.14; 95% CI, 0.07 to 0.22), 2014 (unstandardized β, 0.48; 95% CI, 0.40 to 0.56), and 2018 (unstandardized β, 0.82; 95% CI, 0.74 to 0.89). Girls reported significantly higher psychosomatic concerns than boys (unstandardized β, 2.27; 95% CI, 2.25 to 2.30). Compared to primary school, psychosomatic concerns rose significantly in middle school (unstandardized β, 1.15; 95% CI, 1.12 to 1.18) and in high school (unstandardized β, 2.12; 95% CI, 2.09 to 2.15). Conclusions and Relevance Our study revealed a U-shaped association between adolescent BMI and mental health, which was consistent across sex and grades and became stronger over time. These insights emphasize the need for targeted interventions addressing body image and mental health, and call for further research into underlying mechanisms.

Abstract
PURPOSE While the individual impacts of long-term residence and food insecurity on overweight/obesity are well-documented, their combined effect on immigrants' weight status is less understood. This study examines the interaction between length of residence and food insecurity in predicting overweight/obesity among immigrants and investigates whether this relationship is gender-specific. DESIGN A national cross-sectional survey. SETTING The 2017-2018 Canadian Community Health Survey. SUBJECTS Immigrants aged 18 and older (N = 13 680). MEASURES All focal variables were self-reported. ANALYSIS Logistic regression models were employed. RESULTS Long-term immigrants were more likely to report overweight/obesity than their short-term counterparts (OR = 1.39; P < .001). Moreover, immigrants from food-insecure households were at a higher risk of reporting overweight/obesity (OR = 1.27; P < .05) compared to those from food-secure households. The analysis further revealed that food insecurity exacerbated the detrimental association between length of residence and overweight/obesity in men (OR = 2.63; P < .01) but not in women (OR = .66; P > .05). CONCLUSION The findings suggest that long-term immigrant men may be especially susceptible to the compounded chronic stressors of extended residence and food insecurity. Health professionals and policymakers should advocate for psychosocial resources to help mitigate these adverse effects and support the well-being of immigrant populations.

Chai L. Interplay between actual and perceived weight on mental health among Canadian Indigenous post-secondary students. JOURNAL OF AMERICAN COLLEGE HEALTH : J OF ACH 2024:1-9. [PMID: 38592936 DOI: 10.1080/07448481.2024.2338419] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 03/22/2024] [Indexed: 04/11/2024]
Abstract
OBJECTIVES Research increasingly focuses on the mental health implications of both actual and perceived weight, particularly among post-secondary students. Considering their unique socio-cultural context and the frequent oversight in research, this study examines these implications specifically among Canadian Indigenous post-secondary students. Recent evidence indicates that students with normal weight may also experience increased mental health risks due to negative weight perceptions. Therefore, this study explores the independent and combined effects of actual and perceived weight on the mental health of this group. PARTICIPANTS AND METHODS This study utilized data from the 2017 Aboriginal Peoples Survey, a nationally representative sample of First Nations peoples living off-reserve, Métis, and Inuit. The focus was on Canadian Indigenous post-secondary students aged 19-34 years (n = 1,518). Logistic regression models, stratified by sex, were employed to analyze the data. RESULTS Perceptions of being overweight were linked to a higher risk of mood and anxiety disorders, poor self-rated mental health, and suicidal ideation among female students. This pattern was less evident among male students. Notably, female students who were overweight and perceived themselves as such were more likely to report poor mental health across all four indicators examined. In contrast, male students exhibited a less clear pattern. Diverging from recent studies, the findings indicated less robust mental health disparities among students with normal weight who perceived themselves as overweight, potentially due to the insufficient cell size of this category among Indigenous post-secondary students. CONCLUSIONS The study highlights the complex interplay between actual and perceived weight and its impact on mental health, particularly among female Indigenous post-secondary students.

Abstract
As the population ages, the global burden of cardiometabolic disorders will increase. This study aimed to investigate the prevalence of cardiometabolic disorders (diabetes, hypertension, and hyperlipidemia) in elderly and to evaluate the effects of various variables including age, sex, education, marital status, smoking, income, physical activity, dementia and depressed mood on untreated cardiometabolic disorders. This was a cross sectional study conducted in Bushehr Elderly Health Program. A total 2381 participants were included. Medical data were collected by trained interviewers. The mean age of the study participants was 69.34 years. Proportions of diabetes, hypertension, hyperlipidemia and hypercholesterolemia were 43.25%, 75.71%, 64.74% and 35.31% respectively. Untreated diabetes prevalence was higher for males (OR = 1.60, 95%CI = 1.20-2.15), older adults (OR = 1.02, 95%CI = 1.00-1.05), and pre-frail status (OR = 0.69, 95%CI = 0.52-0.92). Males (OR = 2.16, 95%CI = 1.64-2.84) and current smokers (OR = 1.42, 95%CI = 1.05-1.93), in contrast to married participants (OR = 0.25, 95%CI = 0.08-0.78), people with higher education levels (OR = 0.51, 95%CI = 0.29-0.89) and dementia (OR = 0.78, 95%CI = 0.61-1.00) were more likely to have untreated HTN. Untreated dyslipidemia is more common in smokers (OR = 1.78, 95%CI = 1.19-2.66) and males (OR = 1.66, 95%CI = 1.21-2.27), while untreated hypercholesteremia is more common in males (OR = 3.20, 95%CI = 1.53-6.69) and is reported lower in people with dementia (OR = 0.53, 95%CI = 0.28-1.01).

Abstract
PURPOSE This study examines the moderating role of perceived community belonging in the association between sexual orientation and various health and well-being outcomes. DESIGN A national cross-sectional survey. SETTING Confidential microdata from the 2021 Canadian Community Health Survey. SUBJECTS Individuals aged 15 and older, with a sample size ranging from 43,000 to 44,100. MEASURES Sexual orientation, health and well-being outcomes, and sense of community belonging were all self-reported. Outcomes included self-rated general and mental health, depressive symptoms, and life satisfaction. ANALYSIS A series of multiple linear regression models. RESULTS Compared to heterosexual individuals, bisexual individuals reported poorer self-rated general health (b = .402, P < .001 for men; b = .454, P < .001 for women) and mental health (b = .520, P < .001 for men; b = .643, P < .001 for women), higher depressive symptoms (b = 2.140, P < .001 for men; b = 2.685, P < .001 for women), and lower life satisfaction (b = .383, P < .05 for men; b = .842, P < .001 for women). Few disparities were observed among gay men and lesbians. Contrary to some recent findings, no disparities were observed among individuals uncertain about their sexual orientation or those who chose not to disclose it, even without controlling for covariates. A stronger sense of community belonging mitigated the disadvantages associated with self-rated general health (b = -.276, P < .01) and depressive symptoms (b = -.983, P < .01) for gay men, and life satisfaction (b = -.621, P < .01) for lesbians. CONCLUSION This study is among the first to highlight the stress-buffering role of community belonging in the association between sexual orientation and health and well-being outcomes.

Abstract
Existing research has established the detrimental effects of food insecurity on health. However, understanding of the social conditions that may moderate this relationship remains limited. To address this gap, the study investigates two questions: First, does marital status moderate the association between food insecurity and self-rated health? Second, if such moderation exists, does its impact vary based on gender? Data from the 2017-2018 Canadian Community Health Survey, a nationally representative survey conducted by Statistics Canada (n =101 647), were utilized for this investigation. The findings demonstrated that individuals living in food-insecure households reported poorer self-rated mental and general health. However, the negative impact of food insecurity on both health outcomes was less pronounced among married individuals than among their unmarried counterparts. Furthermore, the stress-buffering role of marriage was found to be more substantial among men than among women. In light of the significant stress-buffering role of marriage revealed in this study, it is crucial for policies to aim at providing comparable coping resources to unmarried individuals, particularly women.

Abstract
This study explored the relationship between adolescents’ weight status and mental health problems. It specifically investigated the weight perceptions of obese adolescents and the effect on their mental health. This cross-sectional study was based on the data of adolescents aged 12–18 years from the Korean National Health and Nutritional Examination Survey (2010–2019). Data regarding anthropometric measurements, health conditions, and socioeconomic status were extracted, and the associations between weight status (actual, perceived, or misperceived) and mental health conditions (depressed mood, perceived stress, and suicidal ideation) were analyzed using complex sample multiple logistic regression after adjusting for possible confounders. A total of 5683 adolescents (53.1% boys and 46.9% girls) were included in this study, with a mean age of 15.1 years. Among the participants, actual, perceived, and misperceived status of being overweight were observed in 20.8%, 32.7%, and 18.4%, respectively. Additionally, depressed mood, perceived stress, and suicidal ideation were observed in 9.1%, 25.7%, and 7.4% of Korean adolescents, respectively, with higher prevalences in girls for all three conditions. Actual weight status was not significantly associated with mental health conditions in either sex. Furthermore, girls who perceived themselves to be overweight, regardless of their actual body weight, or who had overestimated their actual weight were more likely to have experienced depressed mood and stress, while boys who perceived themselves to be underweight were more likely to have experienced suicidal ideation than participants with an average weight perception or an accurate recognition of their weight status. Conversely, in overweight/obese participants, perceived weight status was not associated with mental health conditions. In conclusion, perceived weight status and its discrepancy with actual body weight were more strongly associated with an increased risk of mental health problems than actual weight status itself among Korean adolescents. Therefore, adolescents’ perceptions of their body image and weight-related attitude should be assessed to promote their mental health.

Abstract
The present study examines (1) whether perceived life stress mediates the associations between length of residence in Canada and self-rated mental health and general health and (2) how these processes differ across levels of perceived local community belonging. Data are from the 2017-2018 Canadian Community Health Survey (N = 14,570)-a nationally representative survey collected by Statistics Canada. Simple mediation and moderated mediation models are employed. The simple mediated associations are evaluated first and found to be statistically significant for both self-rated mental health (b = 0.046, 95% PBCI = 0.035, 0.058) and general health (b = 0.045, 95% PBCI = 0.034, 0.056). Moderated mediation analysis then reveals that while perceived local community belonging does not moderate the effects of length of residence on perceived life stress, it does moderate the effects of perceived life stress on self-rated mental health (b = - 0.042, 95% PBCI = - 0.057, - 0.028) and general health (b = - 0.026, 95% PBCI = - 0.042, - 0.011), suggesting that the adverse associations between perceived life stress and self-rated mental health and general health are weaker among immigrants with greater perceived local community belonging. Consistent with the predictions, the indirect effects are significant at all levels of local community belonging. Findings from this study highlight the need to focus more research and policy interventions on community-based coping resources.

Abstract
While prior research has well-documented the detrimental effect of cyberbullying victimization on health and well-being among children and adolescents, less is known about whether the same adverse pattern can be observed among adults. Moreover, it is unclear about what psychosocial resources might moderate this association. The present study uses a nationally representative cross-sectional survey-2014 Canadian General Social Survey (N = 17,548)-to examine three research questions. First, is cyberbullying victimization associated with adults' self-rated health, mental health, and life satisfaction? Second, how does religiosity-religious service attendance and religious beliefs-moderate this association? Third, do any observed patterns further differ for men and women? Through a series of logistic and ordinary least squares regression models, the results show that adults who experienced cyberbullying victimization in the past 5 years are more likely to report poor self-rated health and mental health compared to those who did not experience cyberbullying victimization in the past 5 years. Likewise, cyberbullying victimization is also associated with lower levels of life satisfaction. In addition, the adverse associations of cyberbullying victimization in the past 5 years with self-rated health and life satisfaction are weaker among those who attended religious service at least once a week in the past twelve months. A similar pattern is observed for the buffering effect of viewing religious beliefs as very important in the adverse association of cyberbullying victimization in the past 5 years with self-rated life satisfaction. There is also evidence suggesting the gendered buffering effect of the importance of religious beliefs in the association between cyberbullying victimization and self-rated health. This study makes important empirical and theoretical contributions to the growing field of research on the association between cyberbullying victimization and health and well-being and to our understanding of how religion matters to individuals dealing with stressful experiences.

Psychosocial Predictors of Body Weight Congruence in Adolescents Aged 15 and 17 Years in Poland: Findings from the Health Behaviour in School-Aged Children (HBSC) Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19042342. [PMID: 35206529 PMCID: PMC8872581 DOI: 10.3390/ijerph19042342] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 02/16/2022] [Accepted: 02/17/2022] [Indexed: 01/25/2023]
Abstract
Background: Body weight congruence (BWC) has implications for adolescent health. The main goal of this study was to examine the distribution of BWC and its relationship with six psychosocial factors. Methods: A representative sample of N = 3508 adolescents aged 15 and 17 years (52.4% girls) derived from the Health Behaviour in School-aged Children study, conducted in 2017/2018 in Poland, was used. BWC groups were defined based on self-reported BMI and subjective assessment of weight: (1) correct perception; (2) overestimation, and (3). underestimation. Principal component analysis (PCA) extracted the following two factors: a socio-relational factor (SR) related to perceived social support and social self-efficacy, and a body attitudes and social media exposure factor (BAME). Using the total sample, multinomial logistic regression was applied to estimate their impact on the BWC, and gender-specific models were compared. Results: Half (48.6%) of the adolescents correctly estimated their body weight, 31.0% overestimated it (girls 43.9%, boys 17.1%), and 20.0% underestimated it (boys 37.2%, girls 9.0%). Overestimation of body weight concerns 48.0% of normal weight girls, 50.0% of underweight girls, and 21.3% and 32.1% of normal weight and underweight boys, respectively. The percentage of normal weight (34.4%), and overweight and obese (30.8%) boys who underestimated their body weight was three times higher than the respective percentages of girls that underestimated their weight (9.0% and 11.9%). The SR factor protected adolescents from both underestimation (only in girls) and overestimation in the total sample (OR 0.74, 95%CI 0.68–0.81) and both genders. BAME increased this risk of overestimation in both genders (OR = 1.83, 95%CI 1.67–2.0), and the risk of underestimation among boys. Conclusions: Prevention programmes should include a wide range of psychosocial factors to improve BWC among adolescents.
