UNASSIGNED: A decline in adolescent health holds significant repercussions for public health. Promoting exercise is essential to improve physical and mental health among youth. This study aimed to explore the effect of CrossFit training programs on the physical health and sociogenic somatic anxiety of adolescents.
UNASSIGNED: In March 2023, 100 adolescents were openly recruited from eight middle schools in Jinhua, China. The participants, were divided equally into control and experimental groups, experienced either traditional or CrossFit training, respectively, over nine weeks. Evaluation measures included the analysis of social physique anxiety, body esteem, physical self-efficacy, and general physical health before and after the exercise program.
UNASSIGNED: Post-intervention data demonstrated marked reductions across all facets of the social physique anxiety scale, including worries about public scrutiny, anxiety from social comparison, and discomfort related to one\'s physical self-image, more so in the experimental group (P<0.05). Likewise, assessments of the physical self-perception profile and physical self-efficacy scale were enhanced, again with the experimental cohort displaying more pronounced improvements (P<0.05). Results from biophysical function evaluations indicated significant health improvements post-intervention, with noted advancements in lung capacity, aerobic fitness by the standing long jump, and muscular endurance as assessed by grip strength, sit-up, and push-up counts, primarily in the experimental group (P<0.05).
UNASSIGNED: CrossFit training offered considerable advantages by reducing social physique anxiety and enhancing adolescents\' body esteem and physical self-efficacy. The program stimulated improvements in body composition, cardiorespiratory fitness, muscle strength, and flexibility.

Mobile application (app), with its expansive reservoir of data and content, harbors considerable promise in advancing health outcomes at both the individual and population levels. Nevertheless, there is a paucity of scholars that concretely examine the dynamics of health information acquisition within mobile app. This research presents a conceptual model aimed at investigating the potential ramifications of health information acquisition on both individuals\' psychological and physical well-being. Concurrently, this research attempts to illuminate the underlying mechanisms behind these correlations through evaluating the mediating role of bonding and bridging social capital. The obtained results of a web-based survey conducted among 656 college students in mainland China suggest a positive association between health information acquisition and bonding and bridging social capital. Moreover, the study reveals that the impact of health information acquisition via mobile applications on psychological and physical well-being is significantly mediated by college students\' bonding and bridging social capital. The cultivation of bonding social capital could exert a direct and positive influence on college students\' physical well-being. However, there appears to be no discernible correlation between bridging social capital and physical well-being. Taken collectively, these findings not only complement extant theoretical perspectives within the scholarship concerning mobile app usage for health improvement, but also furnish several pragmatic guidelines for healthcare professionals and mobile app designers.

An extensive literature has documented the deleterious effects of weight bias internalization (WBI) on biopsychosocial health outcomes. Still, this research is largely confined to the Western context. Furthermore, few studies have explored associations between WBI and biopsychosocial health outcomes, including in non-Western adolescent populations.
The present study explored the longitudinal relationships between WBI and body dissatisfaction, disordered eating, psychosocial impairment related to eating disorder features, and psychological and physical well-being in a sample (N = 1549; aged 11-18 years at baseline) of Chinese adolescents. Relationships between study variables were examined between two waves of data measurement (Time 1, baseline, and Time 2, 6-month). Cross-lagged and multivariate models were used to explore prospective relationships between WBI and biopsychosocial correlates.
Bidirectional relationships were observed between WBI and biopsychosocial correlates in Chinese adolescents. Adjusting for covariates and other predictor variables, higher body dissatisfaction, disordered eating, psychosocial impairment, and psychological distress at Time 1 predicted higher WBI at Time 2. Furthermore, higher WBI at Time 1 predicted higher body dissatisfaction, disordered eating, psychosocial impairment, and psychological distress at Time 2.
Weight bias internalization and psychosocial correlates were interrelated across time in Chinese adolescents. Improving WBI might be promising in the prevention of eating and body image disturbances and diminished psychosocial well-being. Similarly, reducing eating and body image disturbances and improving psychosocial well-being might be useful prevention targets in reducing WBI in Chinese adolescents.
The present study represents an initial effort to explore bidirectional relationships between WBI and biopsychosocial health outcomes in Chinese adolescents. Findings suggest bidirectional relationships between WBI and psychosocial variables, highlighting the potential utility of incorporating WBI interventions into eating pathology and poor psychosocial well-being prevention designs for Chinese adolescents.

The importance of age-friendly environments (AFEs) for older adults has been empirically and theoretically highlighted by the extant literature. However, the strength of the association between environments and older adults’ well-being has not been comprehensively quantified. Given the different attributes of the physical and mental dimensions, this meta-analysis aims to synthesise and quantify the association between AFEs and the physical and mental well-being of older adults. Fourteen eligible studies were included in this analysis: among which eight explored the link between AFEs and physical well-being, and eleven investigated AFEs in association with mental well-being. A random-effects model showed a small but significant correlation between AFEs and the mental well-being of older adults (r = 0.160, 95% CI [0.084, 0.224], p < 0.001), and the correlation between AFEs and physical well-being was also significant (r = 0.072, 95% CI [0.026, 0.118], p < 0.01). The number of environmental factors involved in AFEs moderated the association with physical well-being, from which the association was only significant among studies focusing on fewer environmental factors (n < 6). Results of this meta-analysis indicated that AFEs may be more effective in promoting the emotions of older adults, compared to ameliorating their physical functioning. The limitations of current empirical studies and directions for future research in the field of environmental gerontology were also discussed.

Chinese culture attaches great importance to the education and cultivation of youth conscientiousness, however in the context of Chinese culture, little is known about the relationship between conscientiousness and mental and physical health. The present study aimed to investigate whether there is a reciprocal relationship between conscientiousness and well-being (subjective and physical well-being) among Chinese undergraduate students. A series of self-reported questionnaires were administered to 365 undergraduate students in 2 waves, separated by 1 year. Cross-lagged regression analyses were applied to examine the reciprocal relationships. Results indicated that conscientiousness positively predicted subsequent levels of positive affect and life satisfaction, while negatively predicted subsequent levels of negative affect and physical symptoms, controlling for the effects of gender, age, body-mass index, socioeconomic status, and the prior level of conscientiousness. Whereas, positive and negative affect, life satisfaction, and physical symptoms did not significantly predict subsequent levels of conscientiousness. This study suggests that conscientiousness is a robust and prospective predictor of subjective and physical well-being. The reciprocal relationship between conscientiousness and well-being was not confirmed in the current sample of Chinese undergraduate students.

In Hong Kong, where the aging problem is inevitable, it is increasingly common for older adults to be admitted to day care centers. However, there has been limited research exploring conceivable indicators of healthy aging among older adults in such settings. The present study investigated the associations among the three indicators (physical competence, physical well-being, and perceived physical literacy) among older adults in day care centers of Hong Kong. A total of 97 participants (aged 60 years old or above) participated in the study from April to July 2021 amid the COVID-19 pandemic. Data on participants’ sociodemographic information, physical competence (PC), physical well-being (PWB), and perceived physical literacy (PPL) were collected. Our results showed that the level of PC reached a high level among the participants. Positive correlations were found between PC and PWB and between PPL and PWB (r = 0.22−0.23, p < 0.05). However, PC was not associated with PPL (r = 0.11, p > 0.05). In addition, as a component within PPL, “knowledge and understanding” (KU) was found to be correlated with PC (r = 0.21, p < 0.05) and had a positive and moderate correlation with PWB (r = 0.35, p < 0.01). The results suggest that older adults admitted to day care centers maintain and enhance their physical competence to improve their physical well-being. Greater knowledge and understanding of physical literacy and physical health should be delivered among day care centers considering future development.

COVID-19 has had considerable effects on people\'s lives worldwide, particularly left-behind children in China as they tragically witnessed the outbreak. From the outset, millions of left-behind children in rural areas experienced extensive physical and psychological disturbances because their migrant parents who lived in the city or another province could not be with them. This study explored the psychological, academic, and physical well-being of rural left-behind children during COVID-19. We captured the experiences of 10- to 15-year-old children and adolescents who were left behind by their migrant parents before the COVID-19 outbreak. The results of the present study suggest that left-behind children have exhibited severe psychological illnesses since the pandemic has limited their social interactions with peers and increased improper caretaking from grandparents.

BACKGROUND: The present study investigates the well-being effects for 10- to 12-year-old children  who participated in the school-based intervention \"11 for Health in Denmark,\" which comprises physical activity (PA) and health education. Subgroup analyses were carried out for boys and girls.
METHODS: Three thousand sixty-one children were randomly assigned to an intervention group (IG) or a control group (CG) by 5:1 cluster randomization by school. 2533 children (mean age 11.5 ± 0.4; 49.7% boys) were assigned to IG and 528 children (mean age 11.4 ± 0.5; 50.8% boys) were assigned to CG. IG participated in the \"11 for Health in Denmark\" 11-week program, consisting of 2 × 45 min per week of football drills, small-sided games, and health education. CG did not participate in any intervention and continued with their regular education. Before and after the intervention period, both groups answered a shortened version of the multidimensional well-being questionnaire KIDSCREEN-27.
RESULTS: The \"11 for Health in Denmark\" intervention program had a positive effect on physical well-being in girls (IG: 48.6 ± 8.5 to 50.2 ± 9.3), whereas the improvement was not significant in boys. The program also had a positive impact on well-being scores for peers and social support (IG: 50.2 ± 10.2 to 50.8 ± 10.1), though when analyzed separately in the subgroups of boys and girls the changes were not significant. No between-group differences were found for psychological well-being or school environment.
CONCLUSIONS: The intervention program had a positive between-group effect on physical well-being in girls, whereas the change was not significant in boys. The overall scores for peers and social support improved during the intervention period, but no subgroup differences were found.

Although the World Health Organization (WHO) has defined health as a state of physical, mental and social well-being, public health strategies have primarily focused on one domain of well-being. We sought to systematically and simultaneously identify and validate associations of behavioural patterns, psychosocial factors, mental and physical health conditions, access to and utilization of health care and anthropometrics with physical, mental and social well-being.
We conducted a longitudinal environment-wide association study (EWAS) with a training and testing set approach, accounting for multiple testing using a false discovery rate control. We used multivariate multilevel regression to examine the association of each exposure at wave 1 with the three outcomes at wave 2 in the Hong Kong FAMILY Cohort (n = 10 484).
Out of 194 exposures, we identified and validated 14, 5 and 5 exposures that were individually associated with physical, mental and social well-being, respectively. We discovered three factors, namely depressive symptoms, life satisfaction and happiness, that were simultaneously associated with the three domains that define health.
These associations, if verified to be causal, could become intervention targets to holistically improve population health. Our findings provide empirical support for placing mental health at the forefront of the public health agenda, and also support recent calls to use life satisfaction and happiness to guide public policy.
