Urbanization is a multifaceted process that can have both positive and negative effects on mental health, especially in adolescents. This paper attempts to summarize the impact of urbanization on youth mental health in Hong Kong.

Millions of people in Indonesia have diabetes. The cluster of metabolic abnormalities has long been identified as the risk factors for type 2 diabetes and is now commonly described as metabolic syndrome/MetS. Insulin resistance takes a key role in the process of the MetS and has even been hypothesized as its underlying cause. Clinical and epidemiologic studies also indicate that inflammatory factors might be correlated with IR. Prospective studies have proved that metabolic syndrome grows during childhood/adolescence and progresses to adulthood T2DM. The purpose of this study was to investigate relationships between metabolic syndrome components and low-grade systemic inflammation with insulin resistance in non-diabetic Indonesian adolescent male.This was a cross-sectional analysis of non-diabetic adolescent male in Indonesian population (n = 128) aged between 18 and 22 years old. MetS components are based on NCEP ATP III (2004) modification for Asia Pacific population. Marker for low-grade systemic inflammation is hsCRP and insulin resistance was determined by HOMA-IR formula. Relevant measures were anthropometry, blood pressure, fasting insulin, serum glucose, lipid profiles and hsCRP.Of the 128 adolescent male, we found that 16 subjects (12.5%) have central obesity; 3 subjects (2.3%) have hyperglycemia; 26 subjects (20.3%) have low HDL-c; 19 subjects (14.8%) have high triacylglycerol; 45 subjects (35.2%) have hsCRP ≥1.0 mg/dL; 4 subjects (3.1%) have high blood pressure and 39 subjects (30.5%) have insulin resistance. The association of MetS components with the risk of insulin resistance is central obesity and high triacylglycerol with OR of 24.4 (95%CI: 5.19-114.42) and 9.4 (95%CI: 3.09-28.68) consecutively. We also found that low-grade systemic inflammation (hsCRP ≥1.0 mg/dL) was strongly associated with incident of insulin resistance with OR 5.2 (95%CI: 2.31-11.64). Meanwhile, we found that high triacylglycerol level is the solely one of five MetS components which has contribution to the incident of systemic low-grade inflammation with OR 3.9 (95%CI: 1.43-10.92).Central obesity and high triacylglycerol level are the important MetS components associated with IR. Systemic low-grade inflammation has been associated with insulin resistance. Identification of obesity, high triacylglycerol and high hsCRP should be focused for prevention of type 2 diabetes in non-diabetic Indonesian adolescent male.Copyright © 2019 The Authors.

Background: This study examined the compliance with the 24-Hour Movement Guidelines among Hong Kong adolescents and its associations with body mass index (BMI). Methods: A total of 1039 adolescents (11–18 y) wore the activPAL™ for 24 hours for 7 consecutive days to assess physical activity (PA) and sleep duration. Screen time was measured using the Children’s Leisure Activities Study Survey (Chinese version). Linear mixed models were performed for analysis. Results: The analytic sample consisted of 692 adolescents (53% girls). Only 1.0% of the adolescents met all of the recommendations. The proportions of adolescents who met the recommendation for PA, screen time, and sleep were 9.1%, 31.2%, and 38.6%, respectively. Adolescent boys who did not meet the PA recommendation (β = 3.36; 95% CI, 1.04 to 5.68; P = .001) and those who did not meet the combination of PA and sleep recommendations (β = 2.10, 95% CI, 0.64 to 3.56; P = .01) had a higher body mass index than those who met the respective recommendations. Conclusions: Compliance with the 24-Hour Movement Guidelines was alarmingly low among Hong Kong adolescents. Meeting the PA recommendation or the combination of PA and sleep recommendations was associated with a healthier body weight in boys.

Motivational processes and emotional self-regulation are relevant factors for predicting the practice of physical exercise and for certain health-related parameters. The aim of the present work, developed along two different phases, was, on the one hand, to determine the prevalence of physical inactivity and, on the other hand, to carry out a comparative analysis between physically active and inactive university students in relation to their motivational determinants, emotional self-regulation, physical condition, health-related quality of life and other health parameters. The results obtained showed a prevalence of physical inactivity of 12.78%. Physically inactive participants showed significantly lower scores in intrinsic motivation, emotion regulation, and in some dimensions of health-related quality of life, as well as significantly high levels of body fat mass. Lastly, logistic regression analysis identified low scores in Emotional Clarity (p=.009) and Identified Regulation (p = .011), and high scores in Amotivation (p = .006) as reliable predictors of a physically inactive lifestyle. These results are useful for the design and implementation of programs aimed at promoting health and physical activity, with special attention on physically inactive youth populations.

The purpose of this study is to understand the potential types of anxiety among middle school students by analyzing the current situation of middle school students’ anxiety and its influencing factor. This study used a multistage stratified cluster random sampling to investigate students in grades 9 to 12. Mplus 7.4 was used for latent profile analysis. A total of 900 junior high school students were investigated. The junior high school students were divided into three subgroups by latent profile analysis. A total of 223 junior high school students experienced severe anxiety, accounting for 24.78%. Multivariate logistic regression analysis revealed that males are more likely to develop moderate and severe anxiety. The development of severe anxiety (OR = 0.562, p < 0.05) is less likely for students in schools with adequate mental health support. Students who were confident with their academic performances were less likely to develop moderate anxiety (OR = 0.377, p < 0.05). Students with extreme academic pressure are more likely to develop moderate anxiety (OR = 6.523, p < 0.05) and severe anxiety (OR = 11.579, p < 0.05). It is recommended that mental health counseling be set up in schools and to provide professional counselors to prevent serious anxiety for students. This paper also demonstrates a need to reduce students’ academic pressure.

Depressive symptoms are a common mental health problem among adolescents, which may affect their physical and mental health development and impose heavy burdens on individual families and society. This study aimed to examine the associations between sleep duration, academic pressure, and depressive symptoms among Chinese adolescents and to construct the mediation model to explore the mediating effect of sleep duration. The data are from the China Family Panel Studies (CFPS). Methodologically, the aforementioned associations were explored by constructing a structural equation model and applying multivariate multilevel logistic regression. In this study, we found that approximately 6.49% of the 3724 Chinese adolescents had depressive symptoms. Sleep duration of <6 h/night (OR = 2.39, 95%CI = 1.33–4.32) and high/maximum academic pressure (high: OR = 1.43, 95%CI = 1.02–1.99; maximum: OR = 2.43, 95%CI = 1.58–3.73) were both associated with an increased risk of depressive symptoms in adolescents. Meanwhile, the multiplicative interaction between sleep duration and academic pressure was significantly associated with depressive symptoms in adolescents (p < 0.001). The sleep duration played a partial mediating role in the relationship between academic pressure and depressive symptoms (a*b = 0.006, 95%BootCI = 0.001–0.012). Our study highlights that it is essential to mitigate the academic pressure of adolescents to increase their sleep duration and further reduce the occurrence of depressive symptoms by adopting corresponding preventive measures.

Internal migrants are exposed to higher risks of depressive symptoms due to migration-related stress. It has been recognized that perceived neighborhood social cohesion has direct and indirect associations with depressive symptoms. However, the pathway from perceived social cohesion to internal migrants' depressive symptoms was less discussed.

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.

Most US children and adolescents do not meet recommended daily physical activity (PA) guidelines. Determinants of PA are complex; however, access to opportunities precedes actual PA engagement. Schools are well positioned to support student PA through the provision of physical education (PE) and before, during, and after school PA opportunities through comprehensive (ie, expanded) school PA programming. Monitoring access to school PE and PA opportunities is an essential function of public health. However, there are limited comprehensive data across K-12 settings. Therefore, the purpose of this study was to evaluate students' access to PE and expanded recreation time before, during, and after school PA opportunities in K-12 schools across 25 US states.The US Physical Education and Physical Activity Policy questionnaire was completed by 4845 K-12 PE teachers across 25 states, representing diverse geographical regions, with responses standardized across varying academic calendars. Descriptive statistics were used to illustrate access to PE and PA opportunities.Access to PE and PA varied, with elementary schools generally providing more opportunities than middle and high schools. There was an overall misalignment with national PE and recess recommendations. Limited before and after school PA opportunities were also reported.The relative dearth of access to PE and expanded PA opportunities currently available to students in relation to national guidelines shows a need for states to prioritize expanding access to PE and recreational PA to reduce disparities. To ensure more equitable student access, collaborative efforts among educators, policymakers, and stakeholders are essential.

Mental health in children and adolescents has become an increasingly important topic in recent years. It is against this backdrop that physical education and school sports play an important role in promoting psychological wellbeing. The aim of this review was to analyse interventions for improving psychological wellbeing in this area. To this end, a literature review was conducted using four databases (WOS, SPORTDiscus, SCOPUS and ERIC) and the following keywords: psychological wellbeing, physical education, and school sports. Twenty-one articles met the inclusion criteria. The results showed that interventions varied greatly in terms of duration and used a wide range of strategies (conventional and non-conventional sports, physical activity, games, etc.) for promoting psychological wellbeing, primarily among secondary school students. There was a lack of consensus as to the conceptualisation of the construct of psychological wellbeing, resulting in a variety of tools and methods for assessing it. Some studies also suggested a link between psychological wellbeing and other variables, such as basic psychological needs and self-determination. Finally, this study provides a definition of psychological wellbeing through physical activity based on our findings.

The Parent Behavior Change Intervention (PBC-I) was developed to target parent-adolescent conversations that promote adolescent health behavior change. We report on an open trial of the PBC-I. Participants were 36 parent-adolescent dyads. Adolescents received the Transdiagnostic Sleep and Circadian Intervention (TranS-C) as parents received the PBC-I. Dyads were assessed at pre- and postintervention for parent use of behavior change techniques (BCT) and positive and negative conversational behaviors, parent-adolescent conflict, adolescent motivation for change, and adolescent sleep outcomes. From pre to post, parents used fewer total and types of BCTs, more positive communication behaviors, and less negative communication behaviors when discussing a sleep-related hot topic. From pre to post, parents reported decreased coercion and less anger intensity, while adolescents reported fewer parental conflict behaviors and less quantity and anger intensity during parent-adolescent disagreement. There was a pre-to-post increase in interest/enjoyment of sleep and a decrease in effort/importance to participate in TranS-C. More positive and less negative communication was associated with select adolescent sleep outcomes. Parents rated the PBC-I as highly acceptable and perceived it as useful. These results provide preliminary evidence that supports the PBC-I in improving the parent-adolescent interpersonal process, which is linked to improved adolescent sleep. The results may be relevant to conversations parents have with adolescents about a range of health behavior changes.Copyright © 2024. Published by Elsevier Ltd.
