Abstract
This study aimed to evaluate the effects of the COVID-19 pandemic on obesity, metabolic parameters, and clinical values in the South Korean population. Data from the seventh and eighth National Health and Nutrition Examination Surveys were analyzed, comprising 3560 participants in 2018 (pre-COVID-19) and 3309 participants in 2021 (post-COVID-19). The study focused on adults aged 19 years and older who were overweight (BMI ≥ 25 kg/m2). The results showed a significant increase in waist circumference (approximately 2 cm), BMI (approximately 0.11 kg/m2), systolic blood pressure, fasting blood sugar (1.76 mg/dL higher), and glycated hemoglobin (0.14% higher) in the post-COVID-19 group compared to the pre-COVID-19 group. Additionally, the prevalence of hypercholesterolemia increased by 4% after the COVID-19 pandemic. These findings suggest an increased risk of obesity, abdominal obesity, and metabolic disorders, such as blood sugar disorders, in the post-COVID-19 period. Urine analysis revealed abnormal findings, including occult blood, urobilinogen, hematuria, proteinuria, ketone urea, glycosuria, and bacteriuria. The study highlights the negative impact of lifestyle changes, such as reduced physical activity and social gatherings, on physical vital signs and clinical values during the COVID-19 pandemic.

Abstract
Studies have shown that adolescents now have a higher exposure to health risks than those in the past, and Hong Kong adolescents are no exception, particularly with the social crisis in 2019 and then the COVID-19 pandemic in 2020. Data from health care services for children and adolescents only represent the tip of the clinical iceberg, and health profiles, including living habits, lifestyles, data on health status, and health service utilization, are not always readily available for effective planning to cultivate a healthy living environment. In this paper, an exploratory study on secondary school students was conducted in one district of Hong Kong that has the potential and resources to become a healthy city. Students were found to have a high prevalence of poor sleep quality and quantity; excess screen time; physical inactivity; an insufficient intake of healthy food; emotional disturbance, including symptoms of post-traumatic stress disorders (PTSDs); and irregular attendance to student health services. A multivariate analysis showed that excessive time on social media websites, short sleeping hours, symptoms of PTSD, and a lack of regular exercise were independently associated with emotional distress. Youth service providers should re-orientate student health services, moving away from routine services to be more outreaching in order to cultivate a supportive living and learning environment, promoting better health for adolescents.

Abstract
COVID-19 has an impact on the day-to-day life of students, with school closure and detrimental effects on health and well-being that cannot be underestimated. A study collected data reflecting the health and well-being of secondary school students entering a programme entitled "Healthy Life Planning: Assist Students to Acquire and Practice Health Knowledge and Skills" (ASAP study) in September and October 2019 before the outbreak of COVID-19. Follow-up data were collected in June and July 2020, over half a year since the spread of COVID-19, which facilitated analyses of its impact on the health behaviours and well-being of young people. Comparative analyses between baseline and the follow-up period were conducted on weight status, sleep pattern and quality, pattern of sedentary lifestyle, pattern of physical activity, attitudes and perceived barriers for exercise, and hand hygiene. Attitudes toward precautionary measures and influenza vaccination, self-reported changes in hygiene practices, exercise habits and eating habits were analysed. Although hygiene habits and risk perceptions among young people have improved in many aspects, the level of physical activity has declined as well as the beliefs and attitudes on increasing time on electronic media and change in sleep hygiene. Attitudes and beliefs towards influenza vaccination have declined, which would reflect the slow increase in the uptake rate of COVID-19 vaccination. Health education should equip students with the knowledge and skills to cultivate beliefs and attitudes to face health challenges.

Zhu D, Sze NN. Propensities of red light running of pedestrians at the two-stage crossings with split pedestrian signal phases. ACCIDENT; ANALYSIS AND PREVENTION 2021; 151:105958. [PMID: 33385960 DOI: 10.1016/j.aap.2020.105958] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Revised: 12/02/2020] [Accepted: 12/14/2020] [Indexed: 06/12/2023]
Abstract
Two-stage crossing with a median refuge island is commonly installed at the busy urban signalized intersections. To accommodate for the high traffic flow in different directions, split phasing is often applied for pedestrians' right of way of the two crossing stages. Previous studies mainly focus on the time delay, capacity and operation efficiency of two-stage crossings. It is rare that safety of two-stage crossings is investigated. Crossing behaviors and propensities of red light running at the two crossing stages (i.e. from the curbside to a central island, and then to another side of the road) are different from that of single stage crossing. Also, there could be interferences in the crossing behaviors and situational features between the two stages. This study aims to identify the personal characteristics, traffic attributes and environmental factors that affect the red light running propensities of pedestrians at the two-stage crossings, based on the video observation surveys at six urban signal intersections in Hong Kong. Random parameter logit regression approach is applied to measure the association between possible factors and propensities of red light running of pedestrians, with which the effect of unobserved heterogeneity is accounted. Results indicate that, other than the pedestrians' characteristics, pedestrian signal of the second stage, maximum waiting time and traffic flow significantly affect the propensity of red light running in the first stage. Also, there are significant interaction effects between pedestrians' characteristics and situational features on the propensity. On the other hand, pedestrians' waiting time before crossing the first stage significantly affects the propensity of red light running in the second stage. Findings are indicative to the design of pedestrian crossing, signal time plan and effective enforcement and education strategies that can deter against the red light running behaviors of pedestrians. Therefore, safety of two-stage signalized crossings can be enhanced.

Abstract
Background Young people are challenged with sexual and reproductive health (SRH) problems due to limited access to services and information. It contributes a high burden of sexually transmitted disease, unsafe abortion, and premature mortality, especially in low-income countries like Ethiopia. Hence, this study aimed at assessing the SRH service utilization and associated factors among college students at West Arsi Zone in Oromia region, Ethiopia. Methods Institutional-based cross-sectional study was conducted among 519 randomly selected college students from January 01, 2019, up to April 30, 2019. Data were collected through self-administered pretested questionnaires. Data entry and analysis for descriptive and logistic regression models were performed by using SPSS (version 23). The result was declared as statistically significant at p < 0.05. Results The utilization of at least one SRH service in the last twelve months was seen in 304 (58.6%) students. Mainly information and counseling (81.3%), voluntary testing and counseling for HIV (80.6%), condom service (37.2%), pregnancy test (35.5%), family planning services (33.2%), and abortion care services (26.0%) were most frequently utilized. The students' aged between 20 and 24 years [AOR = 2.05, 95% CI: 1.38–3.06], female students [AOR = 1.92, 95% CI: 1.30–2.82], those not living with family [AOR = 1.54, 95% CI: 1.05–2.26], those who discussed about SRH with family/friends [AOR = 1.92, 95% CI: 1.31–2.82], and those who participated in school clubs [AOR = 1.75, 95% CI: 1.19, 2.58] more frequently used SRH service compared with their counterparts. Conclusions The utilization of SRH services was low when compared with other studies and needs improvements to tackle RH-related problems. It requires pertinent health education and the SRH club at higher educational institutions is crucial.

Abstract
OBJECTIVE Given the increasing burden of childhood obesity, it is important to examine the changes in dietary habits and prevalence of cardiovascular risk factors among Macao students. METHODS A cross-sectional study was conducted among primary and secondary school students in Macao, China in 2014-2015 with addition to data collected from 2008 to 2009 for comparison. The dietary behaviours, prevalence of obesity and dyslipidaemia were compared by study period. SUBJECTS In 2014-2015, dietary assessment was conducted among 3635 students, physical assessment was conducted among 1427 school students. In 2008-2009, dietary assessment was conducted among 4271 students, physical assessment was conducted among 1700 school students. RESULTS When compared with students in 2008, higher percentage of students from present study period consumed dairy products, crispy food and chocolate, while fewer students had fruits, vegetables and fried food at least once every day. Despite lower prevalence of elevated total cholesterol and low-density-lipoprotein cholesterol, the rate of general obesity, low high-density-lipoprotein cholesterol and hyperglycaemia has increased significantly in 2014-2015. Students aged 12-14 consumed less fruits and vegetables and suffered from higher rate of general and abdominal obesity, as well as low high-density-lipoprotein cholesterol and elevated serum triglycerides in 2014-15. CONCLUSIONS The students' diet had both favourable and unfavourable changes. The rate of obesity and dyslipidaemia rises, while the situation for students aged 12-14 is more concerning.

Abstract
BACKGROUND Improvement of health literacy, health behavioural change, creating a supportive physical and social environment to be more conducive to health should be the focus of child and adolescent public health. The concept of Health Promoting School initiated by World Health Organization aims to move beyond individual behavioural change and to consider organisational structure change such as improvement of the school's physical and social environment. The aim of this study is identification of the key indicators for successful implementation of Health Promoting School by analysing the findings of the school health profile based on the structured framework of Hong Kong Healthy School Award Scheme and the health status of students investigated by the Hong Kong Student Health Survey. METHODS This is a retrospective correlation study. Analysis of variance (ANOVA) was utilised to analyse for significant improvement of school health profile measured at baseline (n = 104) and among those schools implemented the Hong Kong Healthy School Award Scheme (n = 54). Those indicators showing statistical significance were chosen to be part of the core indicators reflecting effective Health Promoting School. Each of those selected core indicators was then correlated with the related student health outcomes measured by the Hong Kong Student Health Survey Questionnaire to further identify the core indicators. RESULTS A total of 20 core indicators among all the six Key Areas of Health Promoting School (6 indicators under action competencies, 2 under community link, 2 under physical environment, 2 under social environment, 4 under healthy school policies, 1 under services of school health protection) have been identified with the method mentioned above. CONCLUSIONS This study has identified the indicators with most significant impact on a wide range of health related outcomes. Those are key indicators for motivating positive change of the schools and students. They can be considered as school performance indicators to help schools embarking their Health Promoting School journey as another key education objective.

Abstract
Although Hong Kong is considered to be a relatively westernized Chinese society, sex remains to be a subject that is rarely discussed openly. This article provided a brief overview on the prevalence of sexual behaviors and attitudes among adolescents in Hong Kong. Compared with the West, Hong Kong adolescents are less sexually active; however, increasing rates and more liberal sexual attitudes have been reported over the decades. These worrying trends have caused great concern and begged the question of occurrences and the effectiveness of sex education programs. Endeavor has been made to identify protective factors for reducing adolescent risky sexual behaviors and promoting sexual health from a strength-based perspective, such as the positive youth development (PYD) approach. However, to date, there is little synthesis of empirical evidence in the literature on the relations between PYD and adolescent sexual behaviors. We attempted to fill in this gap by outlining empirical evidence on the protective roles of PYD attributes in youth sexual outcomes. We reviewed local sex education programs and outlined several observations regarding foci, implementation, and evaluation. To conclude, we provided suggestions to inform practice in the future development and implementation of sex education programs to promote sexual health among youths.

Abstract
Objectives: The prevalence and correlates of sexual risk behaviors among unmarried youth in Thailand are poorly documented. The objectives of this study were to compare the differences in sexual behaviors across age groups and gender and to identify the relationships between sexual risk behaviors and general health risk behaviors among unmarried Thai youth. Methods: A population-based, nationally representative, cross-sectional survey was conducted between January and March 2013. The Thai version of the Youth Risk Behavior Survey questionnaire was used to collect data from 800 unmarried Thai youth. Results: Majority of the respondents (65.9%) had not engaged in any sexual risk behavior, 18.7% had engaged in 2–3 sexual risk behaviors, and only 5.5% had engaged in a single sexual risk behavior. Current sexually active youth had higher risk of participating in physical fights (odds ratio = 3.41, 95% confidence interval = 1.53–7.57), smoking cigarette (odds ratio = 4.05, 95% confidence interval = 1.89–8.67), and drinking alcohol (odds ratio = 2.17, 95% confidence interval = 1.08–4.36). Conclusion: Thai youth were more likely to be involved in multiple sexual risk behaviors than a single sexual risk behavior. Physical fighting was the strongest general health risk behavior associated with the sexual risk behaviors, followed by substance abuse.

Abstract
This study explores youth suicide attempts in Singapore using multiple databases of comprehensive archival records. Three years of medical records related to suicide attempters (N=666) who were admitted to the emergency department of a large teaching hospital in Singapore were subjected to retrospective analysis. Compared to other age groups, a peak in suicide attempts (n=207) was observed in youths aged between 15 and 24 years old (76.3% females; 23.7% males, mean age=19.30, SD=2.89). The model using recognized risk and protective factors was significant in predicting medical lethality, and correctly classified 62.8% of high lethality cases. Only resolution of precipitant made a unique statistical significant contribution. Analysis was separately conducted for males and females. Implications of the findings are discussed.

New evidence about the "dark side" of social cohesion in promoting binge drinking among adolescents. PLoS One 2017; 12:e0178652.

Abstract
Adolescence is characterized by heightened susceptibility to peer influence, which makes adolescents vulnerable to initiating or maintaining risky habits such as heavy drinking. The aim of the study was to investigate the association of social capital with longitudinal changes in the frequency of binge drinking among adolescents at public and private high schools in the city of Diamantina, Brazil. This longitudinal study used two waves of data collected when the adolescents were 12 and 13 years old. At the baseline assessment in 2013 a classroom survey was carried out with a representative sample of 588 students. In 2014, a follow-up survey was carried out with the same adolescents when they were aged 13 years. The Alcohol Use Disorder Identification Test-C (AUDIT C) was employed for the evaluation of alcohol intake. Our predictor variables included sociodemographic and economic characteristics (gender, type of school, mother's education, family income) and Social Capital. For evaluation of social capital, we used the Social Capital Questionnaire for Adolescent Students (SCQ-AS). Descriptive and bivariate analyzes were performed (p <0.05). The log-binomial model was used to calculate prevalence ratios (PR) and 95% confidence intervals. The two-tailed p value was set at <0.05. The prevalence of binge drinking in 2013 was 23.1% and in 2014 the prevalence had risen to 30.1%. Gender (PR 1.48; 95% CI 0.87–2.52) and socioeconomic status (type of school and mother’s education) were not associated with the increase in the frequency of binge drinking. However, higher social capital was significantly associated with an increase in binge drinking by students. Adolescents who reported that they had an increase in social cohesion in the community/neighborhood subscale were 3.4 times more likely (95%CI 1.96–6.10) to binge drink themselves. Our results provide new evidence about the “dark side” of social cohesion in promoting binge drinking among adolescents.

Abstract
Background Illicit substance use among college students represents one of the most complicated social problems. Studying its predictors could help deal with this problem more efficiently. Aims To determine the prevalence of life time illicit substance use and its predictors among Tunisian college students. Methods A cross-sectional study was conducted in five colleges in the region of Sousse, Tunisia in the 2012-2013 school year. A sample of 556 college students responded to an anonymous self-administrated questionnaire. Collected data concerned socio-demographic characteristics and substances use. Results The mean age of students was 21.8 ± 2.2 years. Females represented 51.8% of participants. Among respondents: 31 (5.6%) had used illicit substance at least once. Cannabis was the main substance used by 26 (4.7%) students. The average age of the illicit substance use initiation was 19 (±2.5) years while it was almost 17 (±3) years for both tobacco and alcohol use initiations. Proportions of male students and academic failure were significantly more important among illicit substance users than among non users. While the most influential factors on illicit substance use were: alcohol use, tobacco use and low socioeconomic level. Conclusion This study highlights the strong association between the other risk behaviors and illicit drug use. Future interventions should focus on the whole risk behaviors simultaneously at late adolescence with regard to the environmental context.

Abstract
Background A high coverage of human papillomavirus (HPV) vaccination is required to achieve a clinically significant reduction in disease burden. Countries implementing free-of-charge national vaccination program for adolescent girls are still challenged by the sub-optimal uptake rate. Voluntary on-site school-based mass vaccination programs have demonstrated high coverage. Here, we tested whether this could be an option for countries without a government-supported vaccination program as in Hong Kong. Method A Home-School-Doctor model was evolved based on extensive literature review of various health promotion models together with studies on HPV vaccination among adolescent girls. The outcome measure was uptake of vaccination. Factors associated with the outcome were measured by validated surveys in which 4,631 students from 24 school territory wide participated. Chi-square test was used to analyze association between the categorical variables and the outcome. Multivariate analysis was performed to identify independent variables associated with the outcome with vaccine group as case and non-vaccine group as control. Results In multivariate analysis, parental perception of usefulness of the Home-School-Doctor model had a very high odds ratio for uptake of HPV vaccination (OR 26.6, 95 % CI 16.4, 41.9). Paying a reasonable price was another independent factor associated with increased uptake (OR 1.71, 95 % CI 1.39, 2.1 for those with parents willing to pay US$125-250 for vaccination). For parents and adolescents who were not sure where to get vaccination, this model was significantly associated with improved uptake rate (OR 1.66, 95 % CI 1.23, 2.23). Concerns with side effects of vaccine (OR 0.70, 95 % CI 0.55, 0.88), allowing daughters to make their own decisions (OR 0.49, 95 % CI 0.38, 0.64) and not caring much about daughters’ social life (95 % CI 0.45, 0.92) were factors associated with a lower uptake. Discussion The findings of this study have added knowledge on how a school-based vaccination program would improve vaccine uptake rate even when the users need to pay. Our findings are consistent with other study that the most acceptable way to achieve high uptake of HPV vaccine is to offer voluntary school-based vaccination. Conclusion A model of care incorporating the efforts and expertise of academics and health professionals working closely with school can be applied to improve the uptake of vaccine among adolescent girls. Subsidized voluntary school-based vaccination scheme can be an option.

Abstract
OBJECTIVE Positive changes in diet have been observed in research carried out in the United States from the use of "Escape from Diab" (Diab), a health videogame designed to lower the risk of obesity and type 2 diabetes. Whether the American story and characters in Diab might be perceived by Hong Kong Chinese children as interesting has not been explored. This study assessed the acceptability and applicability of Diab among Hong Kong Chinese children, whether the Diab story was understood by them, and whether it had potential to influence them both during the game and afterward. SUBJECTS AND METHODS Thirty-four students (21 males, 13 females) 9-12 years of age were included. Upon completion of all the Diab episodes, children completed an immersion scale with 18 items, as well as an individual interview with 10 open-ended questions. RESULTS Children achieved average immersion after playing Diab with the mean score at 39.1 (standard deviation = 9.0), higher than the median (36) of possible scores (range, 18-54). Four themes using framework analysis emerged from the interviews, including intuitive feelings about the interface, playing experience, perception of the effect of Diab on behavior change, and the applicability of Diab to Hong Kong children. The story and game developed for American children were found acceptable and applicable to Hong Kong Chinese children. CONCLUSIONS The combination of quantitative and qualitative methods confirmed the acceptability and applicability of Diab to Hong Kong Chinese children.

Abstract
Background The socioeconomic inequalities in child health continue to widen despite improved economy. Objective To investigate the correlation between socio-economic factors and health risk behaviors and psychosocial well-being of children in Hong Kong. Hypothesis The null hypothesis is that for this particular developed region, there exists little or no correlation between social-economic factors and health risk behaviors and psychosocial well-being of children. Design Cross sectional territory wide survey. Participants Caregivers of 7,000 children in kindergartens in Hong Kong. Measuring tools Youth Risk Behavior Surveillance questionnaire, health-related knowledge and hygienic practice questionnaire, and Children Behavior Checklist (CBCL). Results Children were less likely to have somatic complaints and anxiety/depression as reflected by CBCL scores coming from families of higher income, not being recipients of social assistance, with fathers in employment, and with higher parental education. Children with only mother or father as caretakers had lower odds ratios (ORs) 0.71 (95% CI 0.58-0.89) and 0.53 (95% CI 0.33-0.84) respectively to have the habit of eating breakfast, whilst parental education at post-secondary level and higher family income had higher ORs 1.91 (95% CI 1.31-2.78), and 1.63 (95% CI 1.11-2.39). Fathers unemployed, relatives as main caretakers and living in districts with low median household inome incurred higher ORs, as 1.46 (95% CI 1.10-1.94),1.52 (95% CI 1.27-1.83) and 1.17 (95% CI 1.02-1.34) respectively, of watching television over two hours daily, whilst children with parental education at secondary level or above incurred lower OR 0.33 (95% CI 0.24-0.45). Children with parental education at post-secondary level and higher family income had lower ORs of 0.32 (95% CI 0.48-0.97) and 0.52 (95% CI 0.34-0.79) respectively, with regard to exposing to passive smoking, and reversed for those living in districts with lower median household income, lower family income and recipient of CSSA with ORs 1.24 (95% CI 1.06-1.44) and 1.6 (95% CI 1.09-2.37) respectively. Conclusion Null hypothesis was not supported. A strong gradient was still found to exist among different socio-economic groups for various health-related behaviors in developed society like Hong Kong.

Abstract
Background: Substance use among college students in Iran is a serious problem. Determining the pattern of substance use among University students is an important issue for implementing prevention and treatment programs. Objectives: The present survey attempts to determine the prevalence of substance usage and associated risk factors among the students of Jahrom University of Medical Sciences and Islamic Azad University of Jahrom, Jahrom, Iran. Patients and Methods: This cross-sectional study was carried out from December 2012 to February 2013 and included 1149 randomly selected students of two Jahrom universities. A standard questionnaire was used for data gathering. Data were analyzed using the SPSS version 15 for Windows. T-test and Chi-square T-test and Chi-square and Logestic regression tests were used for data analysis. Results: Tobacco (28.3%), alcohol (13.0%), and cannabis and marijuana (5.2%) were the most common substances used by the students. The prevalence of substance use among the male students was significantly higher (OR: 1.5, 95%CI: 1.42 - 2.68, P < 0.001). The risk of at least single episode of substance usage was higher among the students which were living alone (OR: 3.03, 95%CI: 1.74 - 5.28, P < 0.001) The most important motivators for beginning substance use were curiosity, in 46.4%, and seeking pleasure, in 28.8%. Conclusions: Substance usage is considered as a risk factor for students’ health among University students in Iran. Design of educational courses addressing the detrimental effects and dire consequences of substance usage could help to improve control programs. Universities could improve their drug abuse control programs by focusing on the high risk groups determined by relevant studies.

Abstract
Childhood obesity is a global public health issue, including in the Chinese setting, and its prevalence has increased dramatically throughout the last decade. Since the origins of childhood obesity may lie in the pre-school period, factors relating to very young children’s food consumption should be investigated. Parental influence, including feeding style, is the major determinant of childhood dietary behaviour through altering food provision and social environment. However, the applicability of previous research on parental feeding styles was limited by small sample size. To evaluate the influence of parental feeding styles on children's dietary patterns, a cross-sectional study was conducted among 4553 pre-schoolers in Hong Kong. Information was obtained about dietary intake and how regularly they had breakfast, using previous health surveillance surveys taken among primary school students. Parental feeding styles were assessed by a validated Parental Feeding Style Questionnaire and categorized into ‘instrumental feeding’, ‘emotional feeding’, ‘prompting and encouragement to eat’ and ‘control over eating’. Multivariable analysis was performed, adjusted for demographic information. Instrumental and/or emotional feeding was found to relate to inadequate consumption of fruit, vegetables and breakfast, and positively correlated with intake of high-energy-density food. Encouragement on eating was associated with more frequent consumption of fruits, vegetables, dairy products and breakfast. Control over eating correlated with more frequent consumption of fruits, vegetables and breakfast, and less consumption of dairy products and high-energy-density food. The present study has provided evidence on the associations between parental feeding styles and dietary patterns of Hong Kong pre-school children from a reasonably large population. Parents should avoid instrumental and emotional feeding, and implement control and encouragement to promote healthy food intake. Longitudinal studies and interventions on parental feeding style are required to confirm the research findings.

Abstract
Background Now a days the utilization of Acceptance / Commitment and Emotion Regulation Strategy as a comprehensive treatment plan has been discussed in both the prevention and the control of destructive and risky behaviors. Treatment based on Acceptance/Commitment and Emotion Regulation was effective in both the improvement and the control of high-risk behaviors of students with dyscalculia. Objectives The purpose of this study was to investigate the effectiveness of Acceptance and Commitment, and Emotional Regulation training in high-risk behaviors of students with dyscalculia. Materials and Methods This research was experimental, with pre-test, post-test and a control group. The statistical universe of this study included all sixth-grade male students in Ardabil city in the academic year of 2012-2013 (A.H.). The subjects of this study involved 800 sixth-grade elementary students in Ardabil province, selected using a multi-stage cluster sampling. From among them, 60 students with dyscalculia were selected using random sampling method after the initial diagnosis by structured clinical interview and the Keymath Mathematic test. Twenty pupil were selected for either the experimental or the control group. To collect data, the questionnaires of "Keymath Mathematic test" and High-risk Behavior" were used. Results The results of Multivariate Analysis of Variance (MANOVA) showed that "Acceptance / Commitment and Emotion Regulation" treatment trainings were effective in reducing high-risk behaviors, in a manner that they led to a reduction in negative emotions, self-destructive and impulsive behaviors of students with math disorder (dyscalculia). Conclusions It can be concluded that teaching these skills to the students has been influential in enhancing awareness level and change or positive attitude creation in the subjects. Therefore, it is essential to design and implement interventions based on "prevention caused by the peer group, in collaboration with the parents either at the school or at home among the family members".

Abstract
A comprehensive understanding of research on the physical activity (PA) of Hong Kong youth is necessary to develop specific and effective intervention strategies. This review summarizes existing evidence in studies on PA among the Hong Kong youth. An electronic literature search was conducted using MEDLINE, SPORTDiscus, ERIC, and HighWire database. Forty-five studies published from 1987 to 2012 were included in this review. The findings are presented in five categories, namely, health benefits of PA, participation in PA, assessment of PA, correlates of PA, and interventions to promote PA. The results indicate that PA among the youth in Hong Kong has attracted concern in the past decade. Specifically, extensive studies focused on the areas of health benefits of PA, participation in PA, and correlates of PA. Research into context-specific correlates of PA and tailored PA promotion programs for the Hong Kong youth is warranted in the future.

Abstract
This study explores the association of family process and peer influences with risk behaviors of adolescents. A total of 805 students were recruited from secondary schools. The results showed that adolescents who have parents who are “authoritarian” (OR = 1.856) were more likely to smoke. Adolescents who have conflicts with their parents (OR = 1.423) were more likely to drink. Those who have parents who are “permissive” were less likely to drink (OR = 0.885). Having friends who smoked (OR = 5.446) or drank (OR = 1.894), and friends’ invitation to smoke (OR = 10.455) or drink (OR = 11.825) were the dominant contributors to adolescent smoking and drinking. Interventions are needed that recognize the strength of the parent-child relationship, as well as strengthen family functioning through improved interpersonal, parenting, and monitoring skills.

Abstract
Risk-taking behaviors have negative consequences on adolescent and young adult’s health. The aim of this study was to identify the subgroups of college students on the basis of risk-taking behaviors and to assess the role of demographic characteristics, religious beliefs, and parental support on membership of specific subgroup. The cross-sectional study took place in Tabriz (northwest of Iran) in April and May of 2011. The randomly selected sample consisted of 1,837 college students. A survey questionnaire was used to collect data. Latent class analysis was performed to achieve the study’s objectives. Four latent classes were identified: (a) low risk, (b) cigarette and hookah smoker, (c) sexual and drinking risk-takers (for males)/sexual risk takers (for females), and (d) high risk. Notably, 13.3% of the males and 4.3% of the females were in the high-risk class. The results identified evidence of protective influence of familial support and religiosity on risky behaviors. A fair number of college students, males in particular, were identified as high risk-takers. Design and implementation of preventive interventions for this segment of the population are necessary. Higher level of familial support and religiosity may serve as preventive factors in risk-taking behaviors.

Abstract
AIM To explore the relationship between personal characteristics and smoking initiation among adolescents in Hong Kong. BACKGROUND Adolescents have been initiating cigarette smoking at an increasing rate in recent years. Preventing tobacco use among young children has become one of the most effective strategies to reduce the harmful effects of tobacco use. DESIGN A cross-sectional study. METHODS Secondary students were recruited by convenience sampling from schools in the New Territories of Hong Kong in 2010. Questionnaires were used to collect information relating to their demographic and personal characteristics, including behavioural control, coping styles, sociability, locus of control, rebelliousness, self-esteem, emotional distress, and intention to smoke. RESULTS A total of 644 secondary students were recruited. The prevalence of having ever tried smoking was 19·4% and that of regular smoking was 3·9% among these students. The results of this study show that secondary students who were living in public housing and had lower behavioural control and higher smoking intention were more likely to have tried smoking or to be regular smokers, indicating that these factors contribute to smoking initiation among secondary students. CONCLUSIONS The personal characteristics of secondary students do play a role in smoking initiation. Parents and school personnel should work together to help young people to improve their self-esteem and behavioural control and to overcome their rebelliousness. The causes of smoking intention should also be explored to stop young people from picking up their first cigarette.

Abstract
Despite global progress in tobacco control, data are needed for subgroups with increased risk of tobacco use for more effective smoking prevention. Survey data from a random sample of 6,486 youth in grades 7, 8 and 9 were derived from the project Chinese Student Health Survey. Prevalence and hazards of smoking onset were compared by gender and immigrant status. Mediation analysis was used to assess factors that may mediate the impact of immigrant status on smoking. Immigrant students had a much higher risk of hazards of smoking initiation than non-immigrant students. Parental monitoring and parental smoking significantly mediated the effect of immigrant status on early smoking onset. In addition, gender differences in the prevalence of smoking and hazards of smoking onset in our study were smaller than those reported by others targeting non-Hong Kong Chinese youth. Findings of this study imply that immigrant children and girls in Hong Kong are at increased risk to tobacco use. Special attention should be paid to these subgroups for prevention intervention. Prevention intervention for immigrant children should address parental smoking and parental monitoring. Reduced gender difference in smoking among Hong Kong youth suggests an emerging trend for more Chinese girls on the Mainland to smoke along with the rapid socioeconomic development.

Abstract
Suicidal trends and related characteristics such as sociodemographic factors, psychological factors, and health behaviors can differ between countries. This study investigated the predictors of suicidal ideation and attempted suicide including health behaviors among American and Korean youth from two national representative data sets. In both countries, depression was the most predominant predictor to suicidal ideation and attempted suicide. Unique predictors of suicidal youth in each country were also found. In America, attempted suicide was predicted by poor body image, whereas in Korea attempted suicide was predicted by medical diagnosis such as asthma, concern about weight, and alcohol consumption. The value of our approach lies in the comparative analysis of analogous and unique characteristics of suicidal youths in these two huge data sets from different countries. These results should be helpful for school and mental health care providers to plan interventions for youth at risk of suicide to prevent suicidal completion in these nations.

Abstract
PURPOSE The study compared differences in overweight prevalence, weight perception, and weight-related practices among high school students in five large Chinese and U.S. cities, and informed interventions for childhood obesity in China and the U.S. METHODS The data used was collected in 2003 from a representative sample of high school students in Hong Kong, Macau, Taipei, New York and Los Angeles. RESULTS The prevalence of overweight high school students in New York City and Los Angeles was about twice as high as in Hong Kong, Macau, and Taipei; however, the proportion of Chinese students perceiving themselves to be overweight was 15% higher than their U.S. counterparts. Independent of actual weight status, perceived overweight was significantly associated with weight control practices (p < .05). U.S. students showed higher levels of moderate and vigorous physical activity, but more hours of watching television than their Chinese counterparts. CONCLUSION The continuing pandemic of overweight among youth fosters weight dissatisfaction, which may increase unhealthy weight control practices. Interventions should be designed to prevent overweight without precipitating unhealthy weight control practices by emphasizing an increase in physical activity and a reduction in time watching television.

Abstract
This study investigated whether the consumption of fruit and vegetable by Chinese primary students in Hong Kong is associated with their mother's (1) nutrition knowledge on fruit and vegetables; (2) attitude towards healthy eating; and (3) fruit and vegetable consumption. Fourth- and fifth-grade students from 10 primary schools located in different districts, along with their mothers, were invited to each fill-in a questionnaire related to their diet intake. Accomplished questionnaires were matched and analysed. There were 1779 mother-child pairs who were successfully matched. Chi-square analysis revealed that students' fruit consumption is associated with their mother's (1) knowledge on fruit and vegetables (P = 0.006); (2) attitude towards healthy eating (P = 0.010); and (3) fruit consumption (P < 0.001). Students' vegetable consumption exhibited the same association with their mother's (1) knowledge (P < 0.001), (2) attitude towards healthy eating (P = 0.005), and (3) vegetable consumption (P < 0.001). Logistic regression showed that knowledge, attitude and dietary practice of mothers were independent factors associated with the consumption of fruit and vegetables by students and are not influenced by the level of education and household income. The results highlight the important role of parents in promoting fruit and vegetable consumption to primary students. It reaffirmed the importance of parent nutrition education in the formulation of a comprehensive health promotion strategy to school-aged children.

Abstract
This study enhanced nutritional knowledge in an education program and encouraged healthy dietary habits and regular physical activity among teenagers. A total of 203 adolescents from a secondary school in Hong Kong took part in the study. Their Body Mass Index, dietary habits, and physical exercise pattern were recorded and examined before and after the health education program. The prevalence of overweight and obesity, together with the fat composition, were high among the participants before the nutrition education program. There was a marked gain in knowledge upon its completion. A follow-up action conducted 3 months later revealed positive outcomes in relation to the diet and physical activity level. The teenagers were able to take control of their health and requested the tuck shop to sell more healthy food and reduce the supply of unhealthy items. The educational initiatives in dietary habits and physical activities proved to be effective in encouraging the teenagers to eat more healthily and to adopt an active lifestyle.

Abstract
The aims of this study were to examine the frequency and correlates of problem behaviors among Hong Kong adolescents. It is a cross-sectional survey targeting secondary forms 1 to 3 (equivalent to grades 7-9 in the United States) students (N = 1029). A self-administered questionnaire was used as the measurement tool. The study found that there are intercorrelations of problem behaviors in adolescence, such as tobacco use, alcohol use, drug abuse, and having connections with triad society. Given the intercorrelations among problem behaviors, identification of a single type of problem behavior in adolescents can help discover the likelihood of the occurrence of other problem behaviors. It can facilitate identification and intervention at an early stage. The results provide some insights for the concerned authorities to develop a syndrome approach addressing problem behaviors.

Abstract
BACKGROUND To describe the characteristics of a population with high-risk sexual behaviours and associations between sexual intercourse, high-risk sexual behaviours and socio-demographic characteristics among Chinese urban adolescents. METHODS In 2005, 109,754 students in grades 10-12 and 33,653 college students were anonymously surveyed using a Chinese Youth Risk Behaviour Survey. Demographic variables and indicators of forced sex, condom use and unintended pregnancy were analysed with multiple logistic regressions. RESULTS Of students surveyed, median age was 17.6 (range 14-24 years) and 76,233 were female (53.2%); 4.8% of high school students reported had experienced sexual intercourse; of these, 32.8% reported had forced sex; 11.3% of college students reported had experienced sexual intercourse and of these, the prevalence of forced sex, condom use and unintended pregnancy were 23.5, 49.7 and 24.2%, respectively. School type and socioeconomic status were found to be independently associated with sexual intercourse and forced sex for high school students. For college students, educational level, school type, family structure, maternal education and socioeconomic status were independently associated with high-risk sexual behaviours. CONCLUSION This study highlights the association between high-risk sexual behaviours and school type and socioeconomic status. These results strongly suggest the importance of providing sex education in high schools and lower socioeconomic areas.

Abstract
BACKGROUND The association between diet and acne vulgaris has long been suggested but remains unproven in western medicine. In contrast, the diet-acne relationship is considered important in traditional Chinese medicine (TCM). Aim. To investigate the association between diet and acne, using a TCM approach. METHODS Using a cross-sectional study of 322 entrants to a university in Hong Kong, China, we examined the participants' clinical severity of acne using the Global Acne Grading System and the participants' yin and yang scores using a quantitative method. We then divided them into two groups, a yin-predominant group (yin-PG) and a yang-predominant group (yang-PG) before the diet-acne relationship was investigated. RESULTS In total, 82 (25.2%) participants were in the clinical acne group and 240 (74.5%) were in the reference group. There were 155 (48.1%) participants in the yin-PG and 167 (51.9%) in the yang-PG group. No association of diet and acne was found when the participants were considered as a homogenous group. In yin-PG, intake of foods from street stalls (P = 0.04) was significantly associated with a lower incidence of acne. In yang-PG, the intake of desserts (P = 0.04) and fresh fruit juices (P = 0.02) was significantly associated with a higher incidence of acne, whereas the intake of dairy and soy products (P = 0.04) was significantly associated with a lower incidence of acne. CONCLUSIONS The application of a TCM approach led to the detection of significant associations between diet and the incidence of acne.

Abstract
The WHO health promoting school (HPS) approach covers key areas including school-based programmes improving students' psychological health, but there have been few studies evaluating the resilience performance of these schools. This study compared the resilience scores between schools within the healthy school award (HSA) scheme (HPS group) and those not (non-HPS group). We conducted a cross-sectional survey of grade-one students (aged 12), all teachers and parents of mainstream secondary schools recruited by stratified random sampling in one large Territory of Hong Kong using validated resilience questionnaires during November-December 2005. Four non-HPS and four HPS secondary schools were recruited, respectively, involving 1408 students, 891 parents and 91 teachers, with similar baseline characteristics. The HPS students were found to have better scores than non-HPS students (average age 12.4 year-old in both groups) in all dimensions with significantly higher scores in 'Peer Support' (p = 0.013), 'Making a Difference' (p = 0.011), 'About Me' (p = 0.027) and 'Generally Happy' (p = 0.011). There was no difference in the scores between non-HPS and HPS parents. The HPS teachers reported significantly higher scores in 'Health Policies' (p = 0.023), 'Social Environment' (p = 0.049), 'School Community Relations' (p = 0.048), 'Personal Skills Building' (p = 0.008) and 'Partnership & Health Services' (p = 0.047). The secondary HPS students and teachers reported significantly higher resilience scores than those of non-HPS. This study shows that the HSA scheme under WHO has the potential to exert positive changes in students and teachers and the concept of HPS is effective in building resilience among major school stakeholders.

Abstract
Diet composition influences net endogenous acid production (NEAP), which may affect bone health. No studies are available to relate dietary estimate of NEAP to bone health in Chinese adolescents. This study examined the association of dietary estimates of NEAP with bone mineral status in Hong Kong Chinese adolescents. Baseline data on 171 boys and 180 girls aged 10-12 years from the Hong Kong Adolescent Bone Health Cohort Study were presented. Weight, height, Tanner stage and dietary intakes by FFQ were collected. NEAP was estimated from diet using Frassetto's method. Bone area (BA), bone mineral content (BMC) and bone mineral apparent density (BMAD) of total hip, lumbar (L1-L4) spine and whole body were estimated by dual-energy X-ray absorptiometry (DXA). No significant association was observed between BMC or BMAD and energy-adjusted NEAP or other nutrients. BA was significantly and positively associated with BMC at all sites in both sexes. Weight was significantly and positively associated with BMC in hip and spine in both sexes. Height was negatively correlated with hip BMC for boys and whole body BMC for girls. Pubertal stage was significantly and positively associated with BMC in all sites in both sexes. Weight and height contributed most of the variability in BMAD at different sites. The results suggest that anthropometric characteristics and pubertal stage are more influential than dietary NEAP in determining bone mineral status of Hong Kong Chinese adolescents. However, the methodological weaknesses regarding the use of DXA and FFQ in the present sample require attention.

Abstract
OBJECTIVES The objectives of this study were to measure the association of general and oral health-related behaviours with living conditions and to explore the interrelationships between general and oral health-related behaviours in Chinese urban adolescents. METHODS A cross-sectional survey of 2662 adolescents was conducted in eight Chinese provincial capitals. The response rate was 92%. The study population was selected through multistage cluster sampling and comprised three age groups: 11, 13 and 15 years. Data on oral and general health, lifestyles as well as living conditions were collected by means of self-administered structured questionnaires. Several additive indices were constructed from answers to the questions on specific behaviour, and participants were categorized according to scores on each component of health-related behaviour for statistical analyses by frequency distributions, regression analyses and factor analyses. RESULTS Oral health-related behaviours among adolescents were associated with socioeconomic status of parents, school performance and peer relationships. The odds of a dental visit was 0.63 in adolescents of poorly educated parents and the corresponding figure for regular oral hygiene practices was 0.62. Odds of tobacco use was 3 for adolescents with poor performance in school while odds of consuming sugary foods/drinks was 1.3. Adolescents with high levels of preventive oral health practices also demonstrated general health-promoting behaviours. In factor analysis of general and oral health-related behaviours, three factors were isolated: (a) risk behaviours (loadings 0.48-0.66), (b) health-promoting behaviours (loadings 0.60-0.64) and (c) help-seeking behaviours (loadings 0.56-0.67). CONCLUSION The findings support a multidimensional model of health behaviour. Several approaches and multiple methods should be applied in oral health education in order to modify behaviours that affect oral health.

Abstract
BACKGROUND/OBJECTIVES To examine the daily intake of bone health-related nutrients and to explore the association between diet composition and estimated net endogenous acid production (estimated NEAP) in Hong Kong Chinese adolescents. SUBJECT/METHODS In total, 171 boys and 180 girls aged 10-12 years of Chinese origin from nine primary schools from the Hong Kong Adolescent Bone Health Cohort Study. The study design used food frequency questionnaire. Mean daily intakes of foods and selected nutrients were estimated. Mean percentage of nutrient intake contributed by different food groups was presented. Frassetto's method was used to calculate the estimated NEAP from the diet's protein to potassium ratio. RESULTS There was no significant difference in the energy-adjusted intakes of most nutrients between boys and girls, except for intakes of vitamins C and D. Mean protein, sodium and potassium intakes were higher than the Chinese dietary reference intake (DRI), whereas mean intakes of magnesium, calcium and vitamin D were lower than the DRI. Boys had significantly higher estimated NEAP than girls (P=0.0051). Estimated NEAP was significantly positively correlated with meat intake and negatively associated with the consumption of fruits, vegetables, legumes, beverages and dairy products. CONCLUSIONS The results highlight the importance of considering whole diet quality when interpreting the effects of single nutrient or diet's net acid load on bone. The effect on high protein intake and low fruit and vegetable intake on the long-term bone health of Hong Kong Chinese adolescents warrants attention.

Abstract
OBJECTIVES The aim of this study was to determine the factors related to the adoption of effective methods for preventing AIDS, particularly condom use, in university students from Spain and Portugal. STUDY DESIGN A cross-sectional and cross-cultural study. Data were obtained by questionnaire. METHOD The variables analysed in the sample of Spanish and Portuguese students were: the perceptions of benefits and barriers to condom use; perceived self-efficacy in the negotiation of condom use; and in using a condom in difficult situations; and the perceptions of vulnerability, severity and risk. RESULTS The data showed similarities between the Spanish and Portuguese students in the high frequency of condom use and the weight of self-efficacy for negotiating and ensuring condom use. However, data also reflected differences between the countries especially with regard to the weight of benefits and costs in the adoption of prevention methods. CONCLUSIONS These findings suggest that the different realities for each country or context must be considered in the design of AIDS prevention programmes aimed at late adolescents. Whereas in both countries prevention programmes should encourage the ability to negotiate condom use, Portuguese programmes must underline the benefits of condom use, and Spanish programmes should aim to analyse the importance of barriers to condom use for the students to reduce these and to replace costs with benefits.

Abstract
BACKGROUND The Health Promoting School (HPS) is a WHO sponsored framework, compiled to enable education and health sectors to be more effective in school based initiatives. AIMS This study attempted to test the hypothesis that students from schools that had comprehensively embraced the HPS concept as indicated by the Healthy School Award, were better, in terms of health risk behaviour, self reported health status, and academic results, than students from schools that did not reach the standard of the award. METHODS AND RESULTS The results presented came from nine schools (four primary and five secondary) applying for accreditation of the Healthy Schools Award after adopting the HPS framework for two years. Regular consultancy support and training were available to all schools. Students had completed before and after surveys to assess their health behaviours, self reported health status, and academic standing before the two year intervention, and at its end. Data from the before and after surveys of the students attending schools that reached certain level of HPS standard as indicated by the award, were compared with students whose schools did not receive the award, and the results showed differences. Some differences were found to be more significant among the primary school students than secondary schools students. This illustrated early intervention for lifestyle changes to be more effective. Students' satisfaction with life also improved if their schools adopted the concept of HPS comprehensively. CONCLUSIONS The results suggest that comprehensive implementation of HPS would contribute to differences in certain behaviours and self reported health and academic status.

Abstract
The objectives of this study were: to describe perceived dental health status and oral health-related knowledge, attitudes, and behavior in Chinese urban adolescents; to assess the associations of oral health variables with socio-economic status and school performance; and to analyse the relative effect of socio-behavioral risk factors on perceived dental health, perceived need for dental care, and experience of dental symptoms. A cross-sectional survey of 2662 adolescents was conducted in eight capital cities in China; the response rate was 92%. The study population was chosen by multistage cluster sampling and covered three age groups: 11, 13, and 15 years. Data on dental and general health were collected by self-administered questionnaires. Self-assessment of dental health of Chinese adolescents was generally good, only 12% of the students answered that their teeth were "poor" or "very poor", and 9% claimed having "poor" or "very poor" gums. Eleven percent of participants said that other students made fun of their teeth; 24% of the respondents were dissatisfied with the appearance of their teeth, and 41% claimed that they had experienced toothache or symptoms during the previous 12 months. Positive attitudes towards dental care were found in all age groups; 67% of adolescents brushed their teeth at least twice a day and 48% of the students used fluoridated toothpaste. Only 26% of the students visited a dentist during the previous 12 months. In all, 6% of the adolescents had tried cigarette smoking at least once, while 41% reported having tasted alcohol drinks. Multivariate regression analyses showed that perceived dental health status and needs were associated with gender, age, unhealthy lifestyles, poor school performance, and socio-economic status. The establishment of school-based health promotion programs in China is urgently needed, and promotion of oral health lifestyles should be integrated with other general health actions.

Abstract
OBJECTIVES To assess parental influence on smoking behaviour by high school students in an Asian culture and to compare the relative importance of parental and peer influence. METHODS A 5% nationally representative sample, including 44 976 high school students in 10th to 12th grade (aged 15-18 years) in Taiwan, were surveyed in 1995. Each completed a long self administered questionnaire. Parental influence was measured by examining both parental behaviour (smoking status) and attitudes (perceived "tender loving care" (TLC) by adolescents). Changes in smoking status were used to determine peer influence, defined as the increase in the likelihood of smoking from grade 10 to 12 in a steady state environment. Odds ratios (ORs) were calculated for parental and peer influence, using logistic regression. RESULTS Adolescents of smoking parents with low TLC had the highest smoking rates and those of non-smoking parents with high TLC had the lowest. The difference was more than twofold in boys and more than fourfold in girls. When either parental smoking status or TLC alone was considered, parental influence was similar to peer influence in boys, but larger than peer influence in girls. However, when smoking status and TLC were considered jointly, it became larger than peer influence for both groups (OR 2.8 v 1.8 for boys and OR 3.9 v 1.3 for girls). CONCLUSION When parental influence is taken as parental behaviour and attitude together, it plays a more important role than peer influence in smoking among high school students in Taiwan. This study, characterising such relationships among Asian populations for the first time, implies that future prevention programmes should direct more efforts toward the parental smoking and parent-child relationships, and not aim exclusively at adolescents in schools.

Abstract
Health-promoting schools (HPS)/healthy schools have existed internationally for about 15 years. Yet there are few comprehensive evaluation frameworks available which enable the outcomes of HPS initiatives to be assessed. This paper identifies an evaluation framework developed in Hong Kong. The framework uses a range of approaches to explore what schools actually do in their health promotion and health education initiatives. The framework, which is based on the WHO (Western Pacific Regional Office) Guidelines for HPS, is described in detail. The appropriate instruments for data collection are described and their origins identified. The evaluation plan and protocol, which underpinned the very comprehensive evaluation in Hong Kong, are explained. Finally, a case is argued for evaluation of HPS to be more in line with the educational dynamics of schools and the research literature on effective schooling, rather than focusing primarily on health-related measures.
