Behavioral Risk Factors Of Non-Communicable Diseases Among A Nationally Representative Sample Of School-Going Adolescents In Indonesia

The health and wellbeing of undergraduate students in Indonesia: descriptive results of a survey in three public universities

Around a quarter of the Indonesian population are adolescents and young adults (AYA), the future leaders of upcoming decades. Investing in AYA current health is important to secure their future health and ability to lead the development of Indonesia. There is a need to comprehensively assess the current health of Indonesia's future leaders. This study describes the health and wellbeing of AYA undergraduates, as well as their risk-taking behaviours, to inform the design of university based primary care services that meet student needs. A multicentre survey of undergraduate students was conducted in three Indonesian public universities from October 2022 to October 2023. The questionnaires were adapted from a similar study at the University of Melbourne and covered the domains of general health, academic outcome, risk-taking behaviours, mental health, social pressures-and-supports, perceived discrimination and awareness of the university health services. The data were analysed descriptively to demonstrate the number and percentages of students experiencing conditions in each domain. A total of 4365 students completed the survey, with an average of 2947 completing each section of the questionnaire. Most of the students perceived their general health as good or very good (n = 2,164; 73.7% from those filing in the section; 49.6% from overall participants) and have GPA > 3 (n = 2903;73.5%; 66.5%). However, high percentages had mild to severe depressive (n = 2,240; 74.7%; 51.3%), and anxiety symptoms (n = 1,696; 56.6%; 38.9%). Some expressed risk-taking behaviours, such as smoking cigarettes (n = 460; 16.6%; 10.5%), already engaged in sexual activities (n = 268, 12.9%; 6.1%). Most participants reported having a dysfunctional family (n = 2,755; 92.3%; 63.1%), gender and sexual discrimination (n = 304; 11.6%; 6.9%;), and only a third are involved in social clubs (n = 876; 33.5%; 20.1%). Half of the overall participants are aware of the university health service (n = 2,066; 79%; 47.3%). Despite having high academic achievement, the high proportion of Indonesian students experiencing mental ill health and risk factors for non-communicable diseases are alarming. Health risks are further exacerbated by low social support indicated by most having a dysfunctional family and few involved in social clubs. Further action is required to heighten student awareness of, and access to, university health services and to ensure these services can address their health and social issues.

The relationship between non-communicable disease risk and mental wellbeing in adolescence: a cross-sectional study utilising objective measures in Indonesia

BACKGROUND

Risk factors for non-communicable diseases (NCDs, cardiovascular diseases, cancers, chronic respiratory diseases, diabetes, and mental disorders) arise in adolescence but are mostly framed as relevant to health in adulthood; little is known about the relationship between co-occurring NCD risks and mental wellbeing in young people. This study aims to describe the prevalence and co-occurrence of distinct NCD risk factors, and how they relate to current mental wellbeing amongst adolescents in Indonesia, a young and populous country where NCD burden is increasing rapidly.

METHODS

We assessed NCD risk and mental wellbeing amongst 1,331 school-based 16-18-year-olds in Jakarta (N = 609) and South Sulawesi (N = 722). Five domains of NCD risk (adiposity, substance use, physical inactivity, excess sedentary time, and diet) were either measured or self-reported. In Jakarta, we also measured blood glucose, triglycerides, cholesterol, and blood pressure. Wellbeing was assessed using three indicators: general quality of life (QoL), physical function QoL, and psychological distress. We used linear regression to estimate the associations between co-occurring risks and wellbeing, adjusted for covariates of wellbeing: province, sex, socioeconomic status, and religion.

RESULTS

NCD risk clustering was common, and more than half of adolescents had co-occurring risks in 3 or more of the 5 domains (58.9% (95%CI 53.7-63.9)). Adolescents with any NCD risk were more likely to report psychological distress, with this relationship most pronounced in those with excess sedentary time spent on video gaming and computer use. A higher number of NCD risk factors was associated with poorer psychological wellbeing and decreased general and physical function QoL. In the Jakarta subsample, reduced HDL and raised blood glucose was associated with psychological distress; and a higher number of risk biomarkers was associated with lower physical function QoL.

CONCLUSIONS

Our analysis also shows that these NCD risks (both individual risks and co-occurring risk count) are related to poorer profiles of mental wellbeing in adolescents, after adjusting for likely confounders.

Associations of lifestyle behaviors with mental health in a nationwide cross-sectional survey of 152,860 Brazilian students

OBJECTIVE

To evaluate the association between modifiable lifestyle behaviors and mental health indicators in Brazilian adolescents.

METHODS

This cross-sectional study used data from the 2019 National Survey of School Health including 152,860 students. The lifestyle behaviors and mental health indicators were obtained from a self-reported questionnaire. Logistic regression analyses were used to examine the association between lifestyle behaviors and mental health indicators.

RESULTS

Infrequent healthy eating (OR 1.22; 95%CI 1.14-1.31), being inactive (OR 1.82; 95%CI 1.65-2.01), smoking (OR 1.24; 95%CI 1.10-1.40), and irregular school attendance (OR 1.31; 95%CI 1.22-1.40) were associated with not having close friends. Additionally, not having close friends was also associated with unhealthy eating (OR 0.86; 95%CI 0.81-0.92) and alcohol consumption (OR 0.81; 95%CI 0.75-0.87). Infrequent healthy eating (OR 1.29; 95%CI 1.24-1.33), frequent unhealthy eating (OR 1.39; 95%CI 1.35-1.43), being inactive (OR 1.12; 95%CI 1.07-1.18), excessive screen time and sitting (OR 1.10; 95%CI 1.07-1.14 and OR 1.68; 95%CI 1.63-1.73, respectively), smoking (OR 1.26; 95%CI 1.19-1.34), alcohol (OR 1.33; 95%CI 1.28-1.37), drugs (OR 1.13; 95%CI 1.05-1.22), and irregular school attendance (OR 1.53; 95%CI 1.48-1.59) were associated with worse self-rated mental health.

CONCLUSIONS

Various lifestyle behaviors are associated with different indicators of mental health.

Prevalence and determinants of behavioral risk factors for noncommunicable diseases among students aged 13-19 years in Turkey

OBJECTIVE

The aim of this study was to investigate the prevalence and determinants of behavioral risk factors for noncommunicable diseases (NCDs) among students aged 13-19 years in Turkey.

METHODS

This cross-sectional study included a total of 1218 high-school students (mean age = 15.97 years; 57.6 % females) in Turkey. A facilitated survey in the form of a questionnaire was used to gather data. Questions from the Global School-Based Student Health Survey were adapted for the study, and the responses were analyzed using IBM SPSS Statistics 28. Binary logistic regression and Poisson regression were applied to identify the contributing factors.

RESULTS

The prevalence of inadequate fruit and vegetable consumption was 85.5 %, sedentary leisure behavior 80.9 %, physical inactivity 65.3 %, carbonated soft drink consumption 60.4 %, overweight or obesity 38.1 %, current tobacco use 23.1 %, and current alcohol use 14.5 %. The adjusted Poisson regression analysis showed that the odds for having behavioral risk factors were increased by being male, being in grade 11, and attending physical education classes, whereas the odds were reduced by having multiple psychological distress issues, regularly attending school, and having moderate or high parental support.

CONCLUSION

The prevalence of clustering of modifiable risk factors for NCDs was high among students aged 13-19 years in Turkey, and there is a need to mount effective interventions. Risk factors for these diseases are often preventable: Appropriate health interventions before, during, and after pregnancy as well as throughout childhood and adolescence can significantly reduce their prevalence.

Towards responsive policy and actions to address non-communicable disease risks amongst adolescents in Indonesia: insights from key stakeholders

Background

Non-communicable diseases (NCDs) such as cancer, diabetes, heart disease, mental disorder and chronic lung conditions are the leading cause of death and disability in Indonesia. Adolescence is when risks for NCDs emerge and it is also an important life stage for intervention, yet young people are often at the margins of NCD policy and actions. This study aimed to understand how policies and actions should address NCD risks (tobacco smoking, inadequate physical activity, and diet) for adolescents in Indonesia, and how young people can be meaningfully involved.

Methods

Qualitative in-depth interviews over videoconference (n = 21) were conducted in English or Bahasa with stakeholders in Indonesia. Participants included policymakers, implementation partners, and advocates who were focused on adolescent health or NCDs. Interviews were recorded, transcribed, translated, and thematically analysed using NVivo12. Findings were disseminated to participants for validation and feedback. Youth participants (n = 7) attended an additional workshop and considered recommendations and actions arising from this research.

Findings

Participants identified that government and non-government organisations are acting on NCDs in Indonesia, but few of the existing initiatives target adolescents, and adolescent services rarely addressed NCD risks. Participants also felt that policies to protect adolescents from NCD risks (i.e., smoke-free areas in public) were not always enforced. For programs or initiatives focused on adolescent health, those that had engaged adolescents as co-creators and leaders were perceived to be more successful. As such, participants recommended more meaningful engagement of young people, including young people's leadership of initiatives. Additional recommendations included the need for intersectoral engagement and a 'whole-of-government' approach to prevention given the complex determinants of NCD risks, and the need for evidence-based actions that are underpinned by quality data to enable monitoring of progress.

Interpretation

There is a recognised need to strengthen policies and actions to address NCD risks amongst adolescents in Indonesia. Meaningful youth engagement that allows young people to take the lead, intersectoral actions, and evidence-based data driven responses were key strategies identified.

Food insecurity is associated with multiple psychological and behavioural problems among adolescents in five Caribbean countries

The study aimed to assess associations between food insecurity and multiple psychological and behavioural problems among adolescents in five Caribbean countries. Data from national and cross-sectional school health surveys from 9,956 adolescents (15 years, median age) in Trinidad and Tobago, Suriname, Jamaica, Anguilla and the Dominican Republic in 2016-2017 were analyzed in 2016-2017. Results show that the prevalence of moderate (rarely or sometimes) past-month food insecurity was 35.9% and severe (mostly or always) food insecurity was 4.6%. Severe food insecurity among adolescents ranged from 2.9% in Dominican Republic to 11.2% in Suriname. In adjusted logistic regression analyses, the higher severity of food insecurity was associated with negative psychological outcomes (loneliness, suicidal ideation, suicide plan, suicide attempt, anxiety, current tobacco use and any trouble from alcohol use) and negative behavioural outcomes (truancy, bullied, physically attacked, physical injury, and multiple sexual partners). Two out of five adolescents experienced some form of food security. Food interventions, such as school feeding programmes, are warranted to reduce negative psychosocial outcomes.

Adherence to the healthy lifestyle guideline in relation to the metabolic syndrome: Analyses from the 2013 and 2018 Indonesian National Health Surveys

In this study, we aimed to investigate differences in lifestyle factors and prevalence of metabolic syndrome (MetS) in the Indonesian population between 2013 and 2018. In addition, we investigated whether adherence to the 2015-released national healthy lifestyle guideline (‘GERMAS’) is associated with MetS in different sex, age, urban/rural, and BMI categories. We performed cross-sectional analyses in individuals aged >15 of the 2013 (n = 34,274) and 2018 (n = 33,786) Indonesian National Health Surveys. A stratified, multi-stage, systematic random sampling design and the probability proportional to size method were used to select households in the 34 provinces across the country. MetS was defined according to the Joint Interim Statement Criteria, and adherence to ‘GERMAS’ guideline was defined as fulfilling the national healthy lifestyle recommendations of ≥150 min/week physical activity (PA), ≥5 portions/day fruit and vegetable (FV), no smoking (NS), and no alcohol consumption (NA). We examined the associations of each lifestyle factor with MetS using logistic regression categorised by sex, age groups, urban/rural, and BMI, and adjusted for sociodemographic factors. We observed that men who adhered to the guideline had lower odds ratio of MetS [OR(95%CI) associated with PA: 0.85(0.75–0.97); NA: 0.75(0.56–1.00)] than non-adherent men. Middle-aged adults who adhered to the guideline had lower OR of MetS [PA: 0.85(0.72–1.01); FV: 0.78(0.62–0.99); NA: 0.66(0.46–0.93)] than non-adherent adults <45 years. The adherent urban population had lower OR of MetS [FV: 0.85(0.67–1.07); NA: 0.74(0.52–1.07)] than the non-adherent urban population. Those with overweight or obesity who adhered to the guideline had relatively lower odds of MetS than those who did not. In conclusion, in this nationally representative study, adherence to the ‘GERMAS’ guideline may confer cardiometabolic health benefits to several groups of the Indonesian population, particularly men, middle-aged, those with overweight and obesity, and potentially urban population.

Patterns of six behaviors and psychosomatic symptoms in adolescents: A six-province study in China

BACKGROUND

Psychosomatic symptoms are often related with behaviors. However, the association between different behaviors and their latent patterns and psychosomatic health status is unclear. Current study aimed to identify the patterns of six behaviors and explore the association between different patterns and psychosomatic symptoms in a school-based sample of Chinese adolescents.

METHODS

From November 2015 to January 2016, the study enrolled 22,628 students from six cities in China (15.36 ± 1.79 years). Six behaviors [unintentional injury (UI), non-suicidal self-injury (NSSI), suicidal behaviors (SB), drinking, smoking, screen time (ST)] and psychosomatic symptoms (psychological and physical symptoms) were measured by self-report validated questionnaires.

RESULTS

Six behaviors were all related to psychosomatic symptoms, among which SB was the strongest. Four patterns of behaviors were be identified as follows: low-risk pattern (64.0%), substance use pattern (4.5%), injury pattern (28.8%) and high-risk pattern (2.7%). Logistic regression analysis of psychological symptoms indicated that compared with low-risk pattern, high-risk pattern had the highest risk, followed by injury pattern, substance use pattern showed the lowest risk. Compared with low-risk pattern, the results of physical symptoms suggested the degree of risk was high-risk pattern, injury pattern and substance use pattern, respectively.

LIMITATIONS

Cross-sectional data were used in the study that could not evaluate causal relationships between six behaviors and psychosomatic symptoms.

CONCLUSIONS

Six behaviors and their latent patterns are related to psychosomatic symptoms among Chinese adolescents differently, so different intervention and prevention protocol need to be taken for different patterns of adolescents.

Prevalence and correlates of multiple behavioural risk factors of non-communicable diseases among university students from 24 countries

BACKGROUND

Globally non-communicable diseases (NCDs) are on the increase. The goal of the study was to estimate the prevalence and correlates of multiple behavioural risk factors of NCDs among university students from 24 countries.

METHODS

In a cross-sectional study, the sample included 18 017 university students from countries in Africa, the Americas and Asia.

RESULTS

indicate that prevalence of single behavioural NCD risk indicators were 38.2% for physical inactivity, 80.5% for inadequate fruit and vegetables intake, 23.1% for having overweight/obesity, 10.5% for heavy alcohol use and 11.8% for current tobacco use. Students had on average 1.6 (SD = 0.9), and 15.9% had three or more behavioural NCD risk factors. In adjusted linear regression, male sex was positively and stronger beliefs in health benefits were negatively associated with multiple behavioural NCD risk factors.

CONCLUSIONS

A high prevalence and co-occurrence of behavioural risk factors of NCDs was discovered. Several behavioural NCD risk factors, such as male sex and low health behaviour benefits beliefs, were found that could be utilized in targeted interventions.

Polysubstance use among national samples of in-school adolescents in Tonga and Vanuatu

The study aimed to provide estimates on current polysubstance use among adolescents in Tonga and Vanuatu. Cross-sectional and national school health survey data were analyzed from 5028 adolescents (mean age 15.4 years) in Tonga and Vanuatu in 2016-2017. Polysubstance use was defined as currently using two or three substances of tobacco, alcohol, and cannabis. Results indicate that 72.9% of students reported zero current substance use, 14.5% single current substance use, and 12.6% current polysubstance use (2 or 3 types of substance use). In the adjusted multinational logistic regression analysis factors associated with current single and polysubstance included older adolescents (15-18 years or older), male sex, bullied, passive smoking, high psychological distress, and low peer support, whereby the associations with current polysubstance use were stronger than with current single substance use. In addition, parental tobacco use was associated with single substance use, and school truancy and frequent soft drink consumption (≥3 times/day) were associated with current polysubstance use, and high parental support was negatively associated with polysubstance use. More than one in ten of the participating students engaged in current polysubstance use. Several factors associated with current single and polysubstance use were found which can help in designing intervention strategies.

Multiple behavioural risk factors of non-communicable diseases among adolescents in four Caribbean countries: prevalence and correlates

OBJECTIVES

The study assessed the prevalence and associated factors of behavioural risk factors of non-communicable diseases (NCDs) among adolescents in four Caribbean countries.

CONTENT

In all 9,143 adolescents (15 years = median age) participated in the cross-sectional "2016 Dominican Republic, 2016 Suriname, 2017 Jamaica, and 2017 Trinidad and Tobago Global School-Based Student Health Survey (GSHS)". Eight behavioural risk factors of NCDs were assessed by a self-administered questionnaire.

SUMMARY

Prevalence of each behavioural NCD risk factor was physical inactivity (84.2%), inadequate fruit and vegetable intake (82.2%), leisure-time sedentary behaviour (49.6%), daily ≥2 soft drinks intake (46.8%), ever drunk (28.6%), twice or more days a week fast food consumption (27.6%), having overweight/obesity (27.4%), and current tobacco use (13.8%). Students had on average 3.6 (SD=1.4), and 79.0% had 3-8 behavioural NCD risk factors. In multivariable linear regression, psychological distress and older age increased the odds, and attending school and parental support decreased the odds of multiple behavioural NCD risk factors.

OUTLOOK

A high prevalence and co-occurrence of behavioural risk factors of NCDs was discovered and several factors independently contributing to multiple behavioural NCD risk factors were identified.

Ideal Cardiovascular Health Behaviours in Nationally Representative School-Based Samples of Adolescents in the Caribbean

Background

Ideal cardiovascular health behaviour (CVHB) measures four ideal health behaviours (non-smoking, body mass index <85th Percentile, healthy diet, and physical activity). This study aimed to determine the prevalence, distribution, and correlates of ideal CVHB among adolescents in the Caribbean.

Methods

Nationally representative cross-sectional data of 2016 or 2017 with complete CVHB measurements were analysed from 7556 school adolescents from four Caribbean countries.

Results

The prevalence of 0-1 ideal metrics CVHB was 20.4%, 2 ideal metrics 48.7%, and 3-4 ideal metrics 30.8%. Only 5.0% had all 4 ideal CVHB metrics, 41.0% intermediate CVH (≥1 metric in the intermediate category and none in the poor category), and 54.0% had poor CVH (≥1 metric in poor category). In adjusted logistic regression analysis, compared to students from Dominican Republic, students from Jamaica (Adjusted Odds Ratio-AOR: 1.36, 95% confidence interval-CI: 1.01-1.85), students from Trinidad and Tobago (AOR: 1.46, 95% CI: 1.17-1.82) and male sex (AOR: 1.35, 95% CI: 1.11-1.64) were positively associated with meeting 3-4 ideal CVHB metrics. In addition, in unadjusted analysis, rarely or sometimes experiencing hunger was negatively and high peer and parent support were positively associated with meeting 3-4 ideal CVHB metrics.

Conclusion

The proportion of meeting 3-4 ideal CVHB metrics was low among adolescents in four Caribbean countries. Both high-risk and school-wide intervention programmes should be implemented in aiding to improve CVHB in Caribbean countries. Several factors associated with ideal CVHB were identified, which can be targeted in school health interventions.

Noncommunicable Disease Risk Factors Among Adolescent Boys and Girls in Bangladesh: Evidence From a National Survey

Objectives

To assess the prevalence of noncommunicable disease (NCD) risk factors and the factors associated with the coexistence of multiple risk factors (≥ 2 risk factors) among adolescent boys and girls in Bangladesh.

Methods

Data on selected NCD risk factors collected from face to face interviews of 4,907 boys and 4,865 girls in the national Nutrition Surveillance round 2018-2019, was used. Descriptive analysis and multivariable logistic regression were performed.

Results

The prevalence of insufficient fruit and vegetable intake, inadequate physical activity, tobacco use, and being overweight/obese was 90.72%, 29.03%, 4.57%, and 6.04%, respectively among boys; and 94.32%, 50.33%, 0.43%, and 8.03%, respectively among girls. Multiple risk factors were present among 34.87% of boys and 51.74% of girls. Younger age (p < 0.001), non-slum urban (p < 0.001) and slum residence (p < 0.001), higher paternal education (p = 0.001), and depression (p < 0.001) were associated with the coexistence of multiple risk factors in both boys and girls. Additionally, higher maternal education (p < 0.001) and richest wealth quintile (p = 0.023) were associated with the coexistence of multiple risk factors in girls.

Conclusion

The government should integrate specific services into the existing health and non-health programs which are aimed at reducing the burden of NCD risk factors.

Tobacco Use and Its Association with Mental Morbidity and Health Compromising Behaviours in Adolescents in Indonesia

Background:

Limited evidence has been established on associations between tobacco use and mental morbidity and health compromising behaviours. The study aimed to investigate the associations between tobacco use, mental problems, and health risk behaviour among adolescents attending school in Indonesia. Methods: Nationally representative data were studied from 11,124 adolescents that took part in the cross-sectional “Indonesia Global School-Based Student Health Survey (GSHS) in 2015”.

Results:

The prevalence of current tobacco use was 12.8%. In adjusted logistic regression analysis, compared to non-current or never tobacco users, current tobacco use was associated with eight of eight mental problem indicators (lonely, anxiety, no close friend, suicidal ideation, suicide plan, suicide attempt and current alcohol use), two of four dietary risk behaviours (soft drink and fast food consumption) and seven of ten other health risk behaviours (in a physical fight, bullied, injury, ever sex, school truancy, and two sub-optimal hand hygiene behaviours).

Conclusion:

Compared to nontobacco users, current tobacco users had significantly higher mental problem indicators and health risk behaviours. Multiple comorbidity with tobacco use should be targeted in interventions.

Insights Into Adolescents' Substance Use in a Low-Middle-Income Country During the COVID-19 Pandemic

Introduction: The COVID-19 pandemic and its lockdown have been a significant life event for many individuals, particularly adolescents. The immense psychological pressure could drive risky behavior, e.g., substance use, while lockdown might lead to decreased use. This study aimed to observe the change in substance use among adolescents in Indonesia and the moderating variables to consumption during the COVID-19 lockdown period. Methods: This study utilized an online survey from April 28, 2020 to June 30, 2020. The hyperlink was disseminated to school administrators and parenting groups through social media and direct messages. A total of 2,932 adolescents (17.4 ± 2.24 and 78.7% females) submitted valid responses. The survey was comprised of a sociodemographic section, substance use details, and psychometric sections, including the Alcohol Use Disorders Identification Test (AUDIT), Cigarette Dependence Scale 12 (CDS-12), Pittsburgh Sleep Quality Index (PSQI), and Strength and Difficulties Questionnaire (SDQ). Results: Overall, adolescent alcohol use during the pandemic was 5.1%, cigarette smoking was 3.1%, and drug consumption was 0.4%. Over half (53.4%) of alcohol drinkers reported increased drinking, and 33.1% had harmful or dependence-like drinking behavior; in contrast, 44.4% of adolescent smokers disclosed reduced cigarette consumption. Around 37.8% of the drug users indicated increased use. During the pandemic, adolescent alcohol use was associated with higher education [adjusted odds ratio (AOR) = 2.67, 95% confidence interval (CI) 1.02-4.86, p = 0.04], higher AUDIT scores (AOR = 1.33, 95% CI 1.25-1.42, p < 0.001), and very low prosocial behavior (AOR = 2.46, 95% CI 1.52-3.88, p < 0.001). Cigarette smoking was correlated with male sex (AOR = 9.56, 95% CI 5.64-16.62, p < 0.001), age (AOR = 1.40, 95% CI 1.14-1.75, p < 0.001), and higher CDS score (AOR = 1.17, 95% CI 1.13-1.20, p < 0.001). Conclusions: Rates of adolescent substance use were significant, with sizeable proportions reporting higher usage. This appeared to occur predominantly in specific demographics and those with a lower protective psychosocial attribute, i.e., prosocial behavior, during the lockdown. These findings should urge the strengthening of adolescent addiction care during and after the pandemic.

Physical Activity and Sedentary Behavior Research in Indonesian Youth: A Scoping Review

BACKGROUND

This study aimed to map physical activity and sedentary behaviour research trends, designs, and topics for Indonesian youth.

METHODS

This review conforms to the "Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR)." A systematic search on eight platforms was performed in August 2018 and was updated in April 2020.

RESULTS

From 10,753 documents screened, 166 met the selection criteria. Over half of the studies were cross-sectional, and the majority utilized self-reported measurements (physical activity: 81.1%, sedentary behavior: 88.5%). More than two-thirds of the studies examined physical activity only (67.5%). The top three subtopics reported were prevalence/measurement, correlates, and outcomes of physical activity (28%, 24.6%, and 17%, respectively). The prevalence of "sufficient" physical activity ranges between 12.2% and 52.3%, while the prevalence of sedentary behavior ≥3 h per day ranges between 24.5% and 33.8%.

CONCLUSIONS

Future studies need to focus more on intervention and validation, and research needs to be conducted more with nationally representative samples and on youth at the junior high school level. Future studies need to investigate more on psychological, cognitive, affective, social, cultural, and environmental correlates, and in-depth personal views of physical activity and sedentary behavior. More studies using device-based measurements, longitudinal designs, as well as qualitative and mixed-methods approaches are warranted.
