Background: Depression is on the rise and has become a significant concern for public health. Limited research has explored the connection between dietary patterns and depression. This investigation aimed to examine how dietary behaviours relate to depression among adolescents attending school in Malaysia. Methods: The study utilized data from the National School-Based Health Survey 2022, a nationwide survey involving school-going adolescents aged 13–17, with a total of 33,523 participants from 239 schools. To assess depression, the study employed the Patient Health Questionnaire (PHQ-9), considering a score of 10 or higher as indicative of depression. Dietary behaviours were assessed using a validated self-administered questionnaire adapted from the World Health Organization's Global School-based Student Health Survey. Descriptive analysis and complex sample logistic regression were carried out using SPSS version 26.0. Results: The study revealed a 26.9% overall prevalence of depression, with higher risks among female adolescents (AOR 2.71, 95% CI 2.51, 2.92) and those in higher grades. Malays (AOR 1.71, 95% CI 1.41, 2.07), Other Bumiputeras (AOR 1.69, 95% CI 1.32, 2.17), and Others (AOR 1.63, 95% CI 1.16, 2.30) had elevated odds of depression compared to Indians. Healthy dietary habits, like consuming less than two servings of fruits daily, correlated with depression (AOR 1.44 95% CI 1.35, 1.54). Additionally, unhealthy dietary behaviours such as fast food consumption (AOR 1.73 [95% CI 1.55, 1.93]) and carbonated soft drink intake (AOR 1.59 [95% CI 1.48, 1.70]) were positively associated with depression. Conclusions: One out of every four Malaysian adolescents was identified to experience depression. Depression was linked to several factors, such as being female, belonging to higher grade levels, identifying as Malays, Other Bumiputeras, or belonging to other ethnicities, and participating in the consumption of fast food, carbonated soft drinks, and fruits. To address these observations, it is crucial to formulate effective public health programmes that prioritize adolescent mental health and encourage the adoption of healthy eating habits.

The aim of the study was to evaluate the effectiveness of a school-based intervention programme among overweight and obese adolescents in Seremban, Negeri Sembilan, Malaysia. A cluster randomised controlled trial was conducted to evaluate the effect of the intervention (n = 200) and compared with control group (n = 200). The intervention was developed based on social cognitive theory, conducted in a group based, five-session of face-to-face, bi-weekly for 10 weeks. The primary outcomes were body mass index (BMI) and BMI-for-age z-scores (BAZ), whereas the secondary outcomes were breakfast consumption, physical activity level, self efficacy, and body satisfaction. T-tests and generalized linear mixed model analysis were used to examine the effectiveness of the intervention at baseline, immediate post-intervention, and 3-month post-intervention, while controlling for covariates. A significant intervention effect was found in reducing BMI and BAZ. BMI of the participants in the intervention group was reduced from 28.10 kg/m2 to 27.93 kg/m2, and further decreased to 27.80 kg/m2, while BAZ was reduced from 2.19 to 2.12, and further decreased to 2.07, from baseline to immediate post-intervention, and 3-month follow-up, respectively. Furthermore, there was significant improvement in breakfast consumption frequency, physical activity scores, healthy eating and weight self-efficacy scores, perceived physical activity self-efficacy scores, and body discrepancy scores as compared with the control group. The integrated school-based intervention programme was effective in reducing BMI and BAZ among overweight and obese participants. The results suggested that this programme could be integrated as one of the regular school co-curricular programmes.

Introduction: Obesity is recognized as a serious public health threat. Recent evidence has warned of the alarming rise in the prevalence of childhood overweight and obesity throughout the world. This study aimed to determine the prevalence of overweight and obesity, and its associations with socio-demographic, behavioral, and psychosocial factors among school-going adolescents in Seremban, Negeri Sembilan. Methods: Cross-sectional study was conducted. A total of 2,221 adolescents were randomly selected from eight secondary schools. A questionnaire was administered to assess socio-demographic profiles, meal patterns, physical activity level, self-efficacy, self-esteem, body size satisfaction, perception of body weight status, depression, anxiety, stress, and nutrition knowledge. Bodyweight and height were measured and BMI-for-age z scores were computed to determine the body weight status. Bivariate analysis and multivariate logistic regression were used for the data analysis. Results: The prevalence of overweight among the participants in this study was 17.0%, while the prevalence of obesity was 14.9%. The significant predictors of overweight and obesity in this study were breakfast skipping, low physical activity level, low self-efficacy scores in terms of healthy eating, weight and physical activity, body dissatisfaction, and perception of large body size. Conclusion: The results emphasize the need to broaden the scope of nutrition guidelines, public health policies, and programs to address overweight and obesity among adolescents in Malaysia. The findings also suggest that health education programs should cover practical advice for modifying healthy eating behaviors, increasing physical activity, as well as matters on body image and body satisfaction.

In 2016, World Health Organization (WHO) estimated more than 650 million obese adults, resulting in a country’s health burden. This study aims to determine the prevalence of obesity and its associated factors among Malaysian adults. A total of 5820 respondents, aged 18 to 59 years, from the National Health and Morbidity Survey 2019, were included for the data analysis. The prevalence of obesity was described and multivariate analyses were conducted to determine the factors associated with obesity. The prevalence of obesity among Malaysian adults was 20.1%, based on the findings from this study. Multivariate analyses showed that women, being Malays, Indians, and other Bumiputeras, were significantly associated with a higher risk of obesity. Besides, those diagnosed with diabetes mellitus and hypertension were also significantly associated with greater risk of obesity. This information is crucial for policy makers in formulating effective strategies or targeted programs in preventing obesity among Malaysian adults.
