Objective: Depression is the single largest contributor to the global burden of disease. Depression was found as a common disorder among children lower than 18 years old. The aim of this study is to determine the prevalence and factors associated with depression severity among adolescents in Malaysia. Study design: A cross-sectional study. Methods: In order to achieve the objective of this study, secondary data analysis from Malaysian National School Based Health Survey 2012 was carried out, involving a total of number of 21,764 eligible school adolescents between the ages of 12 to 18 years old. Additionally, complex sample ordinal logistic regression was also employed for analysing and quantifying the odds ratio, in which 95% confidence interval was achieved. Results and Discussion: This study discovered that the prevalence of mild, moderate and severe depression was 16.6%, 12.8% and 3.8% respectively. The result of the multivariable analysis showed that females have 32% more risk in having more severe depression as compared to males. Indians ethnics have 73% higher odds in developing more severe depression as compared to Malays. Those who were smoker and drink alcohol have 30% higher risk in having more severe depression as compared to non-smoker and who do not drink alcohol. Adolescent who ever used drug had 81% higher chance in having more severe depression as compared to those who never used drug. Adolescent who ever had suicidal ideation had 3-time greater chance in having more severe depression as compared to whom don’t. Adolescent who involved in truancy activity had 31% higher chance in having more severe depression as compared to those who didn’t. Adolescent who ever being bullied had 84% higher chance in having more severe depression as compared to those who never been bullied. Adolescent who have parent or guardian never or rarely know what they were doing had 33% greater risk in having more severe depression as compared to who have parent or guardian know what they do. Lastly, adolescent who have parent or guardian never or rarely understand what their problems and worries had 29% greater risk in having more severe depression as compared to who have parent or guardian understand their problems and worries. Conclusion: The submission of this study is that there is need for prevention and intervention programs, which must be designed and targeted towards adolescents who are exposed to various risks identified in this study.

High blood pressure is a worldwide problem and major global health burden. Whether alone or combined with other metabolic diseases, high blood pressure increases the risk of cardiovascular disease. This study is a secondary data analysis from the National Health and Morbidity Survey 2015, a population-based study that was conducted nationwide in Malaysia using a multi-stage stratified cluster sampling design. A total of 15,738 adults ≥18-years-old were recruited into the study, which reports the prevalence of hypertension stages among adults in Malaysia using the JNC7 criteria and determinants of its severity. The overall prevalence of raised blood pressure was 66.8%, with 45.8% having prehypertension, 15.1% having Stage 1 hypertension, and 5.9% having Stage 2 hypertension. In the multivariate analysis, a higher likelihood of having prehypertension was observed among respondents with advancing age, males (OR = 2.74, 95% CI: 2.41–3.12), Malay ethnicity (OR = 1.21, 95% CI: 1.02–1.44), lower socioeconomic status, and excessive weight. The factors associated with clinical hypertension (Stages 1 and 2) were older age, rural residency (Stage 1 OR = 1.22, Stage 2 OR = 1.28), Malay ethnicity (Stage 2 OR = 1.64), diabetes (Stage 2 OR = 1.47), hypercholesterolemia (Stage 1 OR = 1.34, Stage 2 OR = 1.82), being overweight (Stage 1 OR = 2.86, Stage 2 OR = 3.44), obesity (Stage 1 OR = 9.01, Stage 2 OR = 13.72), and lower socioeconomic status. Almost 70% of Malaysian adults are at a risk of elevated blood pressure. The highest prevalence was in the prehypertension group, which clearly predicts a future incurable burden of the disease. Public health awareness, campaigns through mass and social media, and intervention in the work place should be a priority to control this epidemic.
