Objectives: Lowering the prevalence of mental health illness is one of the main public health concerns. The objective of the present study was to examine factors associated with depression and generalized anxiety disorder (GAD) among adults in Malaysia. Methods: Data were extracted from the National Health and Morbidity Survey 2011 (NHMS 2011), which is a nationally representative sample collected using a 2-stage stratified sampling method. A bivariate probit model was utilized to examine the influences of sociodemographic, lifestyle, and health factors on the likelihood of suffering from depression and GAD. Results: Age, gender, ethnicity, education, marital status, and self-rated health were significantly associated with depression and GAD. In particular, there were positive relationships between depression and GAD, and younger adults, females, Indian ethnic group, lower level of education, being unmarried, and self-rated poor health. Conclusions: Sociodemographic and health factors were associated with determining the risks of depression and GAD in Malaysia. With this information, future policies (eg, screening and treatment) could be targeted at those at most risk to develop depression and GAD.

Estimating the factors affecting participation decisions of physical activity has continuously received significant research attention. However, the effects of income and demographic factors on physical activity intensity have seldom been studied thoroughly, especially in developing countries. To fill this research gap, the income and demographic determinants of the time spent on both vigorous- and moderate-intense physical activities among Malaysian adults are estimated using a censored regression model. The results are comparable to those in developed countries, such as the USA and Australia, which show that income, age, education level and being unemployed are negatively associated with the time spent on both vigorous- and moderate-intense physical activities. Compared to females, males spend more time on vigorous-intense physical activity but less time on moderate-intense physical activity. The present study suggests that acquiring a better understanding of the factors that can affect physical activity intensity is important for policy development. JEL Classification: D01, I10, I12

Background: Depression is a serious mental health illness worldwide. The purpose of the study was to investigate the relationships between depression and its risk factors of sociodemography, lifestyle, and health among the adults of the different ethnic groups in Malaysia. Method: A nationwide database with 10141 observations was used. Multivariable logistic regression analyses stratified by ethnicity were estimated. Results: Ethnicity and gender, age, education, marital status and self-rated health were correlated to the likelihood of having depression. Malay females and smokers (AOR: 2.083) were more likely to suffer from depression than Malay males (AOR: 0.305) and non-smokers. Higher-income Chinese displayed higher odds of having depression than lower-income Chinese (AOR: 1.009). Indians and others with secondary-level education displayed a lower likelihood of developing depression compared to those with primary-level education (AOR: 0.587). Conclusion: This study could contribute significantly to the formulation and development of an effective policy directed towards reducing the prevalence of depression in the vulnerable. These were the adults, in the younger age group, with lower education, with self-rated poor health, being female, unmarried, Malay and Chinese, and Indians and others. A nationwide policy targeted towards the Malay females to reduce their depression, with attention to the Chinese with a high income, and to the Indians and others with poor educational background to improve their knowledge of mental health, would be worthy of consideration.
