Literature on Generalized Anxiety Disorder (GAD) and its impact has consistently focused on not only comorbidities but also homogenous and small populations. The aims of this study were to determine the prevalence and trends of primary GAD in a nation wide population based study in Malaysia. A cross-sectional survey was conducted using Mini International Neuropsychiatric Interview Version 5.0.0 (MINI) to ascertain GAD status of subjects. All Malaysian aged 16 years and above were eligible to participate from each of the house holds selected. Face to face interview was conducted. A total of 19193 participants were identified with 330 participants having primary GAD, thus giving the prevalence of primary GAD as 1.7%. Multivariable logistic regression analysis revealed that age groups of 16-19 and 20-29 years were more likely to have primary GAD compared to those more than 60 years of age. Chinese participants were less likely to have primary GAD compared to Malay participants. Indian participants were more likely to have primary GAD compared to Malay participants. Single participants were more likely to have primary GAD compared to married participants while widow/widower/divorcee were more likely to have primary GAD compared to married participants. Those who were in the private sector, being self-employed, being a home maker/unpaid worker and retirees were more likely to have primary GAD compared to government/semi government participants. Multivariate analysis showed that gender, ethnicity and occupation were significantly associated with primary GAD.

Diabetes mellitus is an important cardiovascular risk factor. The objective of this study was to provide population-based estimates on the prevalence, awareness, treatment and control rate of diabetes among the older persons in Malaysia. Analysis of secondary data from a cross-sectional national population-based survey was done, which was conducted in 2011 throughout Malaysia. A total of 2764 respondents (15.5%) were older persons. The overall prevalence of diabetes among older persons was 34.4% in which 65.2% were aware of their diabetes status. Out of those who were aware, 87.5% had been treated. Only 21.8% of those treated had their diabetes controlled. The results of multiple logistic regression showed that the factors associated with higher awareness rates were women, Indians and higher income groups; factors associated with higher treatment rates were urban residents and those who were married and widow/widower/ divorcee. There was a high overall prevalence, awareness and treatment rate of diabetes among older persons in Malaysia but with suboptimal control rate.
