Abstract
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.
