Therefore, this study aims to identify the prevalence of geriatric depressive disorders and their risk factors in a large-scale study comprising community-dwelling older adults in Malaysia. Methods A total of 2264 older adults consisting of 1083 (47.8%) men and 1181 (52.2%) women were recruited in this study. An interview-based questionnaire was used to obtain information on sociodemography, presence of comorbidities, nutritional status, dietary habits, lifestyle, practice of calorie restriction, cognitive function, social support, and psychosocial aspects. Geriatric depressive disorder was confirmed if a participant obtained a score of 5 or more in the Geriatric Depressive Scale. Results The prevalence of depressive symptoms is 16.5%, and it is higher in women (56.6%) than in men (43.4%). Individuals who are at a higher risk of depressive disorders are most likely to be less educated and to have neurotic disorder, a lower score of instrumental activities of daily living , poor fitness level, hypertension, and osteoarthritis.
