The aim of this study was to investigate the usage of dietary supplements by the elderly in Taiwan and sought to find out the predictors of usage and beginning of usage. Data from the panel study of the physical health, mental health and social activities of elderly people in Taiwan was collected. Data from 2506 participants who were enrolled in both 1999 and 2007 was available. We obtained the data of demographics, healthy state and health lifestyle from questionnaire. Multiple logistic regression was used to determine predictors of supplements usage in this cohort. People who are female, with high education, higher economic satisfaction, in worse health state, or better health lifestyle are more likely to use dietary supplements.
