A 50-item survey on DSs was administered to 8012 participants from March to May 2019. The usage rate of total DSs was 71.3% and 57.7% on imported DSs (IDSs). Approximately 53.7% of participants bought IDSs, and the most frequently used was vitamins (83.2%). The largest source of imported IDSs was the United States (55.8%). Multivariate analysis showed that more developed areas, women, those with a higher educational background, those with higher incomes, and those categorized as workers and staff members and retirees were more likely to have taken DSs. © 2022 Wolters Kluwer Health, Inc.
