Factors Associated to Dietary Supplement Consumption Behavior among Undergraduate Students in the Central Part of Thailand; A Cross-sectional Study

— The dietary supplement is a good short cut solution to get adequate amounts of essential nutrients and better quality of health. The aim of this study was to investigate the associated factors of dietary supplement consumption behavior among undergraduate students in the central part of Thailand. This study was a crosssectional study surveying 218 undergraduate students aged 18-24 years old in the university between June and October 2019 by multistage random sampling. The data were collected using the structured interview and medical record consisted of 4 parts. Data were analyzed by using descriptive statistics and Pearson correlation coefficient. The result showed that the majority samples had a high level of dietary supplement consumption behavior (55.5%), followed by moderate and low level of and dietary supplement consumption behavior (43.6% and 0.9%, respectively). Moreover, the result reveled that the factors which remained significantly associated with dietary supplement consumption behavior were monthly income (r = 0.133, p= 0.049), attitude about dietary supplement consumption (r = 0.291, p< 0.001) and social support (r = 0.309, p< 0.001). The finding suggests that the university administrators in the central part of Thailand should focus on associated factors to plan and impose a policy or guidance for changing the appropriate behavior of dietary supplement in the students.
