RESUMO
The use of dietary supplements (DS) is increasing worldwide, however, there are limited studies examining the characteristics of people who take supplements in the United Arab Emirates. To examine the use of DS and their association with sociodemographic/lifestyle factors among college students in the UAE. A cross-sectional study conducted on 452 (18 to 24 years) college students (247 females and 205 males). A self-administered questionnaire that included sociodemographic and lifestyle characteristics, DS use, attitudes, and behavior was used. The prevalence of DS users was 35.6%. Dietary supplement use was significantly more among males than females (P = 0.008). The males preferred protein supplements (29.4%), while females consumed multivitamin and mineral supplements. Dietary supplement use was related to physical activity and the existence of a health problem. Males took DS for medical needs and to increase their muscle mass while females took them for medical needs (P = 0.001). While there a was significant difference between DS users and non-users related to knowledge (P = 0.000). The majority of DS users agreed that supplements are essential for health (68.3%) and only 39.8% agreed it was safe to use. Dietary supplement users source of information was health care providers (30.5%) followed by social media (22.2%). The prevalence of supplement use among college students was moderate among college students in the UAE. The results draw the attention for increasing public awareness about the DS appropriate use and safety from reliable sources so they could make more informed choices.
