Current dietary supplement (DS) use among Saudi school students is not well described. In this study, we aim to investigate the prevalence and predictors of DS use among adolescents. This cross-sectional study collected data via self-administered questionnaire from 1221 students (12 to 18 years). The overall prevalence of DS use was 26.2%, significantly higher in females than males (33% vs. 17.9%, < 0.001). High proportion of female DS users demonstrated normal BMI than males (84% vs. 56.5%, < 0.001). High percentage of male DS users were engaged in vigorous and/or high physical activity (PA) levels than female DS users (58.2% vs. 43%, = 0.022; and 57.1% vs. 20.7%, < 0.001, respectively). The main reasons for DS use among females were vitamin deficiency (63.3%), hair condition (37.6%) and nail health (23.5%) while in males, the main reasons were vitamin deficiency (58.4%) and body building (34.4%). The predictors of DS use in Saudi adolescents included being female, having high family income and being physically active. In conclusion, the overall prevalence and preference of DS use, though low among Saudi adolescents, was driven mostly by gender, physical activity levels and socioeconomic factors like family income. DS use guidelines and counselling among Saudi adolescents are warranted to improve public health.
目前沙特学生的膳食补充剂（DS）使用情况尚未得到充分描述。本研究旨在调查青少年 DS 使用的流行率及其预测因素。这项横断面研究通过自填式问卷收集了 1221 名学生（12 至 18 岁）的数据。DS 使用的总体流行率为 26.2%，女性显著高于男性（33%比 17.9%，<0.001）。高比例的女性 DS 用户的 BMI 正常，而男性则不然（84%比 56.5%，<0.001）。与女性 DS 用户相比，更多的男性 DS 用户从事剧烈和/或高强度的体力活动（PA）（58.2%比 43%，=0.022；57.1%比 20.7%，<0.001）。女性使用 DS 的主要原因是维生素缺乏（63.3%）、头发状况（37.6%）和指甲健康（23.5%），而男性的主要原因是维生素缺乏（58.4%）和健身（34.4%）。沙特青少年使用 DS 的预测因素包括女性、高家庭收入和体力活动。总之，尽管沙特青少年的 DS 使用总体流行率和偏好率较低，但主要受性别、体力活动水平和家庭收入等社会经济因素的驱动。有必要在沙特青少年中开展 DS 使用指南和咨询服务，以改善公共卫生。
