Few studies have reported comprehensive and valid physical activity (PA) data for Saudi youth. Therefore, the purpose of this study was to examine patterns and determinants of PA among Saudi adolescents.
A cross-sectional study was conducted in Saudi secondary schools (15-19 years) during 2009/2010 and used multistage stratified cluster sample (N = 2866, 51.7% females). Weight, height, sedentary behaviors, PA, and dietary habits were assessed.
Roughly 44% of males and 20% of females were active (≥ 1 hour/day). Males in public schools were more active than in private schools, whereas the opposite was true for females. Females exercise mostly at home, whereas males exercise at public places. The majority of females exercise alone or with relatives, whereas males largely exercise with friends. Males were active for health and recreation whereas females were active for weight loss and recreation. Lack of time was the primary reason for inactivity in both sexes. The predictors of total PA time were gender, intakes of fruit, milk, energy drinks and vegetables and waist/height ratio (R2 = 0.145).
The high inactivity levels, especially among females, are of great concern. Promotion of active living among youth should be a national public health priority.
很少有研究报告沙特青年全面且有效的身体活动（PA）数据。因此，本研究的目的是调查沙特青少年身体活动的模式和决定因素。
2009/2010年在沙特中学（15 - 19岁）进行了一项横断面研究，采用多阶段分层整群抽样（N = 2866，51.7%为女性）。评估了体重、身高、久坐行为、身体活动和饮食习惯。
大约44%的男性和20%的女性身体活动活跃（≥1小时/天）。公立学校的男性比私立学校的男性更活跃，而女性情况则相反。女性大多在家锻炼，而男性在公共场所锻炼。大多数女性独自或与亲属一起锻炼，而男性主要与朋友一起锻炼。男性为了健康和娱乐而进行身体活动，而女性则为了减肥和娱乐而进行身体活动。缺乏时间是两性不活动的主要原因。总身体活动时间的预测因素是性别、水果、牛奶、能量饮料和蔬菜的摄入量以及腰高比（R2 = 0.145）。
身体活动不活跃水平较高，尤其是在女性中，令人高度关注。促进青少年积极生活应成为国家公共卫生的优先事项。
