: Being overweight at a young age is a predictor of developing obesity and related complications later in adulthood, posing a high risk to public health. Various ethnic subgroups have been identified as having a higher prevalence of overweight or obese. Saudi Arabia is one of the fastest-growing economies in the world, where the expatriate population comprises 33% of its total population. The objective of this study was to investigate differences in body composition indices, sitting time associated with media use, and physical activity pattern among a sample of local and expatriate school students in Saudi Arabia. : 500 students (aged 8-18 years) from various schools were invited to participate in this study. Body weight, waist circumference (WC) and height were measured using a portable digital metric scale, standard measuring tape and wall mounted tape respectively. Participants and their parents were jointly asked to report the average time that the participant spent sitting using media (watching TV, playing video games, and using the internet and other screen-based devices etc.) per day. The pattern of physical activity among participants was measured using a short form of the International Physical Activity Questionnaire (IPAQ). Basal metabolic rate (BMR) and total daily energy expenditure (TEE) were estimated from body weight, height, age, sex and physical activity, according to the Harris-Benedict equation. : Data from 450 (90%) of the participants were used for analysis. The mean age of the participants was 14.55 ± 1.74 years. Body mass index (BMI), WC, waist to height ratio (WHtR), BMR and TEE differed significantly among the participants. Physical fitness score negatively correlated with BMI and WC, while sitting time associated with media use positively correlated with BMI, WC, WHtR and physical fitness score, among both Saudi and expatriate participants. : Body composition indices and sitting time associated with media use were higher among Saudi boys and expatriate girls. Expatriate boys and girls were reported to be physically more active than their Saudi counterparts. BMR and TEE were higher among expatriate boys and Saudi girls. Although this study provides useful information about the association of body composition indices, sitting time associated with media use, and physical activity pattern among local and expatriate school students in SA, similar studies involving a larger study sample, with equal gender representation, are further required to determine various factors associated with this link.
: 年轻时超重是成年后患肥胖症和相关并发症的预测因素，对公众健康构成高度风险。已经确定了各种族群体超重或肥胖的患病率较高。沙特阿拉伯是世界上增长最快的经济体之一，其外籍人口占总人口的 33%。本研究的目的是调查沙特阿拉伯当地和外籍学生样本中身体成分指数、与媒体使用相关的坐姿时间和体育活动模式的差异。: 邀请了来自不同学校的 500 名学生（年龄在 8-18 岁之间）参加这项研究。使用便携式数字秤、标准卷尺和壁挂式卷尺分别测量体重、腰围 (WC) 和身高。参与者及其父母被共同要求报告参与者每天平均花在使用媒体（看电视、玩电子游戏、使用互联网和其他基于屏幕的设备等）上的时间。参与者的体育活动模式使用国际体力活动问卷 (IPAQ) 的简短形式进行测量。根据哈里斯-本尼迪克特方程，从体重、身高、年龄、性别和体力活动中估计基础代谢率 (BMR) 和总每日能量消耗 (TEE)。: 对 450 名（90%）参与者的数据进行了分析。参与者的平均年龄为 14.55 ± 1.74 岁。BMI、WC、腰高比 (WHtR)、BMR 和 TEE 之间存在显著差异。身体适应性得分与 BMI 和 WC 呈负相关，而与媒体使用相关的坐姿时间与 BMI、WC、WHtR 和身体适应性得分呈正相关，无论是沙特参与者还是外籍参与者都是如此。: 沙特男孩和外籍女孩的身体成分指数和与媒体使用相关的坐姿时间较高。与沙特人相比，外籍男孩和女孩的身体活动量更高。BMR 和 TEE 在外籍男孩和沙特女孩中更高。尽管这项研究提供了有关 SA 当地和外籍学生身体成分指数、与媒体使用相关的坐姿时间和体育活动模式之间关联的有用信息，但还需要进一步进行涉及更大研究样本、性别平等代表性的类似研究，以确定与这一联系相关的各种因素。
