Kuwait has one of the highest obesity rates in the world. This study examined the associations between sedentary behaviour (objectively measured and self-reported), adiposity and systolic blood pressure in a sample of adolescents residing in Kuwait. Data was obtained from the Study of Health and Activity among adolescents in Kuwait (2012-2013). The sample included a total of 435 adolescents (201 boys). Outcomes were age- and sex specific body mass index Z-scores and systolic blood pressure. Exposures were total sedentary behaviour measured by accelerometry and time spent in some sedentary behaviours (television viewing, video games, computer use and total screen-time). We used multiple linear regression analyses, adjusted for age, governorate, maternal education and physical activity, to examine associations between sedentary behaviour and adiposity and systolic blood pressure.
Only 2 statistically significant associations were found between sedentary behaviour and the study outcomes: body mass in boys was directly associated with higher sedentary time [β (95% CIs) 0.003 (0.00 to 0.06)]; body mass index was inversely associated with videogames in both sexes [girls: β (95% CIs) - 0.17 (- 0.48 to - 0.04); boys: - 0.24 (- 0.57 to - 0.12)]. In this sample of Kuwaiti adolescents, sedentary behaviour showed limited deleterious associations with adiposity and systolic blood pressure.
科威特是世界上肥胖率最高的国家之一。本研究调查了科威特青少年样本中久坐行为（客观测量和自我报告）、肥胖与收缩压之间的关联。数据来自科威特青少年健康与活动研究（2012 - 2013年）。样本共包括435名青少年（201名男孩）。结局指标为年龄和性别特异性的体重指数Z评分和收缩压。暴露因素为通过加速度计测量的总久坐行为以及在某些久坐行为（看电视、玩电子游戏、使用电脑和总屏幕时间）上花费的时间。我们使用多元线性回归分析，对年龄、省份、母亲教育程度和体育活动进行了调整，以研究久坐行为与肥胖及收缩压之间的关联。
在久坐行为与研究结局之间仅发现2个具有统计学意义的关联：男孩的体重与较长的久坐时间直接相关[β（95%置信区间）0.003（0.00至0.06）]；男女两性的体重指数均与玩电子游戏呈负相关[女孩：β（95%置信区间）-0.17（-0.48至-0.04）；男孩：-0.24（-0.57至-0.12）]。在这个科威特青少年样本中，久坐行为与肥胖及收缩压之间的有害关联有限。
