Anxiety is burdensome and common in youth. Sedentary behaviour has been identified as potentially modifiable dangerous factors for many diseases. Nevertheless, little is known about the relationship between sedentary behaviour and the risk of anxiety symptoms in youth. Therefore, we aimed to examine the association among youth in 24 low- and middle-income countries (LMICs).
Data from the Global School-based Student Health Survey (GSHS) were analyzed in 59587 youth aged 12-15 years. Most of the country-wide data were nationally representative. Anxiety symptoms were self-reported. Multivariable logistic regression and meta-analyses of country-wise estimates were conducted.
The prevalence of anxiety symptoms was 10.3%. Countrywide meta-analysis demonstrated that sedentary behaviour of >2 h/day (vs.≤2 h/day) was associated with an increased risk of anxiety symptoms (OR = 1.22; 95% CI = 1.10-1.37).
This study provides multi-national evidence of the dangerous effect of sedentary behaviour against anxiety symptoms among youth in LMICs. Decreasing the level of sedentary behaviour during adolescence could be an important target for reducing the prevalence of anxiety.
焦虑在年轻人中普遍存在且负担沉重。久坐行为已被确定为许多疾病的潜在可改变的危险因素。然而，对于久坐行为与年轻人焦虑症状风险之间的关系知之甚少。因此，我们旨在研究 24 个中低收入国家（LMICs）的年轻人之间的关系。
对年龄在 12-15 岁的 59587 名年轻人进行了全球基于学校的学生健康调查（GSHS）的数据分析。大多数全国范围内的数据具有全国代表性。焦虑症状是自我报告的。对国家估计值进行了多变量逻辑回归和荟萃分析。
焦虑症状的患病率为 10.3%。全国范围内的荟萃分析表明，每天久坐行为超过 2 小时（与每天≤2 小时相比）与焦虑症状的风险增加有关（OR=1.22；95%CI=1.10-1.37）。
本研究提供了多国家的证据，证明了久坐行为对中低收入国家年轻人焦虑症状的危险影响。减少青少年时期的久坐行为水平可能是降低焦虑症患病率的一个重要目标。
