          Abstract

          Objective To investigate the relationship among physical activity, sleep duration and screen time and overweight and obesity among children and adolescents in Beijing-Tianjin-Hebei region, and to provide reference for children and adolescents in Beijing-Tianjin-Hebei region to maintain healthy physique.

          Methods In November 2019, 4 262 primary and secondary school students in Beijing-Tianjin-Hebei region were surveyed on physical activity, sleep status and screen time according to the physical activity guidelines for children and adolescents, and the relationship between overweight and obesity was analyzed by Logistic regression.

          Results The prevalence of overweight and obesity among children and adolescents in Beijing-Tianjin-Hebei region was 22.03%. The positive rate of overweight was 12.01% and obesity was 10.02%. The prevalence of overweight and obesity in male students (26.09%) was higher than that in female students (17.88%), the difference was statistically significant (χ 2=41.77, P<0.01). The prevalence of overweight and obesity in urban children (24.09%) and Han children (22.74%) was significantly higher than that in rural areas (21.05%) and ethnic minorities (17.70%) (χ 2=5.00, 7.63, P<0.05). The proportion of children who met physical activity, screen time and sleep duration guideline was 24.85%, 38.69% and 57.09%, respectively. A total of 21.68% of children and adolescents did not meet the guideline of physical activity, screen time and sleep duration, among which 42.80% and 28.77% met the guideline for one or two out of three behaviors, respectively. Only 6.76% of children and adolescents met the guideline of all three behaviors. Logistic regression analysis showed that the risk of overweight and obesity was negatively correlated with sleep duration ( OR=0.72, 95% CI=0.52−0.98). The risk of overweight and obesity was lower in patients with 2 criteria than in those with less sleep duration and less screen time ( OR=0.57, 95% CI=0.36−0.87).

          Conclusion Percentage of sufficient physical activity among children and adolescents in Beijing-Tianjin-Hebei region is low, and ensuring sufficient sleep duration is helpful for overweight and obesity prevention. The impact of sleep duration and screen time on overweight and obesity in children and adolescents should be considered in childhood obesity prevention and control.

          Abstract

          【摘要】 目的 了解京津冀地区儿童青少年体力活动、视屏和睡眠状况及其与超重肥胖的关系, 为京津冀地区儿童青少 年保持健康体型提供参考和借鉴。 方法 2019年11月借助全国学生体质健康调研工作, 参考儿童青少年体力活动指南 对京津冀地区4 262名中小学生进行体力活动、睡眠状况、视屏时间调査, 并采用Logistic回归分析其与超重肥胖之间存在 的关联。 结果 京津冀地区儿童青少年超重肥胖检出率为22.03%; 其中超重检出率12.01%, 肥胖检出率10.02%。男生 (26.09%)超重肥胖检出率髙于女生(17.88%), 差异有统计学意义(χ 2=41.77, P<0.01); 城市(24.09%)和汉族(22.74%)儿 童青少年超重肥胖检出率髙于乡村(21.05%)和少数民族(17.70%), 差异均有统计学意义(χ 2值分别为5.00, 7.63, P值均<0.05)。体力活动时间合格率为24.85%, 视屏时间合格率为38.69%, 睡眠时间合格率为57.09%。体力活动时间、视屏时 间、睡眠时间3项均不合格的比例为21.68%, 1项合格和2项合格分别占42.80%和28.77%, 3项均合格的仅占6.76%。Logistic 回归分析显示, 睡眠时间合格与超重肥胖发生的风险呈负相关( OR=0.72, 95% CI=0.52~0.98); 与睡眠时间和视屏时 间均未合格者相比, 2项合格与超重肥胖的发生风险呈负相关( OR=0.57, 95% CI=0.36~0.87)。 结论 京津冀地区儿童青 少年体力活动时间合格率较低, 保障睡眠时间将对超重肥胖的发生起到保护作用。应注重睡眠时间和视屏时间对儿童青 少年超重肥胖的影响, 并在以后的防控和干预中得以应用。
