          Abstract

          Objective To investigate the associations of moderate-to-vigorous intensity physical activity (MVPA) and screen time (ST) with emotional and behavioral problems in children and to provide evidence for related intervention measures.

          Methods In March 2017, a total of 4 922 children aged 6–12 years from 5 primary schools in Guangzhou were enrolled using stratified random cluster sampling method. Questionnaires were used to assess children’s socio-demographic information, MVPA, ST and emotional and behavioral problems. The associations of MVPA and ST with behavioral problems were explored by using generalized linear mixed models.

          Results Students with MVPA ≥60 min per day accounted for 37.5%, and with ST ≤2 h per day accounted for 87.7%. Children who were physically active showed lower scores for total difficulties, hyperactivity, and peer problems and higher score for prosocial than inactive peers ( t = 2.80, 2.47, 2.56, −1.97, all P<0.05). Also, children who spent less than 2 h ST per day reported lower scores for total difficulties, emotional symptoms, conduct problems, hyperactivity, and peer problems and higher score for prosocial compared to those with high ST ( t = 3.18, 3.35, 3.70, 3.80, −3.21, 4.97, all P<0.05). Children who met neither MVPA nor ST recommendations had significantly increased risks of total difficulties ( OR = 1.73, 95% CI = 1.12-2.68), conduct problems ( OR =1.45, 95% CI = 1.02-2.05), peer problems ( OR = 1.93, = 1.11-3.36), and prosocial ( OR = 1.55, 95% CI = 1.08-2.23) than those who met both.

          Conclusion MVPA and ST are independently related to children’s emotional and behavioral problems, and the risks of emotional and behavioral problems increased in children with insufficient MVPA and longer ST.

          Abstract

          【摘要】 目的 探讨中高等强度体力活动 (modemte-to-vigorous intensity physical activity, MVPA)、视屏时间 (screen time, ST) 和儿童情绪与行为问题的关联, 为筛查学龄儿童心理问题和制定相关干预措施提供参考。 方法 采用分层整群随机抽样, 于 2017 年 3 月在广州市 5 个区各抽取 1 所小学, 纳入 4 922 名 6~12 岁小学生。问卷收集学生的社会人口学信息、MVPA、ST 和情绪行为问题。采用广义线性混合回归模型分析 MVPA、ST 和情绪行为问题的关系。 结果 平均每天 MVPA ≥ 60 min 的学生占 37.5%, 平均每天 ST ≤2 h 的学生占 87.7%。与低水平 MVPA 组 (<60 min/d) 相比, 高水平 MVPA 组 (≥60 min/d) 学生在多动行为、同伴交往和困难总分较低, 亲社会行为得分较高 ( t 值分别为 2.80, 2.47, 2.56, −1.97, P 均<0.05)。与高水平ST组(>2 h/d)相比, 低水平ST组 (≤2 h/d) 儿童在情绪症状、品行问题、多动行为、同伴交往和困难总分各维度得分较低, 亲社会行为得分较高 ( t 值分别为 3.18, 3.35, 3.70, 3.80, −3.21, 4.97, P 值均<0.05)。低水平 MVPA 和高水平ST的联合暴露会增加儿童品行问题( OR =1.45, 95% CI = 1.02~2.05)、同伴交往( OR = 1.93, 95% CI = 1.11~3.36)、亲社会行为 ( OR = 1.55, 95% CI =1.08~2.23)和困难总分 ( OR = 1.73, 95% CI =1.12~2.68)发生风险。 结论 MVPA 和ST独立与儿童情绪和行为问题有关, 且 MVPA 不足和ST较长的联合暴露可以增加儿童情绪与行为问题的发生风险。
