          Abstract

          Objective To explore correlations between physical activity (PA), sedentary behavior (SB) and physical posture disorders in primary school students, and to provide reference for the prevention and correction of adverse body posture in this group.

          Methods From September to December 2020, 206 children from 4 primary schools in Chaoyang District of Beijing were selected by multistage stratified cluster random sampling method. Body posture and PA were assessed using a body posture tester and a triaxial accelerometer. Children’s Leisure Activity Questionnaire was used to investigate SB.

          Results The detection rate of abnormal body posture in primary school students was 76.70%. PA showed positive assocation with high and low shoulder, X/O leg, pelvis forward, spine curvature and comprehensive evaluation ( β = 0.17, 0.21, 0.19, 0.24, 0.19, P<0.05). SB had significant negative linear correlation with high and low shoulder, X/O leg, pelvis forward, spine curvature and comprehensive evaluation ( β = −0.24, −0.22, −0.36, −0.24, −0.27, P<0.05). In the combination analysis, children with high PA plus low SB ( OR = 2.12, 95% CI = 1.46-3.37, P<0.05) and children with low PA plus high SB had the highest and lowest advantages of qualified rate of body posture assessment, respectively. Compare with low SB and low PA ( OR = 1.71, 95% CI = 1.41-2.74, P<0.05), high PA and high SB ( OR = 1.85, 95% CI = 1.38-2.86, P<0.05) had higher qualified rate of body posture assessment.

          Conclusion Physical activity shows positive effects on physical posture while sedentary behavior shows negative effects on physical posture. The combination of PA and SB has a counteracting or synergistic interaction effect.

          Abstract

          【摘要】 目的 探究小学生身体活动(physical activity, PA)、久坐行为(sedentary behavior, SB)与身体姿态健康的关系, 为 该群体异常身体姿态预防、矫正提供参考。 方法 2020年9一12月, 采用多阶段分层整群随机抽样法, 抽取北京市朝阳区 4所学校206名小学生为研究对象, 采用Body-Style身体姿态测试仪、ActiGraph GT3X+三轴加速度计客观测量身体姿态、 PA, 采用儿童休闲活动调査问卷调査SB。 结果 小学生异常身体姿态检出率为76.70%;PA与髙低肩、X/O型腿、骨盆前 倾、脊柱侧弯、综合测评具有正向线性相关( β值分别为0.17, 0.21, 0.19, 0.24, 0.19, P值均<0.05);SB与髙低肩、X/O型腿、 骨盆前倾、脊柱侧弯、综合测评具有负向线性相关( β值分别为 −0.24, −0.22, −0.36, −0.24, −0.27, P值均<0.05)。对PA、SB 联合分析, 在髙PA、低SB( OR = 2.12, 95% CI = 1.46~3.37, P<0.05)和低PA、髙SB两个极端组合时, 身体姿态测评合格率获 得优势分别为最髙和最低;髙 PA、髙 SB ( OR = 1.85, 95% CI = 1.38~2.86)与低 SB、低 PA ( OR = 1.71, 95% CI = 1.41~2.74)比 较, 身体姿态测评合格率获得优势更髙。 结论 对于小学生身体姿态健康, PA是独立促进因素, SB是独立危险因素, 二者 联合具有抵消或协同的交互效应。
