摘要： 目的了解学龄儿童日常身体活动现况,及其与家庭支持性因素的关系,为促进儿童身体活动提供参考依据。方法 2022年4—6月,选取杭州市某小学88名8~12岁学龄儿童为研究对象,平均年龄(10.72±0.96)岁,男童57人(64.8%),连续7天佩戴三轴加速度计采集睡眠、久坐行为、低强度身体活动(LPA)和中高强度身体活动(MVPA)指标,使用身体活动家庭支持性问卷(PAP-C)对儿童自我感知的家庭支持性因素(父母自主支持、父母参与度和父母身体活动结构)进行调查。多重线性回归方法分析身体活动与家庭支持性因素的关联。结果学龄儿童日均睡眠(9.28±0.71)h,久坐行为(10.12±1.19)h,LPA(2.99±0.86)h,MVPA(1.61±0.57)h。总体而言,家庭支持性因素与学龄儿童MVPA时间存在显著关联(P<0.05),与睡眠时间、久坐时间无显著关联(P>0.05)。性别比较显示,父母自主支持得分与男童MVPA时间呈正相关(β=0.281,P<0.05);父母身体活动结构得分与女童LPA时间呈负相关(β=-0.760,P<0.05)。结论学龄儿童整体呈现久坐时间较长、身体活动水平较高特征。家庭支持性因素与学龄儿童MVPA关系密切,未来需要重视家庭支持性环境对学龄儿童身体活动的影响。

Abstract: Objective To assess the level of daily physical activity, and associations between daily physical activity and family supportive factors for school-aged children, in order to provide a reference for promoting children's physical activity. Methods From April to June 2024, a total of 88 school-aged children aged 8 - 12 years were recruited from an elementary school in Hangzhou, with the average age of (10.72±0.96) years old. Among them, 57(64.8%) were boys. All the participants wore triaxial accelerometers for 7 consecutive days to collect data on sleep, sedentary behavior , low-intensity physical activity (LPA), and moderate-to-vigorous physical activity (MVPA). The Physical Activity Parenting Questionnaire for Children (PAP-C) was used to assess children's self-perceived family supportive factors, including parental autonomy support, parental involvement, and parental physical activity structure. Multiple linear regression analysis was conducted to examine the associations between physical activity and family supportive factors. Results The average daily sleep duration of school-aged children was (9.28±0.71) hours, sedentary time was (10.12±1.19) hours, LPA was (2.99±0.86) hours, and MVPA was (1.61±0.57) hours. Overall, family supportive factors were significantly associated with MVPA time in school-aged children (P<0.05), but not with sleep duration or SB time (P>0.05). Gender-specific analysis revealed that parental autonomy support scores were positively correlated with MVPA time in boys (β＝0.281, P<0.05), while parental physical activity structure scores were negatively correlated with LPA time in girls (β＝-0.760, P<0.05). Conclusions School-aged children generally exhibit prolonged sedentary time and relatively high levels of physical activity. Family supportive factors are closely related to MVPA in school-aged children. Future efforts should emphasize the influence of family supportive environments on the physical activity of school-aged children.
