目的 了解山西省初中生身体活动现状及其影响因素,为促进开展身体活动提供参考。 方法 2024年2—7月,采用分层随机抽样的方法从山西省太原市、吕梁市、运城市、晋城市和大同市共8所中学抽取532名初中生参与测试。身体活动采用ActiGraph wGT3X-BT加速度计进行测量,测试结束后使用 ActiLife version 6.13.6 软件对加速度计数据进行筛选与分析。采用χ2检验比较不同特征初中生身体活动达标情况,采用二元logistic回归模型分析初中生身体活动达标情况相关影响因素。 结果 山西省初中生身体活动达标率为17.1%。二元logistic回归分析显示,男生(OR=8.58,95%CI:4.73~15.57,P＜0.05)、非寄宿于学校(OR=1.95,95%CI:1.11~3.43,P＜0.05)是身体活动达标的促进因素。 结论 山西省初中生身体活动达标率较低,性别和寄宿于学校是影响山西省初中生身体活动达标情况的重要因素。需要对女生和寄宿于学校学生开展针对性干预措施,提高学生的身体活动参与程度。
Abstract
Objective To investigate the current status of physical activity (PA) and its influencing factors among junior high school students in Shanxi Province, China, in order to provide evidence for promoting PA participation. Methods From February to July 2024, a stratified random sampling method was used to recruit 532 junior high school students from 8 secondary schools in Taiyuan, Lyuliang, Yuncheng, Jincheng, and Datong cities of Shanxi Province.PA levels were objectively measured using ActiGraph wGT3X-BT accelerometers, and data were processed using ActiLife software (version 6.13.6).Chi-square tests were used to compare PA compliance rates across different demographic groups, and binary logistic regression was employed to identify factors associated with meeting PA recommendations. Results The compliance rate with PA recommendations among junior high school students in Shanxi Province was 17.1%.Binary logistic regression analysis revealed that male gender (OR=8.58, 95%CI: 4.73 - 15.57, P<0.05) and non-boarding school status (OR=1.95, 95%CI: 1.11 - 3.43, P<0.05) were significant positive predictors of meeting PA recommendations. Conclusions The compliance rate with PA recommendations among junior high school students in Shanxi Province remains suboptimal.Gender and boarding school status are identified as key determinants of PA participation.Targeted interventions should be implemented to enhance overall PA engagement, particularly for female students and boarding school students.
