上海市2000—2010年学生体质健康状况变化趋势分析

目的了解父母因素对初中生校外闲暇时间体力活动的影响，为促进儿童青少年体力活动提供依据。方法用多层整群随机抽样的方法抽取6所中学的622名学生参与研究。问卷调查学生运动及父母影响因素，采用logistic回归分析影响因素。结果58.7%的家长会给子女购买运动装备，57.6%的家长在子女运动期间陪伴孩子一起运动。父母直观行为表率报告率为22.8%。获得父母后勤支持及父母直观行为表率的学生在双休日进行中、高强度身体活动(MVPA)情况较好，差异有统计学意义。logistic回归分析显示，有父母后勤支持的学生双休日出现MVPA达标是无父母后勤支持学生的1.51倍(95%CI：1.01~ 2.27)。结论父母后勤支持及直观行为表率能促进初中生进行MVPA，立足家庭干预可以提升子女校外体力活动水平。

Physical activity of Canadian children and youth, 2007 to 2015

ObjectiveTo investigate the effects of parental support for the moderate-to-vigorous physical activity (MVPA) of their children and to promote physical activity for children and adolescents.MethodsA total of 622 students were selected by stratified clustering sampling methods.Physical activity and parental support factors were assessed by self-report questionnaire survey.Logistic regression was used to analyze determinants of physical inactivity.ResultsNearly 58.7% of the parents purchased sports equipment for their children and 57.6% of the parents accompanied their children to do exercise.The rate of parental explicit modeling was 22.8%.The students who received parental logistic support and explicit modeling did longer MVPA on weekends.The students with parental logistic support were prone to be in activity (OR=1.51, 95%CI:1.01-2.27).ConclusionFamily-based interventions from parental logistic support and explicit modeling could promote middle-to-high-intensity activities for junior high school students.
