To examine associations between social vulnerabilities and meeting physical activity (PA) and screen time (ST) recommendations during a 2-year follow-up.
13,891 children aged 2.0 to < 9.9 from eight European countries were assessed at baseline and 8482 children at follow-up. Children's sports club membership, PA and ST were collected via parental questionnaires. Moderate-to-vigorous physical activity (MVPA) was objectively assessed with accelerometers. Performing at least 1 h of MVPA daily and spending less than 2 h of ST defined physically active and non-sedentary children, respectively. Vulnerable groups were defined at baseline as children whose parents had minimal social networks, from non-traditional families, with migrant origin or with unemployed parents. Logistic mixed-effects analyses were performed adjusting for classical socioeconomic indicators.
Children whose parents had minimal social networks had a higher risk of non-compliance with PA recommendations (subjectively assessed) at baseline. Migrants and children with unemployed parents had longer ST. All vulnerable groups were less likely to be sports club members.
Migrants and children with unemployed parents are at risk for excessive ST and all vulnerable groups have lower odds of being sports club members.
在为期两年的随访中，研究社会脆弱性与达到身体活动（PA）和屏幕时间（ST）建议之间的关联。
在基线评估时，来自八个欧洲国家的 13891 名年龄为 2.0 至<9.9 岁的儿童和在随访时的 8482 名儿童参与了研究。通过家长问卷收集儿童参加运动俱乐部、PA 和 ST 的情况。使用加速度计客观评估中等到剧烈的身体活动（MVPA）。每天至少进行 1 小时的 MVPA 运动且每天 ST 不超过 2 小时分别定义为身体活跃和非久坐的儿童。脆弱群体在基线时定义为父母社交网络很少、来自非传统家庭、有移民背景或父母失业的儿童。使用逻辑混合效应分析，在调整经典社会经济指标后进行分析。
父母社交网络很少的儿童在基线时不符合 PA 建议（主观评估）的风险更高。移民和失业父母的儿童 ST 时间更长。所有脆弱群体成为运动俱乐部成员的可能性较小。
移民和失业父母的儿童面临 ST 过长的风险，所有脆弱群体成为运动俱乐部成员的可能性较小。
