The study reveals the relationships between daily physical activity (PA) and the prevalence of obesity in family members separated according to the participation of their offspring in organized leisure-time physical activity (OLTPA), and answers the question of whether the participation of children in OLTPA is associated with a lower prevalence of obesity in offspring with respect to parental PA and body weight level.
The cross-sectional study included 1493 parent-child dyads (915/578 mother/father-child aged 4-16 years) from Czechia selected by two-stage stratified random sampling with complete data on body weight status and weekly PA gathered over a regular school week between 2013 and 2019.
The children who participated in OLTPA ≥ three times a week had a significantly lower ( < 0.005) prevalence of obesity than the children without participation in OLTPA (5.0% vs. 11.1%). Even in the case of overweight/obese mothers/fathers, the children with OLTPA ≥ three times a week had a significantly lower ( < 0.002) prevalence of obesity than the children without OLTPA (6.7%/4.2% vs. 14.9%/10.7%).
The cumulative effect of regular participation in OLTPA and a child's own PA is a stronger alleviator of children's obesity than their parents' risk of overweight/obesity.
本研究揭示了日常身体活动（PA）与根据子女参与有组织的闲暇时间体力活动（OLTPA）的情况而分开的家庭成员肥胖患病率之间的关系，并回答了以下问题：儿童参与 OLTPA 是否与父母 PA 和体重水平方面子女肥胖患病率较低有关。
本横断面研究包括来自捷克的 1493 对亲子对（915/578 名母亲/父亲-4-16 岁子女），采用两阶段分层随机抽样选择，在 2013 年至 2019 年期间，在常规学校周内收集了有关体重状况和每周 PA 的完整数据。
每周至少参加三次 OLTPA 的儿童肥胖患病率显著低于（<0.005）不参加 OLTPA 的儿童（5.0%比 11.1%）。即使对于超重/肥胖的母亲/父亲，每周至少参加三次 OLTPA 的儿童肥胖患病率也显著低于（<0.002）不参加 OLTPA 的儿童（6.7%/4.2%比 14.9%/10.7%）。
定期参与 OLTPA 和儿童自身 PA 的累积效应，比父母超重/肥胖的风险更能减轻儿童肥胖。
