Background: The main aim of this study was to quantify the associations between parents’ and children’s physical activity by age, gender, and the day of the week on the basis of a pedometer-measured step count (SC). Methods: The sample comprised data from 4-to 16-year-old children and their parents from the Czech Republic (1102 mother-child dyads and 693 father-child dyads). The parents and their children wore the Yamax SW200 pedometer during seven days of monitoring. Results: The strongest SC association was found between mothers and daughters aged 4–7.9 years on weekdays (r_p = 0.402; p < 0.01) and at weekends (r_p = 0.577; p < 0.01). In children aged 8–16, the parent-child association is gender-specific, with the father-son relationship being dominant, especially at weekends (weekend SC: fathers-sons_{8–11.9 y} r_p = 0.416, p < 0.01; fathers-sons_{12–16 y} r_p = 0.443, p < 0.01). An increase of 1000 steps in the fathers (mothers) is associated with an increase of more than 400 (200) steps in their sons (daughters). Conclusions: This study confirms a strong parent-child SC relationship in children younger than eight years of age. In older children, the parent-child SC association is gender-specific and dominated by the father-son relationship, particularly on weekends. The SC associations that are revealed can be used for the development of physical activity programs for adolescents.

4至16岁儿童家庭中的亲子体育活动协会。

背景：本研究的主要目的是基于计步器测量的步数（SC），通过年龄，性别和星期几来量化父母和孩子的体育活动之间的关联。方法：该样本包括来自捷克共和国的4至16岁儿童及其父母的数据（1102个母子双子和693个父子双子）。父母和他们的孩子在监视的七天内佩戴了Yamax SW200计步器。结果：在工作日（r _p = 0.402；p < 0.01）和周末（r _p = 0.577；p < 0.01）。在8-16岁的儿童，父-子关联是性别特异性的，与所述父子关系（占主导地位，特别是在周末周末SC：父亲-儿子_8-11.9Ŷ - [R _p = 0.416，p < 0.01;父亲子_{12–16 y} r _p = 0.443，p < 0.01）。父亲（母亲）增加1000步，其儿子（女儿）增加400（200）步。结论：这项研究证实了八岁以下儿童的亲子SC关系牢固。在较大的孩子中，亲子SC协会是特定于性别的，并且由父子关系主导，尤其是在周末。揭示的SC关联可用于开发青少年的体育锻炼计划。
