Children from families speaking a non-official language at home may be particularly at risk for low physical activity (PA), underscoring a need to investigate correlates of PA in this subpopulation.
We recruited 478 children in 37 schools stratified by area-level socioeconomic status (SES) and type of urbanization within three regions of Canada. Steps/day were measured using SC-StepRx pedometers. We assessed potential social-ecological correlates with child and parent surveys. We used gender-stratified linear mixed models to examine the correlates of steps/day.
Outdoor time was the strongest correlate of boys' and girls' PA. Lower area-level SES was associated with less PA among boys, but outdoor time attenuated this difference. The strength of association between outdoor time and PA decreased with age in boys and increased with age in girls.
Outdoor time was the most consistent correlate of PA. Future interventions should promote outdoor time and address socioeconomic disparities.
在家中使用非官方语言的家庭的儿童可能特别容易出现低身体活动（PA）的情况，这突显了需要调查这一亚人群的 PA 相关因素。
我们在加拿大三个地区的 37 所学校中，按地区社会经济地位（SES）和城市化类型对 478 名儿童进行了分层招募。使用 SC-StepRx 计步器测量每天的步数。我们使用儿童和家长调查评估了潜在的社会生态相关因素。我们使用性别分层线性混合模型来检验与每日步数相关的因素。
户外活动时间是男孩和女孩 PA 的最强相关因素。较低的地区社会经济地位与男孩的 PA 较少有关，但户外活动时间减轻了这种差异。户外活动时间与 PA 之间的关联强度在男孩中随年龄的增长而降低，在女孩中随年龄的增长而增加。
户外活动时间是 PA 最一致的相关因素。未来的干预措施应促进户外活动时间，并解决社会经济差距问题。
