We examined associations between youth and caregiver moderate/ vigorous physical activity (MVPA) and sedentary (SED) time, using accelerometery, in the Hispanic Community Health Study/Study of Latino Youth (HCHS/ SOL) Youth.
Participants were 623 caregivers and 877 youth 8-16 years old, enrolled in 2012-2014. Associations of youth and caregiver MVPA time, SED time, and meeting MVPA recommendations ( 150 min/week, adults; 420 min/week, youth) were examined in regression models that controlled for sample weights, design effects, and demographic and health covariates.
Youth whose caregivers met MVPA recommendations were nearly twice as likely to meet these recommendations themselves when compared to youth whose caregivers did not meet MVPA recommendations (OR = 1.9, 95 CI 1.1, 3.3). Youth and caregiver SED time also were significantly related (p .05). A similar pattern of findings was observed in analyses limited to relationships in which the caregiver was a biological parent of the youth (N = 485 caregivers; N = 795 youth).
MVPA and SED are correlated within Latino families as observed by statistically significant relationships of youth and caregiver activity. Additional research is needed to understand underlying genetic and environmental factors that explain these findings.
在西班牙裔社区健康研究/拉丁裔青少年研究（HCHS/SOL）中，我们使用加速度计研究了青少年及其照顾者的中度/剧烈身体活动（MVPA）与久坐时间（SED）之间的关联。
参与者为2012年至2014年招募的623名照顾者和877名8至16岁的青少年。在控制了样本权重、设计效应以及人口统计学和健康协变量的回归模型中，研究了青少年及其照顾者的MVPA时间、SED时间以及是否达到MVPA建议（成年人每周150分钟；青少年每周420分钟）之间的关联。
与照顾者未达到MVPA建议的青少年相比，照顾者达到MVPA建议的青少年自己达到这些建议的可能性几乎是前者的两倍（OR = 1.9，95%置信区间1.1，3.3）。青少年及其照顾者的SED时间也显著相关（p <.05）。在仅限于照顾者为青少年亲生父母的关系分析中（485名照顾者；795名青少年），观察到了类似的结果模式。
正如青少年与照顾者活动之间具有统计学显著关系所观察到的那样，拉丁裔家庭中的MVPA和SED是相关的。需要进一步研究以了解解释这些发现的潜在遗传和环境因素。
