To describe time spent in sedentary and moderate-to-vigorous physical activity (MVPA) by children in Latino farmworker families and delineate sources of variation in sedentary and MVPA.
Data were from mother-child dyads (N = 248) in Latino farmworker households in North Carolina. Physical activity was assessed using accelerometers; mothers described their children's characteristics and their physical and social environments.
Children spent 6.2 hours/day sedentary (Median=369 minutes), and 6.0 minutes/day in MVPA. Children in Head Start spent more time sedentary, whereas children living where dogs roam freely were less sedentary. Children whose mothers limited screen time spent 2 more minutes in MVPA.
Preschool-aged Latino children in farmworker families are sedentary, engaging in little MVPA.
描述拉丁裔农场工人家庭儿童久坐和中度至剧烈身体活动(MVPA)的时间,并确定久坐和MVPA的变化来源。
数据来自北卡罗来纳州拉丁裔农场工人家庭的母婴二元组(N = 248)。使用加速度计评估身体活动;母亲们描述了孩子的特征以及他们的身体和社会环境。
儿童每天久坐6.2小时(中位数 = 369分钟),每天进行MVPA的时间为6.0分钟。参加Head Start项目的儿童久坐时间更长,而生活在有狗自由活动区域的儿童久坐时间较少。母亲限制孩子屏幕时间的儿童进行MVPA的时间多2分钟。
农场工人家庭中的学龄前拉丁裔儿童久坐不动,很少进行MVPA。
