To determine the association between the prevalence of obesity in preschool-aged children and exposure to 3 household routines: regularly eating the evening meal as a family, obtaining adequate sleep, and limiting screen-viewing time.
We conducted a cross-sectional analysis of a nationally representative sample of approximately 8550 four-year-old US children who were assessed in 2005 in the Early Childhood Longitudinal Study, Birth Cohort. Height and weight were measured. We assessed the association of childhood obesity (BMI > or = 95th percentile) with 3 household routines: regularly eating the evening meal as a family (>5 nights per week); obtaining adequate nighttime sleep on weekdays (> or =10.5 hours per night); and having limited screen-viewing (television, video, digital video disk) time on weekdays (< or =2 hours/day). Analyses were adjusted for the child's race/ethnicity, maternal obesity, maternal education, household income, and living in a single-parent household.
Eighteen percent of children were obese, 14.5% were exposed to all 3 routines, and 12.4% were exposed to none of the routines. The prevalence of obesity was 14.3% (95% confidence interval [CI]: 11.3%-17.2%) among children exposed to all 3 routines and 24.5% (95% CI: 20.1%-28.9%) among those exposed to none of the routines. After adjusting for covariates, the odds of obesity associated with exposure to all 3, any 2, or only 1 routine (compared with none) were 0.63 (95% CI: 0.46-0.87), 0.64 (95% CI: 0.47-0.85), and 0.84 (95% CI: 0.63-1.12), respectively.
US preschool-aged children exposed to the 3 household routines of regularly eating the evening meal as a family, obtaining adequate nighttime sleep, and having limited screen-viewing time had an approximately 40% lower prevalence of obesity than those exposed to none of these routines. These household routines may be promising targets for obesity-prevention efforts in early childhood.
确定学龄前儿童肥胖患病率与 3 种家庭常规之间的关系：经常全家一起吃晚餐、获得充足的睡眠以及限制屏幕观看时间。
我们对大约 8550 名四岁的美国儿童进行了一项基于全国代表性样本的横断面分析，这些儿童于 2005 年参加了幼儿纵向研究-出生队列。测量了身高和体重。我们评估了儿童肥胖症（BMI＞等于第 95 百分位数）与 3 种家庭常规之间的关系：经常全家一起吃晚餐（每周＞等于 5 天）；工作日获得足够的夜间睡眠（每晚＞等于 10.5 小时）；工作日限制屏幕观看时间（电视、视频、数字视频光盘）（＜等于 2 小时/天）。分析调整了儿童的种族/民族、母亲肥胖、母亲教育、家庭收入和单亲家庭状况。
18%的儿童肥胖，14.5%接触到 3 种常规中的所有 3 种，12.4%接触到 3 种常规中的任何 1 种。接触到 3 种常规的儿童肥胖患病率为 14.3%（95%置信区间：11.3%-17.2%），而接触到 3 种常规中任何 1 种的儿童肥胖患病率为 24.5%（95%置信区间：20.1%-28.9%）。调整协变量后，与未接触到任何常规相比，接触到所有 3 种、任何 2 种或仅 1 种常规（比较）的肥胖症患病几率分别为 0.63（95%置信区间：0.46-0.87）、0.64（95%置信区间：0.47-0.85）和 0.84（95%置信区间：0.63-1.12）。
接触经常全家一起吃晚餐、获得充足夜间睡眠和限制屏幕观看时间这 3 种家庭常规的美国学龄前儿童肥胖患病率比未接触这些常规的儿童低约 40%。这些家庭常规可能是幼儿期肥胖预防工作的有希望的目标。
