目的：估计美国 5 个主要种族/族裔群体 4 岁儿童的肥胖患病率。设计：横断面二次数据分析。背景：2001 年出生的美国儿童的全国代表性样本。参与者：2005 年对参与早期儿童纵向研究出生队列的大约 8550 名儿童进行了身高和体重测量。主要暴露：种族/民族群体。结果测量：患病率 肥胖，定义为体重指数等于或高于特定性别疾病控制和预防中心生长图表中年龄的第 95 个百分位。结果：美国 4 岁儿童（平均年龄，52.3 个月）的肥胖患病率为 18.4%（95% 置信区间 [CI]，17.1%-19.8%）。肥胖患病率因种族/族裔群体而异 (P < .001)：美洲印第安人/阿拉斯加原住民，31.2%（95% CI，24.6%-37.8%）；西班牙裔，22.0%（95% CI，19.5%-24.5%）；非西班牙裔黑人，20.8%（95% CI，17.8%-23.7%）；非西班牙裔白人，15.9%（95% CI，14.3%-17.5%）；亚洲人为 12.8%（95% CI，10.0%-15.6%）。经过 Bonferroni 调整后，种族/族裔群体之间肥胖患病率的所有成对差异均具有统计学显着性（P
Objective: To estimate the prevalence of obesity in 5 major racial/ethnic groups in 4-year-old US children.Design: Cross-sectional secondary data analysis.Setting: Nationally representative sample of US children born in 2001.Participants: Height and weight were measured in 2005 in approximately 8550 children who participated in the Early Childhood Longitudinal Study, Birth Cohort.Main Exposure: Racial/ethnic group.Outcome Measure: Prevalence of obesity, defined as body mass index at or above the 95th percentile for age of the sex-specific Centers for Disease Control and Prevention growth charts.Results: Obesity prevalence among 4-year-old US children ( mean age, 52.3 months) was 18.4% (95% confidence interval [CI], 17.1%-19.8%). Obesity prevalence differed by racial/ethnic group (P < .001): American Indian/Native Alaskan, 31.2% ( 95% CI, 24.6%-37.8%); Hispanic, 22.0% ( 95% CI, 19.5%-24.5%); non-Hispanic black, 20.8% ( 95% CI, 17.8%-23.7%); non-Hispanic white, 15.9% ( 95% CI, 14.3%-17.5%); and Asian, 12.8% ( 95% CI, 10.0%-15.6%). All pairwise differences in obesity prevalence between racial/ethnic groups were statistically significant after a Bonferroni adjustment (P
