We estimated overweight and obesity in New York City elementary school children.
A multistage cluster sample of New York City public elementary school children was selected. Nurses measured children's height and weight and used a standard protocol to determine body mass index (BMI). Demographic information was obtained from official school rosters. Overweight and obese were defined as BMI-for-age at or above the 85th and 95th percentiles, respectively.
Of 3069 sampled students, 2681 (87%) were measured. The prevalence of overweight was 43% (95% confidence interval [CI] = 39%, 47%), more than half of whom were obese. Overall prevalence of obesity was 24% (95% CI = 21%, 27%), with at least 20% obesity in each grade, including kindergarten. Hispanic children had significantly higher levels (31%; 95% CI = 29%, 34%) than Black (23%; 95% CI = 18%, 28%) or White children (16%; 95% CI = 12%, 20%). Asian children had the lowest level of obesity among all racial/ethnic groups (14.4%, 95% CI = 10.9, 18.7).
Obesity among public elementary school children in New York City is an important public health issue. Particularly high levels among Hispanic and Black children mirror national trends and are insufficiently understood.
我们对纽约市小学儿童的超重和肥胖情况进行了评估。
选取了纽约市公立小学儿童的多阶段整群样本。护士测量了儿童的身高和体重，并使用标准方案确定体重指数（BMI）。人口统计学信息从官方学校名册中获取。超重和肥胖分别定义为年龄别BMI处于或高于第85和第95百分位数。
在3069名抽样学生中，2681名（87%）接受了测量。超重患病率为43%（95%置信区间[CI]=39%，47%），其中一半以上为肥胖。肥胖总体患病率为24%（95%CI=21%，27%），每个年级（包括幼儿园）的肥胖率至少为20%。西班牙裔儿童的肥胖水平（31%；95%CI=29%，34%）显著高于黑人（23%；95%CI=18%，28%）或白人儿童（16%；95%CI=12%，20%）。亚洲儿童在所有种族/族裔群体中的肥胖水平最低（14.4%，95%CI=10.9，18.7）。
纽约市公立小学儿童肥胖是一个重要的公共卫生问题。西班牙裔和黑人儿童中尤其高的肥胖水平反映了全国趋势，且尚未得到充分了解。
