目的比较不同种族背景幼儿超重的发生率，描述儿童早期超重的年龄模式。方法对1997-1998年间参加夏威夷妇女、婴儿和儿童特别补充营养计划的21,911名12~59个月的儿童进行横断面研究。他们被分成八个种族类别。对于1岁的儿童，我们将超重定义为第95个百分位数或更大的年龄体重，将体重不足定义为低于第10个百分位数的年龄体重。对于2至4岁的儿童，超重定义为身体质量指数(BMI)在第95个百分位数或更高，体重不足定义为BMI小于10个百分位数，身高定义为按年龄计算的身高在第95个百分位数或更高，矮个子定义为身材矮小(低于10个百分位数)。国家卫生统计中心2000年的增长图表是参考值。结果不同民族间存在较大差异。在1岁儿童中，萨摩亚人最重(17.5%超重)，菲律宾人最轻(30.2%体重不足)。在2到4岁的儿童中，萨摩亚人最重(超重27.0%)，身高最高(16.9%)，而亚洲人最轻(体重不足12.2%)，菲律宾人最矮(19.0%)。夏威夷人和亚洲人的矮子比例也很高(分别为13.6%和12.2%)。所有2-4岁儿童的超重患病率都超过了预期的5%，特别是萨摩亚人、菲律宾人、夏威夷人和亚洲人。在2~4岁年龄段，超重的发生率几乎是1岁时的两倍。多因素分析显示，在两个年龄组中，种族(萨摩亚人)与年龄体重百分位数、BMI和超重的独立关联性最强，其次是出生体重。结论这是夏威夷首次对具有亚洲和太平洋岛屿背景的儿童进行超重研究。它确定了生长的重要特征，并将有助于设计适当的活动以防止超重。
Objectives To compare the prevalence of overweight among young children of different ethnic backgrounds and describe the age pattern of overweight in early childhood.Methods Cross-sectional study of 21,911 children, 12 to 59 months old, participating in the Hawaii Special Supplemental Nutrition Program for Women, Infants, and Children in 1997-1998. They were grouped in eight ethnic categories. For 1-year-olds we defined overweight as weight-for-age at the 95th percentile or more and underweight as weight-for-age at less than the 10th percentile. For 2- to 4-year-olds overweight was defined as body mass index (BMI) at the 95th percentile or more, underweight as BMI less than 10th percentile, tall stature as height-for-age at the 95th percentile or more, and short stature as height-for-age at less than the 10th percentile. The National Center for Health Statistics 2000 growth charts were the reference values. The analysis included bivariate and multivariate methods.Results Large differences were found among ethnic groups. Among 1-year-olds, Samoans were the heaviest (17.5% overweight) and Filipinos the lightest (30.2% underweight). Among 2- to 4-year-olds, Samoans were the heaviest (27.0% overweight) and the tallest (16.9% tall), whereas Asians were the lightest (12.2% underweight), and Filipinos the shortest (19.0% short). Hawaiians and Asians also had a high percentage of short children (13.6% and 12.2%, respectively). Prevalence of overweight in all 2- to 4-year-olds was more than the expected 5%, especially for Samoans, Filipinos, Hawaiians, and Asians. At age 2 to 4 years, overweight was almost twice as prevalent as at age 1. Multivariate analysis showed that ethnicity (Samoan) had the strongest independent association with weight-for-age percentile, BMI, and overweight in the two age groups, followed by birth weight.Conclusions This is the first study of overweight among children of Asian and Pacific Island backgrounds in Hawaii. It identified important characteristics of growth and will be helpful in the design of appropriate activities to prevent overweight.
