目的：在过去的30年里，美国儿童超重的患病率显著增加。我们研究了白色、黑人和墨西哥裔美国儿童的BMI、体重和身高的长期趋势差异。研究方法和程序：分析基于在4次检查中收集的2至17岁儿童的全国代表性数据结果：总体而言，黑人儿童在BMI、体重和身高方面的长期增长要比白色儿童大得多。例如，在30年的时间里，6至11岁的白色儿童的超重患病率增加了3倍（4%至13%），而黑人儿童增加了5倍（4%至20%）。在大多数性别年龄组中，墨西哥裔美国儿童的BMI增加和超重介于黑人和白人之间。在2至5奥尔兹中，种族/民族差异不太明显，在这个年龄组中，白色儿童的超重增加幅度最大（从4%增加到9%）。在1999-2002年，极端BMI水平（>= 99 th百分位数）的患病率达到6%至7%的黑人女孩和墨西哥裔美国男孩。讨论：由于儿童期BMI水平到成年期的强烈跟踪，很可能儿童期超重的长期增加将大大增加成人疾病的负担。应强调在不同种族/族裔群体中进一步发展肥胖干预措施。
Objectives: The prevalence of childhood overweight in the United States has markedly increased over the last 30 years. We examined differences in the secular trends for BMI, weight, and height among white, black, and Mexican-American children.Research Methods and Procedures: Analyses were based on nationally representative data collected from 2 to 17 year olds in four examinations (1971-1974 through 1999-2002).Results: Overall, black children experienced much larger secular increases in BMI, weight, and height than did white children. For example, over the 30-year period, the prevalence of overweight increased similar to 3-fold (4% to 13%) among 6- to 11-year-old white children but 5-fold (4% to 20%) among black children. In most sex-age groups, Mexican-American children experienced increases in BMI and overweight that were between those experienced by blacks and whites. Race/ethnicity differences were less marked among 2 to 5 year olds, and in this age group, white children experienced the largest increase in overweight (from 4% to 9%). In 1999-2002, the prevalence of extreme BMI levels (>= 99th percentile) reached 6% to 7% among black girls and Mexican-American boys.Discussion: Because of the strong tracking of childhood BMI levels into adulthood, it is likely that the secular increases in childhood overweight will greatly increase the burden of adult disease. The further development of obesity interventions in different racial/ethnic groups should be emphasized.
