目的：BMI（千克/平方米）在一生中的变化模式存在种族差异的可能性尚未得到研究。例如，黑人妇女肥胖率高可能是由于黑人女孩肥胖率较高，或者是因为体重正常的黑人女孩在青春期或成年期的BMI增加幅度大于白色女孩。因此，我们研究了跟踪儿童体重指数到成年期的birabenth（36%的黑人）sample.Research方法和程序：5至14岁的儿童（2392）进行了跟踪（平均）17年。儿童期超重定义为BMI ≥ 95百分位数，成人期肥胖定义为BMI ≥ 30 kg/m2。在超重儿童中，65%的白色女孩和84%的黑人女孩成为肥胖成年人，男孩的预测值分别为71%（白人）和82%（黑人）。这些种族差异反映了BMI变化率的对比模式。尽管黑人儿童的初始BMI并不高于白色儿童，但黑人女孩和超重黑人男孩的BMI随年龄增长的幅度大于白色儿童。相比之下，相对较瘦（BMI <50百分位）的白色男孩更容易成为超重的成年人比他们的黑人countermeasurement.Discussion：这些研究结果强调了黑人/白色的差异，随着年龄的增长，BMI的变化。由于儿童期发病的肥胖对成人健康的影响，早期预防应给予额外的重视。
Objective: The possibility that there are racial differences in the patterns of BMI (kilograms per meter squared) change throughout life has not been examined. For example, the high prevalence of obesity among black women could result from a higher prevalence of obesity among black girls or because normal-weight black girls experience larger BMI increases in adolescence or adulthood than do their white counterparts. Therefore, we examined the tracking of childhood BMI into adulthood in a biracial (36% black) sample.Research Methods and Procedures: Five- to 14-year-old children (2392) were followed for (mean) 17 years. Childhood overweight was defined as BMI >= 95th percentile, and adult obesity was defined as BMI >= 30 kg/m(2).Results: The tracking of childhood BMI differed between whites and blacks. Among overweight children, 65% of white girls vs. 84% of black girls became obese adults, and predictive values among boys were 71% (whites) vs. 82% (blacks). These racial differences reflected contrasting patterns in the rate of BMI change. although the initial BMI of black children was not higher than that of white children, BMI increases with age were larger among black girls and overweight black boys than among their white counterparts. In contrast, relatively thin (BMI < 50th percentile) white boys were more likely to become overweight adults than were their black counterparts.Discussion: These findings emphasize the black/white differences in BMI changes with age. Because of the adult health consequences of childhood- onset obesity, early prevention should be given additional emphasis.
