对365名3-5岁的低收入非裔美国学龄前儿童的代表性样本进行了研究，以确定含糖饮料消费（苏打水，水果饮料以及两者结合）与超重和肥胖之间的关系。2002-2003年，儿童在牙科诊所接受了检查，两年后再次接受检查。饮食信息收集使用街区儿童食物频率问卷。根据记录的身高和体重计算BMI评分。超重和肥胖由国家参考年龄-性别特异性BMI定义：年龄-性别特异性BMI >= 85 th，但年龄-性别特异性BMI = 95 th的人为肥胖。基线时超重的患病率为12.9%，2年后增加到18.7%。在同一时期，肥胖的流行率从10.3%上升到20.4%。苏打水和所有含糖饮料的基线摄入量与基线BMI z评分呈正相关。在调整协变量后，基线时额外摄入水果饮料和所有含糖饮料显示2年内超重发生率显著较高。在一组非裔美国学龄前儿童的纵向队列中，大量饮用含糖饮料与肥胖风险增加显著相关。
A representative sample of 365 low-income African-American preschool children aged 3-5 years was studied to determine the association between sugar-sweetened beverage consumption (soda, fruit drinks, and both combined) and overweight and obesity. Children were examined at a dental clinic in 2002-2003 and again after 2 years. Dietary information was collected using the Block Kids Food Frequency Questionnaire. A BMI score was computed from recorded height and weight. Overweight and obesity were defined by national reference age-sex specific BMI: those with an age-sex specific BMI >= 85th, but = 95th age-sex specific percentile as obese. The prevalence of overweight was 12.9% in baseline, and increased to 18.7% after 2 years. The prevalence of obesity increased from 10.3 to 20.4% during the same period. Baseline intake of soda and all sugar-sweetened beverages were positively associated with baseline BMI z-scores. After adjusting for covariates, additional intake of fruit drinks and all sugar-sweetened beverages at baseline showed significantly higher odds of incidence of overweight over 2 years. Among a longitudinal cohort of African-American preschool children, high consumption of sugar-sweetened beverages was significantly associated with an increased risk for obesity.
