目的：近几十年来，含糖饮料消费量的增加可能是美国青少年肥胖流行的部分原因。我们的目的是评估BMI变化与摄入加糖饮料、牛奶、果汁和无糖汽水之间的关系。研究方法和程序：我们的前瞻性队列研究包括参与美国今日成长研究的100万名男孩和女孩。参与者于1996年9至14岁，分别于1996年、1997年和1998年完成问卷调查。我们分析了在两个1年的时间里，完成了评估过去一年典型摄入量的年度食物频率问卷的儿童的BMI（每平方米公斤数）的变化。我们研究了与每次BMI变化相对应的一年内的饮料摄入量，在单独的模型中，我们研究了饮料摄入量的1年变化，并对前一年的摄入量进行了调整。模型同时包括所有饮料；进一步的模型调整总能量摄入。结果：在相应年份，饮用含糖饮料与BMI小幅增加相关(男孩：每天饮用+0.03 kg/m(2), p = 0.04；女生：+0.02 kg/m(2), P = 0.096)。在不假设线性剂量反应趋势的模型中，每天饮用1份含糖饮料的女孩比不饮用的女孩体重增加更多（+0.068,p = 0.02），每天饮用2份含糖饮料的女孩（+0.09,p = 0.06）或每天饮用3份含糖饮料的女孩（+0.08,p = 0.06）体重增加更多（+0.068,p = 0.02）。对饮料摄入量逐年变化的分析得出了大致相似的结果；从前一年开始增加含糖饮料消费量的男孩体重增加（每增加每日摄入量+0.04 kg/m(2), p = 0.01）。与前一年相比，每天增加2份或更多食物的儿童体重增加（男孩：+0.14,p = 0.01；女孩：+0.10,p = 0.046）。进一步调整我们的总能量摄入模型大大降低了估计的影响，不再显著。讨论：饮用含糖饮料可能会导致青少年体重增加，这可能是由于它们对总能量摄入的贡献，因为对卡路里的调整大大削弱了估计的关联。
Objective: The increase in consumption of sugar-added beverages over recent decades may be partly responsible for the obesity epidemic among U.S. adolescents. Our aim was to evaluate the relationship between BMI changes and intakes of sugar-added beverages, milk, fruit juices, and diet soda.Research Methods and Procedures: Our prospective cohort study included >10,000 boys and girls participating in the U.S. Growing Up Today Study. The participants were 9 to 14 years old in 1996 and completed questionnaires in 1996, 1997, and 1998. We analyzed change in BMI (kilograms per meter squared) over two 1-year periods among children who completed annual food frequency questionnaires assessing typical past year intakes. We studied beverage intakes during the year corresponding to each BMI change, and in separate models, we studied 1-year changes in beverage intakes, adjusting for prior year intakes. Models included all beverages simultaneously; further models adjusted for total energy intake.Results: Consumption of sugar-added beverages was associated with small BMI gains during the corresponding year (boys: +0.03 kg/m(2) per daily serving, p = 0.04; girls: +0.02 kg/m(2), P = 0.096). In models not assuming a linear dose-response trend, girls who drank 1 serving/d of sugar-added beverages gained more weight (+0.068, p = 0.02) than girls drinking none, as did girls drinking 2 servings/d (+0.09, p = 0.06) or 3+ servings/d (+0.08, p = 0.06). Analyses of year-to-year change in beverage intakes provided generally similar findings; boys who increased consumption of sugar-added beverages from the prior year experienced weight gain (+0.04 kg/m(2) per additional daily serving, p = 0.01). Children who increased intakes by 2 or more servings/d from the prior year gained weight (boys: +0.14,p = 0.01; girls +0.10,p = 0.046). Further adjusting our models for total energy intake substantially reduced the estimated effects, which were no longer significant.Discussion: Consumption of sugar-added beverages may contribute to weight gain among adolescents, probably due to their contribution to total energy intake, because adjustment for calories greatly attenuated the estimated associations.
