目的：现有的数据进行了重新检查，以确定饮料消费的变化和饮料消费和BMI Z-分数之间的关联在儿童（n = 164）在两个years.Methods：饮料（牛奶，100%果汁，无糖苏打水或加糖）和总热量摄入量计算从24小时的饮食回忆。测量身高和体重以计算BMI。受试者按BMI Z评分分为正常体重、超重、体重增加和体重减轻。结果：两年内所有体重正常的受试者的牛奶摄入量均显著减少，而无糖汽水摄入量显著增加，而超重者的无糖汽水摄入量显著增加，牛奶摄入量减少，但未达到显著性水平。牛奶消费量的变化与含糖饮料消费量呈负相关。与正常体重的受试者相比，超重和体重增加的受试者的无糖汽水消费量增加明显更大。基线BMI Z-分数和第2年饮食苏打水消费预测83.1%的方差在第2年BMI Z-score.Conclusion：在饮料消费的变化，发现在这个方便的样本在两年。无糖苏打水消费是唯一与第2年BMI Z评分相关的饮料类型，与正常体重受试者相比，超重受试者和体重增加的受试者在第2年的消费量更大。在儿童和青少年中需要额外的纵向数据来检查饮料消费与BMI之间的关联，因为普通和无糖苏打水的消费已经成为一种社会规范。
Objective: Existing data was reexamined to determine changes in beverage consumption and associations between beverages consumed and BMI Z-score in children (n = 164) across two years.Methods: Beverages (milk, 100% juice, diet soda or sugar sweetened) and total caloric intake were calculated from a 24-hour diet recall. Height and weight were measured to calculate BMI. Subjects were categorized by BMI Z-score as normal weight, overweight, gained weight and lost weight. Data was collected at baseline and year 2.Results: Significant decreases in milk and increases in diet soda were found over two years in all subjects and normal weight, whereas overweight had a significant increase in diet soda consumption and a decrease in milk consumption that did not reach significance. Change in milk consumption was inversely correlated with sugar-sweetened beverage consumption. Increases in diet soda consumption were significantly greater for overweight and subjects who gained weight as compared to normal weight subjects. Baseline BMI Z-score and year 2 diet soda consumption predicted 83.1% of the variance in year 2 BMI Z-score.Conclusion: Shifts in beverage consumption were found in this convenient sample across two years. Diet soda consumption was the only type of beverage associated with year 2 BMI Z-score, and consumption was greater in overweight subjects and subjects who gained weight as compared to normal weight subjects at two years. Additional longitudinal data examining associations between beverage consumption and BMI is needed in children and adolescents, as consumption of regular and diet soda has become more of a social norm.
