Methods
This is a cross-sectional study using data from the National Health and Nutrition Examination Survey (NHANES) 1999-2004, a complex sample survey designed to collect data on the health and nutrition from a representative household population in the United States.18 Certain populations, such as adolescents and racial/ethnic minorities, were oversampled to improve estimates in these groups.
The NHANES protocol was reviewed and approved by the National Center for Health Statistic's Institutional
Results
Demographic and clinical characteristics of the study population are shown in Table I. Drinking any amount of sugar-sweetened beverages in a day was reported by 82.5% of adolescents. Adolescents who drank more sugar-sweetened beverages tended to be older and male. Sugar-sweetened beverage consumption did not differ according to race/ethnicity, BMI z-score, height z-score, or dietary fiber intake. Sugar-sweetened beverage consumption was associated with higher intake of total calories, sodium,
Discussion
Adult studies have shown serum uric acid levels to be predictive of major outcomes even when values are within the normal range.8
It should be noted that the adjusted difference in serum uric acid between the lowest and highest category of sugar-sweetened beverage consumption was relatively small. In adult studies, the risk associated with serum uric acid varies with the outcome. The observed serum uric acid difference between extreme categories, 0.18 mg/dL, in the NHANES III, was associated
