Knowledge of Sugar Content of Sports Drinks is Not Associated with Sports Drink Consumption
Purpose. To examine U.S. adult knowledge of the sugar content of sports drinks and whether this knowledge and other characteristics are associated with their sports drink consumption. Design. Nonexperimental. Setting. Nationally representative 2011 Summer ConsumerStyles survey data. Subjects. 3929 U.S. adults. Measures. The outcome variable was sports drink consumption in the past 7 days. The main exposure variable was knowledge about sports drinks containing sugar. The covariates were sociodemographic characteristics, physical activity, and weight status. Analysis. Multivariable logistic regression analysis was used to estimate adjusted odds ratios (ORs) for adults consuming sports drinks =1 times/wk after controlling for other characteristics. Results. Approximately 22% of adults reported consuming sports drinks =1 times/wk. Most adults (71% agreed that sports drinks contain sugar; however, this agreement was not significantly associated with adults' sports drink consumption. The odds of drinking sports drinks =1 times/wk were significantly higher among younger adults aged 18 to 64 years (OR range: 5.46 2.71) males (OR 2.09) high school graduates (OR 1.52) and highly active adults (OR 2.09) Conclusion. There were disparities in sports drink consumption by sociodemographic characteristics and physical activity level; however, knowledge of sports drinks' sugar content was not associated with consumption. Understanding why some population groups are higher consumers may assist in the development of education, providing those groups with a better understanding of sports drinks' nutritional value and health consequences of excessive sugar consumption in any form.
