Adolescent consumption of sports and energy drinks: linkages to higher physical activity, unhealthy beverage patterns, cigarette smoking, and screen media use.

OBJECTIVE: To examine patterns of adolescent sports and energy drink (SED) consumption and identify behavioral correlates. DESIGN: Data were drawn from Eating and Activity in Teens, a population-based study. SETTING: Adolescents from 20 middle and high schools in Minneapolis/St Paul, MN completed classroom-administered surveys. PARTICIPANTS: A total of 2,793 adolescents (53.2% girls) in grades 6-12. VARIABLES MEASURED: Beverage patterns; breakfast frequency; moderate to vigorous physical activity (MVPA); media use; sleep; and cigarette smoking. ANALYSIS: Linear and logistic regression models were used to estimate associations between health behaviors and SED consumption, adjusting for demographics. RESULTS: Over a third of adolescents consumed sports drinks and 14.7% consumed energy drinks at least once a week. Among boys and girls, both sports and energy drink consumption were related to higher video game use; sugar-sweetened beverage and fruit juice intake; and smoking (P < .05). Sports drink consumption was also significantly related to higher MVPA and organized sport participation for both genders (P < .01). CONCLUSIONS AND IMPLICATIONS: Although sports drink consumption was associated with higher MVPA, adolescents should be reminded of recommendations to consume these beverages only after vigorous, prolonged activity. There is also a need for future interventions designed to reduce SED consumption, to address the clustering of unhealthy behaviors.
