Weekly consumption of sports drinks and energy drinks among adolescents is significantly associated with higher consumption of other sugar-sweetened beverages, cigarette smoking, and screen media use, according to a study in the Journal of Nutrition Education and Behavior conducted by researchers from the University of Minnesota and Duke University.
The study was undertaken to build understanding of health
behavior patterns related to adolescent consumption of sports and energy drinks
and inform intervention strategies to reduce consumption of these
sugar-sweetened beverages. Although national data have shown a decline in the
prevalence of soft drink and fruit drink consumption, sports and energy drink
consumption has tripled among adolescents in recent years. The high caffeine
content of energy drinks, as well as the high sugar and calorie content of many
sports and energy drinks, has drawn much concern from health professionals
Data for the study were gathered from 20 public middle
schools and high schools in the Minneapolis-St. Paul metropolitan area of
Minnesota as part of the population-based study, Eating and Activity in Teens
(EAT 2010). Surveys and anthropometric measures were completed by 2,793
adolescents during the 2009–2010 school year. Mean age of the participants was
14.4 years, participants were equally divided by gender, and 81 percent
identified as a racial/ethnic background other than non-Hispanic white.
Among the measured variables in this study were height and
weight; consumption frequency for sports drinks, energy drinks, and breakfast;
time spent engaged in physical activity, playing video games, and watching
television; and smoking status. Although sports drink consumption was linked to
higher levels of moderate-to-vigorous physical activity and sport participation,
the overall pattern of associations indicated that sports and energy drink
consumption should be addressed as part of a clustering of unhealthy behaviors
among some adolescents.
Of note, "among boys, weekly sports drink consumption
was significantly associated with higher TV viewing; boys who regularly
consumed sports drinks spent about one additional hour per week watching TV
compared with boys who consumed sports drinks less than once per week,"
said lead author Nicole Larson, PhD, MPH, RDN, Division of Epidemiology and
Community Health, School of Public Health, University of Minnesota,
Minneapolis. As another example, "boys who consumed energy drinks at least
weekly spent approximately four additional hours per week playing video games
compared to those who consumed energy drinks less than once per week."
