This study, based on survey data from Brazilian adolescents, found no association between overweight/obesity and the Dietary Approaches to Stop Hypertension (DASH) diet score. Even adolescents with higher conformity to the DASH diet were found to have low consumption of protective foods and high consumption of health-risk foods.
Background & aims: Childhood and adolescent obesity is one of the most important issues in the global health of the population and has been increasing dramatically in recent decades. The aim of this study was to evaluate the association between overweight/obesity and the Dietary Approaches to Stop Hypertension (DASH) diet score in a representative sample of Brazilian adolescents. Methods: Data from the Study of Cardiovascular Risks in Adolescents (ERICA), a national school-based survey, were used. A total of 71,553 adolescents (12-17 years old), of both sexes, participated in the study; they had their anthropometric measurements taken and responded to a 24-h dietary recall. Eight food components of the DASH score were evaluated. 1) fruits (except fruit juices), 2) vegetables (except potatoes and beans), 3) pulses/nuts, 4) whole grains, 5) low-fat and diet/light dairy products, 6) sodium, 7) red and processed meats, and 8) sugary drinks and fruit juices. A higher score was indicative of greater accordance with the DASH diet, with a final score ranging from eight to 40 points. The association between overweight/obesity and the DASH score was assessed using Poisson regression models. Results: The highest prevalence of overweight/obesity was observed among boys aged 12-14 years (28.2%), white (27.7%), enrolled in private schools (32.4%) and among those who practiced >= 300 min physical activity/week (26.1%). The food groups most frequently consumed were sugary drinks, pulses and nuts, and red and processed meats. No association was found between overweight/obesity and the DASH diet score in Brazilian adolescents, in the adjusted analysis models. Conclusions: Low consumption of foods considered protective and high consumption of health-risk foods, even among adolescents with greater accordance with the DASH diet, may have contributed to these findings. Public health measures are needed to prevent/reduce the prevalence of overweight/ obesity in adolescence, as it is a risk for overweight/obesity in adulthood as well as other complications, leading to loss of quality of life for the individual and increased health spending.
