Abstract

There was no evidence on the relationship of Dietary Approaches to Stop Hypertension (DASH) with metabolic health condition in adolescents with overweight and obesity. The purpose of this research was to investigate the association of priori-defined DASH dietary pattern with metabolic health status among adolescents with overweight and obesity in Iran. A cross-sectional survey performed on a representative sample of adolescents with overweight and obesity (n = 203). Dietary intakes were collected via a validated food frequency questionnaire and DASH score was characterized according to eight components. Data of anthropometric measures, blood pressure, circulating insulin, fasting blood sugar, and lipid profile were collected. Metabolic health status was defined based on criteria of International Diabetes Federation (IDF) and insulin resistance (IR). Based on IDF and IDF/IR criteria, 38.9% and 33.0% of adolescents suffered from metabolically unhealthy overweight/obesity (MUO). After controlling all confounders, subjects in the highest vs. lowest tertile of DASH diet had respectively 92% and 91% lower odds of MUO based on IDF definition (OR = 0.08; 95%CI 0.03–0.22) and IDF/IR criteria (OR = 0.09; 95%CI 0.03–0.29). Subgroup analysis by sex and body mass index determined that this relationship was more powerful in girls and overweight individuals. Also, in fully adjusted model, highest vs. lowest adherence to DASH diet was linked to decreased odds of hyperglycemia (OR = 0.07; 95% CI 0.03–0.21), hypertriglyceridemia (OR = 0.26; 95% CI 0.09–0.73), low HDL cholesterolemia (OR = 0.30; 95% CI 0.12–0.73) and insulin resistance (OR = 0.07; 95% CI 0.02–0.28), as metabolic health components. Greater compliance to DASH dietary pattern was linked to a remarkable lower odd of metabolic unhealthy condition among Iranian adolescents, especially in overweight subjects and girls. More prospective surveys are required to assert these results. © The Author(s) 2024.
