Abstract: Purpose.To evaluate the effectiveness of a nutrition intervention based on the Social Cognitive Theory (SCT) emphasizing fruits, vegetables, and low fat dairy products, and low fat, low sodium foods (DASH) on changing dietary knowledge, self-efficacy and intake in adolescents with hypertension.Methods.46 adolescents with hypertension were randomly assigned to the DASH intervention (n=23) or a one time meeting with a dietician (usual care, n=23).Diet, knowledge, and self-efficacy were assessed before and after the 3 month treatment.Results.After the intervention, diet-related knowledge was greater in the DASH group versus the usual care group, and there was a trend for a greater gain in self-efficacy in the DASH group.Also, the DASH participants had a greater increase in fruits, vegetables and low-fat diary products, and a greater reduction in high fat, high sodium foods as compared to the usual care group. Conclusion.A nutrition intervention emphasizing fruits, vegetables and low-fat diary products and based on the theoretical concepts of the SCT resulted in improvements in diet quality, knowledge, and self-efficacy in adolescents with hypertension.
