Background: The prevalence of hypertension (HTN) and elevated blood pressure (BP) in adolescents is a growing health concern. Lifestyle modifications including diet and exercise are the first line approach for adolescents with elevated BP. It is now recommended that clinicians provide advice on the Dietary Approaches to Stop Hypertension (DASH) diet at the time of diagnosis of elevated BP or HTN. Identifying eating patterns and certain food or food groups that promote satiety without significantly increasing overall energy intake is important for promoting healthful eating patterns, such as the DASH diet. Evidence regarding the relationship between satiety and the DASH diet (and target health outcomes) is minimal. This study sought to examine the relationship between satiety, as measured by Fullness Factor (FF), and change in DASH score, dietary intake, blood pressure measurements, and BMI in teens after a dietary intervention. Methods: This study is a secondary analysis of the DASH-4-Teens study conducted by Couch et al (2021). The parent study was a randomized clinical trial conducted at the Hypertension Center at Cincinnati Children’s Hospital Medical Center that assessed the post-intervention and 18-month follow-up effects of a 6-month (DASH)-focused behavioral nutrition intervention on blood pressure (BP) and endothelial function in adolescents with elevated BP. For the secondary analysis, the relationship between the calculated post-intervention FF and change (baseline to 6-months post-intervention) in dietary quality, blood pressure, and BMI status was examined. Results: Per analysis of covariance (ANCOVA), post intervention FF was positively correlated to change in DASH score (p = 0.01) and dietary fiber intake (p = 0.04) and negatively correlated to change in saturated fat intake (p = 0.03). There were negative trends observed between FF and change in energy intake (p = 0.10) and change in total fat intake (p = 0.06). A positive trend observed between FF and change in vegetable (p = 0.09) intake. There were no significant relationships observed between FF and change in blood pressure measurements or BMI. Conclusion: Results from this study indicate that adolescent satiety may be related to their ability to change their diet in a favorable direction to be more DASH-like (lower fat, higher fiber and vegetables). These findings suggest that dietary strategies to enhance satiety in adolescents with hypertension may promote improved adherence to a DASH diet. Additional research is needed to further explore the relationship between FF and other dietary components such as sugar and sodium intake and to determine if a higher satiating diet can contribute to improvement in target health outcomes.
