Background: Hypertension is a growing health problem among youth and is one of the biggest risk factors for heart attacks and strokes later in life. The recommended first line of therapy for children with elevated blood pressure is dietary therapy, such as the Dietary Approaches to Stop Hypertension (DASH) diet. Adherence to a DASH diet can be challenging for youth as the DASH dietary pattern is high in unprocessed whole foods, which are less common in the teenage diet. Studies have shown that eating behavior changes may be more likely to occur if coupled with other healthy lifestyle behaviors. The purpose of this study is to examine whether change in dietary behaviors in a dietary intervention emphasizing the DASH diet was related to meeting recommended guidelines for two healthy lifestyle practices – adequate sleep and physical activity. Methods: This study consisted of adolescents between the ages of 11 to 18 years old that were either diagnosed with elevated blood pressure (formally known as pre-hypertension or primary stage 1 hypertension). Participants were randomized into either DASH intervention group or a Usual Care group. Anthropometric measures, physical activity level, hours of sleep, blood pressure and dietary adherence were reported at baseline and again post intervention. Physical activity and sleep measures were compared against national recommendations for adolescents and these were compared to a DASH dietary score that was calculated from each participant’s 3 day dietary recalls. Results: ANCOVA analyses were run comparing those that met versus did not meet recommendations for daily sleep and physical activity to overall calculated DASH diet score and also to four dietary indicators of dietary quality: mean daily servings of sweets and savory snacks, sugar-sweetened beverages and fruits and vegetables. The average overall DASH dietary score (range 0 to 90 with higher score = more DASH-like) was found to be 49.82 ± 12.34 in participants meeting daily physical activity requirements versus 47.37 ± 13.94 in those not meeting recommendations, which were not significantly different. For sleep, participants who met versus did not meet daily recommendations had an average DASH score of 48.78 ± 13.11 and 47.34 ± 14.34, respectively, which were not significantly different. Conclusions: The results of this study suggest that meeting recommendations for sleep and physical activity were not related to DASH dietary adherence in adolescents with elevated blood pressure participating in a dietary intervention to lower blood pressure. Those meeting physical activity recommendations did have a significantly lower sweet intake than those not meeting this recommendation. Future research should further examine whether encouraging changes in multiple lifestyle behaviors in interventions designed to lower blood pressure may have a greater favorable effect on dietary change and cardiovascular risk factors.
