Abstract: The relationship between dietary self-monitoring and blood pressure change in adolescents with pre-hypertension or hypertension participating in a nutrition intervention emphasizing the DASH diet by Margaret GraeterObjective: Examine the relationship between dietary self-monitoring and change in blood pressure in adolescents with pre-/hypertension following a clinic-based nutrition intervention to lower blood pressure.Subjects: Adolescents 11 to 18 years of age with a clinical diagnosis of prehypertension or primary stage 1 hypertension who participated in a 3-month behavioral, nutrition intervention emphasizing the DASH diet.Methods: Adolescents were asked to monitor their dietary intake for 5 of 7 days each week for the duration of the nutrition intervention.Food trackers were reviewed be research personnel.Adolescents who went 2 weeks without mailing in a food tracker were offered a simpler goal tracking form to record their goals met.Food and goal trackers were independently coded to assess compliance to the skill of dietary selfmonitoring.Basic compliance was assessed by determining actual days of food recording, recording sufficiency, complete recording of food descriptions, and complete recording of food amounts.Category compliance was determined based on a participant's ability to categorize foods correctly into DASH food groups.Servingiii compliance was determined based on a participant's ability to calculate the number of DASH food servings from foods recorded.Baseline and 3-month blood pressures were assessed at the Cincinnati Children's Hypertension Center using standard protocol.Relative blood pressure change was calculated as 3-month blood pressure minus baseline blood pressure.Results: Over 85% of participants demonstrated excellent compliance to recording sufficiency, recording complete food descriptions and recording food amounts.Forty-six percent of participants were able to correctly classify fruits & vegetables, 21%were able to correctly classify low-fat dairy foods, and 5% were able to correctly classify DASH unfriendly foods (e.g., high fat/high sodium).Approximately half of participants (51%) demonstrated at least good proficiency in correctly calculating DASH serving amounts for low-fat dairy foods.Most demonstrated difficulty in correctly calculating DASH serving amounts for fruit & vegetables (70%) and DASH unfriendly foods (98%).
