Cardiovascular damage related to HTN in adolescence predicts adverse clinical events in adulthood. Only about 10% of youth consume adequate F&V for ideal cardiovascular health.Design: This study is a secondary data analysis of a larger randomized clinical trial (RCT), which included 11 to 18 year old youth at Cincinnati Children’s Hospital Medical Center (CCHMC). Adolescents diagnosed with primary HTN or pre-HTN between the years 2008-2015 were enrolled in a hospital-based dietary intervention (Dietary Approaches to Stop Hypertension or DASH-4-Teens or Usual Care) to lower blood pressure (BP).Methods: Multiple linear regression analysis, adjusted for relevant confounders, was used to assess the relationship between meal timing and frequency of eating occasions (EO) and intake of fruits and vegetables (F&V), sweet and savory snacks (SSS), high calorie beverages (HCB) and DASH score (a measure of DASH diet adherence) in adolescents with pre-HTN and HTN participating in the DASH-4-Teens intervention and Usual Care.Outcome: Servings of F&V (p=0.0004), SSS (p=0.03) and DASH score (p=0.03) were positively associated with eating frequency (=3.0, >3.0-4.0, >4.0-5.0, and >5.0 EOs). Servings of F&V (p<0.0001) and HCB (p<0.0001) were positively associated with diurnal meal time intervals (6am-10:59am, 11am-3:59pm, and 4pm-8:59pm), compared to nocturnal meal time interval (9pm-5:59am).Relevance: Increased frequency of diurnal eating was related to increased F&V intake, but also increased intake of SSS and HCB consumption. These findings suggest that grazing throughout the day may be a beneficial strategy to meeting DASH goals as long as guidance is given in regards to healthy snack and beverage choices. It is recommended to substitute F&V for SSS and low-fat milk for HCB to derive the most benefit from DASH on lowering BP. 2018-11-02 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1535469261699629 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1535469261699629 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
