Objective: To evaluate the predictive validity of a home food environment (HFE) questionnaire to assess overall diet quality as measured by DASH score and fruit and vegetable intake in adolescents with elevated blood pressure. Method: A total of 96 adolescents aged 11-18 years with a diagnosis of pre-hypertension or stage 1 hypertension, newly enrolled in the Cincinnati Children’s Hypertension Treatment Center were enrolled in this study. All participants were given a HFE questionnaire, which consisted of five scales that assessed psychosocial and physical aspects of the home environment related to eating. These scales were derived from previously published scales that were used to assess fruit and vegetable intake in healthy adolescents. All scales were scored with a 5 point Likert scale ranging from 1 (low/never) to 5 (high/frequently), except parent rules related to eating which, were summed and averaged, with a higher score indicating a greater use of food rules in the home. Weight and height were measured at the Center using standard procedures. Demographics were self-reported. Dietary intake data were collected with three random 24-hour dietary recalls by trained registered dietitians and then analyzed using the Minnesota Nutrient Data System for Research software. Multiple regression models were run to assess the associations between HFE scales and diet quality. Results: The study sample was 65.6 % male and 98.9 % non-Hispanic white; the prevalence of overweight/obesity (BMI =85th percentile for age and gender) was 83.3%. Scale scores for healthy home food availability, parenting rules around eating, and frequency of eating family meal together were positively associated with participants’ DASH score when adjusted for age, gender, race, BMI z-score, and energy intake (p<0.05). Scale scores for healthy home food availability and parenting rules around eating were also positively associated with participants’ fruit intake when adjusted for age, gender, and race (p<0.05). Frequency of fast food/carry-out was negatively associated with participants’ DASH score and fruit intake when adjusted for age, gender, race, BMI z-score, and energy intake (p<0.05). Family food insecurity was not associated with diet quality indexes. There was no significant association between HFE scales and vegetable intake servings. Conclusion: Several scales on the HFE questionnaire used in this study had good predictive validity to assess fruit intake and DASH score among adolescents with elevated blood pressure. Specifically, scales for healthy home food availability, parenting rules around eating, frequency of eating family meals together, and frequency of fast food/take out predicted DASH score and/or fruit intake, which confirms the validity of these scales in this population. More research is needed to determine factors within the home food environment that predict vegetable consumption in this at risk population.
