Increased Access to Fruits and Vegetables for DASH Diet Compliance in Immigrant Hispanic/Latinx Individuals With Hypertension

This study will utilize a phased, mixed methods approach including a literature review to inform a patient/provider survey, individual patient interviews to better understand how to develop a medically-tailored foods box for the patient population with hypertension, and an open observational study.

The proposed study will be conducted at a St. Mary's Health Clinics site in the Twin Cities metro, which includes access to the required equipment, a space to collect required measures, and designated patient rooms for participant privacy. Obese (BMI >30 kg/m2) men and women (ages 18+) diagnosed with hypertension will be recruited via flyers, email, and mail from St. Mary's Health Clinics for an open observational study. For 4 weeks, the individuals will receive supplemental, culturally-appropriate fruits and vegetables (to achieve 8-10 servings per day) supported by intensive education for chronic disease management. To address social determinants of health surrounding fruit and vegetable access, food will be provided for the patient and family members, if the participant indicates a need.

Participants will receive supplemental fruits and vegetables high in carotenoids and staple items that are promoted on a DASH Diet, with encouragement and support to consume the fruits and vegetables via recipes, samples, and weekly text/call check-ins to support utilization. Compliance will be measured via non-invasive skin carotenoid status using a Veggiemeter. Boxes will be distributed from a central site, similar to the medication pick-up structure St. Mary's Health Clinics patients are familiar with or will be delivered to the patient's preferred address, if access to the clinic is a barrier. All enrolled participants will receive education on hypertension management, which will include an interprofessional health appointment with a medical professional to discuss medication compliance, and resources from an occupational therapist for chronic disease management strategies, and 2 nutrition appointments with a Registered Dietitian regarding the DASH Diet (initial education and follow-up at 2 weeks). The interprofessional education provided is intended to yield in higher compliance to dietary changes and adherence to medication regimen. All materials and appointments will be available in Spanish and English. There will be an interpreter available for all medical appointments, as 85% of patients are non-English speaking.

All participants will be screened to ensure eligibility. Screening will include: a demographic (age, gender, race/ethnicity, smoking status, family size, and primary food preparer in the household) and medical history questionnaire to determine comorbidities. The National Cancer Institute's 19-item F/V screener will be utilized to determine regular consumption of F/V for the participant and the family, if applicable. Exclusions will be made for individuals that are taking insulin to manage diabetes mellitus, smokers, and those with a BMI <30 kg/m2. At baseline (day 0) and Day 28, cardiometabolic markers (height, weight, BP, waist circumference, and skin carotenoid status) will be collected. BP will be measured by trained professionals using random- zero sphygmomanometers while sitting down after a 5-minute rest period. Two measures will be collected and averaged. Carotenoid status will be assessed via non-invasive skin spectrometry using a VeggieMeter (Longevity Link Corporation, UT). The quantity of F/V provided in the supplemental box to achieve 8-10 servings daily will be determined during the screening.
