Dine and DASH Into Wellness Pilot Study

Excess cardiovascular disease (CVD) mortality among Black Americans with chronic kidney disease (CKD) is a significant US public health disparity. Compared to their White counterparts, Black adults develop kidney disease earlier in life, are 3 times more likely to develop kidney failure necessitating dialysis or kidney transplantation, and are 1.5 times more likely to die prematurely from CVD. Epidemiologic-based studies suggest that greater adherence to the Dietary Approaches to Stop Hypertension (DASH) diet improves markers of kidney function and cardiovascular outcomes in Black adults. Yet, adherence to the DASH diet is low among US adults. It is hypothesized that a 16-week culturally-tailored, dietitian-led coaching program enhanced with cooking classes will increase adherence to the DASH diet among Black adults who are at-risk for developing CKD. To inform the design of a future adequately powered clinical trial, investigators will determine the feasibility, acceptability, and preliminary efficacy of delivering a diet coaching program in community-based settings. In this pilot trial, participants will be recruited from the local community and randomized 1:1 to receive the 16-week diet coaching program as part of an immediate-start intervention group or a delayed-start intervention group consisting of four cohorts of 12 participants. Data collection visits will occur at baseline, 16 weeks and 32 weeks. Study data will include demographic information, healthy histories, psychosocial surveys, 24-hour dietary recalls, physical measurements and laboratory data. Rates of participant recruitment, retention, group attendance and data collection will determine feasibility. Participant satisfaction ratings will determine program acceptability.
