Understanding Alignment to the Mediterranean-Style and DASH Eating Patterns and Assessing Associations with Cardiometabolic Clinical Outcomes Among Hispanic/Latine Adults in the United States: An NHANES Analysis

Background/Objectives: The Mediterranean (Med)-style and Dietary Approaches to Stop Hypertension (DASH) eating patterns are evidence-based nutrition interventions given their protective effects from cardiometabolic diseases. Little is known about adherence to each eating pattern among the Hispanic/Latine population. The objective of this cross-sectional analysis is to assess the alignment of reported dietary intakes of Hispanic/Latine adults to Med-style and DASH eating patterns and associations with clinical outcomes for diabetes mellitus and cardiovascular diseases. Methods: A sample of 5406 Hispanic/Latine adults from the National Health and Nutrition Examination Survey (2007–2018) was utilized. Alignment to the Med-style and DASH eating patterns was calculated by scoring indices tailored for overconsumption in the United States. Multiple linear regression determined associations between each respective eating pattern and clinical outcomes. Results: Hispanic/Latine adults in the United States have a mean DASH score of 11.2 and a Med-style score of 8.4 (out of 100), indicating poor alignment. Adjusted regression analysis showed increased alignment of both eating patterns was associated with a decrease in average blood pressure (DASH ꞵ = −0.095, p = <0.0001; Med-style: ꞵ = −0.128, p = 0.0002). Greater adherence to a Med-style eating pattern score was also associated with improved average hemoglobin A1c (ꞵ −0.007, p = 0.017). Neither diet pattern score was associated with total cholesterol. Conclusions: Evidence of low alignment to the Med-style and DASH eating patterns among Hispanic/Latine populations exacerbates the need for future work to understand cultural tailoring of evidence-based eating patterns to increase adherence and support improved cardiometabolic outcomes.
