Diet Quality of Stroke Survivors Versus Neurologically Intact US Adults

Abstract

Stroke is a leading cause of disability in the US, often altering one's ability to access and consume food. The aim of the present study was to characterize and evaluate predictors of stroke survivors' diet quality (DQ). A cross-sectional evaluation of 2011-2018 National Health and Nutrition Examination Survey data is presented. Stroke survivors (n = 632) were matched for age, gender, and race with neurologically intact controls (n = 913). Food group intake, key nutrient intake, and Healthy Eating Index (HEI)-2015 scores were calculated from two 24-hour recalls and evaluated in relation to history of stroke, education, presence of a partner in the home, and income. Group differences in and predictors of DQ were evaluated with weighted independent samples t-tests and linear regression. Stroke survivors had lower intakes of vegetables, dairy, seafood and plant proteins, and unsaturated fats, and lower total HEI-2015 scores (P < 0.05). Having more education, a partner in the home, and higher income were overall positive predictors of DQ. DQ factors emphasized in heart-healthy diets were low in stroke survivors. Interventions may better address barriers to healthy eating post-stroke by incorporating educational, financial, and social support components.
