Dietary patterns consisting of combinations of food used to represent overall nutrient intake, have recently been used to better capture the overall nutritional habits of an individual and their effects on risk of cardiovascular disease. Relationships between neighborhood and individual level covariates and dietary patterns have not been examined in an African American (AA) population. Using multilevel modeling, we examined cross‐sectional relationships between neighborhood socio‐economic factors, availability of fast food restaurants and previously defined dietary patterns, while adjusting for age, sex, education, BMI, smoking status, and physical activity. The three dietary patterns, derived via factor analysis, used in this analysis are named “southern,” “fast food,” and “prudent.” Two neighborhood factors were inversely associated with the prudent diet, including the density of the AA population (p=0.02), and a summary index measure of neighborhood advantage (higher scores correspond to greater neighborhood advantage) (p<0.001). This advantage index is also inversely associated with the southern dietary pattern (p=0.03). Of particular interest is that we saw no neighborhood‐level covariate associations, including proximity to fast food restaurants, with the fast food pattern, suggesting that proximity to fast food restaurants may not influence dietary intake in this population.
