We examined the association between neighborhood demographic factors and fruit and vegetable consumption among a population of low-income postpartum immigrant (foreign born) and native born women. We additionally tested whether there was a cross-level interaction between nativity status and neighborhood proportion of the foreign born population. We geocoded residential addresses of 641 low-income predominantly Latina and White women aged 18 to 45 years enrolled in an intervention trial and matched them to 184 census tracts. This data was then merged with Census data containing tract-level demographic and socioeconomic measures. Finally, we combined the tract-level data with individual level data collected through the intervention trial. Multilevel models were used to account for the multilevel structure of the data. After adjusting for multiple individual and tract level factors, for each increment of 10% of the foreign born population, we observed a statistically significant (p<.05) increase in 1/3 serving of fruit and vegetable intake. For each increase of 10% of the Black proportion of the population, a statistically significant (p<.05) decrease of 1/5 of a serving was demonstrated. Those who were foreign born and lived in neighborhoods with higher proportions of foreign born demonstrated a stronger association than native born individuals who lived in comparable neighborhoods. Among this population of low-income postpartum women, neighborhood demographics, specifically proportion of foreign born and proportion of the Black population, mattered above and beyond individual level characteristics. Food policy and programs aimed toward low-income women would benefit from considering the influence of residential environments on diet.
