BACKGROUND: This investigation sought to identify micro-level built and sociocultural characteristics of a home food environment that have been theoretically linked with fruit and vegetable (F&V) consumption. METHOD: We examined rural families (n = 298) from the southeastern United States. Hierarchical multiple regression analyses determined the association between the outcome variable (F&V consumption) and micro-level built and sociocultural characteristics of a home food environment. RESULTS: Demographic characteristics were entered at Step 1, explaining 14% of variance in vegetable consumption and 9% in fruit consumption. After entry of sociocultural factors in the home food environment, such as parenting styles and so on, in Block 2, the total variance explained increased by 25% for vegetable consumption and 12% for fruit consumption. Micro-level built environmental factors such as the availability of F&V in the home was entered at Block 3, total variance explained by the model for vegetable consumption was 67%, F(17, 111) = 13.5, p < .001, and for fruit consumption was 57%, F(17, 160) = 12.5, p < .001. CONCLUSION: F&V availability was the most important variable influencing a child's consumption of F&V. There are modifiable factors within the rural low-income home that could serve as priorities for intervention to improve F&V consumption.
