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.
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.
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.
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.
本调查旨在确定家庭食物环境中与水果和蔬菜（F&V）消费在理论上相关的微观层面的建筑和社会文化特征。
我们研究了来自美国东南部的农村家庭（n = 298）。分层多元回归分析确定了结果变量（F&V消费）与家庭食物环境的微观层面的建筑和社会文化特征之间的关联。
第1步纳入人口统计学特征，其解释了蔬菜消费中14%的方差变异以及水果消费中9%的方差变异。在第2步纳入家庭食物环境中的社会文化因素，如养育方式等后，蔬菜消费的总方差变异解释增加了25%，水果消费的总方差变异解释增加了12%。第3步纳入家庭中F&V可得性等微观层面的建筑环境因素，模型对蔬菜消费的总方差变异解释为67%，F(17, 111) = 13.5，p <.001，对水果消费的总方差变异解释为57%，F(17, 160) = 12.5，p <.001。
F&V可得性是影响儿童F&V消费的最重要变量。农村低收入家庭中存在一些可改变的因素，可作为改善F&V消费的优先干预重点。
