The purpose of this study was to assess the effects of a pilot community-based behavioral intervention on the home food environment in U.S. households. Parents (21 females, 2 males; age = 36 ± 5.5 years; 78% Hispanic) of elementary school-aged children attended a 10-week dietary improvement behavioral intervention targeting an increase in fruit and vegetable consumption and a reduction in sugar intake. Home food availability of fruit, vegetables, and sugar-laden foods and beverages were assessed before and after the intervention using a modified version of the Home Food Inventory. Relative to baseline, the intervention resulted in significant increases in fruit availability (7.7 ± 3.2 items vs. 9.4 ± 3.1 items; = 0.004) and low sugar cereal (2.3 ± 1.4 types vs. 2.7 ± 1.4 types; = 0.033). There was a significant reduction in sugar-sweetened beverage availability (3.2 ± 1.9 types vs. 1.7 ± 1.3 types; = 0.004). There was a significant increase in the number of households with accessible ready-to-eat vegetables and fruit, and a significant reduction in available prepared desserts, and candy ( < 0.01). There were no significant changes in the availability of vegetables and sugar-laden cereals. The current intervention resulted in positive changes in the home food environment. Further research to confirm these results in a randomized controlled trial is warranted.
本研究旨在评估一项基于社区的行为干预对美国家庭中家庭食物环境的影响。小学学龄儿童的家长（21 名女性，2 名男性；年龄=36±5.5 岁；78%为西班牙裔）参加了为期 10 周的饮食改善行为干预，旨在增加水果和蔬菜的摄入量，减少糖的摄入量。在干预前后，使用家庭食物清单的修改版评估了水果、蔬菜和含糖食物和饮料的家庭供应情况。与基线相比，干预后水果供应量显著增加（7.7±3.2 项 vs. 9.4±3.1 项；=0.004），低糖谷物（2.3±1.4 种 vs. 2.7±1.4 种；=0.033）。含糖饮料的供应量显著减少（3.2±1.9 种 vs. 1.7±1.3 种；=0.004）。可随时食用的蔬菜和水果的家庭供应量增加，准备好的甜点和糖果的供应量减少（<0.01）。蔬菜和含糖谷物的供应量没有显著变化。目前的干预措施使家庭食物环境发生了积极变化。需要进一步的随机对照试验来证实这些结果。
