Availability and accessibility of foods in the home influence dietary behaviors. However, much of the literature involving measurement of the home food environment (HFE) has examined only self-reported data, and home food inventory tools have not been used to assess behavior change intervention efficacy. Thus, this quasi-experimental study was conducted to test the preliminary efficacy of a 10-week dietary behavioral intervention on the HFE, measured through the presence of fruits, vegetables, and sources of sugars in the household. Participants included 23 parents (21 females; age=36±5.5) of children 6-11 years old living in an ethnically diverse community within a Southwestern metropolitan area. Sociodemographic information was collected at baseline using a survey. A modified version of the Home Food Inventory was completed in the homes of participants by trained research assistants at baseline and following termination of the intervention. Relative to baseline, the intervention resulted in significant increases in availability of different types of fruits (7.7±3.2 vs. 9.4±3.1; p=0.004) and high fiber/low sugar cereal (2.3±1.4 vs. 2.7±1.4; p=0.033). There was a significant reduction in availability of sugar-sweetened beverages (3.2±1.9 vs. 1.7±1.3; p=0.004), and an increase in the number of households with accessible 100% fruit juice (3 vs. 17 households; p=0.001) and bottled/contained water (9 vs. 22 households; p<0.001). Moreover, there were meaningful changes in the number of households with accessible chocolate milk (7 vs. 0), strawberry milk (3 vs. 0), and diet soda pop (2 vs. 0). There was a significant increase in the number of households with accessible ready-to-eat vegetables (8 vs. 19 households; p=0.007), and ready-to-eat fruit (8 vs. 17; p=0.022), and a significant reduction in available prepared desserts (3.0±2.0 vs. 1.7±1.3; p=0.005), and candy (2.0±1.7 vs. 0.6±0.7; p<0.001). There were no significant changes in availability of vegetables and sugar-laden cereals, or accessibility of fresh fruit, fresh vegetables, dry cereal, candy, soda pop, desserts, and sports/fruit drinks. Overall, results suggest that the current dietary behavior change intervention resulted in positive changes in the HFE. Further research to confirm these results in a randomized controlled trial is warranted.
