简要总结
The USDA Healthy Incentives Pilot (HIP) evaluated the impact of a 30% financial incentive on fruit and vegetable intake among adult participants in the USDA Supplemental Nutrition and Assistance Program (SNAP).
详细描述
U.S. fruit and vegetable intake remains below recommendations, particularly for low-income populations. Evidence on effectiveness of financial incentives for addressing this shortfall is limited.
This study examined effects of USDA's Healthy Incentives Pilot (HIP), which offered financial incentives to Supplemental Nutrition Assistance Program (SNAP) participants for purchasing targeted fruits and vegetables (TFV).
A randomized controlled trial of HIP was conducted in Hampden County, Massachusetts. 7,500 randomly selected SNAP households received a 30% rebate on TFV purchased using SNAP benefits. The remaining 47,595 SNAP households in the county received benefits as usual. Adults in 5,076 households were randomly sampled to complete telephone surveys, including 24-h dietary recall interviews. Surveys were conducted at baseline-1-3 mo pre-implementation-and in two follow-up rounds, 4-6 mo and 9-11 mo post-implementation. 2,784 adults (1,388 HIP, 1,396 non-HIP) completed baseline interviews; data were analyzed for 2,009 adults (72%) also completing at least one follow-up interview.

结局指标
主要结局
Targeted fruit and vegetable (TFV) intake
时间窗: Intake in prior 24 hours; assessed in two follow-up rounds (4-6 mo and 9-11 mo post-implementation) with 10% replicate subsample in each round; data pooled across two follow-up rounds and replicate samples for primary analysis
Daily adult intake of fresh, canned, frozen, and dried fruits and vegetables without added sugars, fats, oils, or salt, excluding white potatoes, mature legumes (dried beans and peas), and 100% juice. In total and by USDA food pattern group (all targeted fruits; citrus, melon, and berries; other fruits; all targeted vegetables; dark green vegetables; red \& orange vegetables (including tomatoes and other red \& orange vegetables); starchy vegetables (excluding white potatoes); and other vegetables.) Assessed via computer-assisted telephone interview 24-hour dietary recall (Automated Multiple Pass Method). Measured in cup-equivalents based on USDA Food Pattern Equivalents Database (FPED). Secondary analyses assessed changes between follow-up rounds.
