To compare the association of participation in Supplemental Nutrition Assistance Program (SNAP) alone . in combination with Head Start (HS), Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) or both on household dietary environment (HDE) indicators: food security, nutrition security, healthfulness choice, dietary choice, perceived food store availability, utilisation barriers and healthy food access barriers in families with young children.
This study, part of SNAP-Ed Nebraska's Needs and Assets Assessment 'Healthy People, Healthy State', utilised a cross-sectional design. HDE indicator means were compared across the federal assistance program (FAP) participation groups using multivariate ANCOVA, controlling for significant demographics, with Benjamini-Hochberg-adjusted values compared with = 0·05.
Nebraska's low-income households.
Households ( 821) with at least one child aged 2-6 years participating in SNAP-only ( 257), SNAP + HS ( 349), SNAP + WIC ( 132) and SNAP + WIC + HS ( 83).
Compared with other groups, SNAP + HS reported comparatively higher levels of household food security, whereas SNAP + HS + WIC reported lower levels ( < 0·01). SNAP + HS also showed higher levels of nutrition security, dietary choices, perceived availability of healthy foods in stores, fewer healthy food access and utilisation barriers ( < 0·05).
The findings support recent joint policy changes by Administration for Children and Families and Food and Nutrition Service, facilitating SNAP households' access to HS. HS performance standards for nutrition and family engagement can serve as a model for creating healthy HDE. Future research should employ quasi-experimental or longitudinal designs to establish causal relationships between FAP participation and HDE outcomes.
比较单独参与补充营养援助计划（SNAP），以及与“启智计划”（HS）、妇女、婴儿和儿童特别补充营养计划（WIC）联合参与或同时参与这两项计划，对幼儿家庭饮食环境（HDE）指标的影响，这些指标包括食品安全、营养安全、健康选择、饮食选择、感知食品店可及性、利用障碍和健康食品获取障碍。
本研究是SNAP-Ed内布拉斯加州需求与资产评估“健康人群，健康州”的一部分，采用横断面设计。使用多变量协方差分析比较联邦援助计划（FAP）参与组之间的HDE指标均值，控制显著的人口统计学因素，并将经本雅明尼-霍赫伯格校正的值与α = 0·05进行比较。
内布拉斯加州的低收入家庭。
821户家庭，家中至少有一名2至6岁儿童，分别单独参与SNAP（257户）、SNAP + HS（349户）、SNAP + WIC（132户）以及SNAP + WIC + HS（83户）。
与其他组相比，SNAP + HS报告的家庭食品安全水平相对较高，而SNAP + HS + WIC报告的水平较低（P < 0·01）。SNAP + HS还显示出更高的营养安全水平、饮食选择、商店中健康食品的感知可及性，以及更少的健康食品获取和利用障碍（P < 0·05）。
研究结果支持儿童与家庭管理局和食品与营养服务局最近的联合政策变化，即便利SNAP家庭参与HS。HS的营养和家庭参与绩效标准可作为创建健康HDE的典范。未来研究应采用准实验或纵向设计，以确定FAP参与与HDE结果之间的因果关系。
