We assessed whether households' participation in the Supplemental Nutrition Assistance Program (SNAP) was associated with improvements in well-being, as indicated by lower rates of psychological distress.
We used longitudinal data for 3146 households in 30 states, collected between October 2011 and September 2012 for the SNAP Food Security survey, the largest longitudinal national survey of SNAP participants to date. Analyses compared households within days of program entry to the same households approximately 6 months later. We measured psychological distress in the past 30 days on a 6-item Kessler screening scale and used multivariable regression to estimate associations between SNAP participation and psychological distress.
A smaller percentage of household heads exhibited psychological distress after 6 months of participation in SNAP than at baseline (15.3% vs 23.2%; difference = -7.9%). In adjusted models, SNAP participation was associated with a decrease in psychological distress (adjusted relative risk = 0.72; 95% confidence interval = 0.66, 0.78).
Continuing support for federal nutrition programs, such as SNAP, may reduce the public health burden of mental illness, thus improving well-being among vulnerable populations.
我们评估了家庭参与补充营养援助计划（SNAP）是否与幸福感的提升相关，幸福感提升的指标是心理困扰发生率降低。
我们使用了来自30个州的3146户家庭的纵向数据，这些数据于2011年10月至2012年9月期间收集，用于SNAP食品安全调查，这是迄今为止规模最大的关于SNAP参与者的全国性纵向调查。分析比较了项目进入当天的家庭与大约6个月后的同一家庭。我们使用6项凯斯勒筛查量表测量过去30天内的心理困扰，并使用多变量回归来估计SNAP参与与心理困扰之间的关联。
参与SNAP 6个月后，户主出现心理困扰的比例低于基线水平（15.3%对23.2%；差异=-7.9%）。在调整模型中，SNAP参与与心理困扰的减少相关（调整后的相对风险=0.72；95%置信区间=0.66，0.78）。
持续支持诸如SNAP之类的联邦营养计划可能会减轻精神疾病的公共卫生负担，从而改善弱势群体的幸福感。
