The Supplemental Nutrition Assistance Program (SNAP) is the largest federal food assistance program, providing $67 billion in benefits to 44 million Americans. Some states distribute SNAP benefits over one or a few days each month, which may create an incentive for retailers to heavily promote top-selling products, like sugar-sweetened beverages, when benefits are disbursed.
A beverage environment scan assessing presence of displays, advertisements, and price promotions for sugar-sweetened, low-calorie, and unsweetened beverages was administered in a census of SNAP-authorized beverage retailers (n=630) in three cities in New York from September to November 2011. Multilevel regression models controlling for store type; county; and percentage SNAP enrollment, poverty, and non-Hispanic white population in the store's census tract were used to estimate the odds of in-store beverage marketing during the SNAP benefit issuance period compared to other days of the month. Data were analyzed in 2016.
There were higher odds of in-store sugar-sweetened beverage marketing during SNAP benefit issuance days (first to ninth days of the month) compared with other days of the month, particularly for sugar-sweetened beverage advertisements (OR=1.66, 95% CI=1.01, 2.72) and displays (OR=1.88, 95% CI=1.16, 3.03). In census tracts with high SNAP enrollment (>28%), the odds of a retailer having sugar-sweetened beverage displays were 4.35 times higher (95% CI=1.93, 9.98) during issuance compared with non-issuance days. There were no differences in marketing for low-calorie or unsweetened beverages.
Increases in sugar-sweetened beverage marketing during issuance may exacerbate disparities in diet quality of households participating in SNAP. Policy changes, like extending SNAP benefit issuance, may mitigate these effects.
补充营养援助计划(SNAP)是最大的联邦食品援助计划,为 4400 万美国人提供了 670 亿美元的福利。一些州每月在一到几天内分配 SNAP 福利,这可能会促使零售商在发放福利时大力推广畅销产品,如含糖饮料。
在 2011 年 9 月至 11 月期间,对纽约市的三个城市中的 630 家获得 SNAP 授权的饮料零售商进行了一项饮料环境扫描调查,评估了展示、广告和价格促销活动的存在情况,这些饮料包括含糖、低热量和无糖饮料。使用多层回归模型,控制了商店类型、县、SNAP 参与率、贫困率和商店所在普查区的非西班牙裔白人人口比例,来估计在 SNAP 福利发放期间与当月其他日子相比,店内饮料营销的几率。数据于 2016 年进行了分析。
与当月其他日子相比,在 SNAP 福利发放日(月初的第 1 至 9 天),店内含糖饮料营销的几率更高,特别是含糖饮料广告(OR=1.66,95%CI=1.01,2.72)和展示(OR=1.88,95%CI=1.16,3.03)。在 SNAP 参与率较高(>28%)的普查区,与非发放日相比,零售商在发放日展示含糖饮料的几率高 4.35 倍(95%CI=1.93,9.98)。低热量或无糖饮料的营销没有差异。
在发放福利期间,含糖饮料营销的增加可能会加剧参与 SNAP 的家庭在饮食质量方面的差异。政策变化,如延长 SNAP 福利发放时间,可能会减轻这些影响。
