In the USA, community-based food pantries provide free groceries to people struggling with food insecurity. Many pantries obtain food from regional food banks using an online shopping platform. A food bank introduced a visible nutrition rank (i.e. green, yellow or red) onto its platform. The hypothesis was that pantry orders would increase for the healthiest options (green) and decrease for the least healthy options (red).
Interrupted time series (ITS) analysis of a natural experiment. Monthly data included nutrition ranks of available inventory and itemised records of all products ordered during the 15-month baseline period and 14-month intervention.
A New England food bank.
The twenty-five largest food pantries in the network based on pounds of food ordered.
Descriptive analyses of 63 922 pantry ordering records before and after the visible ranks identified an increase in the proportion of green items ordered (39·3-45·4 %) and a decrease in the proportion of red items ordered (10·5-5·1 %). ITS analyses controlling for monthly changes in inventory available and pantry variables indicated that average monthly orders of green items increased by 1286 pounds (P < 0·001) and red orders decreased by 631 pounds (P = 0·045). Among the largest changes were increases in orders of fresh produce, brown rice, low-fat dairy and low-fat meats and decreases in orders of sugary juice drinks, canned fruit with added sugar, higher fat dairy and higher fat meats.
This promising practice can support system-wide efforts to promote healthier foods within the food banking network.
在美国,社区食品储藏室向那些面临粮食不安全问题的人提供免费食品杂货。许多食品储藏室通过在线购物平台从地区食品银行获取食品。一家食品银行在其平台上引入了可见的营养等级(即绿色、黄色或红色)。假设食品储藏室的订单会增加最健康的选择(绿色),减少最不健康的选择(红色)。
自然实验的中断时间序列(ITS)分析。每月数据包括可用库存的营养等级和 15 个月基线期和 14 个月干预期内所有订购产品的细目记录。
新英格兰食品银行。
根据订购食品的磅数,该网络中 25 家最大的食品储藏室。
在可见等级前后的 63922 个食品储藏室订购记录的描述性分析表明,订购的绿色物品比例增加(39.3-45.4%),订购的红色物品比例减少(10.5-5.1%)。控制库存和食品储藏室变量每月变化的 ITS 分析表明,绿色物品的平均每月订单增加了 1286 磅(P<0.001),红色订单减少了 631 磅(P=0.045)。最大的变化是增加了新鲜农产品、糙米、低脂乳制品和低脂肉类的订单,减少了含糖果汁饮料、加糖罐装水果、高脂肪乳制品和高脂肪肉类的订单。
这种有希望的做法可以支持整个食品银行系统努力在食品银行网络内推广更健康的食品。
