Food insecurity, the inability to acquire adequate food due to insufficient resources for food, is associated with an increased risk for obesity and associated health problems. This study assessed the feasibility and initial efficacy of a prefilled online grocery shopping cart (i.e., default option) in promoting healthier grocery purchases in individuals with food insecurity. Fifty participants recruited from food pantries in New York in 2018 were randomized to review nutrition information before purchasing groceries online (n = 23) or modify a prefilled, nutritionally balanced online shopping cart (n = 27) based on a budget corresponding to Supplemental Nutrition Assistance Program benefits. Compared to nutrition education, the default shopping cart resulted in the purchase of significantly more ounces of whole grains (Mean Difference [Mdiff] = -4.05; 95% Confidence Interval [CI] = -6.14, -1.96; p < .001), cups of fruits (Mdiff = -1.51; 95% CI = -2.51, -0.59; p = .002) and vegetables (Mdiff = -2.21; 95% CI = -4.01, -0.41; p = .02), foods higher in fiber (mg; Mdiff = -15.65; 95% CI = -27.43, -3.87; p = .01), and lower in sodium (mg; Mdiff = 1642.66; 95% CI = 660.85, 2624.48; p = .002), cholesterol (mg; Mdiff = 463.86; 95% CI = 198.76, 728.96; p = .001), and grams of fat (Mdiff = 75.42; 95% CI = 42.81, 108.03; p < .001) and saturated fat (Mdiff = 26.20; 95% CI = 14.07, 38.34; p < .001). The use of a default online shopping cart appears to improve nutritional quality of food purchases in individuals facing financial constraints.

在线杂货店购物时轻推：一项旨在增强粮食不安全个体营养的随机可行性试验

粮食不安全，即由于食物资源不足而无法获得足够的食物，与肥胖和相关健康问题的风险增加有关。本研究评估了预装在线杂货购物车（即默认选项）在促进食品不安全个人购买更健康杂货方面的可行性和初步功效。2018 年从纽约食品储藏室招募的 50 名参与者被随机分配在线购买杂货之前查看营养信息（n = 23）或根据与补充营养援助相对应的预算修改预装的、营养均衡的在线购物车（n = 27）计划福利。与营养教育相比，默认购物车导致购买更多盎司的全谷物（平均差异 [Mdiff] = -4.05；95% 置信区间 [CI] = -6.14, -1.96；p < .001）、水果杯（Mdiff = -1.51; 95% CI = -2.51, -0.59; p = .002) 和蔬菜 (Mdiff = -2.21; 95% CI = -4.01, -0.41; p = .02), 高纤维食物 (mg; Mdiff = -15.65；95% CI = -27.43、-3.87；p = .01），钠含量较低（mg；Mdiff = 1642.66；95% CI = 660.85、2624.48；p = .002）、胆固醇（mg； Mdiff = 463.86；95% CI = 198.76, 728.96；p = .001），脂肪克数（Mdiff = 75.42；95% CI = 42.81, 108.03；p < .001）和饱和脂肪（Mdiff = 296.001） CI = 14.07, 38.34；p < .001）。使用默认的在线购物车似乎可以改善面临财务限制的个人购买食品的营养质量。95% 置信区间 [CI] = -6.14, -1.96; p < .001)、水果杯 (Mdiff = -1.51; 95% CI = -2.51, -0.59; p = .002) 和蔬菜 (Mdiff = -2.21; 95% CI = -4.01, -0.41; p = .02）、纤维含量较高的食物（mg；Mdiff = -15.65；95% CI = -27.43、-3.87；p = .01）和钠含量较低的食物（mg；Mdiff = 1642.66；95% CI = 660.85、2624.48 ；p = .002）、胆固醇（mg；Mdiff = 463.86；95% CI = 198.76、728.96；p = .001）和脂肪克数（Mdiff = 75.42；95% CI = 42.81、108.03；p < . ) 和饱和脂肪 (Mdiff = 26.20; 95% CI = 14.07, 38.34; p < .001)。使用默认的在线购物车似乎可以改善面临财务限制的个人购买食品的营养质量。95% 置信区间 [CI] = -6.14, -1.96; p < .001)、水果杯 (Mdiff = -1.51; 95% CI = -2.51, -0.59; p = .002) 和蔬菜 (Mdiff = -2.21; 95% CI = -4.01, -0.41; p = .02）、纤维含量较高的食物（mg；Mdiff = -15.65；95% CI = -27.43、-3.87；p = .01）和钠含量较低的食物（mg；Mdiff = 1642.66；95% CI = 660.85、2624.48 ；p = .002）、胆固醇（mg；Mdiff = 463.86；95% CI = 198.76、728.96；p = .001）和脂肪克数（Mdiff = 75.42；95% CI = 42.81、108.03；p < . ) 和饱和脂肪 (Mdiff = 26.20; 95% CI = 14.07, 38.34; p < .001)。使用默认的在线购物车似乎可以改善面临财务限制的个人购买食品的营养质量。纤维含量较高的食物（mg；Mdiff = -15.65；95% CI = -27.43, -3.87；p = .01），而钠含量较低（mg；Mdiff = 1642.66；95% CI = 660.85, 2624.48；p = . 002)、胆固醇（mg；Mdiff = 463.86；95% CI = 198.76、728.96；p = .001）和脂肪克数（Mdiff = 75.42；95% CI = 42.81、108.03；p < .001）和饱和脂肪（Mdiff = 26.20；95% CI = 14.07, 38.34；p < .001）。使用默认的在线购物车似乎可以改善面临财务限制的个人购买食品的营养质量。纤维含量较高的食物（mg；Mdiff = -15.65；95% CI = -27.43, -3.87；p = .01），而钠含量较低（mg；Mdiff = 1642.66；95% CI = 660.85, 2624.48；p = . 002)、胆固醇（mg；Mdiff = 463.86；95% CI = 198.76、728.96；p = .001）和脂肪克数（Mdiff = 75.42；95% CI = 42.81、108.03；p < .001）和饱和脂肪（Mdiff = 26.20；95% CI = 14.07, 38.34；p < .001）。使用默认的在线购物车似乎可以改善面临财务限制的个人购买食品的营养质量。p < .001）。使用默认的在线购物车似乎可以改善面临财务限制的个人购买食品的营养质量。p < .001）。使用默认的在线购物车似乎可以改善面临财务限制的个人购买食品的营养质量。
