The nutrition environment is associated with risk of obesity and other diet-related chronic diseases. In Baltimore's low-income areas, carryouts (locally prepared-food sources that offer food "to go") are a common source of food, but they lack a variety of healthy options for purchase.
To evaluate individuals' preferences of healthy combination meals sold at carryouts and to identify successful intervention methods to promote healthier foods in carryouts in low-income communities in Baltimore.
The study estimated the relationship between combinations of healthier entrées (turkey club, grilled chicken), beverages (diet coke, bottled water), side dishes (watermelon, side salad), price points ($5.00, $7.50), and labeling on consumers' combination meal decisions using a forced-choice conjoint analysis. Logistic regression analysis was used to determine how individuals value different features in combination meals sold in carryouts.
There was a statistically significant difference between customer preference for the two entrées, with a turkey club sandwich being preferred over a grilled chicken sandwich (p = .02). Carryout customers (n = 50) preferred water to diet soda (p < .00).
Results suggested specific foods to improve the bundling of healthy combination meals. The selection of preferred promotion foods is important in the success of environmental nutrition interventions.
营养环境与肥胖及其他饮食相关慢性病的风险有关。在巴尔的摩的低收入地区，外卖店（提供“外卖”食品的本地食品供应源）是常见的食物来源，但可供购买的健康食品种类匮乏。
评估个人对外卖店出售的健康套餐的偏好，并确定在巴尔的摩低收入社区的外卖店推广更健康食品的成功干预方法。
该研究使用强制选择联合分析估计了更健康的主菜（火鸡俱乐部三明治、烤鸡肉三明治）、饮料（健怡可乐、瓶装水）、配菜（西瓜、配菜沙拉）、价格点（5美元、7.5美元）以及标签对消费者套餐选择决定的影响。采用逻辑回归分析来确定个人如何评价外卖店出售的套餐中的不同特征。
顾客对两种主菜的偏好存在统计学显著差异，火鸡俱乐部三明治比烤鸡肉三明治更受青睐（p = 0.02）。外卖顾客（n = 50）更喜欢水而非健怡汽水（p < 0.00）。
结果表明了有助于改进健康套餐搭配的特定食物。选择受欢迎的促销食品对于环境营养干预的成功至关重要。
