BACKGROUND
The present study examined income-related household food purchases among a sample of 90 households from the community.
METHODS
Annotated food purchase receipts were collected for a four-week period by the primary household shopper. Receipt food source and foods items were classified into specific categories, and food quantities in ounces were recorded by research staff. For home sources, a limited number of food/beverage categories were recorded. For eating out sources, all food/beverage items were recorded. Median monthly per person dollars spent and per person ounces purchased were computed. Food sources and food categories were examined by household income tertile.
SUBJECTS AND SETTING
A community-based sample of 90 households.
RESULTS
Higher income households spent significantly more dollars per person per month from both home and eating out sources compared with lower income households ($163 versus $100, p < .001). Compared with lower income households, higher income households spent significantly more home source dollars on both fruits/vegetables (21.5 versus 10.2, p < .001) and sweets/snacks (17.3 versus 8.3, p < .001), but did not differ on home dollars spent on sugar sweetened beverages (2.0 versus 1.7, p < .46). The proportion of home beverages that were sugar sweetened beverages was significantly higher among lower income households (45% versus 26%, p < .01). Within eating out sources, lower income households spent a significantly greater percent of dollars per person at carry out places (54% versus 37%, p < .01). No income differences were observed for dollars spent at discount grocery stores, small grocery stores or convenience stores.
CONCLUSIONS
Higher income households spent more money on both healthy and less healthy foods from a wide range of sources. Lower income households spent a larger proportion of their eating out dollars at carry out places, and a larger proportion of their home beverage purchases were sugar sweetened beverages.
背景
本研究在社区中对 90 户家庭进行了样本调查，研究了家庭食品购买与收入的关系。
方法
由主要家庭购物者在四周内记录已标注的食品购买收据。研究人员将收据上的食品来源和食品项目分为特定类别，并记录以盎司为单位的食品数量。对于家庭来源，记录了有限数量的食品/饮料类别。对于外出就餐来源，记录了所有的食品/饮料项目。计算了每人每月的美元支出和每人购买的盎司数。根据家庭收入分为三个等级来考察食品来源和食品类别。
对象和地点
社区内的 90 户家庭样本。
结果
与低收入家庭相比，高收入家庭无论是从家庭来源还是外出就餐来源，每月每人的花费都明显更多（$163 比 $100，p<.001）。与低收入家庭相比，高收入家庭在家庭来源上购买水果/蔬菜的花费明显更多（21.5 比 10.2，p<.001），购买甜食/零食的花费也明显更多（17.3 比 8.3，p<.001），但在家庭来源上购买加糖甜饮料的花费没有差异（2.0 比 1.7，p<.46）。低收入家庭的家庭饮料中，加糖甜饮料的比例明显更高（45%比 26%，p<.01）。在外出就餐来源中，低收入家庭在外卖点的花费占每人花费的比例明显更高（54%比 37%，p<.01）。在折扣杂货店、小杂货店或便利店的消费上，没有观察到收入差异。
结论
高收入家庭从各种来源购买健康和不太健康的食品都花费更多。低收入家庭在外卖上的花费比例更大，家庭饮料购买中加糖甜饮料的比例也更高。
