The nutrition environment, including food store type, may influence dietary choices, which in turn can affect risk of obesity and related chronic diseases such as CHD, diabetes and cancer. The objective of the present study was to elucidate the extent to which healthy foods are available and affordable in various rural food outlets. A subset of the nutrition environment was assessed using the Nutrition Environment Measures Survey in Stores (NEMS-S). The NEMS-S instrument assessed the availability and price of healthy foods (e.g. low-fat/non-fat milk, lean meats and reduced-fat dinner entrées) compared with less healthy counterparts (e.g. whole milk, non-lean meats and regular dinner entrées). The NEMS-S also assessed the quality of fresh fruits and vegetables. Availability, prices and quality of healthy foods were compared between grocery stores ( 24) and convenience stores ( 67) in nine rural counties in Alabama. Mean availability subscale score (possible range 0 to 30; higher score indicates a greater number of healthier foods were available) for grocery stores was 22·6 (sd 8·1), compared with 6·6 (sd 5·2) in convenience stores ( < 0·0001); and mean price subscale score (possible range -9 to 18; higher score indicates that healthier options were less expensive than the less healthy options) for grocery stores was 2·4 (sd 2·7), compared with 0·7 (sd 1·2) in convenience stores ( = 0·0080). Mean total NEMS-S score (possible range -9 to 54) in grocery stores was 29·8 (sd 10·9) compared with 7·3 (sd 7·1) in convenience stores ( < 0·0001). Both grocery and convenience stores could be strategic points of intervention to improve the nutrition environment in the counties that were surveyed.
营养环境,包括食品店类型,可能会影响饮食选择,进而影响肥胖风险以及冠心病、糖尿病和癌症等相关慢性病的发病风险。本研究的目的是阐明各类乡村食品销售点中健康食品的可得性和可负担性。使用商店营养环境测量调查(NEMS-S)对营养环境的一个子集进行了评估。NEMS-S工具评估了健康食品(如低脂/脱脂牛奶、瘦肉和低脂主餐)与健康程度较低的同类食品(如全脂牛奶、非瘦肉和普通主餐)的可得性和价格。NEMS-S还评估了新鲜水果和蔬菜的质量。对阿拉巴马州九个乡村县的杂货店(24家)和便利店(67家)的健康食品可得性、价格和质量进行了比较。杂货店的平均可得性子量表得分(可能范围为0至30;得分越高表明可得的健康食品数量越多)为22.6(标准差8.1),而便利店为6.6(标准差5.2)(P<0.0001);杂货店的平均价格子量表得分(可能范围为-9至18;得分越高表明健康食品选项比不健康食品选项更便宜)为2.4(标准差2.7),便利店为0.7(标准差1.2)(P=0.0080)。杂货店的平均NEMS-S总得分(可能范围为-9至54)为29.8(标准差10.9),便利店为7.3(标准差7.1)(P<0.0001)。杂货店和便利店都可能是改善所调查各县营养环境的战略干预点。
