To determine whether residence in a US Department of Agriculture-designated food desert is associated with perceived access to healthy foods, grocery shopping behaviours, diet and BMI among a national sample of primary food shoppers.
Data for the present study came from a self-administered cross-sectional survey administered in 2015. Residential addresses of respondents were geocoded to determine whether their census tract of residence was a designated food desert or not. Inverse probability of treatment-weighted regression was used to assess whether residence in a food desert was associated with dependent variables of interest.
USA.
Of 4942 adult survey respondents, residential addresses of 75·0 % (n 3705) primary food shoppers were included in the analysis.
Residence in a food desert (11·1 %, n 411) was not significantly associated with perceived access to healthy foods, most grocery shopping behaviours or dietary behaviour, but was significantly associated with primarily shopping at a superstore or supercentre v. a large grocery store (OR = 1·32; 95 % CI 1·02, 1·71; P = 0·03) and higher BMI (b = 1·14; 95 % CI 0·36, 1·93; P = 0·004).
Results suggest that food desert residents shop at different food stores and have higher BMI than non-food desert residents.
在美国农业部指定的食品荒漠居住是否与健康食品的感知获取、杂货店购物行为、饮食和 BMI 有关，本研究旨在确定这一问题。
本研究的数据来自于 2015 年进行的一项自我管理的横断面调查。受访者的居住地址进行了地理编码，以确定他们居住的普查区是否为指定的食品荒漠。使用逆概率治疗加权回归来评估居住在食品荒漠是否与感兴趣的因变量相关。
美国。
在 4942 名成年调查受访者中，有 75.0%（n=3705）的主要食品购物者的居住地址被纳入分析。
居住在食品荒漠（11.1%，n=411）与健康食品的感知获取、大多数杂货店购物行为或饮食行为没有显著关联，但与主要在超市或超级中心购物而不是在大型杂货店购物显著相关（OR=1.32；95%CI 1.02，1.71；P=0.03），并且 BMI 更高（b=1.14；95%CI 0.36，1.93；P=0.004）。
结果表明，食品荒漠居民在不同的食品店购物，并且 BMI 高于非食品荒漠居民。
