To explore the relationship between type of grocery store used (chain vs. independent), transportation access, food insecurity, and fruit and vegetable intake in Detroit, Michigan, USA, during the COVID-19 pandemic.
A cross-sectional online survey was conducted from December 2021 to May 2022.
Detroit, Michigan.
656 Detroit residents aged 18 and older.
Bivariate analyses showed that chain grocery store shoppers reported significantly greater fruit and vegetable intake (2.42 vs. 2.14 times/day for independent grocery store shoppers, < 0.001) and lower rates of food insecurity compared to independent store shoppers (45.9% vs. 65.3% for independent grocery store shoppers, < 0.001). Fewer independent store shoppers used their own vehicle (52.9% vs. 76.2% for chain store shoppers, < 0.001). After adjusting for socioeconomic and demographic variables transportation access was strongly associated with increased odds of shopping at chain stores (OR = 1.89, 95% CI [1.21,2.95], = 0.005) but food insecurity was no longer associated with grocery store type. Shopping at chain grocery stores was associated with higher fruit and vegetable intake after adjusting for covariates (1.18 times more per day, = 0.042). Qualitative responses highlighted systemic barriers, including poor food quality, high costs, and limited transportation options, exacerbating food access inequities.
These disparities underscore the need for targeted interventions to improve transportation options and support food security in vulnerable populations, particularly in urban areas like Detroit. Addressing these structural challenges is essential for reducing food insecurity and promoting equitable access to nutritious foods.
探讨在美国密歇根州底特律市新冠疫情期间，所使用的杂货店类型（连锁 vs. 独立经营）、交通便利性、粮食不安全状况与水果和蔬菜摄入量之间的关系。
于2021年12月至2022年5月进行了一项横断面在线调查。
密歇根州底特律市。
656名年龄在18岁及以上的底特律居民。
双变量分析显示，与独立杂货店购物者相比，连锁杂货店购物者报告的水果和蔬菜摄入量显著更高（独立杂货店购物者为每天2.14次，连锁杂货店购物者为每天2.42次，<0.001），且粮食不安全率更低（独立杂货店购物者为65.3%，连锁杂货店购物者为45.9%，<0.001）。较少独立杂货店购物者使用自己的车辆（连锁商店购物者为76.2%，独立商店购物者为52.9%，<0.001）。在调整社会经济和人口统计学变量后，交通便利性与在连锁商店购物的几率增加密切相关（OR = 1.89，95%CI[1.21,2.95]，= 0.005），但粮食不安全状况与杂货店类型不再相关。在调整协变量后，在连锁杂货店购物与更高的水果和蔬菜摄入量相关（每天多1.18倍，= 0.042）。定性回答突出了系统性障碍，包括食品质量差、成本高和交通选择有限，加剧了食品获取的不平等。
这些差异凸显了有针对性干预措施的必要性，以改善交通选择并支持弱势群体的粮食安全，特别是在底特律这样的城市地区。应对这些结构性挑战对于减少粮食不安全和促进公平获取营养食品至关重要。
