This study investigated the early impact of a community-based food intervention, the Good Food Junction (GFJ), a full-service grocery store (September 2012 - January 2016) in a former food desert in Saskatoon, Canada. The hypothesis tested was that frequent shopping at the GFJ improved food security and selected health-related outcomes among shoppers, and the impact was moderated by socioeconomic factors. Longitudinal data were collected from 156 GFJ shoppers, on three occasions: 12-, 18-, and 24-months post-opening. Participants were grouped into three categories based on the frequency of shopping at the GFJ: low, moderate, and high. A generalized estimating equations approach was used for model building; moderating effects were tested. Participants were predominantly female, Indigenous, low-income, and had high school or some post-secondary education. The GFJ use was associated with household food security (OR for high and moderate frequency shoppers reporting less than a high school education were 1.81 and 1.06, respectively), and mental health (OR for high and moderate frequency shoppers reporting high income were 2.82 and 0.87, respectively) exhibiting a dose-response relationship, and indicated that these outcomes were significantly moderated by participants' socioeconomic factors. Shopping at the GFJ had a positive effect on food security and mental health, but to varying levels for those with low incomes, with less than high school or high school or better levels of education.
本研究调查了一个社区食品干预措施——Good Food Junction（GFJ）的早期影响，该措施是加拿大萨斯卡通一个前食品沙漠中的一家全方位服务杂货店（2012 年 9 月至 2016 年 1 月）。测试的假设是，频繁光顾 GFJ 可以改善购物者的粮食安全和选定的与健康相关的结果，并且这种影响受到社会经济因素的调节。从 156 名 GFJ 购物者那里收集了纵向数据，在开业后 12、18 和 24 个月进行了三次调查。参与者根据在 GFJ 的购物频率分为三组：低、中、高。使用广义估计方程方法进行模型构建；测试了调节作用。参与者主要是女性、原住民、低收入，并且具有高中或一些专上教育水平。GFJ 的使用与家庭粮食安全有关（报告教育程度低于高中的高频率和中频率购物者的优势比分别为 1.81 和 1.06），以及心理健康（报告高收入的高频率和中频率购物者的优势比分别为 2.82 和 0.87），表现出剂量反应关系，表明这些结果受到参与者社会经济因素的显著调节。在 GFJ 购物对粮食安全和心理健康有积极影响，但对于收入较低、教育程度低于高中或高中或以上的人来说，影响程度不同。
