To examine the association between the local food environment and the severity of food insecurity among new families using community food security interventions in Montreal.
In this cross-sectional study, we analyzed baseline data from 785 adults aged 18-65 years enrolled in the evaluation of the effects of organizations delivering community food security interventions in Montreal. The dependent variable was household food insecurity, while the independent variable was the local food environment, assessed through: location of the most frequently used grocery store, distance between the participant's residence and the community organization used, mode of transportation, walking time to the most frequently used grocery store, satisfaction with the acceptability and affordability of food available at the most frequently used grocery store, and self-reported difficulties in accessing food. We used polytomous logistic regression to estimate the association between household food insecurity and the local food environment. In all the models, we coded food security status in three categories: food security, moderate food insecurity and severe food insecurity. The last group was used as a reference group.
Our data suggest that compared to households with severe food insecurity, those with moderate food insecurity (OR = 0.43, 95% CI: 0.28-0.62) and those with food security (OR = 0.13, 95% CI: 0.06-0.26) were less likely to report difficulties in accessing food due to food affordability. Food-secure households also had lower odds of reporting difficulties in accessing food due to transportation constraints (OR = 0.18, 95% CI: 0.06-0.55) compared with severe food-insecure households. Living a distance of between 1 and 2 km from the organization used was significantly correlated with moderate food insecurity (OR = 1.80, 95% CI: 1.12-2.88).
The local food environment is associated with severity of household food insecurity among new families using community food security interventions in Montreal. Future studies should study the relationship between the local food environment and food insecurity across all dimensions of food access.
研究蒙特利尔市采用社区粮食安全干预措施的新家庭中,当地食物环境与粮食不安全严重程度之间的关联。
在这项横断面研究中,我们分析了785名年龄在18 - 65岁的成年人的基线数据,这些成年人参与了对蒙特利尔市提供社区粮食安全干预措施的组织的效果评估。因变量是家庭粮食不安全状况,自变量是当地食物环境,通过以下方面进行评估:最常使用的杂货店的位置、参与者住所与所使用的社区组织之间的距离、交通方式、步行到最常使用的杂货店的时间、对最常使用的杂货店中食物的可接受性和可负担性的满意度,以及自我报告的获取食物困难情况。我们使用多分类逻辑回归来估计家庭粮食不安全与当地食物环境之间的关联。在所有模型中,我们将粮食安全状况分为三类进行编码:粮食安全、中度粮食不安全和严重粮食不安全。最后一组作为参照组。
我们的数据表明,与严重粮食不安全的家庭相比,中度粮食不安全的家庭(比值比=0.43,95%置信区间:0.28 - 0.62)和粮食安全的家庭(比值比=0.13,95%置信区间:0.06 - 0.26)因食物可负担性而报告获取食物困难的可能性较小。与严重粮食不安全的家庭相比,粮食安全的家庭因交通限制而报告获取食物困难的几率也较低(比值比=0.18,95%置信区间:0.06 - 0.55)。居住在距离所使用的组织1至2公里处与中度粮食不安全显著相关(比值比=1.80,95%置信区间:1.12 -
