To characterize 12-month trends in the use of food donations and other food-related community-based social assistance programs (CB-SAPs) during the first year following the enrollment of new food bank (FB) users in Quebec, Canada. A cohort of 1,001 newly registered FB-users in Quebec from the Pathways Study were followed-up during 12-month following baseline assessment. Outcomes were monthly use of food donations and other food-related CB-SAPs. Main predictors were alternative food source utilization (AFSU) profiles: 1) exclusive-FB-users; 2) FB+fruit/vegetable-market-users; and 3) Multiple/diverse-AFS-users. Covariates included sociodemographic characteristics, health status, and major life events. We fit Bayesian hierarchical mixed-effect models, accounting for spatial clustering, temporal correlation, and censoring. We observed an overall downward trend of food donation use among study completers ( = 745). Each AFSU profile had a distinctive monthly trend of food donation use, but probabilities of use across the three profiles overlapped, between 44% and 55%. The use of other food-related CB-SAPs was low and not correlated with AFSU profiles. FB-users use food donations in different ways over time according to specific contextual AFSU profiles.
为了描述加拿大魁北克省新加入食品银行（FB）的用户在注册后的第一年中，食品捐赠和其他与食品相关的社区基础援助计划（CB-SAP）的使用在 12 个月内的变化趋势。对 Pathways 研究中的 1001 名新注册的 FB 用户进行了为期 12 个月的随访，随访时间为基线评估后。结果是每月使用食品捐赠和其他与食品相关的 CB-SAP。主要预测因素是替代食品来源利用（AFSU）的模式：1）只使用 FB 的用户；2）使用 FB+果蔬市场的用户；3）多种/多样化的 AFS 用户。协变量包括社会人口统计学特征、健康状况和重大生活事件。我们拟合了贝叶斯层次混合效应模型，考虑了空间聚类、时间相关性和删失。我们观察到研究完成者中食品捐赠使用的总体下降趋势（n=745）。每种 AFSU 模式都有独特的每月食品捐赠使用趋势，但三种模式之间的使用概率重叠，在 44%到 55%之间。其他与食品相关的 CB-SAP 的使用量较低，与 AFSU 模式无关。FB 用户根据特定的背景下的 AFSU 模式，以不同的方式在不同时间使用食品捐赠。
