家庭粮食不安全限制了食物选择，但与此问题相关的饮食妥协是否会增加营养不足的风险尚不清楚。本研究的目的是考察家庭粮食安全状况与成人和儿童膳食摄入量之间的关系，并根据家庭粮食安全状况来估计成人和儿童营养不足的患病率。我们分析了 2004 年加拿大社区健康调查（周期 2.2）中 1 - 70 岁人群的 24 小时召回和家庭食品安全数据。使用回归分析评估成人和儿童的营养和食物摄入量与家庭粮食安全状况之间的关系。使用概率评估方法计算了按粮食安全状况和年龄/性别组划分的营养摄入不足发生率的估计值。在粮食不安全家庭中，青少年和成年人的饮食摄入量较差，在考虑多变量分析中的潜在混杂因素后，粮食安全状况的许多差异仍然存在。粮食不安全家庭的青少年和成年人营养不足的估计患病率明显较高，其中蛋白质、维生素 A、硫胺素、核黄素、维生素 B-6、叶酸、维生素 B-12、镁、磷和锌方面的差异最为明显。在儿童中，家庭粮食安全状况的膳食摄入量差异不大，也几乎没有迹象表明营养不足。这项研究表明，对于成年人以及某种程度上的青少年来说，粮食不安全与营养摄入不足有关。这些发现强调需要采取协调一致的公共政策应对措施，以改善家庭粮食不安全状况。
Household food insecurity constrains food selection, but whether the dietary compromises associated with this problem heighten the risk of nutrient inadequacies is unclear. The objectives of this study were to examine the relationship between household food security status and adults' and children's dietary intakes and to estimate the prevalence of nutrient inadequacies among adults and children, differentiating by household food security status. We analyzed 24-h recall and household food security data for persons aged 1 - 70 y from the 2004 Canadian Community Health Survey (cycle 2.2). The relationship between adults' and children's nutrient and food intakes and household food security status was assessed using regression analysis. Estimates of the prevalence of inadequate nutrient intakes by food security status and age/sex group were calculated using probability assessment methods. Poorer dietary intakes were observed among adolescents and adults in food-insecure households and many of the differences by food security status persisted after accounting for potential confounders in multivariate analyses. Higher estimated prevalences of nutrient inadequacy were apparent among adolescents and adults in food-insecure households, with the differences most marked for protein, vitamin A, thiamin, riboflavin, vitamin B-6, folate, vitamin B-12, magnesium, phosphorus, and zinc. Among children, few differences in dietary intakes by household food security status were apparent and there was little indication of nutrient inadequacy. This study indicates that for adults and, to some degree, adolescents, food insecurity is associated with inadequate nutrient intakes. These findings highlight the need for concerted public policy responses to ameliorate household food insecurity.
