This cross-sectional study among low-income mother-child dyads examined the relationship between food security status and hair cortisol concentration (HCC), and how mother and child food security status was interactively related to mothers' perceived distress and coping. Data from 32 dyads were analyzed. Approximately 46.9% had household food insecurity, 37.5% children had food insecurity, and 34.4% mothers had food insecurity. Children with food insecurity had significantly higher HCC than those with food security. A significant interaction effect occurred between child food security status and race on children's HCC, with White children's HCC being more likely to be influenced by food security status. Mother food security and child food security status together explained about 6% of the variance in mothers' HCC, 27% in perceived distress, and 18% in perceived coping. These findings indicate that assisting low-income families with food insecurity to get enough food can benefit both children's and mothers' mental health.
这项针对低收入母婴二元组的横断面研究，考察了粮食安全状况与头发皮质醇浓度（HCC）之间的关系，以及母婴粮食安全状况如何与母亲的感知痛苦和应对方式产生交互关联。对来自32个二元组的数据进行了分析。约46.9%的家庭存在粮食不安全问题，37.5%的儿童存在粮食不安全问题，34.4%的母亲存在粮食不安全问题。粮食不安全的儿童的HCC显著高于粮食安全的儿童。儿童粮食安全状况与种族之间对儿童的HCC产生了显著的交互作用，白人儿童的HCC更有可能受到粮食安全状况的影响。母亲的粮食安全和儿童的粮食安全状况共同解释了母亲HCC变异的约6%、感知痛苦变异的27%以及感知应对变异的18%。这些研究结果表明，帮助存在粮食不安全问题的低收入家庭获得足够的食物，对儿童和母亲的心理健康均有益处。
