BACKGROUND/OBJECTIVES: Food-insecure individuals are at risk for poor health outcomes, including substandard sleep health. A possible association of food insecurity with sleep regularity has not been explored, and factors contributing to the relationship between food insecurity and sleep are not well understood. This cross-sectional study explored the relationship between food insecurity and sleep regularity and identified specific nutrients that mediated the association.
This study used dietary intake, interview, physical examination, actigraphy, and laboratory data from NHANES 2011-2014 to assess the possible correlation between food insecurity and sleep in a sample of U.S. adults ( = 6730). Mediation analysis was conducted to determine specific serum biomarkers and intake of nutrients that indirectly contributed to the relationship.
Food insecurity was negatively correlated with sleep regularity. Dietary intake of fiber; vitamins A, B1, B2, C, E, and K; β-carotene; zinc; copper; and potassium and serum concentrations of palmitoleic acid had significant indirect effects on this association. The low/marginal food security group under-consumed vitamin K, and the very low food security group under-consumed vitamin K and zinc. Among food-insecure, income-eligible adults, those who received benefits from food assistance programs consumed significantly less fiber and β-carotene and exhibited significantly higher serum concentrations of palmitoleic acid than non-participants.
Food insecurity predicted sleep regularity, and this relationship was mediated by dietary intake and serum concentrations of specific nutrients, underscoring the role of nutrition security when evaluating potential health impacts for adults experiencing food insecurity.
背景/目的：粮食不安全的个体面临健康状况不佳的风险，包括睡眠健康不达标准。粮食不安全与睡眠规律之间的可能关联尚未得到探究，且导致粮食不安全与睡眠之间关系的因素也未被充分理解。这项横断面研究探讨了粮食不安全与睡眠规律之间的关系，并确定了介导这种关联的特定营养素。
本研究使用了2011 - 2014年美国国家健康与营养检查调查（NHANES）中的饮食摄入量、访谈、体格检查、活动记录仪和实验室数据，以评估美国成年人样本（n = 6730）中粮食不安全与睡眠之间的可能相关性。进行中介分析以确定间接促成这种关系的特定血清生物标志物和营养素摄入量。
粮食不安全与睡眠规律呈负相关。膳食纤维、维生素A、B1、B2、C、E和K、β - 胡萝卜素、锌、铜、钾的饮食摄入量以及棕榈油酸的血清浓度对这种关联有显著的间接影响。低/边缘粮食安全组维生素K摄入不足，极低粮食安全组维生素K和锌摄入不足。在符合收入条件的粮食不安全成年人中，那些从食品援助计划中受益的人膳食纤维和β - 胡萝卜素的摄入量显著低于非参与者，且棕榈油酸的血清浓度显著更高。
粮食不安全可预测睡眠规律，这种关系由特定营养素的饮食摄入量和血清浓度介导，这凸显了在评估粮食不安全成年人潜在健康影响时营养安全的作用。
