Eleven percent of households in the United States experience food insecurity, which is a lack of access to adequate, desirable food for a healthy lifestyle. Although food insecurity is associated with increased risk of obesity and nonadherence to dietary management of chronic diseases such as diabetes, the correlates of food insecurity have not yet been studied in a bariatric surgery population.
To replicate, in a bariatric sample, previous findings that food insecurity is related to eating pathology and to test the hypothesis that this relationship is mediated by depressive symptoms.
University hospital, United States.
Two hundred forty bariatric surgery candidates responded to self-report measures of food insecurity and mood, night-eating, and binge-eating symptoms. The sample was 74% female and 71% white, with a mean age of 41.09 (11.84) years. Based on responses to the United States Department of Agriculture Adult Food Security Survey Model, 15.8% were categorized as food insecure and 25.8% as marginally food secure. Multiple regression models with bootstrapping for confidence interval estimates were used to explore mediation hypotheses.
Food insecurity was positively associated with symptoms of night eating and binge eating, and these relationships were cross-sectionally mediated by depressive symptoms.
Food insecure bariatric candidates may be at increased risk of poorer postoperative outcomes because of lack of access to needed food and the detrimental mental health impact of this lack of access.
美国有 11%的家庭存在食物不安全问题，这意味着他们无法获得健康生活所需的充足、理想的食物。尽管食物不安全与肥胖风险增加以及慢性疾病（如糖尿病）饮食管理不依从有关，但在减重手术人群中，尚未研究食物不安全的相关因素。
在减重手术患者中复制先前发现的食物不安全与饮食病理之间的关系，并检验抑郁症状在这一关系中起中介作用的假设。
美国的一家大学医院。
240 名减重手术候选者回答了关于食物不安全和情绪、夜间进食和暴食症状的自我报告测量。样本中 74%为女性，71%为白人，平均年龄为 41.09（11.84）岁。根据美国农业部成人食物安全调查模型的回答，15.8%的人被归类为食物不安全，25.8%的人被归类为边缘性食物安全。使用具有置信区间估计 bootstrap 的多元回归模型来探索中介假设。
食物不安全与夜间进食和暴食症状呈正相关，这些关系在横截面上受到抑郁症状的中介。
由于无法获得所需的食物，以及这种无法获得食物对心理健康的不利影响，食物不安全的减重手术候选者可能面临术后结果恶化的风险。
