粮食安全（获得安全、营养和负担得起的食物）与压力或痛苦感有着内在联系，并与社会经济因素密切相关。然而，不考虑混杂的社会经济因素，粮食不安全对心理健康的影响尚不清楚。我们调查了新西兰食物不安全与心理困扰的关系，控制了社会经济因素。其次，我们检查了男性和女性的关联。我们使用的数据来自家庭、收入和就业调查（SoFIE） （N = 18,955）。如果受访者在过去12个月内：使用特殊食品补助金/银行，不得不购买更便宜的食品来支付其他费用，或者经常没有新鲜水果和蔬菜，则被归类为粮食不安全。采用低（10-15）和中高（16+）的Kessler-10量表进行心理困扰的测量。逻辑回归分析被用来调查食品不安全与心理困扰的关系，使用分阶段建模方法。相互作用模型包括粮食安全与性别之间的相互作用，以及性别与所有其他协变量之间的相互作用（p值< 0.1显著）。模型被重复，按性别分层。发现食品不安全和心理困扰之间有很强的关系（粗优势比OR 3.4）。虽然显著降低，但在调整了混杂的人口统计学和社会经济变量（调整OR 1.8）后，相关性仍然存在。在分层模型中，食物不安全的女性发生心理困扰的几率（完全调整OR 2.0）略高于男性（完全调整OR 1.5）。因此，在男性和女性中都发现了食物不安全与心理困扰之间的独立关联，而在女性中这一关联略高一些。然而，我们不能排除残余混淆作为独立关联和任何明显的性别相互作用的解释。(C) 2011 Elsevier Ltd.版权所有。
Food security (access to safe, nutritious, affordable food) is intrinsically linked to feelings of stress or distress and it is strongly associated with socioeconomic factors. However, the impact of food insecurity on mental health, independent of confounding socioeconomic factors, is not clear. We investigated the association of food insecurity with psychological distress in New Zealand, controlling for socioeconomic factors. Secondarily, we examined the association in males and females. We used data from the Survey of Families, Income and Employment (SoFIE) (N = 18,955). Respondents were classified as food insecure if, in the last 12 months, they: used special food grants/banks, had to buy cheaper food to pay for other things, or went without fresh fruit and vegetables often. Psychological distress was measured using the Kessler-10 scale dichotomised at low (10-15) and moderate to high (16+). Logistic regression analyses were used to investigate the association of food insecurity with psychological distress using a staged modelling approach. Interaction models included an interaction between food security and gender, as well as interactions between gender and all other covariates (significant at p-value < 0.1). Models were repeated, stratified by gender.A strong relationship between food insecurity and psychological distress was found (crude odds ratio OR 3.4). Whilst substantially reduced, the association remained after adjusting for confounding demographic and socioeconomic variables (adjusted OR 1.8). In stratified models, food insecure females had slightly higher odds for psychological distress (fully adjusted OR 2.0) than males (fully adjusted OR 1.5). As such, an independent association of food insecurity with psychological distress was found in both males and females slightly more so in females. However, we cannot rule out residual confounding as an explanation for the independent association and any apparent gender interaction. (C) 2011 Elsevier Ltd. All rights reserved.
