Food security remains a global public health priority but there may be bias in the prevalence of household food insecurity, depending upon who answers the questions. Using a cross-section from the Household, Income and Labour Dynamics in Australia (HILDA) Survey, we analysed components of food insecurity reported separately by both partners in 718 households, allowing examination of discrepancies among couples. We modelled discrepancy in reports of food insecurity on 8 items using binary logit models for each question and a binomial regression for the number of questions on which there was discrepancy. Among couples who differed on an item, (conditional) discrepancy rates ranged from 71.75% to 85.86%. Females were more likely than males to report food insecurity on most items. Key characteristics associated with discrepancy were female's and male's age, female's education, being born in Australia, renting and male's employment. Male's age and birthplace were associated with discrepancy on more items while male's higher education and being a homeowner were associated with discrepancy on fewer items. Among couples who differed in responses, females were more likely to report food insecurity if they were older or had a disability, if their male partner was younger or had no disability, or if either person had more education than high school. The prevalence of food insecurity among couple households may be underestimated by 7.4 percentage points due to discrepancies in reporting. Discrepancies can reduce the accuracy of measures of food insecurity, impeding the targeting of responses, and lead to a less efficient allocation of resources to combat food insecurity.

粮食不安全：澳大利亚夫妇家庭内部的差异

粮食安全仍然是全球公共卫生的优先事项，但家庭粮食不安全的普遍程度可能存在偏差，具体取决于回答问题的人。我们利用澳大利亚家庭、收入和劳动力动态 (HILDA) 调查的横截面，分析了 718 个家庭中伴侣分别报告的粮食不安全的组成部分，从而检查了夫妻之间的差异。我们对每个问题使用二元 Logit 模型，并对存在差异的问题数量使用二项式回归，对 8 个项目的粮食不安全报告中的差异进行建模。在某件事上存在分歧的夫妻中，（有条件的）差异率在 71.75% 到 85.86% 之间。女性比男性更有可能报告大多数物品的粮食不安全问题。与差异相关的关键特征是女性和男性的年龄、女性的教育程度、在澳大利亚出生、租房和男性的就业情况。男性的年龄和出生地与更多项目的差异相关，而男性的高等教育和是否是房主与较少项目的差异相关。在反应不同的夫妇中，如果女性年龄较大或有残疾，如果男性伴侣较年轻或没有残疾，或者任何一方的教育程度高于高中，则女性更有可能报告粮食不安全。由于报告差异，夫妻家庭粮食不安全的发生率可能被低估了 7.4 个百分点。差异可能会降低粮食不安全措施的准确性，阻碍应对措施的针对性，并导致应对粮食不安全的资源配置效率较低。
