A loss of the ability to buy and prepare meals, especially in people aged 65 and over, leads to a deterioration in their optimal level of nutrition. The Index of Autonomy in Food Acquisition (IAFA) was used to identify contributing factors. This is a composite indicator for shopping and meal preparation that can be used to assess the degree of autonomous capacity observed in a specific group. Data from the European Health Survey in Spain (7167 respondents aged 65 and over) show that capacity decreased with age and that women were less affected than men, with very little difference found in levels of autonomous capacity by territory. However, in relation to different income levels, after standardizing for age and sex, no evidence was found for differences in the ability to access and prepare meals in groups that were separated by income level. This result shows the importance of standardizing when analysing food acquisition autonomy in groups of people aged 65 years and over.
无法购买和准备食物的能力丧失，尤其是在 65 岁及以上的人群中，会导致其最佳营养水平下降。使用食品获取自主性指数（IAFA）来确定促成因素。这是一个用于评估特定群体中观察到的自主能力程度的购物和膳食准备综合指标。来自西班牙的欧洲健康调查的数据（7167 名年龄在 65 岁及以上的受访者）显示，随着年龄的增长，这种能力会下降，而女性受影响的程度低于男性，不同地区之间的自主能力水平差异很小。然而，在不同的收入水平方面，在按年龄和性别标准化后，没有发现按收入水平划分的群体在获取和准备食物方面的能力存在差异的证据。这一结果表明，在分析 65 岁及以上人群的食品获取自主性时，标准化的重要性。
