A major barrier to a healthy diet may be the higher price of healthy foods compared to low-quality foods.
This study aimed to assess the association between the monetary cost of food and diet quality in Spanish older adults at high risk of cardiovascular disease.
Cross-sectional analysis was carried out in Spanish older adults ( = 6,838; 48.6% female). A validated food frequency questionnaire was used to assess dietary intake. Metabolic syndrome severity, adherence to the Mediterranean diet (MedDiet), adherence to a provegetarian dietary pattern, and dietary inflammatory index were assessed. The economic cost of the foods was obtained from the Spanish Ministry of Agriculture Fisheries and Food database (2015-2017, the period of time when the participants were recruited). The total cost of diet adjusted per 1,000 kcal was computed.
The healthier dietary pattern was associated with a higher cost of the diet. Higher adherence to the MedDiet, anti-inflammatory diet, and the healthy version of the provegetarian dietary pattern were related to higher costs of the diet.
Higher diet quality was associated with a higher dietary cost of the diet per 1,000 kcal/day. Food prices can be an important component of interventions and policies aimed at improving people's diets and preventing diet-related chronic diseases.
The trial was registered in 2014 at the International Standard Randomized Controlled Trial (ISRCT; http://www.isrctn.com/ISRCTN89898870) with the number 89898870.
健康饮食的一个主要障碍可能是健康食品的价格相对较高，而低质量食品的价格则较低。
本研究旨在评估西班牙心血管疾病高危老年人群食物货币成本与饮食质量之间的关系。
对西班牙老年人群（n=6838；女性占 48.6%）进行了横断面分析。使用经过验证的食物频率问卷评估饮食摄入情况。评估代谢综合征严重程度、地中海饮食（MedDiet）依从性、素食饮食模式的依从性和饮食炎症指数。从西班牙农业、渔业和食品部数据库（参与者招募期间的 2015-2017 年）获得食物的经济成本。计算每 1000 千卡饮食调整后的总费用。
更健康的饮食模式与更高的饮食成本相关。更高的 MedDiet、抗炎饮食和素食饮食模式的健康版本的依从性与更高的饮食成本相关。
更高的饮食质量与每 1000 千卡/天的饮食费用更高相关。食品价格可能是改善人们饮食和预防与饮食相关的慢性疾病的干预措施和政策的一个重要组成部分。
该试验于 2014 年在国际标准随机对照试验（ISRCT；http://www.isrctn.com/ISRCTN89898870）中注册，编号为 89898870。
