To examine the agreement in nutrient intake and alternative healthy eating indices (AHEI) between a self-administered Food Frequency Questionnaire (FFQ) and 24-hour recall (24HR) measurements of diet by gender, among older adults.
This is a cross-sectional observational study of 105 men and 99 women aged 65 and older living in urban and rural neighborhoods in Worcester County, Massachusetts, USA. Participants were queried on diet using both FFQ and 24HR. The healthy eating classification was compared between the two instruments by gender.
For men, the mean ± SD of AHEI total score was 48.2 ± 12.3 based on FFQ versus 34.7 ± 10.2 based on 24HR. For women, the mean ± SD was 47.9 ± 10.1 based on FFQ versus 36.1 ± 10.0 based on 24HR. Using 32 as the cutoff (40% of maximum AHEI score), 9% of men and 7% of women were classified as eating unhealthy based on the FFQ, versus 47% of men and 38% of women based on 24HR. Compared to women, men had larger 24HR to FFQ discrepancies in the nuts and vegetable protein subscore and white/red meat ratio, and smaller discrepancy in alcohol beverages subscore.
Agreements between FFQ and 24HR-based measures of diet quality were roughly comparable between men and women, though slightly better for women than men. Compared to 24HR, the FFQ tended to underestimate the proportions of older men and women classified as eating unhealthy and misclassified more men than women. Such limitations should be considered when the FFQ is used to study healthy eating in older age.
在老年人中，按性别研究自行填写的食物频率问卷（FFQ）与24小时膳食回顾法（24HR）在营养摄入量及替代健康饮食指数（AHEI）方面的一致性。
这是一项横断面观察性研究，研究对象为美国马萨诸塞州伍斯特县城乡社区的105名65岁及以上男性和99名65岁及以上女性。使用FFQ和24HR对参与者的饮食情况进行询问。按性别比较两种工具在健康饮食分类方面的情况。
对于男性，基于FFQ的AHEI总分均值±标准差为48.2±12.3，而基于24HR的为34.7±10.2。对于女性，基于FFQ的均值±标准差为47.9±10.1，基于24HR的为36.1±10.0。以32分为临界值（AHEI最高分的40%），基于FFQ，9%的男性和7%的女性被归类为饮食不健康，而基于24HR，这一比例分别为47%的男性和38%的女性。与女性相比，男性在坚果和植物蛋白子得分以及白肉/红肉比例方面，24HR与FFQ的差异更大，而在酒精饮料子得分方面差异较小。
FFQ与基于24HR的饮食质量测量方法之间的一致性在男性和女性中大致相当，不过女性略好于男性。与24HR相比，FFQ往往低估了被归类为饮食不健康的老年男性和女性的比例，且将男性误分类的情况多于女性。在使用FFQ研究老年人健康饮食时，应考虑到这些局限性。
