Abstract

Background: The current study aims to investigate the association between dietary patterns and health-related quality of life (HRQoL) in a large Iranian adult population.

Methods: This cross-sectional study was conducted using the Tehran Lipid and Glucose Study (TLGS) data. Data from 5711 adults (53.0% female) collected by trained interviewers were analyzed. For assessments of dietary intakes and HRQoL, the 147-item semi-quantitative Food Frequency Questionnaire (FFQ) and Short-Form 12-Item Health Survey version 2 (SF-12v2) were used, respectively. The physical component summary (PCS) and mental component summary (MCS) scores of HRQoL were calculated using the appropriate scoring algorithms. Dietary patterns were identified using factor analysis. General linear models were used to assess the association between dietary patterns and HRQoL scores.

Results: Two dietary patterns, labeled as healthy and western, were identified. In men, the median (interquartile range (IQR)) of PCS and MCS were 51.4 (47.2-55.0) and 52.2 (44.2-58.2), respectively. For women, the median (IQR) of PCS and MCS were 48.9 (42.6-53.7) and 47.7 (39.6-55.2), respectively. Significant increasing trends in MCS scores were observed in both men and women across tertiles of healthy dietary pattern. For PCS scores, a significant increasing trend was noted only in women. The Western dietary pattern was not significantly associated with either PCS or MCS in women. However, in men, a significant decreasing trend in MCS scores was observed across tertiles of the Western dietary pattern.

Conclusions: The present study suggests a more beneficial effect of healthy dietary pattern on women's HRQoL. On the other hand, in men, the healthy dietary pattern is positively associated with the mental dimension of HRQoL, whereas the Western dietary pattern is negatively linked to the mental dimension of HRQoL.

探索伊朗成年人饮食模式与健康相关生活质量之间的关系：德黑兰脂质和葡萄糖研究

背景：本研究旨在调查大量伊朗成年人饮食模式与健康相关生活质量（HRQoL）之间的关系。方法：采用德黑兰脂质和葡萄糖研究（TLGS）数据进行横断面研究。由训练有素的采访者收集5711名成年人（53.0%为女性）的数据进行分析。对于膳食摄入量和HRQoL的评估，分别使用了147项半定量食物频率问卷（FFQ）和简短的12项健康调查版本2 （SF-12v2）。采用相应的评分算法计算HRQoL的物理成分总结（PCS）和心理成分总结（MCS）得分。采用因子分析确定饮食模式。一般线性模型用于评估饮食模式与HRQoL评分之间的关系。结果：确定了健康饮食和西式饮食两种饮食模式。在男性中，PCS和MCS的中位数（四分位间距（IQR））分别为51.4（47.2-55.0）和52.2（44.2-58.2）。对于女性，PCS和MCS的中位数（IQR）分别为48.9（42.6-53.7）和47.7（39.6-55.2）。在健康饮食模式的男性和女性中，MCS评分都有显著增加的趋势。对于PCS分数，只有女性有显著的上升趋势。西方饮食模式与女性的PCS或MCS没有显著关联。然而，在男性中，在西方饮食模式中观察到MCS评分显著下降的趋势。结论：本研究提示健康饮食模式对女性HRQoL有更有利的影响。另一方面，在男性中，健康饮食模式与HRQoL的心理维度正相关，而西方饮食模式与HRQoL的心理维度负相关。
