The current study aims to investigate the association between dietary patterns and health-related quality of life (HRQoL) in a large Iranian adult population.
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.
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.
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.
本研究旨在调查伊朗成年人群中饮食模式与健康相关生活质量（HRQoL）之间的关联。
本横断面研究使用德黑兰血脂与血糖研究（TLGS）数据。分析了由经过培训的访谈员收集的5711名成年人（53.0%为女性）的数据。分别使用147项半定量食物频率问卷（FFQ）和简版12项健康调查第2版（SF-12v2）评估饮食摄入量和HRQoL。使用适当的评分算法计算HRQoL的身体成分总结（PCS）和心理成分总结（MCS）得分。通过因子分析确定饮食模式。使用一般线性模型评估饮食模式与HRQoL得分之间的关联。
确定了两种饮食模式，分别标记为健康型和西方型。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）。在健康饮食模式三分位数分组中，男性和女性的MCS得分均呈现显著上升趋势。对于PCS得分，仅在女性中观察到显著上升趋势。西方饮食模式与女性的PCS或MCS均无显著关联。然而，在男性中，西方饮食模式三分位数分组中MCS得分呈现显著下降趋势。
本研究表明健康饮食模式对女性的HRQoL有更有益的影响。另一方面，在男性中，健康饮食模式与HRQoL的心理维度呈正相关，而西方饮食模式与HRQoL的心理维度呈负相关。
