Exploring the relationship between dietary patterns and health-related quality of life among Iranian adult population: Tehran lipid and glucose study
This study by Niknam et al. (2025) investigated the relationship between various dietary patterns and health-related quality of life (HRQoL) in a large group of Iranian adults. Researchers examined information obtained from 5,711 persons (53% women) via trained interviewers using data from the Tehran Lipid and Glucose Study (TLGS). Dietary intake was measured using a 147-item semi-quantitative Food Frequency Questionnaire (FFQ), while HRQoL was assessed with the Short-Form 12-Item Health Survey (SF-12v2), which includes physical (PCS) and mental (MCS) component scores. Researchers identified two main dietary patterns—”Healthy” and “Western”—through factor analysis. General linear models were used to evaluate the relationship between these dietary patterns and HRQoL. Among men, the median PCS and MCS scores were 51.4 and 52.2, respectively. Among women, these values were 48.9 and 47.7. Both men and women showed higher MCS scores as adherence to the healthy dietary pattern increased. However, only women showed a significant positive trend in PCS scores. There was no discernible correlation between women’s PCS or MCS scores and the Western eating pattern. In contrast, men who followed the Western dietary pattern more closely had lower MCS scores. In summary, healthy eating patterns appear to improve both physical and mental aspects of quality of life in women, while in men, they primarily benefit mental well-being. Conversely, a Western dietary pattern may negatively affect men’s mental quality of life.
