Prospective associations between diet quality, dietary components, and risk of cardiometabolic multimorbidity in older British men

Abstract

Purpose Cardiometabolic multimorbidity (CMM) is a major public health challenge. This study investigated the prospective relationships between diet quality, dietary components, and risk of CMM in older British men. Methods We used data from the British Regional Heart Study of 2873 men aged 60–79 free of myocardial infarction (MI), stroke, and type 2 diabetes (T2D) at baseline. CMM was defined as the coexistence of two or more cardiometabolic diseases, including MI, stroke, and T2D. Sourcing baseline food frequency questionnaire, the Elderly Dietary Index (EDI), which was a diet quality score based on Mediterranean diet and MyPyramid for Older Adults, was generated. Cox proportional hazards regression and multi-state model were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs). Results During a median follow-up of 19.3 years, 891 participants developed first cardiometabolic disease (FCMD), and 109 developed CMM. Cox regression analyses found no significant association between baseline EDI and risk of CMM. However, fish/seafood consumption, a dietary component of the EDI score, was inversely associated with risk of CMM, with HR 0.44 (95% CI 0.26, 0.73) for consuming fish/seafood 1–2 days/week compared to less than 1 day/week after adjustment. Further analyses with multi-state model showed that fish/seafood consumption played a protective role in the transition from FCMD to CMM. Conclusions Our study did not find a significant association of baseline EDI with CMM but showed that consuming more fish/seafood per week was associated with a lower risk of transition from FCMD to CMM in older British men.

Association between Dietary Total Vitamin A, β-carotene, and Retinol Intake and Risk of cardiometabolic multimorbidity: Results from the China Health and Nutrition Survey, 1997–2015

“…It has been reported that CMM not only signi cantly increases the risk of adverse outcomes such as dementia, reduces the quality of life of patients, and results in shorter life expectancy, but also poses a signi cant challenge to the healthcare system [5][6][7][8][9] . In response to this challenge, research on CMM has intensi ed, and the role of nutrients at the level of modi able risk and preventive factors has gained widespread attention [10][11][12][13] .…”
