Diet Quality Scores and Prediction of All-Cause, Cardiovascular and Cancer Mortality in a Pan-European Cohort Study.

ABSTRACT: Scores of overall diet quality have received increasing attention in relation to disease aetiology; however, their value in risk prediction has been little examined. The objective was to assess and compare the association and predictive performance of 10 diet quality scores on 10-year risk of all-cause, CVD and cancer mortality in 451,256 healthy participants to the European Prospective Investigation into Cancer and Nutrition, followed-up for a median of 12.8y. All dietary scores studied showed significant inverse associations with all outcomes. The range of HRs (95% CI) in the top vs. lowest quartile of dietary scores in a composite model including non-invasive factors (age, sex, smoking, body mass index, education, physical activity and study centre) was 0.75 (0.72-0.79) to 0.88 (0.84-0.92) for all-cause, 0.76 (0.69-0.83) to 0.84 (0.76-0.92) for CVD and 0.78 (0.73-0.83) to 0.91 (0.85-0.97) for cancer mortality. Models with dietary scores alone showed low discrimination, but composite models also including age, sex and other non-invasive factors showed good discrimination and calibration, which varied little between different diet scores examined. Mean C-statistic of full models was 0.73, 0.80 and 0.71 for all-cause, CVD and cancer mortality. Dietary scores have poor predictive performance for 10-year mortality risk when used in isolation but display good predictive ability in combination with other non-invasive common risk factors.

Project description:Increased attention in dietary research and guidance has been focused on dietary patterns, rather than on single nutrients or food groups, because dietary components are consumed in combination and correlated with one another. However, the collective body of research on the topic has been hampered by the lack of consistency in methods used. We examined the relationships between 4 indices--the Healthy Eating Index-2010 (HEI-2010), the Alternative Healthy Eating Index-2010 (AHEI-2010), the alternate Mediterranean Diet (aMED), and Dietary Approaches to Stop Hypertension (DASH)--and all-cause, cardiovascular disease (CVD), and cancer mortality in the NIH-AARP Diet and Health Study (n = 492,823). Data from a 124-item food-frequency questionnaire were used to calculate scores; adjusted HRs and 95% CIs were estimated. We documented 86,419 deaths, including 23,502 CVD- and 29,415 cancer-specific deaths, during 15 y of follow-up. Higher index scores were associated with a 12-28% decreased risk of all-cause, CVD, and cancer mortality. Specifically, comparing the highest with the lowest quintile scores, adjusted HRs for all-cause mortality for men were as follows: HEI-2010 HR: 0.78 (95% CI: 0.76, 0.80), AHEI-2010 HR: 0.76 (95% CI: 0.74, 0.78), aMED HR: 0.77 (95% CI: 0.75, 0.79), and DASH HR: 0.83 (95% CI: 0.80, 0.85); for women, these were HEI-2010 HR: 0.77 (95% CI: 0.74, 0.80), AHEI-2010 HR: 0.76 (95% CI: 0.74, 0.79), aMED HR: 0.76 (95% CI: 0.73, 0.79), and DASH HR: 0.78 (95% CI: 0.75, 0.81). Similarly, high adherence on each index was protective for CVD and cancer mortality examined separately. These findings indicate that multiple scores reflect core tenets of a healthy diet that may lower the risk of mortality outcomes, including federal guidance as operationalized in the HEI-2010, Harvard's Healthy Eating Plate as captured in the AHEI-2010, a Mediterranean diet as adapted in an Americanized aMED, and the DASH Eating Plan as included in the DASH score.

Project description:Background:Diet-quality indexes have been associated with a lower risk of chronic disease mortality in Western populations, but it is unclear whether these indexes reflect protective dietary patterns in Asian populations. Objective:We examined the association between Alternative Healthy Eating Index-2010 (AHEI-2010), alternate Mediterranean diet (aMED), Dietary Approaches to Stop Hypertension (DASH), and Healthy Diet Indicator (HDI) scores and the risk of all-cause cardiovascular disease (CVD), cancer, and respiratory disease mortality. Methods:We used data from a prospective cohort of 57,078 Singapore Chinese men and women (aged 45-74 y) who were free of cancer and CVD at baseline (1993-1998) and who were followed up through 2014. The diet-quality index scores were calculated on the basis of data from a validated 165-item food-frequency questionnaire. Cox regression models with adjustment for potential confounders including sociodemographic and lifestyle variables, body mass index, and medical history were used to estimate HRs and 95% CIs. Results:During a total of 981,980 person-years of follow-up, 15,262 deaths (CVD: 4871; respiratory: 2690; and cancer: 5306) occurred. Comparing the highest with the lowest quintiles, the multivariable adjusted HRs (95% CIs) for all-cause mortality were 0.82 (0.78, 0.86) for AHEI-2010, 0.80 (0.76, 0.85) for aMED, 0.80 (0.75, 0.84) for DASH, and 0.88 (0.83, 0.92) for HDI scores (all P-trend < 0.001). Higher diet index scores were associated with a 14-28% lower risk of CVD and respiratory mortality, but only a 5-12% lower risk of cancer mortality. Higher consumption of vegetables, fruit, nuts, and long-chain n-3 (?-3) fatty acids, lower consumption of red meat, and avoidance of high alcohol consumption were the diet index components associated with a lower risk of mortality. Conclusion:Adherence to several recommended dietary patterns that emphasize healthy plant-based foods was associated with a substantially lower risk of chronic disease mortality in an Asian population. The Singapore Chinese Health Study was registered at www.clinicaltrials.gov as NCT03356340.
