Abstract
Background: This study aims to investigate whether food consumed time and distribution at three-meals is associated with long-term survival among the people with diabetes. Methods:This study included 4,699 diabetes patients participating in the National Health and Nutrition Examination Survey from 2003 to 2014. Food consumed across a day including the forenoon, afternoon, evening, were divided into quantiles based on their distribution. Cox proportional hazards regression models were used to analyze the survival relationship between food intakes time and distribution (with a constant quality and quantity) and mortality. Results:After adjustment for multiple covariates, in the forenoon, compared to the participants with diabetes in the lowest consumption quantile of potato and starchy-vegetable, participants with diabetes in the highest consumption quantile had lower mortality risk of CVD(HRpotato=0.52, 95%CI: 0.38-0.87; HRstarchy-vegetable= 0.51, 95%CI: 0.29-0.90). In the evening, the highest quantile of dark-vegetable intake is related to lower mortality risk of CVD(HR=0.64, 95%CI: 0.45-0.92) and all-cause(HR=0.81, 95%CI: 0.66-0.99), whereas participants in the highest quantile of intakes of refined grain and processed meat are more likely to die due to CVD(HRrefined-grain=1.54, 95%CI:1.10-2.15; HRprocessed-meat=1.83, 95%CI:1.20-2.77) and all-cause(HRrefined-grain=1.29, 95%CI:1.01-1.65; HRprocessed-meat=1.37, 95%CI:1.06-1.75). Iso-calorically switching 0.1 serving refined grain or processed meat consumed in the evening to the forenoon, and 0.1 serving dark vegetable consumed in the afternoon to the evening reduced the risk of CVD mortality.Conclusions:Higher intake of potato, starchy-vegetable in forenoon, dark-vegetable in the evening, and lower intake of refined-grain and processed-meat in the evening was associated with better long-term survival in people with diabetes.
