ObjectivesWe performed a systematic review and dose-response meta-analysis to assess the association of total sugars, added sugars, fructose, and sucrose with all-cause, cardiovascular disease (CVD), and cancer mortality.MethodsWe searched PubMed, Embase, and Web of Science for prospective cohort studies up to May 10, 2022. Pooled relative risks and 95% CIs were calculated by random effect models, and the linear and non-linear dose-response associations were explored by restricted cubic splines.ResultsComparing the highest with the lowest categories of total sugars, the summary RR was 1.09 (95% CI, 1.02-1.15; I2 = 71.9%) for all-cause mortality, 1.10 (1.02-1.18; I2 = 12.7%) for CVD mortality, and 1.00 (0.94-1.05; I2 = 0) for cancer mortality. For fructose, the summary relative risk was 1.09 (1.03-1.16; I2 = 58.4%) for all-cause mortality, 1.11 (1.03-1.20; I2 = 37.4%) for CVD mortality, and 1.00 (0.95-1.06; I2 = 0) for cancer mortality. Restricted cubic splines found non-linear associations of total sugars and fructose with all-cause and CVD mortality (P for non-linearity < 0.001). A significant increment in risk of all-cause and CVD mortality was observed with >10% energy intake to 20% energy intake for total sugars and fructose. No association was found for the added sugars and sucrose with all-cause, CVD, and cancer mortality.ConclusionsIncreased intake of total sugars and fructose is associated with all-cause and CVD mortality but not associated with cancer mortality, which could have implications for guideline recommendations regarding the risk of mortality related to sugar intake.Copyright © 2023.
