Abstract
Objectives The effect of dietary cholesterol consumption on health effects and serum lipids remains controversial. This study aimed to examine the association of dietary cholesterol trajectories over 14 years in China with the risk of cardio-metabolic diseases and all-cause mortality and serum lipids. Methods This study used weighted longitudinal data of 8952 adults from the China Health and Nutrition Survey, and subgroup analyses included 5466 adults who provided blood samples. Latent class trajectory modelling was performed to examine cholesterol trajectories. Cox regression models and general linear regressions were performed to examine the association between trajectories and outcomes. Results Compared to the participants with persistently low dietary cholesterol intake, participants with gradually increasing cholesterol intake throughout adulthood were more likely to have hypertension (HR = 1.14, 95% CI: 1.03, 1.28) and to die due to all causes (HR = 2.19, 95% CI: 1.57, 3.05). Moreover, participants with persistently high cholesterol intake were more likely to die due to all causes (HR = 2.26, 95% CI 1.47, 3.47). The total cholesterol (TC):HDL-cholesterol (HDL-C) ratio and apolipoprotein B (ApoB) in these two groups were also significantly elevated compared to the group with persistently low dietary cholesterol intake (all P < 0.05). An association between trajectories of cholesterol and the incidence of diabetes was also observed; however, such an association became non significant after additional adjustment for other nutrients, food consumption and social environment. Conclusions Gradually increasing or persistently high cholesterol consumption throughout adulthood was significantly associated with an increased risk of hypertension and all-cause mortality with elevated serum lipids.This publication has 34 references indexed in Scilit:
