Abstract
Background and aims: Current evidence of the association between egg consumption and cardiovascular diseases (CVD) is controversial. We aim to investigate the longitudinal association between egg consumption and the risk of CVD among Chinese adults.
Methods and results: A total of 16,030 adults who attended China Health and Nutrition Survey 1991–2015 were included in this study. Egg consumption was collected with 3-day 24-h recall method supplemented by household inventory record. Cumulative mean egg intake during 1991–2011 were calculated as the habitual intake. CVD incidence was self-reported as being diagnosed by physicians following study entry. The association between egg consumption and incident CVD was examined using Cox regression. The mean age (SD) of the study population was 43.7 (14.8) years and 51% were women. During a 9.9-year (median 9.0) follow up, 663 CVD incidents were reported. The corresponding incident rate (per 1000 person-year) by egg consumption level of none, 1–20, 21–50, and 50+gram/day was 2.6, 4.8, 4.2, 5.5 (P < 0.001) with the unadjusted HR (95% CI) of 1.0, 1.42 (1.12–1.80), 1.31 (1.02–1.67), 2.01 (1.53–2.64). After adjusted for demo socioeconomic, and behaviour factors, egg consumption>50 g/day increased the CVD incident by 43% (HR 1.43, 95% CI 1.02–2.00. BMI, hypertension, and diabetes mediated the association between egg consumption and CVD.
Conclusion: Higher egg intake, as part of the modern dietary pattern high in sugars, fat, and animal-source foods, increased the risk of CVD. The effect of egg on CVD incident was partly mediated by overweight/obesity, hypertension, and diabetes.
