Cholesterol and Egg Intakes, and Risk of Hypertension in a Large Prospective Cohort of French Women.

ABSTRACT: Purpose: The relationship between egg and cholesterol intakes, and cardiovascular disease is controversial. Meta-analyses indicate that egg consumption is associated with increased cardiovascular disease and mortality, but reduced incidence of hypertension, a major risk factor for cardiovascular disease. This study aims to investigate the associations between consumption of egg and cholesterol, and hypertension risk in a cohort of French women. Methods: We used data from the E3N cohort study, a French prospective population-based study initiated in 1990. From the women in the study, we included those who completed a detailed diet history questionnaire, and who did not have prevalent hypertension or cardiovascular disease at baseline, resulting in 46,424 women. Hypertension cases were self-reported. Egg and cholesterol intake was estimated from dietary history questionnaires. Cox proportional hazard models with time-updated exposures were used to calculate hazard ratios. Spline regression was used to determine any dose-respondent relationship. Results: During 885,321 person years, 13,161 cases of incident hypertension were identified. Higher cholesterol consumption was associated with an increased risk of hypertension : HRQ1-Q5 = 1.22 [1.14:1.30], with associations similar regarding egg consumption up to seven eggs per week: HR4-7 eggs = 1.14 [1.06:1.18]. Evidence for a non-linear relationship between hypertension and cholesterol intake was observed. Conclusion: Egg and cholesterol intakes were associated with a higher risk of hypertension in French women. These results merit further investigation in other populations.

Project description:Epidemiological and experimental evidence support a protective effect of dietary polyphenols on chronic diseases, but high quality longitudinal data are needed, including details on categories of polyphenols. Our objective was to investigate the prospective association between total and individual classes and subclasses of dietary polyphenols and the risk of major cardiovascular disease in the NutriNet-Santé cohort. A total of 84,158 participants, who completed at least three 24 h dietary records, were included between May 2009 and June 2017. Individual polyphenols intakes were obtained by matching food consumption data from the 24 h dietary records with the Phenol-Explorer polyphenol composition database. Multivariable Cox proportional hazards models were used to characterize the associations between dietary polyphenols and the incidence of cardiovascular diseases, comparing tertile T3 vs. T1 of classes and subclasses of polyphenols. Over a median of 4.9 years of follow-up, 602 major cardiovascular events were diagnosed. Intakes of anthocyanins, catechins, and flavonols were strongly inversely associated with cardiovascular disease risk (anthocyanins: Hazard Ratio (HR)for a 1-point increment of 10 mg/day = 0.98 (0.96⁻0.99, p = 0.03, HRT3vs.T1 = 0.66 (0.52⁻0.83), ptrend = 0.0003; catechins: HRfor a 1-point increment of 10 mg/day = 0.98 (0.96⁻0.99), p = 0.02, HRT3vs.T1 = 0.74 (0.60⁻0.91), ptrend = 0.004; flavonols: HRfor a 1-point increment of 10 mg/day = 0.94 (0.90⁻0.99), p = 0.02, HRT3vs.T1 = 0.75 (0.61⁻0.94), ptrend = 0.006). Intakes of dihydrochalcones, proanthocyaninidins, dihydroflavonols, hydroxybenzoic acids, and stilbenes were also associated with a decrease (13%, 19%, 24%, 24%, and 27%, respectively) in cardiovascular disease risk, when comparing tertile T3 to T1. Higher intakes of polyphenols, especially of anthocyanins, catechins, and flavonols, were associated with a statistically significant decreased cardiovascular disease risk.

Project description:ObjectiveTo evaluate the association between egg intake and cardiovascular disease risk among women and men in the United States, and to conduct a meta-analysis of prospective cohort studies.DesignProspective cohort study, and a systematic review and meta-analysis of prospective cohort studies.SettingNurses' Health Study (NHS, 1980-2012), NHS II (1991-2013), Health Professionals' Follow-Up Study (HPFS, 1986-2012).ParticipantsCohort analyses included 83?349 women from NHS, 90?214 women from NHS II, and 42?055 men from HPFS who were free of cardiovascular disease, type 2 diabetes, and cancer at baseline.Main outcome measuresIncident cardiovascular disease, which included non-fatal myocardial infarction, fatal coronary heart disease, and stroke.ResultsOver up to 32 years of follow-up (>5.54 million person years), 14?806 participants with incident cardiovascular disease were identified in the three cohorts. Participants with a higher egg intake had a higher body mass index, were less likely to be treated with statins, and consumed more red meats. Most people consumed between one and less than five eggs per week. In the pooled multivariable analysis, consumption of at least one egg per day was not associated with incident cardiovascular disease risk after adjustment for updated lifestyle and dietary factors associated with egg intake (hazard ratio for at least one egg per day v less than one egg per month 0.93, 95% confidence interval 0.82 to 1.05). In the updated meta-analysis of prospective cohort studies (33 risk estimates, 1?720?108 participants, 139?195 cardiovascular disease events), an increase of one egg per day was not associated with cardiovascular disease risk (pooled relative risk 0.98, 95% confidence interval 0.93 to 1.03, I2=62.3%). Results were similar for coronary heart disease (21 risk estimates, 1?411?261 participants, 59?713 coronary heart disease events; 0.96, 0.91 to 1.03, I2=38.2%), and stroke (22 risk estimates, 1?059?315 participants, 53?617 stroke events; 0.99, 0.91 to 1.07, I2=71.5%). In analyses stratified by geographical location (P for interaction=0.07), no association was found between egg consumption and cardiovascular disease risk among US cohorts (1.01, 0.96 to 1.06, I2=30.8%) or European cohorts (1.05, 0.92 to 1.19, I2=64.7%), but an inverse association was seen in Asian cohorts (0.92, 0.85 to 0.99, I2=44.8%).ConclusionsResults from the three cohorts and from the updated meta-analysis show that moderate egg consumption (up to one egg per day) is not associated with cardiovascular disease risk overall, and is associated with potentially lower cardiovascular disease risk in Asian populations.Systematic review registrationPROSPERO CRD42019129650.
