•Older age at menarche has been reported to be associated with an increased risk of heart failure.•Body mass index, hypertension and prevalent type 2 diabetes mediated the association between menarche and heart failure risk.•Future studies should phenotype heart failure in more detail, to enable investigation of the different subtypes. Early age at menarche has been reported to be associated with increased risks of developing type 2 diabetes (T2D) and coronary heart disease (CHD) in adulthood, but a late menarche has also been found to be associated with an increased risk of CHD. Both T2D and CHD are important risk factors for developing heart failure (HF). We examined the relationship between age at menarche (AAM) and HF incidence in women from the European Prospective Investigation into Cancer and Nutrition – Netherlands (EPIC-NL) cohort study. The EPIC-NL cohort comprised 28,504 women aged 20–70 years at baseline (1993–1997). Mean age at menarche was 13.3 (standard deviation 1.6) years. During a median follow-up of 15.2 years HF occurred in 631 women. Cox proportional hazard regression models, stratified by cohort and adjusted for potential confounders, were used to investigate the associations between AAM and HF incidence. After confounder adjustment, each year of older age at menarche was associated with a 5% lower risk of HF (hazard ratio 0.95 (95% CI, 0.91–1.00), p-value 0.048). Further adjusting for body mass index (BMI), prevalent CHD, hypertension, or prevalent T2D as potential mediators between early menarche and risk of HF attenuated the associations between AAM and risk of HF to non-significance. Older AAM reduced the risk of HF in this study. BMI, prevalent CHD, hypertension and prevalent T2D seemed to mediate this association. Future research with a longer follow-up should establish whether there is an independent effect of AAM on HF risk. Also, further phenotyping of HF cases is necessary to enable whether the associations differ for the various subtypes of HF.
