[BDSP. Notice produite par INIST EqFnZR0x. Diffusion soumise à autorisation]. Several studies have reported increased mortality risk with early natural menopause. More recently, mortality risk was reported to be reduced among women who gave birth at age>40 years. The association between reproductive history and mortality was explored among 826 women in a prospective study involving 18,959 person-years of follow-up (from age 50 to 1990-1991) and 108 deaths. After adjustment for age and other covariates, the risk ratio among parous women was 1.53 (95% confidence interval : 0.58,4.07) for natural menopause at age =51 years. In contrast to a previous report, however, the highest estimated mortality risk was seen among women who gave birth in their forties (adjusted risk ratio=2.14,95% confidence interval : 1.05,4.38) compared with having a last birth at ages 30-34 years.
