| Résumé : | [BDSP. Notice produite par INIST-CNRS mECBR0xl. Diffusion soumise à autorisation]. In a group of 46,000 North-American Adventist women aged 40 and above, we investigated the relationships between body mass index (BMI, kg/m2) at age 20 and the proportion of women who reported at least one miscarriage, periods with irregular menstruation or failing to become pregnant even if trying for more than one straight year. Approximately 31,14 and 17%, respectively, reported the three different problems related to reproduction. Positive age-and marital status adjusted relationships were found between BMI at age 20 and periods with irregular menstruation or failing to become pregnant even if trying for more than 1 year, but not with the risk of miscarriages. Women with BMI>=32.5 kg/m2 when aged 20 had approximately 2.0 (95% CI : 1.6,2.4) and 1.5 (95% CI : 1.3,1.9) higher odds for irregular periods or failing to get pregnant, respectively, than women with BMI in the 20-24.9 kg/m2 bracket. These relationships were consistently found in a number of strata of the population, including the large proportion of the women who never had smoked or never used alcohol. Underweight (BMI<18.5 kg/m2) when aged 20 marginally (approximately 15%) increased the risk of failing to get pregnant within a year. Thus, obesity at age 20 increases the risk of reporting some specific reproductive problems, but not the risk of miscarriages. |
