Childhood cardiovascular health and subfertility: the Bogalusa Heart Study.

ABSTRACT: BACKGROUND:Although childhood cardiovascular risk can contribute to adult cardiovascular disease, and fertility and adult cardiovascular health are linked, the association between early-life cardiovascular risk and female infertility has not been studied. METHODS:A total of 1799 women participated in the Babies substudy of the Bogalusa Heart Study. Systolic blood pressure (SBP), diastolic blood pressure (DBP), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides, glucose, and insulin were age-standardized and examined as predictors of self-reported fertility difficulties using multivariable logistic regression with adjustment for confounders. Polycystic ovarian syndrome (PCOS) was assessed via a report of diagnosis and symptoms, using a validated questionnaire. RESULTS:Women with a history of PCOS were more likely to report fertility difficulties. Childhood and adolescent cardiovascular risk factors were generally not associated with fertility indicators, although childhood LDL (aOR 1.38 per one-SD increase, 0.97-1.96) and total cholesterol (aOR 1.49, 1.06-2.11) were raised in those who never became pregnant. Pre-pregnancy risk SBP (overall fertility, aOR 1.49, 1.00-2.23) and glucose levels (ever tried but unable, aOR 2.65, 1.39-5.06) were associated with an increased risk of some infertility indicators. These results were largely unaffected by exclusion of women with PCOS. CONCLUSION:Some childhood and pre-pregnancy cardiovascular risk factors are associated with adult subfertility.
