To evaluate the association between infertility and fertility treatments on subsequent risk of hypertension.
A total of 116,430 female nurses, followed from 1993 to June 2011, as part of the Nurses’ Health Study II cohort.
Main Outcome Measure(s):
Self-reported, physician-diagnosed hypertension.
Compared with women who have never reported infertility, infertile women were at no greater risk of hypertension (multivariable adjusted relative risk (RR) = 1.01, with 95% confidence interval [CI] [0.94–1.07]). Infertility due to tubal disease was associated with a higher risk of hypertension (RR = 1.15 [1.01–1.31]), but no other diagnoses were associated with hypertension risk, compared with women who did not report infertility (ovulatory disorder: RR = 1.03 [0.94–1.13]; cervical: RR = 0.88 [0.70–1.10]; male factor: RR = 1.05 [0.95–1.15]; other reason: RR = 1.02 [0.94–1.11]; reason not found: RR = 1.02 [0.95–1.10]). Infertile women collectively had 5,070 cases of hypertension. No clear pattern between use of fertility treatment and hypertension was found among infertile women (clomiphene citrate: RR = 0.97 [0.90–1.04]; gonadotropin alone: RR = 0.97 [0.87–1.08]; intrauterine insemination: RR = 0.86 [0.71–1.03]; in vitro fertilization: RR = 0.86 [0.73–1.01]).
Among this relatively young cohort of women, no apparent increase occurred in hypertension risk among infertile women, or among women who had undergone fertility treatment previously.
