Title Intergenerational predisposition to operative delivery.
Date 1996-06
Description OBJECTIVE: To determine the risk of cesarean delivery for women who themselves were born via operative delivery. METHODS: A linked data base was constructed between the birth certificates of individuals born in Utah during 1947-1957 (parental cohort) and who subsequently became a parent of offspring born in Utah between 1970-1991 (offspring cohort). Parental cohort women (cases) who had been delivered operatively (cesarean delivery, mid- or high forceps) as well as women who had a sibling delivered by an operative procedure were matched (1:2) with parental-cohort women born by spontaneous vaginal delivery (controls). Both cases and controls were selected based on having a record of at least one delivery in Utah during 1970-1991. RESULTS: Women who were delivered by cesarean were at increased risk of subsequently delivering their children by cesarean (odds ratio [OR] 1.41, 95% confidence interval [CI] 1.18-1.70; P < .001). Progressive risk was associated with parental delivery by mid- or high forceps (OR 1.72, 95% CI 1.20-2.47; P = .004), parental cesarean because of cephalopelvic disproportion alone (OR 1.83, 95% CI 1.16-2.88; P = .01), or parental cesarean for dysfunctional labor (OR 5.97, 95% CI 1.5-23.6; P < .001). The attributable risk for cesarean delivery to the contemporary population is 3.5%. CONCLUSION: An intergenerational predisposition to cesarean delivery exists.
