A first-time mother’s risk of pelvic floor disorders is strongly associated with how her baby is delivered, according to a study funded by the National Institutes of Health. Pelvic floor disorders are thought to result from weakening or injury of the muscles, ligaments and connective tissue in the lowest part of the pelvis. The study, funded by NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development, was led by Victoria Handa, M.D., of Johns Hopkins Bayview Medical Center, Baltimore, and appears in the Journal of the American Medical Association.
Researchers enrolled more than 1,500 women into the study after their first birth; 778 of the women delivered by cesarean, 565 by spontaneous vaginal delivery, and 185 by operative vaginal birth (delivery assisted by forceps or other devices to extract the fetus). After up to nine years of observation, researchers found that women who delivered by Cesarean were at approximately half the risk of developing stress urinary incontinence (incontinence resulting after a cough, sneeze or other activity) and overactive bladder, compared to women who had a spontaneous vaginal birth. Their risk of pelvic organ prolapse (when the cervix and uterus drop into the vagina and protrude through the vaginal opening) was 70-percent lower, compared to the same group. Women who had operative vaginal delivery were almost twice as likely to experience anal incontinence and pelvic organ prolapse, compared to those who delivered by cesarean.
