Predictors for sexual dysfunction in the first year postpartum: A systematic review and meta-analysis.

BACKGROUND

Pregnancy and childbirth increase the risk for pelvic floor dysfunction, including sexual dysfunction. So far, the mechanisms and the extent to which certain risk factors play a role remain unclear.

OBJECTIVES

In this systematic review of the literature we aimed to determine risk factors for sexual dysfunction in the first year after childbirth.

SEARCH STRATEGY: We searched MEDLINE, Embase and CENTRAL using the search strategy: sexual dysfunction AND obstetric events.

SELECTION CRITERIA: We included original, comparative studies, reported in English, that used validated questionnaires and the ICS/IUGA terminology for sexual dysfunction, dyspareunia and vaginal dryness.

DATA COLLECTION AND ANALYSIS: We assessed the quality and the risk of bias of the included studies with the Newcastle-Ottawa scale. We extracted the reported data and we performed random-effects meta-analysis to obtain the summary odds ratios (ORs) with 95% confidence intervals (95% CIs). Heterogeneity across studies was assessed using the I2 statistic.

MAIN

RESULTS

Anal sphincter injury was associated with increased odds for both sexual dysfunction (OR 3.00, 95%CI 1.28-7.03) and dyspareunia (OR 1.92, 95% CI 1.47-2.52). Episiotomy was associated with dyspareunia (OR 1.64, 95% CI 1.25-2.14), but not with sexual dysfunction (OR 1.90, 95% CI 0.94-3.84). Compared with spontaneous birth, caesarean section reduced the odds for dyspareunia (OR 0.68, 95% CI 0.54-0.86) but not for sexual dysfunction (OR 1.14, 95% CI 0.89-1.46). Instrumental vaginal birth increased the odds for sexual dysfunction (OR 1.70, 95% CI 1.05-2.76), yet no difference was found for dyspareunia (OR 1.82, 95% CI 0.88-3.75). One study of low quality reported on vaginal dryness and found no association with obstetric events.

CONCLUSIONS

Perineal trauma, rather than mode of birth, increases the odds for sexual dysfunction in the first year after childbirth.

TWEETABLE ABSTRACT: Perineal trauma, rather than mode of birth, correlates with sexual dysfunction and dyspareunia postpartum. #dyspareunia #OASI #episiotomy.
