Introduction
We describe pelvic floor function in nulliparous pregnant women.
Materials/Methods
Nulliparous midwifery patients completed the Incontinence Severity Index (ISI), Pelvic Floor Impact Questionnaire (PFIQ-7), Wexner Fecal Incontinence Scale (W), and answered questions about sexual activity and perineal pain at baseline during the first (T1), second (T2), or third trimester (T3) and repeated in late T3. They also underwent a Pelvic Organ Prolapse Quantification (POPQ) exam at their baseline visit. Data were compared across trimesters. ANOVA and logistic regression accounted for repeated measures and was controlled for age and education.
Results
We recruited 627 women. In T1, 124 women gave baseline data and completed questionnaires, 403 in T2, and 96 in early T3 (496 repeated questionnaires in later T3). Besides an increase in genital hiatus and perineal body (all adjusted p < .05), physical exam measures did not differ between trimesters. As pregnancy progressed, urinary incontinence (UI) (T1=33, T2=44, T3=69% women with ISI >0, all comparisons p<.02) and IIQ-7 scores increased. Fecal incontinence (FI) increased (T1=8, T2=15, T3=16% from T2 to T3, p=.04), while CRAIQ-7 scores did not increase. Perineal pain increased (T1=17, T2=18 and T3 = 40%, all adjusted p <.001), and sexual activity decreased as pregnancy progressed (T1= 94, T2 = 90, T3 = 77% sexually active, T1 vs T3 and T2 vs T3, p <.001).
Conclusions
During pregnancy, women experience worsening UI, FI and perineal pain. UI symptoms are associated with a negative impact on quality of life. Sexual activity decreases and POPQ stage does not change.
