Behavioral Therapy Of Obstetric Sphincter Tears

The primary aim of the "BOOST Cohort Study" is to determine the incidence of FI symptoms at 6
and 12 weeks postpartum in primiparous women sustaining an OASI.

Secondary aims of the cohort study are:

1. To determine the incidence rates of FI symptoms at 24 weeks post delivery in primiparous
women sustaining an OASI

2. To examine the relationship between the modified WHO sphincter tear classification types
and FI symptoms

3. To examine predictors (socio-demographic, physical and clinical) associated with WHO
sphincter tear classifications (3a, 3b and 4) and predictors associated with FI symptoms

4. To evaluate the incidence of fecal urgency and flatal incontinence at 24 weeks
postpartum in primiparous women sustaining an OASI.

Inclusion Criteria Assessed by 2 weeks postpartum

1. Vaginal delivery >= 28 weeks singleton gestation

2. Documented repair to the anal sphincter at delivery

3. First vaginal delivery

4. Ambulatory

5. Able to give informed consent 6 Adult women >= 18 years of age

Inclusion Criteria at 2 weeks postpartum

1. Inflammatory bowel disease (e.g., ulcerative colitis or Crohn's disease)

2. Pre-pregnancy ano-rectal surgery (e.g., surgery for hemorrhoids, fissures,
sphincterotomy)

3. Pre-pregnancy FI (defined as the leakage of liquid/solid stool and mucus >= once per
month for at least 12 weeks prior to this pregnancy)

4. Neurological condition that would predispose to FI (e.g., spinal cord injury, multiple
sclerosis)

5. Presence of rectovaginal fistula

6. Any participation in other pharmacologic or behavioral studies for FI

7. Previous pregnancy >=28 weeks delivered vaginally or by Cesarean section
