Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study design will be a cohort study to determine the incidence of FI symptoms at 6, 12 and 24 weeks postpartum in primiparous women sustaining an OASI. At 6, 12 and 24 weeks postpartum, subjects will be contacted by telephone for evaluation of FI symptoms. Symptoms of FI will be defined by at least monthly symptoms of leakage of liquid, solid stool, and mucus. Flatal incontinence will be assessed at 24 weeks, based on the Fecal Incontinence Severity Index, and fecal urgency will be assessed at 24 weeks based on the one question from the Modified Manchester questionnaire. A sample size of approximately 400-450 subjects will be enrolled.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Primiparous women with an obstetric anal sphincter tear

Subjects in this trial will be primiparous women who underwent anal sphincter repair at the time of a singleton vaginal delivery. Sphincter tears will be clinically characterized at the time of delivery as \<50% tear through the anal sphincter (modified WHO 3a), \>50% (modified WHO 3b), or complete tear through the anal sphincter (4th degree). Subjects in this study will not have receive study interventions.

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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)
