Data are means with 95 percent confidence intervals in parentheses unless otherwise indicated (SF-36 scoring: the MCS and PCS are scored from 0 to100, with increasing score for increasing quality of life; No incontinence = no reported fecal incontinence in the past 12 months; Less than monthly = at least 1 fecal incontinent episode per year but not monthly; Monthly = at least 1 fecal incontinent episode per month but not weekly; Weekly = at least 1 incontinent episode per week).

SF-36 MCS = Medical Outcome Short Form-36 Mental Component Score; SF-36 PCS = Medical Outcome Short Form-36 Physical Component Score.

P values are based on tests for trend.

Adjusted for race, age, body mass index, self-reported health status, irritable bowel syndrome, current smoker, menopause status, pelvic organ prolapse, ≥1 urinary tract infection in the past year and pelvic organ prolapse surgery.

Adjusted for race, age, body mass index, self-reported health status, chronic obstructive pulmonary disease, irritable bowel syndrome, weekly urinary incontinence, ≥1 urinary tract infection in the past year, pelvic organ prolapse surgery and cholecystectomy.
