Fecal incontinence was defined as the loss of liquid, solid, or mucus stool occurring at least monthly on a validated questionnaire. A gender-specific sexual behavior questionnaire assessed any anal intercourse via an audio computer-assisted personal interview.
Prevalence estimates and prevalence odds ratios PORs were analyzed in adjusted multivariable models using appropriate sampling weights. RESULTS Overall, 4, adults aged 20—69 years 2, women and 2, men completed sexual behavior questionnaires and responded to fecal incontinence questions. Anal intercourse was higher among women Fecal incontinence rates were higher among women 9.
After multivariable adjustment for other factors associated with fecal incontinence, anal intercourse remained a predictor of fecal incontinence among women POR: Men engaged in anal intercourse may have lower manometry pressures than men not engaged in anal intercourse; however, few studies have examined fecal incontinence FI symptoms and anal intercourse 5 , 6.
Although specific sexual practices of women with FI are undescribed, women with FI are as likely to be sexually active as women without FI but their sexual function scores are lower 7 , 8. Studies evaluating the impact of FI treatment on sexual function are limited to descriptions in small populations following sphincteroplasty, with most studies reporting improved function and less embarrassment with sexual activity following treatment for FI 9 — The primary aim of this study was to determine if anal intercourse is associated with reports of FI, defined as the accidental loss of liquid, solid, or mucus stool occurring at least monthly.
Secondary aims were i to characterize the prevalence of anal intercourse in a nationally representative sample of non-institutionalized US adults aged 20—69 years and ii to assess the relationship of anal intercourse with other known factors associated with FI, such as age, comorbid diseases, depression, and stool consistency.
We hypothesized that both women and men who engaged in anal intercourse would have higher rates of FI. The National Center for Health Statistics NCHS ethics review board approved the survey protocols, and all participants provided written informed consent. Questions specific to anal intercourse were administered to men and women aged 18—69 years.
Women who were pregnant were excluded from the analysis. Questions about bowel symptoms were ascertained in the mobile examination center interview room using a computer-assisted personal interview system. Questions about sexual behaviors were ascertained in a private mobile examination center interview room using an audio computer-assisted personal interview system.
Our final analytic sample included 4, adults aged 20—69 years who answered questions about anal intercourse and FI Figure 1.
