Abstract

To understand the nature of bowel disturbance in patients with dyssynergia, we prospectively examined demographics, stool patterns, and quality of life by administering a 31-item questionnaire to 120 patients who fulfilled symptomatic and manometric criteria for dyssynergia (Rome II). Data from 118 subjects (M/F = 27/91) was analyzed. Eighty four percent of patients reported excessive straining, and 76% reported feeling of incomplete evacuation; 9.7% had no urge to defecate. Abdominal bloating was reported by 74%. More women than men reported infrequent bowel movements and need to strain excessively (P < 0.05). Forty eight percent of patients, more women (P < 0.05) than men used digital maneuvers to evacuate. Hard stools was reported by 60% of women and 41% of men. Sexual abuse was reported by 22%; 21% were women (P = 0.02). Physical abuse was reported by 32%. Bowel problem adversely affected family life in 33%, sexual life in 56%, work life in 69% and social life in 76% of patients. Most patients with dyssynergia reported an excessive need to strain, feeling of incomplete evacuation and abdominal bloating and one half used digital maneuvers. It significantly affected quality of life, particularly in women.

An epidemiological survey of constipation in canada: definitions, rates, demographics, and predictors of health care seeking.

P Pare, S Ferrazzi, W G Thompson … (2001)

The prevalence of functional constipation is highly variable among epidemiological surveys and may relate to the definitions applied. We estimated the population prevalence of self-reported, Rome I-defined, and Rome II-defined constipation in Canada and determined the variables that best predicted health care seeking. A research firm was employed to conduct a random digit dial national survey, inviting household members at least 18 yr of age to participate in a study assessing personal health issues. The sample was stratified to ensure that each region of Canada was represented. Data collection involved three stages: 1) recruitment of participants by phone, 2) mailing of the questionnaire, and 3) data retrieval through a follow-up phone call. The Rome II questionnaire was used to derive the prevalence of functional constipation using both Rome I and Rome II criteria. Of the 1149 participants, 27.2% self-reported constipation within the past 3 months, and 16.7% and 14.9% had functional constipation according to Rome I and II, criteria, respectively. For all three definitions, the rate for women was close to twice that for men. Approximately 34% of those with self-reported constipation had visited a physician for it, versus 26.3% of Rome II subjects. In a regression model, subjects self-reporting in the past 3 months were more likely to have seen a doctor for their constipation (odds ratio 2.47, p < 0.01) and significantly more women than men (35.6% vs 19.5%, p < 0.05). Functional constipation and related health care seeking are common in the Canadian population and are strongly determined by the definition used. The Rome II criteria for this disorder seem to be satisfactory, but modifications may be considered to allow for constipated subjects taking laxatives and to increase the number of qualifying symptoms.

Sexual and physical abuse in women with functional or organic gastrointestinal disorders.

T Toomey, Jacqueline C Mitchell, G. Nachman … (1990)

To determine the prevalence of a history of sexual and physical abuse in women seen in a referral-based gastroenterology practice, to determine whether patients with functional gastrointestinal disorders report greater frequencies of abuse than do patients with organic gastrointestinal diseases, and to determine whether a history of abuse is associated with more symptom reporting and health care utilization. A consecutive sample of women seen in a university-based gastroenterology practice over a 2-month period was asked to complete a brief questionnaire. The self-administered questionnaire requested information about demographics, symptoms, health care utilization, and history of abuse. Physicians indicated the primary diagnosis for each patient and whether she had ever discussed having been sexually or physically abused. Of 206 patients, 89 (44%) reported a history of sexual or physical abuse in childhood or later in life; all but 1 of the physically abused patients had been sexually abused. Almost one third of the abused patients had never discussed their experiences with anyone; only 17% had informed their doctors. Patients with functional disorders were more likely than those with organic disease diagnoses to report a history of forced intercourse (odds ratio, 2.08; 95% CI, 1.03 to 4.21) and frequent physical abuse (odds ratio, 11.39; CI, 2.22 to 58.48), chronic or recurrent abdominal pain (odds ratio, 2.06; CI, 1.03 to 4.12), and more lifetime surgeries (2.7 compared with 2.0 surgeries; P less than 0.03). Abused patients were more likely than nonabused patients to report pelvic pain (odds ratio, 4.05; CI, 1.41 to 11.69), multiple somatic symptoms (7.1 compared with 5.8 symptoms; P less than 0.001), and more lifetime surgeries (2.8 compared with 2.0 surgeries; P less than 0.01). We found that a history of sexual and physical abuse is a frequent, yet hidden, experience in women seen in referral-based gastroenterology practice and is particularly common in those with functional gastrointestinal disorders. A history of abuse, regardless of diagnosis, is associated with greater risk for symptom reporting and lifetime surgeries.

Epidemiology of constipation (EPOC) study in the United States: relation of clinical subtypes to sociodemographic features.

W F Stewart, J Liberman, R Sandler … (1999)

Constipation is a common heterogeneous condition, possibly encompassing different clinical subtypes. Little is known about the comparative epidemiology of constipation subtypes. This study was conducted to estimate the prevalence of constipation subtypes and determine whether subtypes differ by sociodemographic factors. Between June and September 1997, a telephone interview was conducted with individuals about their bowel habits in the preceding 3 months. Survey data on 15 constipation-related symptoms were used to identify individuals who met prespecified symptom criteria for the following mutually exclusive subgroups: functional constipation, irritable bowel syndrome (IBS), outlet obstruction or delay (outlet), both IBS and outlet (IBS-outlet), and frequent laxative users (i.e., at least every other day). A total of 10,018 eligible individuals in the United States 18 yr of age or older completed the interview. Test-retest reliability of reporting symptoms was assessed in a separate national survey. The Spearman's correlation coefficient for reporting symptoms ranged from 0.54 to 0.83; all but three symptoms had correlations above 0.68. The overall prevalence of constipation was 14.7%. By subtype, prevalence was 4.6% for functional, 2.1% for IBS, 4.6% for outlet, and 3.4% for IBS-outlet. An additional 1.8% of respondents reported laxative use at least every other day. Outlet was the most common subtype among women, whereas functional constipation was the most common subtype among men. The gender ratio varied by subtype, with elevated ratios for outlet (F/M = 1.65) and IBS-outlet (F/M = 2.27) subtypes. The age pattern differed among each of the four subtypes. Prevalence of functional subtype decreased with increasing age. In contrast, outlet subtype did not seem to vary by age, and IBS (both men and women) and IBS-outlet (women only) subtypes increased to age 35 yr and declined thereafter. Prevalence of functional constipation increased with increasing education. Outlet type was more common in nonwhites compared to whites. Finally, 45% of individuals with constipation reported having the condition for 5 yr or more. Constipation is a heterogeneous condition. Differences in epidemiological profile by age, sex ratio, and relation to other sociodemographical factors support the distinction of two and possibly more symptom-based subtypes.
