摘要
Epidemiology and risk factors of hemorrhoidal disease are not well defined. Aims and methods-Past history and events occuring during the last two weeks before a medical visit for acute hemorrhoidal symptoms were analyzed and compared with controls consulting for any other diagnosis without exclusion. Results-Among complete inquiries returned by 931 private gastroenterologists, files from 1033 patients (542 males) and 1028 controls (504 males) were randomly selected. Hemorrhoidal disease patients were younger (47 ±14.5 vs. 52 ±16.5 yrs; P < 0.0001);sex ratio was not different from controls. Factors significantly associated with hemorrhoidal crisis were: past history of hemorrhoidal symptoms, age < 50 yrs, past history of anal fissure, occupational activity (OR 5.17; 1.95; 1.72; 1.43; P < 0.1) and recent unusual events : spicy diet, constipation, physical activity, alcohol intake (OR 4.95; 3.93; 2.79; 1.99; P < 0.1). Stress protected against hemorrhoids (OR 0.49; P < 0.0001). For women aged less than 40 yrs, no significant risk factor related with genital activity was found for hemorrhoidal disease. Conclusion-For young patients, especially those with a past hemorrhoidal history, spice or alcohol intake and constipation are risk factors for hemorrhoidal crisis. For young women, prevention is essentialy based on treatment of constipation associated with genito-obstetrical events.
Epidemiology and risk factors of hemorrhoidal disease are not well defined. Aims and methods- Past history and events occuring during the last two weeks before a medical visit for acute hemorrhoidal symptoms were analyzed and compared with controls consulting for any other diagnosis without exclusion. Results -Among complete inquiries returned by 931 private gastroenterologists, files from 1033 patients （542 males） and 1028 controls （50.4 males） were randomly selected. Hemorrhoidal disease patients were younger （47 4±14.5vs.52 4±16.5yrs; P〈0.0001）;sex ratio was not different from controls. Factors significantly associated with hemorrhoidal crisis were： past history of hemorrhoidal symptoms, age 〈 50 yrs, past history of analfissure, occupational activity （OR 5. 17; 1.95; 1.72; 1.43; P 〈 0. 1） and recent unusual events ： spicy diet, constipation, physical activity, alcohol intake （OR 4.95; 3.93; 2. 79; 1.99; P 〈 0. 1）. Stress protected against hemorrhoids （OR 0. 49; P 〈 0. 0001）. For women aged less than 40 yrs, no significant risk factor related with genital activity was found for hemorrhoidal disease.
