INTRODUCTION: Exact data on the prevalence of hemorrhoids are rare. Therefore, we designed a study to investigate the prevalence of hemorrhoids and associated risk factors in an adult general population. METHODS: Between 2008 and 2009, consecutive patients were included in a prospective study. They attended the Austrian national wide health care program for colorectal cancer screening at four medical institutions. A flexible colonoscopy and detailed examination were conducted in all patients. Hemorrhoids were defined according to a standardized grading system. Independent variables included baseline characteristics, sociodemographic data, and health status. Potential risk factors were calculated by univariate and multivariate analysis. RESULTS: Of 976 participants, 380 patients (38.93%) suffered from hemorrhoids. In 277 patients (72.89%), hemorrhoids were classified as grade I, in 70 patients (18.42%) as grade II, in 31 patients (8.16%) as grade III, and in 2 patients (0.53%) as grade IV. One hundred seventy patients (44.74%) complained about symptoms associated with hemorrhoids, whereas 210 patients (55.26%) reported no symptoms. In the univariate and multivariate analysis, body mass index (BMI) had a significant effect on the occurrence of hemorrhoids with p = 0.0391 and p = 0.0282, respectively. Even when correcting for other potential risk factors, an increase in the BMI of one increased the risk of hemorrhoids by 3.5%. CONCLUSION: Hemorrhoids occur frequently in the adult general population. Notably, a considerable number of people with hemorrhoids do not complain about symptoms. In addition, a high BMI can be regarded as an independent risk factor for hemorrhoids.
