Abstract

BACKGROUND

The prevalence of benign anorectal diseases (BAD) in the general population has been difficult to establish, either because the individual diseases themselves were difficult to characterize in surveys or because of bias in the selection of the survey population. Reported herein is a prevalence survey of BAD symptoms and treatment history of a sample of the general population, selected by random digit dialing.

METHOD

A survey instrument that inquired into symptoms of BAD, BAD treatment history, and health-seeking behaviors was administered by telephone interview with 102 individuals, between the ages of 21 and 65 of both genders and all races, chosen by random digit dialing in the Joliet, Illinois area. For selected variables (gender, education level, obesity, previous BAD treatment, fiber supplementation, time for defecation and reading during defecation all related to BAD symptoms) odds ratios and 95 percent confidence intervals were calculated.

RESULTS

Of the 102 individuals, 9 had been previously treated for hemorrhoids, 4 by surgery, and 5 medically. Twenty individuals currently have BAD symptoms, six of these have multiple symptoms frequently, implying established BAD, and four of these have been previously treated for hemorrhoids. Seven of eight individuals with rectal bleeding in the past year have not sought medical evaluation. Of the associations tested, statistical significance was found only between female gender and BAD symptoms (odds ratio = 4.6; 95 percent confidence interval = 1.3-20.4).

CONCLUSIONS

History of hemorrhoidal treatment and current BAD symptomatology are highly prevalent in a randomly selected population, and 80 percent of the subjects with symptoms of BAD have not consulted a physician regarding BAD. Some previously held correlates of hemorrhoidal symptoms, such as obesity and extended time for defecation, showed no apparent association with hemorrhoid treatment history or current BAD symptoms. The best predictors of current BAD symptoms were female gender (odds ratio = 4.6; 95 percent confidence interval = 1.3-20.4) and previous hemorrhoid treatment (odds ratio = 3.9; 95 percent confidence interval = 0.7-20).

摘要

背景

普通人群中良性肛肠疾病（BAD）的患病率一直难以确定，这要么是因为在调查中个别疾病本身难以特征化，要么是由于调查人群选择存在偏差。本文报告了一项通过随机数字拨号选取的普通人群样本的BAD症状及治疗史患病率调查。

方法

通过电话访谈对伊利诺伊州乔利埃特地区随机数字拨号选取的102名年龄在21至65岁之间、不同性别和种族的个体进行调查，调查工具询问了BAD症状、BAD治疗史及就医行为。针对选定变量（性别、教育水平、肥胖、既往BAD治疗、纤维补充、排便时间及排便时阅读，均与BAD症状相关）计算比值比和95%置信区间。

结果

102名个体中，9人曾接受过痔疮治疗，4人接受手术治疗，5人接受药物治疗。20人目前有BAD症状，其中6人经常出现多种症状，意味着确诊为BAD，其中4人曾接受过痔疮治疗。过去一年有直肠出血症状的8人中，7人未寻求医疗评估。在所测试的关联中，仅发现女性与BAD症状之间存在统计学意义（比值比=4.6；95%置信区间=1.3 - 20.4）。

结论

在随机选取的人群中，痔疮治疗史和当前BAD症状非常普遍，80%有BAD症状的受试者未就BAD咨询过医生。一些先前认为与痔疮症状相关的因素，如肥胖和排便时间延长，与痔疮治疗史或当前BAD症状无明显关联。当前BAD症状的最佳预测因素是女性（比值比=4.6；95%置信区间=1.3 - 20.4）和既往痔疮治疗（比值比=3.9；95%置信区间=0.7 - 20）。
