摘　　要：目的 探讨广东省社区人群排便习惯的状况,以及调查对象自己认为的排便习惯异常与罗马Ⅱ定义中的排便习惯异常的一致性.方法 采用整群、分层、随机抽样的方法在广东省内对广州市、惠州市及农村三地区的常住人口中18～80岁的居民进行面访式问卷调查,调查内容涉及被涮查者的人口学资料及排便习惯等.结果 实际调查4103名;男性1878名,女性2225名;平均年龄（42.81±14.13）岁.在回答排便频率的4056名（缺失47名）中,每日排便1次者为2972名（73.3%）.排便次数在3次/d至3次/周的为3951名（97.4%）.270名（6.6%）自诉排便习惯异常者,排便频率（OR=2.03.95%CI：1.54～2.67）、大便性状（OR=2.75,95% CI：2.35～3.22）及排便费力（OR=3.56,95% CI：2.49～5.11）与其自诉的排便习惯异常密切相关.在3949名（缺失154名）中,按定义界定排便习惯异常者为644名（16.3%）.被调查人群自己认为排便习惯异常与按定义界定排便习惯异常两者的一致性较差（Kappa=0.312）.结论 将人群中正常排便频率界定为3次/d至3次/周是合适的,调查人群中自己认为排便习惯异常的比例明显低于罗马Ⅱ标准实际检出的比例,两者的一致性较差.Objective To determine the bowel habits and its perceptions in the general population of Guangdong province. Methods Random clustered sampling involving permanent inhabitants aged 18-80 year was carried out under stratification of urban and suburban areas in Guangdong province. Questionnaire included the items on the characteristics of people being selected and their bowel habits. Results A total of 4103 residents （male 1878, female 2225） were investigated. Mean age among the responders was 42.81 ±14.13 year. Among 4056 subjects （missing = 47）, 2972 subjects （73.3 % ） reported daily defecation, and 3951 subjects （97.4%） reported stool frequency between 3 times per week and three times per day. Two hundred and seventy subjects （6.6%） reported abnormal bowel habits by themselves. The stool frequency （OR=2.03, 95% CI： 1.54-2.67） , forms of stool （0R=2.75, 95% CI： 2.35-3.22） and straining （OR=3.56, 95% CI： 2.49-5.11） were significantly associated with self-reported abnormal bowel habits. Among 3949 subjects （missing= 154）, 644 （16.3%） were defined as having abnormal bowel habits according to Rome Ⅱ criteria. There was poor agreement between self-reported abnormal bowel habits and that defined by Rome Ⅱ criteria （Kappa：0.312）. Conclusion It seemed to be appropriate that the normal stool frequency was defined as bowel movements between 3 times per week and three times per day in the general population. The prevalence of self-reported abnormal bowel habits was lower than that defined by Rome Ⅱ criteria and the agreement between these two definitions was poor.
