To determine the bowel habits and its perceptions in the general population of Guangdong province.
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.
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 (OR = 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).
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.
确定广东省普通人群的排便习惯及其认知情况。
在广东省城乡地区分层的基础上，对18 - 80岁的常住居民进行随机整群抽样。问卷包括入选人群的特征及其排便习惯等项目。
共调查了4103名居民（男性1878名，女性2225名）。应答者的平均年龄为42.81±14.13岁。在4056名受试者中（缺失47名），2972名受试者（73.3%）报告每天排便，3951名受试者（97.4%）报告每周排便频率在3次至每天3次之间。270名受试者（6.6%）自述排便习惯异常。排便频率（比值比[OR]=2.03，95%可信区间[CI]：1.54 - 2.67）、粪便形态（OR = 2.75，95%CI：2.35 - 3.22）和排便费力（OR = 3.56，95%CI：2.49 - 5.11）与自述排便习惯异常显著相关。在3949名受试者中（缺失154名），根据罗马Ⅱ标准，644名（16.3%）被定义为排便习惯异常。自述排便习惯异常与罗马Ⅱ标准定义的异常之间的一致性较差（Kappa值 = 0.312）。
普通人群中正常排便频率定义为每周3次至每天3次似乎是合适的。自述排便习惯异常的患病率低于罗马Ⅱ标准定义的值，且这两种定义之间的一致性较差。
