BACKGROUND/AIMS: It is essential that clinicians have an understanding of patients' perceptions of constipation as well as constipation mis-perception (CM), which can be defined as failure to recognize the six constipation symptoms (infrequency, straining, hard stool, incomplete evacuation, anorectal obstruction or manual maneuver). The aims of our study were to identify the prevalence of CM and its association with demographics and clinical features.
This nationwide survey included 625 self-reported constipated subjects (431 females; mean age, 41.2 years) among random participants in the National Health Screening Program. The prevalence of CM for each constipation symptom was estimated, and the participants were classified into nil (0), low (1-2), mid (3-4) and high (5-6) level CM subgroups according to the number of misperceived symptoms.
The highest rate of CM was observed for manual maneuver (48.3%), followed by anorectal obstruction (38.4%), stool infrequency (34.6%), incomplete evacuation (32.2%), hard stool (27.2%) and straining (25.4%). Among the nil (n = 153), low (n = 242), mid (n = 144) and high level (n = 86) subgroups, there were significant differences in the proportions of males (18.3%, 34.3%, 39.6% and 30.2%; P = 0.001, respectively), never-married status (25.7%, 38.2%, 36.8% and 45.9%; P = 0.030, respectively) and those who did not receive treatment for constipation (41.8%, 47.5%, 58.3% and 66.3%; P < 0.001, respectively). There was a significant linear trend of increasing degree of CM with decreasing symptoms experienced (P < 0.001).
CM is significantly associated with gender, marital status, treatment utilization and the range of constipation symptoms experienced.
背景/目的：临床医生了解患者对便秘的感知以及便秘误解（CM）至关重要，CM 可定义为未能识别便秘的六个症状（频率低、用力排便、硬便、不完全排空、肛肠梗阻或手动操作）。我们研究的目的是确定 CM 的流行率及其与人口统计学和临床特征的关系。
这项全国性调查包括全国健康筛查计划中随机参与者中的 625 名自报便秘患者（431 名女性；平均年龄 41.2 岁）。估计了每个便秘症状的 CM 流行率，并根据误解症状的数量将参与者分为无（0）、低（1-2）、中（3-4）和高（5-6）CM 亚组。
CM 发生率最高的是手动操作（48.3%），其次是肛肠梗阻（38.4%）、排便频率低（34.6%）、不完全排空（32.2%）、硬便（27.2%）和用力排便（25.4%）。在无（n=153）、低（n=242）、中（n=144）和高（n=86）亚组中，男性比例（18.3%、34.3%、39.6%和 30.2%；P=0.001）、未婚状态（25.7%、38.2%、36.8%和 45.9%；P=0.030）和未接受便秘治疗的比例（41.8%、47.5%、58.3%和 66.3%；P<0.001）存在显著差异。CM 程度与经历的症状数量呈显著负相关（P<0.001）。
CM 与性别、婚姻状况、治疗利用以及便秘症状范围显著相关。
