摘要
背景:便秘为一常见临床问题,国内关于大学生人群便秘情况的大样本流行病学研究尚少。目的:调查武汉地区大学生便秘的流行病学特点并分析其影响因素。方法:采用问卷方式对华中科技大学3164名在校生进行调查。问卷内容包括社会人口统计资料、消化道症状[以功能性便秘(FC)罗马Ⅲ诊断标准中的内容为主]和生活压力问卷。便秘危险因素的分析先采用χ2检验进行单因素分析,有统计学意义者进入多因素Logistic回归分析。结果:问卷应答率为99.3%,有效率为92.7%。2912份有效问卷中男生2112名,女生800名,医学生811名,非医学生2101名。大学生FC总体患病率为10.4%,女生患病率显著高于男生(14.6%对8.8%,P<0.05)。男、女生中非医学生患病率均略高于医学生,但差异无统计学意义。便秘症状谱中以排便不尽感(70.6%)和排便费力(67.0%)最为多见。多因素Logistic回归分析显示生活压力、失眠、消化道疾病史为FC患病的危险因素,教育阶段为保护因素。结论:与国内一般人群相比,武汉地区大学生便秘患病率偏高,女生患病率高于男生。生活压力、教育阶段、失眠、消化道疾病史为便秘的主要影响因素。
Background: Constipation is a common bowel problem in clinical practice, however, large scale epidemiologic study on constipation in college students in China is seldom seen. Ahns: To investigate the epidemiologic characteristics and risk factors for constipation in college students in Wuhan. Methods: A questionnaire survey was conducted among 3164 students in Huazhong University of Science and Technology. Data on sociodemography, gastrointestinal symptoms, predominantly the symptoms of functional constipation (FC) described by Rome ~[ criteria, and life stress were collected by the questionnaire. Chi square test and multivariate logistic regression analysis were performed to evaluate the risk factors for constipation. Results: A total of 3143 students (99.3%) responded the questionnaire, of them, 2912 (92.7%) were eligible for analysis. The eligible respondents included 2112 males and 800 females; 811 were medical students and 2101 were non-medical students. The overall prevalence for FC in college students was 10.4%, and FC was more prevalent in females than in males ( 14.6% vs. 8.8%, P 〈 0.05 ). Non-medical students had a trend of higher FC prevalence than medical students in both male and female subcategories but with no significant differences. Feeling of incomplete evacuation (70.6%) and straining (60.7%) for bowel movement were the two most frequent symptoms. Multivariate logistic regression analysis revealed that life stress, insomnia and history of digestive diseases were risk factors for constipation and educational background was a protective factor. Conclusions : The prevalence of constipation in college students in Wuhan is substantially higher than that in general Chinese population, and the prevalence is higher in females than in males. Life stress, educational background, insomnia and history of digestive diseases are the major impact factors.
