To investigate the present situation of elderly constipation in urban and rural areas of the Beijing region.
A total of 1942 cases (≥ 60 years) were selected in the Beijing region for investigation. Constipation-related data collection was carried out via hierarchical status, segmentation, and random cluster sampling. Patient data concerning constipation-related demographic indicators, education level, occupation, economic status, and history of gastrointestinal disease was obtained via questionnaires and surveys. Constipation was defined according to the Rome III criteria, with the following constipation judgment indicators: defecation less than 3 times per week, stool weight less than 35 g/d, dry and hard stool, and difficulty in defecating during more than 25% of evacuation attempts.
Of the 1942 cases, 634 were diagnosed with constipation, and the total prevalence rate was 32.6%, which increased with age. There was a statistically insignificantly higher prevalence of constipation in females (compared to males) and urban areas (compared to rural areas). There was a statistically insignificantly higher prevalence in the illiterate group compared to the literacy group. Those engaged in mental work suffered from statistically significantly higher constipation prevalence than those engaged in physical labor. A total of 1847 cases did not suffer from gastritis, of which 595 cases were constipated; although the prevalence rate was 32.2%, showing a higher incidence of constipation in patients with gastritis, no significant statistical difference between the two groups was found. A total of 59 cases with a past history of biliary tract disease were found, of which 26 had constipation; constipation prevalence was 44.1% (far higher than other groups), which was a statistically significant difference.
The prevalence of elderly constipation in the Beijing region closely resembles Western countries, and is significantly affected by region, age, and past history of other related illnesses.
调查北京地区城乡老年人便秘的现状。
在北京地区选取1942例（≥60岁）进行调查。通过分层、分段、随机整群抽样进行便秘相关数据收集。通过问卷调查获取便秘相关的人口统计学指标、教育程度、职业、经济状况及胃肠道疾病史等患者资料。根据罗马Ⅲ标准定义便秘，便秘判断指标如下：每周排便少于3次、粪便重量少于35g/天、大便干结、超过25%的排便尝试有排便困难。
1942例中，634例被诊断为便秘，总患病率为32.6%，患病率随年龄增加。女性（与男性相比）和城市地区（与农村地区相比）便秘患病率略高，但无统计学意义。文盲组便秘患病率略高于识字组，但无统计学意义。从事脑力劳动的人群便秘患病率显著高于从事体力劳动的人群。共有1847例无胃炎，其中595例便秘；患病率为32.2%，胃炎患者便秘发病率较高，但两组间无显著统计学差异。共有59例有胆道疾病史，其中26例便秘；便秘患病率为44.1%（远高于其他组），有统计学显著差异。
北京地区老年便秘患病率与西方国家相近，且受地区、年龄及其他相关疾病史影响显著。
