Objective To survey the current status and distribution of constipation in Chinese old population. Methods The 8 252 elderly, aged ≥60 years,in the urban and rural areas of 6 cites were investigated using a cluster random sampling methods. Results The rude prevalence of constipation was 11.5%. The prevaleme increased with ageing 〔8.7%,9.6%,11.7%,15.3%,17.2% and 19.5% respectively in the age groups of 60-,65-,70-,75-,80-,85- years old 〕.The rude prevalence was higher in north of China (17.5%) than that in south of China. It was relatively higher in female (9.98%) than that in male (8.39%) and different by house worker (15.6%), managers (13.4%), workers and business (10.1%) and other profession (8.3%,P＜0.01).Logistic regression analysis also showed the rude prevalence was related with gender, ageing and area (P＜0.01). Conclusions The rude constipation prevalence of Chinese elderly population increased with ageing. Beside the ageing factor, it was also related with gender, area and profession.%目的探讨老年人便秘患病现状和分布特点。方法采用多级、整群抽样的方法，对6个城市8 252名≥60岁的常住老年人进行横断面流行病学调查。结果老年人便秘总患病率为11.5%，随着年龄的增长患病率增加，60～、65～、70～、75～、80～和85+年龄组的患病率分别为8.7%、9.6%、11.7%、15.3%、17.2%、19.5%(P<0.01)；老年人便秘城市患病率为10.9%,农村为12.3%,农村高于城市(P＜0.01)，且地区差异明显(P＜0.01)，北方地区患病率较高，为17.5%；老年人便秘患病率存在职业差别(P＜0.01)，从事家务、行政管理、科教文卫职业者患病率较高，分别为15.6%、13.4%和12.7%，工人和商企人员的患病率较低，均为10.1%。多因素Logistic回归分析表明，性别、年龄、城乡和地区与便秘患病率密切相关。结论随年龄增长老年人便秘的患病率增加，北方高于南方，女性高于男性，除年龄因素外，老年人便秘还可能与气候、膳食结构、体力活动量等因素有关。
