调查北京老年人饮食与便秘患病率之间的相关性。
在北京地区选取2776名（≥60岁）老年人进行调查。采用分层、分段、随机整群抽样的方法收集便秘及饮食习惯相关数据。调查内容包括与便秘相关的人口统计学指标和饮食习惯。通过上门问卷调查，了解每日主食摄入量、鱼、蛋、水果和蔬菜的食用频率。便秘根据《中国慢性便秘诊断和治疗指南（2013年版）》进行定义，便秘判断指标如下：排便频率降低、粪便干结、排便困难。
北京地区老年人便秘患病率为13%。便秘患病率与年龄呈正相关，与主食、鱼类和膳食纤维（水果和蔬菜）摄入量呈负相关。这些差异均具有统计学意义。
北京地区老年便秘患病率与饮食习惯密切相关，增加主食摄入量、食用鱼类和高膳食纤维（水果和蔬菜）摄入可显著降低便秘患病率。
