360例腹泻型肠易激综合征主要证候分布与不同因素关系的研究

Study on Relationship between the Main Symptoms Distribution and Different Factors of 360 Cases of IBS-D

目的研究腹泻型肠易激综合征(IBS-D)流行病学特点以及主要证候与不同因素的关系。方法采用临床流行病学调查方法,收集患者相关资料,以探讨IBS-D的主要证候特点及其与不同因素的关系。结果IBS-D患者年龄集中在30～49岁之间;就诊人群的特殊嗜好依次为饮酒、吸烟、嗜辛辣、嗜咖啡等;情志不畅、精神紧张和饮食不节是其主要诱因;肝郁脾虚证所占比率最高(44.7%),不同年龄段、不同性别、不同职业和不同文化程度的证候分布无明显差异。结论IBS-D患者实际就诊人数低于实际患病人数,精神心理因素是其重要内因,而饮食因素可能是其启动的重要外因;不同因素对证候分布无影响。
