1、北京上海胃食管反流症状的流行病学调查【摘要】目的了解北京、上海成人胃食管反流病(GERD)和反流性食管炎(RE)，在1996年79月调查时一年内的患病率及其相关性疾病和危急因素等。方法对两市1870岁城乡常住人口5 000例，进行整群、分层、随机抽样的问卷调查。以反酸、烧心、反食症状程度和频度的积分(Sc,最高18分)作为反流的指标，Sc6表明存在症状性反流(GER)；再抽取一部分反流阳性病人和比照者用胃镜和24小时pH监测作精查，依据精查的正确率对普查结果校正后测算出患病率。结果(1) 共4 992例完成了筛查，人群中每日有烧心者占2.5%；Sc6者448例占8.97%，男女之比为11.1；
2、精查正确率为64%，据此推想GERD的患病率为5.77%，RE为1.92%。(2) 分层分析显示，有反流症状者北京(10.19%)多于上海(7.76%)，北京的男性病人、体力劳动者及农村的患病率均高于上海；此外，40岁以上的患病率增多。(3) 反流组伴发口咽喉病患、哮喘和支气管炎的频率比非病人人群明显为高。结论调查结果显示，GERD为多发病，但我国南北方的患病率有差别。GERD和RE的比值为31。年龄(OR 1.01)、饱食(OR 1.99)、油腻食物(OR 6.56)、劳累(OR 2.35)、精神心情(OR 2.22)、妊娠(OR 6.80)、排便困难(OR 1.65)等因素和反流有亲密关系

Methods5 000 residences of the two cities, age between 18-7
5、0 were studied through questionaire. Study was done by clustering sampling from city, surburban and rural areas using simple random sampling. Symptom scores (Sc) of the intensity and frequency of heartburn, acid reflux and regurgitation within one year at the time of study were taken as indices of a

A case control study was also performed in some subjects from the survey to confirm the diagnosis of GERD and RE using gastroscopy and 24h pH monitoring. An estimation of the prevalence of GERD and RE was made on the basis

Results(1) 4 992 subjects completed the survey, 2.5% of the people had heartburn once a day, 448 people accounted for 8.97% of the population screened had symptomatic GER (Sc6), and male to female ratio was 11.1.

(2) Stratified analysis indicated that the prevalence of symptomatic GER in Beijing (10.19%) was higher than that in Shanghai (7.76%), and there was also a higher prevalence of GER in male, in laboring people and in people of rural areas in Beijing as compared with Sh

(3) Logistic analysis indicated that GER had a close relatioship with dental, pharnyngo-laryngeal disorders and respiratory diseases, such as asthma and bronchitis, etc. ConclusionsGERD is different in the northern and southern area of China.

11、disease,GERD)是指过多的胃、十二指肠内容物反流入食管，引起烧心、反酸、反食等，甚至有食管粘膜的病理性损害反流性食管炎(reflux esophagitis,RE)。但GERD病人不肯定均伴有RE。本症还可引起口咽、喉、气道等食管外的组织损害。关于人群中症状性胃食管反流(GER)、GERD和RE的患病率，西方国家报道，人群中约7%15%可有胃食管反流症状1。北京协和医院1986年对3 000例接受胃镜检查病人的调查表明，RE占5.8%2；台湾一所医院对2 044例病人作胃镜检查，RE为5%3。但对GERD在人群中患病率的随机调查在国内缺乏系统性的资料。本探讨的目的：(1) 了解北京、
12、上海两市成人症状性GER的发生状况及GERD和RE的患病率，(2) 探讨GER和呼吸道、口咽部疾患的关系，(3) 了解与GERD发病有关的危急因素等。调查方法一、筛查1996年79月。采纳整群、分层和单纯随机抽样的方法，对北京及上海市(简称两市)1870岁的常住城乡居民各2 500例进行问卷调查。依据市统计局供应的资料，按人口比例设计，对两市城区、近郊、远郊区、县的办事处到居委会和村委会，逐级进行整群、随机抽签抽样。对抽到的居委会符合年龄条件的居民，每户每人，由经过培训的调查员(多数为医师，少数为医学生和护士)在居(村)委会人员的陪伴下，分别入户进行问卷调查。问卷内容涉及反流症状、发生频度、伴
13、随症状及疾病、职业、饮食习惯、生活方式、既往病史和危急因素等94个项目。样本覆盖人群：北京市常住人口为1 100万、上海市为1 300万，1870岁的人占两市常住人口的73%；样本量5 000例，覆盖两市各年龄组人群为：500073%=6 844例。调查结束后，选择部分被调查者的问卷由另人复核，正确率为95.6%。二、症状评分及统计调查反酸、反食、烧心、胸骨后痛、咽部异物感、腹胀等18个症状的发生状况。以烧心、反酸、反食作为评分症状：无症状为0分，症状轻为1分，症状中等为2分，症状重为3分。另依据频变，如每月有症状为1分，每周为2分，每日为3分。依据症状程度及频度，积分之和为总分(Sc)，最高
14、18分。将调查资料输入电脑，分档统计，结果见表1。以上Sc6共448例，占总调查人数的8.97%，其中Sc10共138例，占2.76%；Sc6的人占91.05%。我们以Sc6作为症状性GER的诊断标准，将Sc6设定为非反流(或称非病人)人群组，作为比照。以这段时间内有反流症状人群的检出率代表患病率。表1调查人群症状积分(Sc)Sc02569101213人数3 63985131010236%74.0017.056.212.040.72对症状性GER人群的患病率、不同年龄和职业的人群患病率、北京和上海之间及脑力、体力劳动者患病率的差别以及不同饮食、生活方式与患病率之间的关系等进行了调查。全部资料均
