目的:探讨青少年慢性胃炎的危险因素.方法:采取定群随机抽样的研究方法,首先对济南市5131例7—18岁在校中小学生进行问卷调查,经分检筛选出1500例反复出现上消化道症状的患者及3631名无症状健康者.从患者中随机抽取480例行胃镜检查及幽门螺杆菌(Hpylori)检测,确诊为慢性胃炎382例.健康者作为对照.随机抽取性别、年龄与患者相同的423名健康者,进行Hplori抗体检测作为Hpriori检测的对照.运用SPSS11.5统计软件,建立数据库,将每一被调查者的调查结果分别逐项输入数据库,最后运用相关及Logistic回归模型进行分析.结果:61项单因素相关分析中仅14项有显著性意义(P<0.05).进一步引入Logistic回归模型,9项有显著性意义,按相对危险度(OR)值高低排序,青少年慢性胃炎的危险因素及相应OR值为:家庭不和睦(6.621);不吃水果(4.000);胃黏膜快速尿素酶试验阳性(3.397);父母文化层次低(2.641);Cagh-IgG阳性(2.641);学习困难(2.536);非三口之家(2.222);有上消化道疾病家族史(1.917);不吃肉食(1.873).结论:青少年慢性胃炎的危险因素是以社会、心理因素为主的综合性因素,研究过热的Hpylori感染因素应客观认识,

Healthy controls as a random sample of gender, age and patients The same 423 healthy individuals were tested for Hplori antibody as a control for Hpriori detection.Using SPSS11.5 statistical software to establish a database, the survey results of each respondent were entered into the database one by one, and finally using the correlation and Logistic regression model (P <0.05) .By introducing Logistic regression model, nine of them have significant significance, according to the relative risk (OR) value of high and low rank, adolescent chronic The risk factors of gastritis and the corresponding OR values were: family disharmony (6.621), no fruit (4.000), gastric mucosa rapid urease test (3.397), low parental culture level (2.64 1); Cagh-IgG positive (2.641); learning difficulties (2.536); non-family of three (2.222); family history of upper gastrointestinal disease (1.917); no eating meat (1.873) .Conclusion: Risk factors are comprehensive factors based on social and psychological factors.
