目的了解影响浙江省居民腹泻病发病的危险因素,为采取有针对性的腹泻病预防控制措施提供科学依据。方法采用分层多阶段随机整群抽样方法调查发现居民中的腹泻病例作为研究病例,选择与病例在同一自然村或小区、同性别、年龄相差小于±2岁、近两周内未发生腹泻的健康人作为研究对照,采用1∶2配比的病例对照研究方法,制定统一的调查表进行调查;分别采用单因素、多因素条件Logistic回归分析方法筛选腹泻病发病的关联因素。结果经分析进入模型差异有统计学意义(P<0.05)的变量为:基础疾病(P=0.007)、洗手习惯(P=0.025);其OR值分别为2.331、1.610。结论患有基础疾病、洗手习惯不好是浙江省居民腹泻病发病的危险因素。
Objective To understand the risk factors affecting the incidence of diarrhea in Zhejiang Province and provide scientific evidence for the prevention and control measures of diarrhea. Methods The stratified multistage randomized cluster sampling method was used to investigate the cases of diarrhea in residents. The cases were selected and the cases were in the same natural village or community, with the same sex and age difference of less than ± 2 years old. No diarrhea occurred in the past two weeks People as a research control, using a 1: 2 ratio of case-control study method, to develop a unified questionnaire for investigation; respectively, single factor, multivariate conditional Logistic regression analysis of screening for the incidence of diarrhea associated factors. Results The variables that were statistically significant (P <0.05) after entering into the model were as follows: basic disease (P = 0.007), habit of washing hands (P = 0.025), OR of 2.331 and 1.610 respectively. Conclusion The risk of diarrhea is a risk factor for diarrheal diseases in people with underlying diseases and poor hand-washing habits.
