目的研究成人接种乙肝疫苗影响因素。方法在上海市闵行区随机抽取18~50岁成年居民613人,进行乙肝疫苗接种影响因素调查,用非条件Logistic回归分析影响因素。结果613人中,接种过乙肝疫苗153人,接种率25.37%,其中父母带去接种27人,学校或单位组织接种59人,自己主动接种67人;影响主动接种乙肝疫苗的因素主要是年龄、家庭人均月收入、周围有乙肝病人、对不用安全套性交可传播乙肝、尚无治愈乙肝的特效药、我国居民乙肝病原携带率高等有正确认识(P<0.05);多因素分析表明,家庭人均月收入高,认为同桌吃饭(OR=1.97)、共用办公设备可传染乙肝(OR=8.67),正确认识尚无治愈乙肝的特效药者(OR=2.27)易主动接种乙肝疫苗。愿意接种乙肝疫苗的影响因素主要是文化程度,对乙肝是肝癌发病的重要病因、我国居民乙肝病原携带率高正确认识与否(P<0.05)。结论对乙肝相关知识了解不够、经济、成人接种服务不够便利等是闵行区成人乙肝疫苗主动接种的主要影响因素。 Objective To study the influencing factors of hepatitis B vaccine in adults. Methods A total of 613 adult residents aged 18-50 years were randomly selected from Minhang District in Shanghai to investigate the influencing factors of hepatitis B vaccination and the influencing factors were analyzed by non-conditional Logistic regression. Results Among 613 people, 153 were inoculated with hepatitis B vaccine and the inoculation rate was 25.37%. Among them, 27 were brought in by parents, 59 were inoculated by schools or units and 67 were vaccinated voluntarily. Influencing factors of active hepatitis B vaccination were mainly age, Family per capita monthly income, surrounded by hepatitis B patients, without condom can be transmitted sexual intercourse hepatitis B, hepatitis C still no cure for the disease, our country residents with high prevalence of hepatitis B pathogens have a correct understanding (P <0.05); multivariate analysis showed that the average monthly household (OR = 1.97). The shared office equipment could infect hepatitis B (OR = 8.67). The correct understanding of those who did not cure hepatitis B (OR = 2.27) was more likely to take the initiative to vaccinate against hepatitis B vaccine. Willingness to inoculate hepatitis B vaccine is mainly affected by the degree of education, the incidence of hepatitis B is an important cause of liver cancer, hepatitis B pathogens in our country residents with high awareness of correctly (P <0.05). Conclusions Insufficient knowledge about hepatitis B, economy and inadequate access to adult vaccination services are the main influencing factors for active hepatitis B vaccination in Minhang District.
