摘要目的:分析浙江省≥50岁居民肺炎球菌疫苗接种率及其影响因素。方法:本研究为横断面研究。于2024年3—5月采用多阶段拦截调查方法，在浙江省35个县（市、区）175个社区卫生服务中心/卫生院拦截就诊、体检的10 500例居民进行问卷调查。调查内容包括基本情况、肺炎疾病史、慢性病患病情况、肺炎疫苗接种情况、医师推荐情况、接种/未接种原因、获取肺炎球菌疫苗信息途径等。根据基本情况、是否患慢性病、有无肺炎疾病史、有无医师推荐等进行分组，采用 χ 2检验比较不同组别间接种率的差异，采用二元logistic回归分析影响疫苗接种率的因素。 结果:10 500例调查对象中，接种肺炎球菌疫苗者1 724例（16.42%）。二元logistic回归分析结果显示，有医师推荐者的接种率高于无医师推荐者（26.25%比7.59%； OR=4.414，95% CI：3.851~5.059），享受免费政策者肺炎球菌疫苗的接种率高于未享受免费政策者（47.59%比5.18%； OR=12.527，95% CI：10.723~14.634）。肺炎球菌疫苗接种原因排名前三位的分别是免费政策（65.43%）、社区宣传（52.15%）、家人建议（42.34%）。调查对象获取肺炎球菌疫苗信息的途径排名前三位分别为电视（64.64%）、医师（59.81%）、家人（50.92%）。 结论:浙江省≥50岁居民肺炎球菌疫苗接种率较高，但还有待进一步提高，其接种率与免费接种政策、医师推荐等因素密切相关。

abstractsObjective:To analyze the pneumococcal vaccination rate and the influencing factors among residents aged≥50 in Zhejiang Province.Methods:This cross-sectional study was conducted between March and May 2024. A multi-stage intercept survey was used to intercept and survey 10 500 residents who visited or underwent physical examinations at 175 community health service centers/clinics in 35 counties (cities, districts) of Zhejiang Province. The questionnaire included basic demographic characteristics, history of pneumonia, chronic disease conditions, pneumococcal vaccination status, doctor recommendation, reasons for vaccination/non-vaccination, and channels for obtaining pneumococcal vaccine information. Participants were grouped based on demographic characteristics, chronic diseases conditions, history of pneumonia and doctor recommendations. The chi-square test was used to assess differences in vaccination rates among demographic groups while binary logistic regression models were used to identify factors affecting the vaccination rate.Results:Among the 10 500 surveyed participants, 1 724 (16.42%) had received pneumococcal vaccination. Binary logistic regression analysis revealed significantly higher vaccination rates among those who received a doctor recommendation compared to those without (26.25% vs 7.59%; OR=4.414, 95% CI: 3.851-5.059). Participants benefiting from the free vaccination policy showed higher vaccination rates than those who didn′t (47.59% vs 5.18%; OR=12.527, 95% CI: 10.723-14.634). The top three reasons for getting vaccinated against pneumonia were the free vaccination policy (65.43%), community promotion (52.15%), and family recommendations (42.34%). The top three sources through which respondents learned about the pneumococcal vaccine were television (64.64%), doctors (59.81%) and family members (50.92%). Conclusion:The pneumococcal vaccination rate among residents aged≥50 years in Zhejiang Province is relatively high but still needs further improvement, with vaccination rates closely associated with factors such as free vaccination policy and doctor recommendation.
