Abstract: Background　Chronic diseases have become a significant public health issue in China. Due to the prolonged course and difficulty in achieving a cure，it is essential to promote full-life-cycle integrated medical and preventive care for prevention and treatment of chronic diseases. However，medical services and public health services in China are separatedand there is still a gap in the supply of integrated medical and preventive care. Grassroots doctors are key providers of such services，and their behavior directly impacts the quality of integrated medical and preventive care. Therefore，it is crucial to explore the behavioral intention of grassroots doctors in providing integrated medical and preventive care for chronic diseases. Objective　This study investigates the current status and influencing factors of the behavioral intention of integrated medical and preventive care provided by grassroots doctors for patients with chronic diseases in Shandong Province. The aim of the study is to offer insights and guidance for improving the quality of integrated medical and preventive care at the grassroots level. Methods　A total of 481 grassroots doctors were collected through multi-stage stratified cluster random sampling in Shandong Province. A questionnaire survey was conducted to investigate grassroots doctors' behavioral intention to integrate medical and preventive care，and the influencing factors were analyzed using univariate analysis and binomial logistic regression. The questionnaire of this study is entitled "Questionnaire on the behavioral intention of integrated medical and preventive care provided by grassroots doctors for patients with chronic diseases" and its content was modified after expert consultation. The questionnaire mainly includes four parts：questionnaire on general situation，questionnaire on the awareness of integrated medical and preventive care， questionnaire on the assessment of the environment of integrated medical and preventive care in grassroots medical institutions， and questionnaire on the behavioral intention of integrated medical and preventive care provided by grassroots doctors. Results　83.16% of grassroots doctors had a high level of behavioral intention to provide integrated medical and preventive care. Grassroots doctors who were female（OR=2.149），had junior college diploma（OR=2.736），had a higher level of awareness of integrated medical and preventive care（OR=3.549），and were employed in the organizations with better environment（OR=8.264）had a stronger behavioral intention to provide integrated medical and preventive care（P<0.05）. Conclusion　Currently，grassroots doctors show strong behavioral intention to provide integrated medical and preventive care for patients with chronic diseases. However， it is still necessary to establish a sound incentivization mechanism. A variety of promotional strategies should be utilized to further raise awareness among grassroots doctors. Additionally，dedicated funding should be well allocated to optimize the healthcare environment at the grassroots level. It is also essential to develop well-defined policy documents and service guidelines for integrated medical and preventive care. Furthermore，targeted training on integrated medical and preventive care should be implemented for grassroots doctors with specific characteristics.

摘要： 背景　慢性病已成为我国重要的公共卫生问题。因其病程长且难治愈，推行全周期的医防融合服务是防治关键。但当前我国医疗服务与公共卫生服务割裂，医防融合服务供给仍存在缺口。基层医生是医防融合服务的重要提供者，其在提供医防融合服务过程中的行为直接影响到患者接受的医疗卫生服务质量。因此，探究基层医生慢性病医防融合服务行为意向至关重要。目的　调查山东省基层医生慢性病医防融合服务行为意向现状，探究其影响因素，为进一步推动基层医防融合工作的开展提供依据。方法　本研究于 2023 年 8 月在山东省开展调查，采用多阶段分层随机抽样，按照地理位置和经济发展水平，在山东省的东、中、西部地区各选择烟台市、潍坊市以及聊城市，在每个地市随机选择 1 个区和 1 个县 / 县级市作为样本地区，选取 481 名基层医生进行调查。研究者自制《基层医生慢性病医防融合服务提供调查问卷》，经专家咨询后修改完善问卷内容，主要包括四部分：一般情况调查表、医防融合服务认知问卷、基层医疗机构医防融合服务环境评价问卷、基层医生医防融合服务提供行为意向问卷。采用 χ2 检验与二元 Logistic 回归模型分析其影响因素。结果　83.16% 的基层医生的慢性病医防融合服务提供行为意向处于高水平。二元 Logistic 回归模型分析结果显示，女性（OR=2.149）、大专学历（OR=2.736）、医防融合认知水平较高（OR=3.549）、所就职医疗卫生机构环境较好（OR=8.264）的基层医生提供慢性病医防融合服务的行为意向更强（P<0.05）。结论　当前基层医生慢性病医防融合服务行为意向较强，但仍应建立完善医防融合考核与激励机制，制定合理的医防融合工作政策文件与服务指南，通过多种方式提升基层医生的认知，设立医防融合专项资金优化基层医疗卫生机构环境，针对特定人群增加医防融合培训次数。
