Abstract: Background　Effective utilization of chronic illness resources can help individuals with prediabetes adhere to healthy behavior changes and improve their health status. However，the current state of chronic illness resource utilization in this population remains unclear and requires further investigation. Objective　To explore the latent categories of chronic illness resource utilization among individuals with prediabetes and their relationship with health-promoting behaviors. Methods　A consecutive sampling method was used to select individuals with prediabetes who underwent physical examinations at two community health service centers in Nanjing from March to July 2024. Data were collected using a general information questionnaire，the Chronic Illness Resource Survey（CIRS），and the Health-Promoting Lifestyle Profile Ⅱ（HPLP-Ⅱ）. Latent profile analysis（LPA） was performed to classify chronic illness resource utilization，and hierarchical regression analysis was used to examine the relationship between resource utilization categories and health-promoting behaviors. Results　A total of 270 questionnaires were collected，with 263 valid questionnaires，yielding a 97.4% valid response rate.The mean score for chronic disease resource utilization in the prediabetes population was（49.1±8.7），and the mean score for health-promoting behaviors was（131.1±17.0）. Chronic illness resource utilization was categorized into three latent groups：low-resource utilization（basic dependence type）（136 individuals，51.7%），moderate-resource utilization（limited support type）（105 individuals，39.9%），and high-resource utilization（multiple support type）（22 individuals，8.3%）. Hierarchical regression analysis showed that，after controlling for confounding factors，the category of chronic illness resource utilization was a significant predictor of health-promoting behaviors in individuals with prediabetes（P<0.001），explaining 13.8% of the variance. Conclusion　There are three latent categories of chronic illness resource utilization in individuals with prediabetes，and these categories significantly influence health-promoting behaviors. In the future，healthcare providers can implement targeted interventions based on the categories of chronic illness resource utilization to improve health-promoting behaviors and enhance health outcomes.

摘要： 背景　慢性病资源的有效利用可以促使糖尿病前期人群坚持健康行为改变，提升健康状态，然而目前糖尿病前期人群慢性病资源利用情况尚未明晰，有待进一步探究。目的　探讨糖尿病前期人群慢性病资源利用的潜在类别及其与健康促进行为的关系。方法　采用连续性抽样的方法，选取2024年3—7月在南京市两家社区卫生服务中心体检的糖尿病前期人群作为研究对象。采用一般资料调查表、慢性病资源调查问卷（CIRS）、健康促进生活方式量表Ⅱ（HPLP-Ⅱ）进行资料收集。采用潜在剖面分析对糖尿病前期人群慢性病资源利用情况进行分类，采用分层回归分析探讨资源利用类别与健康促进行为的关系。结果　共回收问卷270份，有效问卷263份，问卷有效回收率为97.4%。糖尿病前期人群平均CIRS得分为（49.1±8.7）分，平均HPLP-Ⅱ得分为（131.1±17.0）分。糖尿病前期人群慢性病资源利用可分为低资源利用-基础依赖型［136名（51.7%）］，中资源利用-有限支持型［105名（39.9%）］，高资源利用-多元支持型［22名（8.3%）］3种潜在类别。分层回归分析结果显示，控制混杂因素后，慢性病资源利用类别是糖尿病前期人群健康促进行为的影响因素（P<0.001），可解释13.8%的变异量。结论　糖尿病前期人群慢性病资源利用存在3种潜在类别，慢性病资源利用类别是其健康促进行为的影响因素。未来医护人员可根据慢性病资源利用类别采取针对性干预措施，提高健康促进行为水平，改善健康结局。
