Abstract

Abstract:

Objective To explore the potential categories and influencing factors of dietary behavioral adherence trajectories in young and middle-aged patients with type 2 diabetes mellitus. Methods A convenience sampling method was used to investigate 277 young and middle-aged patients with type 2 diabetes mellitus admitted to the Department of Endocrinology of a tertiary A hospital in Huai’an City，China，from September 2022 to March 2023. The baseline data were collected using a general information questionnaire，the Dietary Behavioral Compliance Scale for Patients with Type 2 Diabetes Mellitus，the Diabetes Self-Efficacy Scale，the Diabetes Knowledge Text，the Health Beliefs Questionnaire，and the Family APGAR Index Questionnaire. The baseline information was collected on the patients’ behavioral adherence trajectories a day prior to hospital discharge（T0），a week post-discharge（T1），a month post-discharge（T2），and 3 months post-discharge（T3） to assess the level of patients’ dietary behavioral adherence，using latent variable growth mixed models to identify trajectory categories，and univariate and multivariate logistic regression to analyze the influences on dietary adherence trajectories. Results A total of 3 trajectories of dietary behavior adherence in young and middle-aged patients with type 2 diabetes mellitus were identified，namely，low adherence-fluctuating group（49.8%），high adherence-slowly regressing group（31.4%），and medium adherence-continuously rising group（18.8%），and the results showed that age，literacy level，self-efficacy，health beliefs，and family caring were the factors influencing potential categories of dietary behavioral adherence for young and middle-aged patients with type 2 diabetes mellitus. Conclusion There is heterogeneity in the adherence trajectories of young and middle-aged patients with type 2 diabetes mellitus，and healthcare professionals can develop targeted interventions according to the influencing factors of the trajectory categories in order to improve their adherence.

摘要：

目的探讨中青年2型糖尿病患者饮食行为依从性变化轨迹的潜在类别及影响因素。方法采用便利抽样法，调查2022年9月—2023年3月在淮安市某三级甲等综合医院内分泌科住院的277例中青年2型糖尿病患者，采用一般资料调查表、2型糖尿病患者饮食行为依从性量表、糖尿病控制自我效能量表、糖尿病知识问卷、健康信念问卷、家庭关怀度指数问卷收集患者的基线资料，在患者出院前1 d（T0）、出院后1周（T1）、出院后1个月（T2）、出院后3个月（T3）评估患者的饮食行为依从性水平，采用潜变量增长混合模型识别轨迹类别，采用单因素及多元Logistic回归分析中青年2型糖尿病患者的饮食依从性轨迹的影响因素。结果共识别出3个中青年2型糖尿病患者饮食行为依从性变化轨迹类别，分别是低依从-波动起伏组（49.8%）、高依从-缓慢回落组（31.4%）、中依从-持续上升组（18.8%）；年龄、文化程度、自我效能、健康信念、家庭关怀度是中青年2型糖尿病患者饮食行为依从性潜在类别的影响因素。结论中青年2型糖尿病患者饮食行为依从性轨迹存在异质性，医护人员可根据轨迹类别的影响因素，制订针对性的干预措施，以提升其依从性水平。
