Objective: To investigate the trajectory changes of self-management in young and middle-aged patients with type 2 diabetes mellitus after discharge and analyze their latent classes and influencing factors. Methods: Using a longitudinal study design, 180 young and middle-aged patients with type 2 diabetes mellitus treated in our hospital from June 2023 to June 2024 were included as study subjects. Follow-up surveys were conducted on patients' self-management status within one year after discharge. Latent Growth Mixture Model(LGMM) was used to analyze self-management trajectory changes and classes. Based on collected clinical data, Logistic regression analysis was used to analyze influencing factors of latent classes. Results: Among 180 patients, 168 patients ultimately completed the study. Self-management scores of young and middle-aged patients with type 2 diabetes mellitus showed a declining trend with prolonged time after discharge. Through LGMM analysis, three latent classes were finally selected and retained as the optimal model: high-level rising group(40 cases, 23.81%), medium-level maintaining group(59 cases, 35.12%), and low-level declining group(69 cases, 41.07%). Significant differences were found among the three trajectory groups in age, education level, monthly family income per capita, comorbidities, living arrangements, disease knowledge scores, and family care index(all P<0.05). Logistic regression analysis showed that, with the low-level declining group as reference, age, disease knowledge scores, monthly family income per capita, comorbidities, and family care index were influencing factors for medium-level maintenance; with the medium-level maintaining group as reference, disease knowledge scores and monthly family income per capita were influencing factors for high-level rising(P<0.05). Conclusion: Self-management behavior in young and middle-aged patients with type 2 diabetes mellitus shows a declining trend with prolonged time outside the hospital after discharge, presenting three trajectory patterns: high-level rising, medium-level maintaining, and low-level declining. Among these, age, disease knowledge scores, monthly family income per capita, comorbidities, and family care index are influencing factors for medium-level maintenance, while disease knowledge scores and monthly family income per capita are influencing factors for high-level rising. Targeted measures can be developed clinically based on the above factors to improve patients' self-management behavior. |
