Objective

To investigate the status and influencing factors of fear of hypoglycemia (FoH) in elderly patients with type 2 diabetes mellitus (T2DM), providing evidence for improving glycemic management and psychological health.

Methods

From March 2022 to January 2023, 302 elderly T2DM patients from three tertiary hospitals in Chengdu were assessed using general information questionnaires, Hypoglycemia Fear Survey-Worry Scale, Social Support Rating Scale, and Connor-Davidson Resilience Scale.

Results

The mean FoH score was 33.009±11.243, indicating high overall fear levels. Random forest model screening (optimal λ=0.77925) identified seven key factors in descending importance: psychological resilience, social support, subjective support, objective support, support utilization, hypoglycemia type, and education level. Multiple linear regression showed psychological resilience (β=-0.315, 95%CI: -0.455 to -0.246), subjective support (β=-0.260, 95%CI: -0.845 to -0.374), objective support (β=-0.176, 95%CI:-0.895 to -0.256), and support utilization (β=-0.145, 95%CI:-1.327 to -0.226) negatively influenced FoH, while hypoglycemia type (β=0.314, 95%CI: 2.227 to 3.873) and frequency (β=0.296,95%CI: 2.632 to 4.719) were positive contributors.

Conclusion

Elderly T2DM patients exhibit high FoH levels influenced by multiple factors. Healthcare providers should enhance psychological resilience and social support, with particular attention to patients experiencing severe or frequent hypoglycemic episodes.
