Heterogeneity of Ego Depletion and Its Relationship With Health Promotion Behavior Among Older Adults With Type 2 Diabetes Mellitus: Latent Profile Analysis

Purpose: To identify latent profiles of ego depletion among older adults with type 2 diabetes mellitus (T2DM), and analyze how these profiles relate to health promotion behaviors. Method: A cross-sectional study surveyed 220 older adults with T2DM on ego depletion and health promotion behaviors. Latent profile analysis identified distinct profiles of ego depletion, and multinomial logistic regression explored their links to health promotion behaviors. Results: Latent profile analysis revealed three distinct profiles: high cognitive depletion, high behavioral depletion, and high emotional depletion. The high behavioral depletion profile was associated with fewer complications, more hypoglycemia, better stress management, greater enjoyment of life, and increased health responsibility. The high emotional depletion profile had lower levels of physical activity, reduced risk reduction behaviors, poorer stress management, and less adherence to a healthy diet. Conclusion: Tailored interventions addressing ego depletion are crucial for improving health promotion behaviors in this population.
