Factors affecting diabetes knowledge in Type 2 diabetic veterans

Area of Science:

• Endocrinology
• Geriatrics
• Public Health

Background:

• Type 2 diabetes is a prevalent chronic condition requiring significant self-management.
• Veterans represent a unique population with specific health challenges and needs.
• Adequate diabetes knowledge is crucial for effective self-care and disease management.

Purpose of the Study:

• To identify clinical, psychological, and social factors influencing diabetes knowledge in veterans with Type 2 diabetes.
• To develop a predictive model for identifying veterans with limited diabetes knowledge.

Main Methods:

• An observational study involving 284 insulin-treated veterans with stable Type 2 diabetes.
• Utilized validated instruments including the University of Michigan Diabetes Research and Training Centre Knowledge Test, Diabetes Care Profile, Mini-Mental State Examination, Geriatric Depression Scale, and Diabetes Family Behaviour Checklist.
• Employed stepwise multiple linear regression for multivariate analysis to determine independent predictors of diabetes knowledge.

Main Results:

• Veterans demonstrated poor performance on the diabetes knowledge test (mean 64.9% correct).
• Multivariate analysis identified age, education level, duration of diabetes treatment, cognitive function, sex, and depression severity as independent determinants of knowledge scores.
• A predictive model derived from demographic and psychosocial variables showed strong correlation in a validation set (r=0.537, p<0.001).

Conclusions:

• Stable, insulin-treated veterans exhibit significant deficits in diabetes knowledge, potentially compromising self-care.
• A multivariate model incorporating demographic and psychosocial factors can effectively identify individuals with limited diabetes knowledge.
• This model can guide the assessment of barriers and the personalization of diabetes education for veterans.
