Risk factors for mortality among people with diabetes in Spain: The DIMORTES study

Area of Science:

• Public Health
• Epidemiology
• Internal Medicine

Background:

• Diabetes mellitus (DM) is a prevalent chronic condition with rising global incidence.
• Understanding mortality factors in DM is critical for public health interventions.

Purpose of the Study:

• To analyze all-cause mortality and associated factors in individuals with diabetes mellitus (DM) in Spain.
• To identify key risk factors contributing to mortality in the Spanish DM population.

Main Methods:

• A population-based retrospective study utilizing Spanish National Health Survey and national death register data (2011/2012).
• Six-year follow-up period analyzing sociodemographic, health, service use, and lifestyle factors.
• Statistical analysis focused on all-cause mortality in individuals with and without DM.

Main Results:

• 12.0% of respondents over 40 had DM; 19.7% cumulative incidence of all-cause mortality over follow-up.
• Key mortality predictors in DM patients included COPD, recent hospital admission, depression, and smoking.
• Time-dependent association observed between mortality and history of acute myocardial infarction.

Conclusions:

• Significant associations exist between mortality in DM patients and chronic respiratory disease, depressive disorder, recent hospital admission, and smoking.
• Enhanced detection and management of these comorbidities are essential for mitigating mortality risk in diabetes.
• Public health strategies should prioritize addressing these identified risk factors to improve outcomes for individuals with DM.
