A claims data-based comparison of comorbidity in individuals with and without dementia
Bauer K, Schwarzkopf L, Graessel E, Holle R.. BMC geriatrics, 2014-01-28
Topic: Risk, prevention and care in population studies
Background Multimorbidity is common in advanced age, and is usually associated with negative - yet to some extent preventable - health outcomes. Corresponding prevalence rates were calculated, and the association between a distinct condition and dementia was evaluated via logistic regression in the overall sample as well as in analyses stratified by gender and living environment. Results Individuals with dementia were more likely to be diagnosed with 15 comorbidity complexes, including Parkinson's, stroke, diabetes, atherosclerosis (supposed dementia risk factors) or fluids and electrolyte disorders, insomnia, incontinence, pneumonia, fractures and injuries (supposed sequelae).

Key findings
- Background Multimorbidity is common in advanced age, and is usually associated with negative - yet to some extent preventable - health outcomes.
- Corresponding prevalence rates were calculated, and the association between a distinct condition and dementia was evaluated via logistic regression in the overall sample as well as in analyses stratified by gender and living environment.
- Results Individuals with dementia were more likely to be diagnosed with 15 comorbidity complexes, including Parkinson's, stroke, diabetes, atherosclerosis (supposed dementia risk factors) or fluids and electrolyte disorders, insomnia, incontinence, pneumonia, fractures and injuries (supposed sequelae).
Why it matters
This claims data study found that individuals with dementia were more likely to be diagnosed with 15 comorbidity complexes, including Parkinson's, stroke, diabetes, and atherosclerosis, as well as conditions like insomnia, incontinence, pneumonia, and fractures. It describes associations between conditions and dementia but does not test any treatment, cure, or prevention.
