Smoking Not Linked To Higher Dementia Risk: Study
A statistical method called competing risk analysis was used to determine whether there was a connection between smoking and dementia.
The data demonstrated that smoking was associated with a risk of earlier death but not dementia.
It is no secret that smoking increases the risk for cancer, heart disease, diabetes and even blindness. But puffing on a cigarette is not associated with a higher risk of dementia, says a new study.
The present study, published in the Journal of Alzheimer's Disease, stands in contrast to the previous research that found a correlation between smoking and dementia.
"The underlying data (in those studies) was solid, but the analysis didn't take into account the idea of competing risk of mortality, which we felt was an important factor to consider in this case since smoking is so strongly associated with earlier death," Erin Abner from University of Kentucky, who was among the the researchers, said.
For the study, the researchers included 531 initially cognitively-normal people.
They used a statistical method called competing risk analysis to determine whether there was a connection between smoking and dementia.
The data demonstrated that smoking was associated with a risk of earlier death -- but not dementia.
"To be clear, we are absolutely not promoting smoking in any way.
"We're saying that smoking doesn't appear to cause dementia in this population," Abner added.
