Birthplace linked to higher cardiac mortality & dementia risk.
Those born in high stroke-mortality states (the so-called stroke belt) in the South: Alabama, Arkansas, Louisiana, Mississippi, Oklahoma, Tennessee, South Carolina and West Virginia, are much more likely to develop dementia, according to a recently published article by JAMA Neurology.
The risk of developing dementia in the next 20 years was 30 percent more for people born in these states (plus Alaska), compared to 21 percent for those born elsewhere. This study also links cardiovascular disease to dementia.
African Americans in the analysis were almost 10 times more likely to have been born in one of the stroke belt states, and had the highest dementia risk of all. African American adults from the nine states with high stroke mortality rates were 67 percent more likely to develop dementia than non-African American people born outside of the stroke belt. African Americans born outside the stroke belt were 48 percent more likely to develop dementia than all others born outside the stroke belt.
Non-African American adults born in the states with high stroke mortality rates were 46 percent more likely to develop dementia than non-black people born elsewhere, the study also found.
