Results : Participants were mostly male (55%), between75-89 age groupe with high school diploma(29.1 %),coupled(69% ),retirees(68.4%),polypharmacy(58.6%) and blood group O(37.6%). According to the multivariate regression analysis: age, low levels of D3, polypharmacy ,personal cancer history and chronic anemia were the main predictors for dementia, while studying habbits, regular physical&social activites,egg intakes were the main independent protective factors against dementia.
Conclusion: The findings of current study while alarming, indicate significantly that nutrition, active life styles, polypharmacy, reading habbits and anemia need to be considered more throughly than before by policy makers , employees and retirees.
