Abstract

Population aging is a global phenomenon that will continue to reach all regions of the world. The main changes that can be followed by the aging are with respect to cognitive and functional aspects. This study aimed to estimate the incidence of cognitive and functional changes in the elderly living in isolated community, reminiscent of quilombo, located in the northeastern of Goias state, called Kalunga. We conducted a longitudinal study with noninvasive methods, based on primary data of cognitive and functional changes of the elderly who participated in prevalence study in 2011. Were collected and analyzed identification data (age, gender), socio-demographic factors (education, place), cultural and prior morbidities (hypertension, diabetes) participants through semi-structured questionnaire. The cognitive and functional data were obtained by applying the Mini Mental State Examination (MMSE) and the Pfeffer Functional Activities Questionnaire (PFAQ), respectively. In total were reassessed 43 elderly. Most were male (51.2%), married (69.8%), illiterate (90.7%) with a mean age of 74.2 years, hypertension (53.5%) and smoker (48.8%). The incidence of individuals with cognitive and functional change was 4% year, similar in comparison to other studies on cognitive disorders and dementia. Only low levels of schooling and the presence of diabetes mellitus presented a significant association with the individuals' cognitive and functional profile. However, there was a significant decline in cognition and functionality of these assessed in 2011 and reassessed in 2014.
