Objective: to identify the healthy aging profile in octogenarians in Brazil. Method: this population-based epidemiological study was conducted using household
interviews of 335 octogenarians in a Brazilian municipality. The decision-tree
model was used to assess the healthy aging profile in relation to the
socioeconomic characteristics evaluated at baseline. All of the tests used a
p-value < 0.05. Results: the majority of the 335 participating older adults were women (62.1%), were aged
between 80 and 84 years (50.4%), were widowed (53.4%), were illiterate (59.1%),
had a monthly income of less than one minimum wage (59.1%), were retired (85.7%),
lived with their spouse (63.8%), did not have a caregiver (60.3%), had two or more
children (82.7%), and had two or more grandchildren (78.8%). The results indicate
three age groups with a healthier aging profile: older adults aged 80 to 84 years
(55.6%), older adults aged 85 years and older who are married (64.9%), and older
adults aged 85 and older who do not have a partner or a caregiver (54.2%). Conclusion: the healthy aging profile of octogenarians can be explained by age group, marital
status, and the presence of a caregiver.
