Variables such as years of education, income and place of residence showed a positive association with cognitive function. Adults, who were more educated, lived in urban areas and had a better income, had better cognitive function. Meanwhile, the probability of cognitive impairment increased with age. Social support has been described as a buffer to prevent cognitive impairment in older adults; the strongest effect was identified for respondents aged 70–80. Before this age, older adults had personal resources that enabled them to confront daily difficulties. After of this age, it is likely that some degree of impairment was present on adults. There was a window of opportunity for those aged 70–80, as they appeared to benefit the most by the presence of social support. Although traditionally the literature described the positive effects of social support on the health of individuals, it is important to consider its positive influence must be framed in the course of life of the subject, where resources change over time.
