There was also a borderline significant trend association ( B = 0.62, SE = 0.32, p = 0.06) for males to be more likely to be diagnosed with dementia compared to females, and for higher levels of education to reduce the likelihood of dementia ( B = –0.29, SE = 0.17, p = 0.09), but there was no association between dementia and currently residing in urban compared to regional areas ( B = 0.01, SE = 0.33, p = 0.97).
