Table 1 Characteristics of the participants of the study- ELSA-Brasil (2008–2010). Note. Memory = word-list learning + word-list delayed recall + word recognition tests. Data are presented as mean ± SD, median [IQ] or n (%). N: number; %: percentage; SD: standard deviation; IQ: interquartile range. A1c: glycated hemoglobin; Total Col-HDL-C – total cholesterol/High density cholesterol ratio.
