Skinny professionals was in fact even more more likely current cigarette smokers and you can to possess all the way down scores to the MMSE than others about almost every other Body mass index categories. Users having class II/morbid obesity had the lower indicate years of education, obtained lower in the brand new SPPB, and you can had been expected to report blood pressure, all forms of diabetes, and ADL impairment than those in other Body mass index groups.
