The controversy to accept it as an independent risk factor is, among other things, differences in the designs, especially in the epidemiological observation time and age, income of individuals under study. The impact is greater when incorporated juveniles (under 40 years) and especially when the analysis is performed in populations with follow up over 10 years.
