Utilizing the lowest consumption regularity classification as a guide, i projected the brand new sex-certain chances rates (ORs) and you may 95% count on times (CIs) of having build diabetes about the consumption of soy food of the logistic regression data immediately following modifying getting decades and you may part of residence (Design step one). Model 2 try next modified to have body mass index (BMI) ( 2 ), history of blood pressure levels (sure or no), genealogy of diabetic issues (yes or no), sports occasions ( dos ) one of both males and females by this new menopausal updates (premenopausal and you will postmenopausal) one of many female classification had been used.
