I am running a regression using multiple variables in order to predict a binomial outcome. Two of my variables are numeric, most are categoric. My two numeric variables are age and bmi. I have calculated an odds ratio for each of those variables (e.g. if the bmi increases with 1 point, possibility of dependent variable changes). My goal is now to calculate an odds ratio and Low/High 95% CI for those variables, if the bmi and age increase with 5 points/years instead of 1. How do i calculate this?
