We start with a data step incrementing BRFSS_h to BRFSS_i. Then we make MARGRP for martial group, EDGROUP for education, we recode GENHLTH into GENHLTH2, we recode INCOME2 into INCOME3, we create RACEGRP out of _MRACE1, we create EXERANY3 out of EXERANY2, we make HLTHPLN2 from HLTHPLN1, and we recode the BMI category variable.
