Imputation and derivation

Derivation
variable: glucunits_fast [fasted blood glucose result] (table[s]: derived variable)
variable: diadiab [ever diagnosed with diabetes] (table[s]: ncdk_persexam & ncdl_persexam)
Results of fasting blood glucose levels collapsed into categories, excluding participants who reported a previous diabetes diagnosis.
gen fastgluc=0 if glucunits_fast<5.6 & glucunits_fast!=.
replace fastgluc=1 if glucunits_fast>=5.6 & glucunits_fast<7.0
replace fastgluc=2 if glucunits_fast>=7.0 & glucunits_fast!=.
replace fastgluc=. if diadiab==1
