OddsRatio of Interaction term from Prosurvey logistics

Hello,

I discovered that i could find the OR of interaction terms using Proc logistics but i could not do the same using procsurvey logistics. I was wondering the reason may be?

For example, this option gives me an OR for the interaction term, but it doesn't with ProcSurveylogistics

proc logistic data = newage;
weight fwc;
class sex (ref = '0') race(Ref = '0') BreastFed (ref= '0') smokes(Ref= '0') (ref='0') ;
Model asthma (event ='1') = sc_age_years sex race BreastFed smokes BreastFed*smokes/
clodds=wald; units sc_age_years=1/default=1;oddsratio BreastFed/diff=ref;
run;

Proc SURVEYLOGISTIC does not have an ODDSRATIO statement like Proc LOGISTIC. Instead you could use the LSMEANS statement like in the 1st example of the paper linked below.
