st: difference in odds ratio

Hi listers,
I have run two separate logistic regression models for two age groups (dependent and independent variables are the same in the two regressions). I want to find out whether the odds ratios for the two groups are statistically significantly different from each other, i.e. I am interested in OR(A) - OR(B) and the confidence interval around the difference.
Could anyone suggest the best way to get the confidence interval and p-value of the difference in odds ratios?
Many thanks,
Shehzad
