Two questions:
1) I would like to calculate the age-specific and age-adjusted rates of hospitalizations among the exposed and unexposed in my population-based study using Poisson/Negative Binomial models...not just the IRR. Any ideas how to do this or even if it is possible?

2) Alternatively, how can I obtain an age-adjusted rate just using standard IR calculations? I seem to only be able to calculate the unadjusted rate and a M-H RR using the command IR. any options here?

Most of the papers I have read using Poisson analysis report crude rates without Poisson (although one can calculate CIs with a Poisson distribution--not sure how to do that in Stata). Many thanks in advance.
