st: Interpreting coefficients in GLM

Hello stata users,
I am estimating a GLM by using the following options: family(nbinomial) link(log) robust
How do I interpret the coefficients I get?
I used to employ negative binomial regression (nbreg) and interpreted coefficients in terms of percentages (after exponentiating them)
and I am wondering if I can do the same thing in the glm.
For instance, if I get .80 after exponentiating a coefficient, can I can X reduces Y by 20%?
Or, I can get "risk ratios" when I type "eform" with the glm command. What is the typical way of interpreting risk ratios?
If I get a risk ratio of .20, what is the relationship between X and Y? I am not familiar with this type of ratio.
I am sorry if this is a dumb question but I am really desperate for some help.
I will greatly appreciate your input!
J
