That would give you an approximation of the marginal effects,
which is fine, but it has specific advantages and disadvantages
compared to odds ratios.

Don't forget to specify the -robust- option.

It will probably be OK as long as the predicted probabilities
don't get too close to either 0 or 1 (I have heared the rule
of thumb that the predicted probabilities should lie between
.2 and .8).

Hope this helps,
Maarten
