adjusted odds ratio for age per 10-year decrease

[vincenza cofini]

I'm doing logistic regression with continuous age and 4 other categorical variables.
I was asked to calculate the adjusted odds ratio for age per 10-year decrease , can anyone help me?
thank you

your situation is not entirely clear to me but I think that either of the following will work: (1) divide age by 10 and re-estimate; (2) take the OR for a 1 year difference and raise to the 10th power (note that I am making some assumptions because you provided so little information; any of those could be wrong; please read the FAQ)
