st: geometric mean with svy (version 9.0)

Dear Stata Guru's,

I want to compute geometric mean and SD from survey data. Here is an example:

. svy:mean lnbenz,over (sex) (running mean on estimation sample)

Survey: Mean estimation

Number of strata = 13 Number of obs = 647 Number of PSUs = 27 Population size = 1.5e+08 Design df = 14

_subpop_1: sex = 0. Male _subpop_2: sex = 1. Female

-------------------------------------------------------------- | Linearized Over | Mean Std. Err. [95% Conf. Interval] -------------+------------------------------------------------ lnbenz | _subpop_1 | .3884244 .2993531 -.2536241 1.030473 _subpop_2 | .1070038 .1907388 -.3020902 .5160979 --------------------------------------------------------------

I can manually type Di exp(0.3884244)

For each of the category but I have to type hundreds of time since I have several variables. I tried egenmore option but I couldn't find how to use it with svy command. Can any help point me to the resource to find more info? Is there program I can use to automate this process? Ideally I would like Stata to run the survey command and then use the mean value to compute geometric mean and SD. Any help will be greatly appreciated
