Andres,
The simplest way is using the formula: SE(StdBeta_i) =
[SD(Y)/SD(X_i)]*SE(beta_i) all of those numbers are available from regress
output. Also, you could running a "regress" command using the standardized
Xs variables in place of the original variables.
Anyway you have those standard errors, you will be able to calculate 95% CIs
for each coefficient using StdBeta +/- 2*SE(StdBeta).

Subject: st: Confidence Interval for Standardized Beta Coefficients in
Linear Regression
Dear Stata List Members,
How can I obtain the Confidence Intervals for Standardized Beta
Coefficients in Linear Regression Analyses?
Thank you very much,
Andrés.
