st: mixed models doubt in how to interpret the Coef

Dear all,
I am writing you because I am performing a longitudinal mix models
analyses as the following
xi: xtmixed sdnn i.year_of_visit gender age smoke alcohol
waistcinrcunfrence_std pa_std tasis_std trg_std glu_std hdl_std
|| id: i.year, covariance(identity)
I have 3 years of data, my main doubt now is how can I interpret my
Coefficient? If my results I have that the Coef of Glu is -3.35 and
the p is 0.001. Can I say that when I increase by one unit Glu sdnn
decreases -3.35 ms over 3 years? So Glu is associated with a decrease
in sdnn over time.
thank you so much for your help,
regards
Luisa
