Subject:      how to calculate age-adjusted means & proportions with SPSS?
Content-Type: text/plain; charset="iso-8859-1"

Dear list members,

I'm involved in analyses where my dependent variables are body mass index
(BMI=kg/m2, a continuous
variable) and obesity (presence of BMI > 30 kg/m2, a dichotomous variable).
My independent variable of main interest is educational level (4 levels)

I would like to:

1. to present  a) BMI means, and b) Prevalence (%) of obesity, adjusted for
AGE (less educated participants are much older, and BMI and obesity
increases with age)

2. to test for statistical significance of possible linear trends in these
age-adjusted means and proportions across levels of education.

Can I obtain those estimates using the UNIVARIATE GENERAL LINEAR MODEL? How
should I do that?

Thanks in advance for any assistance!
