Compare two coefficients for the same variable between two separate datasets

[eunkisoo]

Hi!

I would like to compare the effects of variables between men and women to see whether the effects of the same variable on a dependent variable are different by sex. So I construct men's and women's data, respectively. In my research, a response variable is obesity(0=obese, 1=normal) and I run a logistic analysis.

I get the following results:

                           Men               Women                        Men vs. Women

Education   -.037(.002)***      -.047(.011)***              significant difference?

Income       -.122(.003)**       -.075(.032)***              significant difference?

I can say that education and income are related to obesity for both men and women. However, I also wonder whether there is a difference of the effects of education and income on obesity between men and women. This requires a comparison of two coefficients from men and women for the same variable. How can I test whether there is a difference of coefficients for each variable, education and income between men and women in SAS?

Thanks!

From the dataset, education is categorical variable is it correct?
If there is a chance can you share the data?

You need combine  men's and women's data into one table, and use ESTIMATE .

class SEX;
...........
estimate 'F vs M' sex 1 -1 ;
