Julia Alison Critchley

I can't really follow your question. What is the outcome? Maybe showing a bit of the data would help other work out what you are trying to do.

Saima Afaq

Dear Julia,

I am studying the association of Physical activity with glucose and incident Type two diabetes. I have stratified my results for Ethnicity (south Asians and europeans), gender (male and female) and 4 age groups (30-39,40-49,50-59 and 60 or above).

I stratified my results because of a strong correlation between the age and physical activity which was affecting the results. is there any other way to deal with a strong correlation between predictors?

After getting my results for all these strata, i want to use meta analysis to get one value for each ethnic group.

I hope I am making sense!

Please suggest what should I do.

Thank you

Saima
