open
weights and 'svy set' using wave 2+3, nurse health assesment and blood samples
100%
Description
I am evalutaing associations between kidney function (serum creatinine) determined in blood samples at the wave 2/3 nurse health assesment and all cause mortality up to wave 7. I also use self reported diagnoses from the main stage interview wave 2/3 for adjustment in the models.
I have found what I believe is the correct weight to use (indbdub_xw from xlabblood_ns.dta).
I do not use data from the following waves although I use the flag for diseased individuals provided (which is based on information from the following waves).
Besides being ceratin that I use the most appropiate weights I am also a bit confused about which variables that I should use when I 'svy set' my data. In xlabblood_ns.dta were I find the weight variable I do not find any 'psu' or 'strata' variables.
Yours sincerely

Dear Per-Ola Sundin,
Thank you for your question. Yes, the weight is correct. And for the svy set command you should use b_strata and b_psu variables that you can get from b_indsamp.dta of the mainstage.
Hope this helps,
Olena
