Description

Hello. I am working on the understanding society database looking specifically at the self-completion questionnaire data for the sleep and health questions. I am carrying out a longitudinal regression analysis to explore the association between change in individual sleep status on the health outcomes from wave 1 – wave 4 controlling for a number of other variables. I just wanted to double-check which longitudinal weight I should apply to the regression analysis – I am thinking ‘d_indscus_lw’? And for descriptive statistics to describe the initial sample at wave one, would I just use the ‘a_indscus_xw’ weighting?

Also, if I wanted to incorporate nurse assessment CRP biomarker data at Wave 2 as a mediator or examine the association from Wave 1 sleep status to Wave 2 biomarker status, which weighting would I apply in this case 'b_indnsus_lw'? And lastly, is there a weighting that’s applicable perhaps to look at the association from Wave 2 biomarker status to Wave 4 sleep?

Thank you,
Esther.
