How to Deal with Missingness in Health Variables Over Time

I'm looking t health variables in UKHLS waves 1-11, and may individuals have incomplete data across the full timespan.

I'm wondering whether "missingness" across time/waves in UKHLS is generally considered MCAR/MAR/NMAR, as in this case it may indeed be linked to episodes of illness, and how other researchers have dealt with the issue of missing data?

I am dubious about imputing values using multiple imputation when the values I would use to impute are the same ones I will be entering into a multilevel analysis of health outcome.

Any advice or references on how to deal the missingness across time/waves gratefully received!

Hello Sue,

Which health variables are you referring to? For some questions, not everyone is asked the question so the missingness may not be item non-response. Also, have you looked at the Health Conditions questions FAQ, as there were changes to how these questions are asked over the years. Go to the FAQ page: And then click on "Questions about variables" and then click on the question "How were health conditions questions asked"

Best wishes,
