I am trying to understand how to interpret the health conditions variables in wave 2.
In wave 1 people are asked to identify whether they have ever been diagnosed with a particular condition (hcond#), if so at wgat age (hcona#) and whether they still have it (hconds#).
In wave 2 they seem only to be asked whether they have any newly diagnosed conditions - all hcond variables in wave 2 refer to conditions diagnosed since the last interview.
My questions are (1) am I correct in this interpretation of the questions?
(2) how can I tell whether someone retains the health condition they had in W1 in W2.
