I was just wondering if physical activity and diet data are available from the shhs dataset?
They're included in the list of variables available from the parent cohorts ref: Table 1 in Quan SF, Sleep, 2012 "The Sleep Heart Health Study: Design, Rationale and Methods"; but I can't seem to find them in the actual dataset.
Thank you very much for chasing this up!! Much appreciated
Sorry, I meant to ask if 'weight20' (https://sleepdata.org/datasets/shhs/variables/weight20) was measured before or after 'weight' (https://sleepdata.org/datasets/shhs/variables/weight) in SHHS1.
They were both measured at SHHS1, what is the difference between the two?
I just want to confirm, was the variable 'weight20' collected between SHHS1 and interim? or at the same time as SHHS1?
Thanks Mrueschman, the 'known issues list' looks really useful!
I was just looking at the SHHS interim data on 'weight' (labelled as fuweight)
I noticed that the distribution of weight is very different from that in SHHS1 and SHHS2.
The maximum value for weight in the interim data is over twice as high as that in the SHHS1 or SHHS2 data
For those of you experiencing the same problem, know that 'fuweight' variable contains a mixture of 'kilograms' and 'pounds'. This is coded in "wtunits" where 1 =kilograms and 2=pounds.
Can I know how v0.7.0 is different form v0.6.0?
