Dear All,

I am working on the Sleep Heart Health Study 1 and I was wondering what is the average follow-up of the SHHS1 study? I was also wondering what types of CVD events are included in the 'any_cvd' variable of the SHHS1 dataset.

Thanks for your reply

Hey Ethan - I sent this via email, but posting here as well!

Thanks for your interest in the resource. The SHHS baseline (Visit 1 / "index") visits took place around ~1995. Some of the cohorts tracked incident CVD outcomes up until ~2010, so most subjects have somewhere between 10-15 years of follow-up tracking those outcomes (e.g., https://sleepdata.org/datasets/shhs/variables/censdate).

The second home PSG at SHHS Visit 2 appears to have occurred ~5-7 years after the index PSG (e.g., https://sleepdata.org/datasets/shhs/variables/stdatep).

The SHHS data contributor provided some documentation of the analytic database, which appears to contain some information on any_cvd coding: https://sleepdata.org/datasets/shhs/files/m/browser/documentation/SHHS_Documentation_of_Analytic_Database.pdf?inline=1

It looks like another Forum user also asked a similar question before: https://sleepdata.org/forum/cvd-variable/
