The Sleep Heart Health Study (SHHS) is a prospective
cohort study designed to investigate the relationship between
sleep disordered breathing and cardiovascular disease.
Participants were recruited from
nine existing epidemiological studies in which data
on cardiovascular risk factors had been collected
previously. The "parent" cohorts
include:
- The Framingham Offspring Cohort
- The Hagerstown and Minneapolis/St.
Paul sites of the Atherosclerosis Risk in
Communities (ARIC) study
- The Hagerstown, Sacramento
and Pittsburgh sites of the Cardiovascular
Health
Study (CHS)
- The Strong Heart Study sites in South
Dakota, Oklahoma, and Arizona
- Studies of respiratory disease
in Tucson and of hypertension in New York
From these parent cohorts, a sample of participants
who met the inclusion criteria (age 40 years or
older; no history of treatment of sleep apnea;
no tracheostomy; no current
home oxygen therapy)
was invited to participate in the baseline examination
of the SHHS, which included an initial polysomnogram
(SHHS-1). Several cohorts over-sampled
snorers in order to increase the study-wide prevalence
of sleep-disordered breathing. In all, 6441 individuals
were enrolled between November 1,
1995 and January 31, 1998. During exam cycle 3
(January 2001- June 2003), a second polysomnogram
(SHHS-2) was obtained in 3295
of the participants.

Data Access
Currently a subset of 1,000 of the 3,295 SHHS-2 studies are available for
download. These studies come from the following sites:
- The Framingham Offspring Cohort
- The Hagerstown and Minneapolis/St.
Paul sites of the Atherosclerosis Risk in
Communities (ARIC) study
- The Hagerstown, Sacramento
and Pittsburgh sites of the Cardiovascular
Health
Study (CHS)
Selected SHHS-1 studies will soon be available.
