Abstract

OBJECTIVE:

: To study the prevalence of sleep-disordered breathing (SDB) in Vietnam- era veterans.

METHODS:

: This was an observational study of Vietnam-era veterans using unattended, overnight polysomnography, cognitive testing, and genetic measures.

RESULTS:

: A sample of 105 Vietnam-era veterans with posttraumatic stress disorder: 69% had an Apnea Hypopnea Index >10. Their mean body mass index was 31, "obese" by Centers for Disease Control and Prevention criteria, and body mass index was significantly associated with Apnea Hypopnea Index (Spearman r = 0.41, N = 97, p < 0.0001). No significant effects of sleep-disordered breathing or apolipoprotein status were found on an extensive battery of cognitive tests.

CONCLUSION:

: There is a relatively high prevalence of SDB in these patients which raises the question of to what degree excess cognitive loss in older PTSD patients may be due to a high prevalence of SDB.
