Abstract
INTRODUCTION AND OBJECTIVES: Obstructive sleep apnea (OSA) is a prevalent disorder among military veterans. The goal of this study is to compare the polysomnographic patterns of OSA in military veterans who have a history of post-traumatic stress disorder (PTSD) with those of veterans who have not PTSD.
MATERIALS AND METHODS: Seventy-two Iranian military male veterans were classified into two groups: those with PTSD (40 cases) and those without PTSD (32 cases). Each participant was diagnosed with OSA using an overnight polysomnography, during which sleep-related parameters such as sleep efficiency (SE) and apnea-related events were detected. The body mass index (BMI) and Epworth Sleepiness Scale (ESS) were also assessed.
RESULTS: For the PTSD group, mean age was 53.83 ± 7.3 years, elapsed time since they participated in war was 28.3 ± 3.4 years, apnea-hypopnea index (AHI) was 41.2 ± 27, SE was 77.7 ± 17.55%, ESS was 7.93 ± 2.04, BMI was 26.5 ± 5.7, and PLM index was 12.725 ± 8.64. The above respective parameters for the non-PTSD group were 51.33 ± 5.9 years, 28.3 ± 3.4 years, 30.33 ± 14.7, 82.4 ± 15.65%, 10.08 ± 3.02, 31.5 ± 6.7, and 8.8 ± 3.54. The relationships of AHI with ESS and BMI were not significant in PTSD group.
CONCLUSION: OSA in military veterans suffering from PTSD presents more often with insomnia than obesity or increased daytime sleepiness. These findings are different from those typically seen in non-PTSD veterans with OSA.
