“…Objective measures of sleep, such as polysomnography, have shown longer sleep latency, shorter total sleep time, reduced sleep efficiency, and more time spent in Stage 1 sleep in HIVC patients compared to healthy controls (Wiegand et al, 1991). On subjective measures of sleep, a study of 50 HIVC patients by Cohen, Ferrans, Vizgirda, Kunkle, and Cloninger (1996) indicated that 60% of participants reported moderate or severe restlessness during sleep, 44% reported being moderately or very tired in the morning, 26% reported sleep quality as poor or very poor, and 70% reported awakening more than once per night.…”
