title: The influence of sleep and activity patterns on fatigue in women with HIV/AIDS.
abstract: The cause of HIV-related fatigue is most likely multifactorial. When presented as a chief complaint, clinicians often include an assessment of stress level, depression, anemia, infection, and amount of sleep and activity. The empirical bases for these evaluations vary in their validity and implementation in clinical practice, but the basis for evaluating adequate amounts of sleep and activity currently lacks empirical research. The purpose of this study was to describe HIV seropositive women's sleep and activity patterns related to their fatigue experience. Sleep and activity were assessed with wrist actigraphy to obtain objective measures of total sleep time, number of awakenings, and sleep efficiency, as well as level of daytime activity, 24-hour activity rhythm, and naps. This sample of 100 women with HIV/AIDS averaged only 6.5 hours of sleep at night, and 45% of the sample napped. CD4 cell counts were unrelated to sleep and fatigue measures. Compared to the low-fatigue group, the women with high fatigue had significantly more difficulty falling asleep, more awakenings from nighttime sleep, poorer daytime functioning, and a higher frequency of depressive symptoms. Findings from this study provide clinicians with empirically based support for detailed clinical evaluations of sleep and activity patterns, as well as anxiety and depression, in clients who complain of fatigue. Findings also provide data for potential interventions to improve sleep and activity in persons living with HIV/AIDS and to reduce fatigue and depressive symptoms.
