Little is known about sleep problems in persons with human immunodeficiency virus (HIV) infection. The article reports a study that assessed quantitative and qualitative aspects of sleep in a group of men and women with HIV infection and examined sleep parameters in regard to the degree of immune function. The convenience sample of 50 persons was drawn from an HIV clinic in a large midwestern metropolitan area. Subjects identified a variety of problems with their sleep that were not significantly related to their immune status. The findings of this study indicate that nurses should perform a sleep history and assessment on all persons with HIV infection to identify those in need of intervention.
