Objective: To characterize specifi c types of sleep problems experienced by adults with HIV. Method: The design was cross-sectional involving sleep questionnaires, diaries, and wrist actigraphy. The convenience sample included 290 adults living with HIV, 22-77 years of age. Measures included self-report for sleep onset latency, and wrist actigraphy estimates of total sleep time at night, wake after sleep onset, and daytime sleep. Results: Nearly half (45%) of the sample slept < 6 h per night. Diffi culty falling asleep was reported by 34%, and 56% had fragmented sleep according to actigraphy; 20% had both problems, and 30% were good sleepers. Participants reporting diffi culty falling asleep had actigraphy and clinical measures similar to the good sleepers, but subjectively they experienced greater sleep disturbance and symptom burden (particularly anxiety and morning fatigue) and reported more use of sleep medication. Participants with fragmented sleep reported low levels of sleep disturbance and symptom burden similar to the good sleepers, despite actigraphy measures indicating they obtained less sleep both at night and during the day. Sleep fragmentation was also associated with sociodemographic factors and slightly lower CD4+ T-cell counts. Participants reporting both sleep problems had actigraphy and clinical profi les similar to those who had only fragmented sleep, but their symptom experience was similar to participants with only sleep initiation diffi culties.
Types of Sleep Problems in Adults Living with HIV/AIDS
S C I E N T I F I C I N V E S T I G A T I O N SS leep problems affect about 30% of the population in the United States and are associated with higher healthcare utilization and use of sleep medication, as well as poor work performance and mood disorders.1 Adults living with a chronic illness are at higher risk for sleep problems, and depending on the definition, sleep problems are experienced by 30% to 100% of HIVpositive adults. [2][3][4][5][6][7][8][9] It is unclear what type of sleep problem adults with HIV experience, or whether their sleep disturbance is related to the infection itself or to the medical treatment and side effects of medications. Sleep disturbance is not only prevalent, but also one of the more intense and distressful symptoms experienced in this population. [8][9][10] In HIV infection, poor sleep has been associated with disease progression, medication therapy, employment status, and lack of knowledge about behaviors that promote good sleep. [11][12][13][14] The specifi c type of sleep disturbance experienced by this population needs to be better understood in order to provide the most effective intervention to improve symptoms, daytime functioning, and quality of life. 8,[15][16][17][18] Fragmented sleep occurs in chronic health conditions and may not even be perceived by the patient. 19,20 With this type of sleep loss, it is rare to fi nd complaints of initiation insomnia, but complaints of daytime sleepiness or fatigue are common and can lead to diffi culty concentrat...
