Patients living with HIV commonly experience sleep disturbances, depression, excessive daytime sleepiness and fatigue, which negatively affect antiretroviral medication adherence. Few studies have examined relationships between these symptoms and medication adherence in women living with HIV or examine the mechanisms through which these symptoms affect adherence. The purpose of this study was to examine the associations between sleep quality, excessive daytime sleepiness and medication adherence, and energy/fatigue and depression as mediators of these relationships among 206 women living with HIV. Correlations, t-tests and hierarchical regression analysis were utilised. The majority of participants (93.2%) were African American or Black. The average age of participants was 43.3 years and average years infected was 9.6. More than half of the women reported poor sleep quality and, on average, participants reported moderate daytime sleepiness, high depressive symptoms and moderate levels of fatigue. Additionally, both depression and low energy/fatigue were identified as significant mediators of the relationship between sleep quality and medication adherence. Depression also significantly mediated the relationship between excessive daytime sleepiness and medication adherence. The findings from this study highlight the impact of sleep on medication adherence and associated mechanisms and emphasise the need for healthcare providers to assess and address sleep factors when providing care for patients living with HIV.
