Self-Reported Sleep Disturbance is Associated With Lower CD4 Count and 24-Hour Urinary Dopamine Levels in Minority Women Living With HIV

A study 139 low income women with HIV found that after controlling for HIV viral load, length of time with HIV, HAART adherence, perceived stress and depression, greater sleep disturbance, by self-report, was associated with lower CD4 count and lower levels of dopamine. Poorer overall sleep quality, measured by PSQI, was marginally associated with CD4 count.
