Eksperimentel: ART home delivery + enhanced nutrition counseling
Community health workers visit participants at home (maintaining patients' prior clinic visit frequency) to deliver antiretroviral therapy (ART) and to provide standard plus enhanced nutrition counseling.
|
Community health workers visit participants who are clinically stable on antiretroviral therapy (ART) at home (maintaining patients' prior clinic visit frequency) to deliver ART.
Clinically stable on ART was defined as 1) taking ART for at least six months, 2) having had a CD4-cell count >350 cells/μL or a suppressed viral load at six or more months after ART initiation, and 3) the patient's most current CD4-cell count must have been >350 cells/μL or the most current viral load must have shown viral suppression, with the last measurement not taken more than 12 months ago.
Community health workers visit participants at home to provide standard counseling (focusing on family planning, prevention of HIV transmission, and ART adherence) plus enhanced nutrition counseling (covering food production and dietary advice).
In addition, participants who state that they have access to a plot of land or garden to grow vegetables receive a pack of seeds (amaranth, cowpea, or pumpkin) at enrolment.

Eksperimentel: ART home delivery + no enhanced nutrition counseling
Community health workers visit participants at home (maintaining patients' prior clinic visit frequency) to deliver antiretroviral therapy (ART) and to provide standard counseling.
