Abstract Objective The HPTN 071 (Pop ART ) trial is examining the impact of a package including universal testing and treatment on community‐level HIV incidence in Zambia and South Africa. We conducted a nested case–control study to examine factors associated with acceptance of home‐based HIV testing and counselling ( HB ‐ HTC ) delivered by community HIV ‐care providers ( CH iPs) in Pop ART intervention communities. Methods Of 295 447 individuals who were offered testing, random samples of individuals who declined HB ‐ HTC (cases) and accepted HB ‐ HTC (controls), stratified by gender and community, were selected. Odds ratios comparing cases and controls were estimated using multivariable logistic regression. Results Data from 642 participants (313 cases, 329 controls) were analysed. There were no differences between cases and controls by demographic or behavioural characteristics including age, marital or socio‐economic position. Participants who felt they could be open with CH iPs ( AOR : 0.46, 95% CI : 0.30–0.71, P < 0.001); self‐reported as not previously tested ( AOR : 0.64; 95% CI : 0.43–0.95, P = 0.03); considered HTC at home to be convenient ( AOR : 0.38, 95% CI : 0.27–0.54, P = 0.001); knowing others who had accepted HB ‐ HTC from the CH iPs ( AOR : 0.49, 95% CI : 0.31–0.77, P = 0.002); or were motivated to get treatment without delay ( AOR : 0.60, 95% CI : 0.43–0.85, P = 0.004) were less likely to decline the offer of HB ‐ HCT . Those who self‐reported high‐risk sexual behaviour were also less likely to decline HB ‐ HCT ( AOR : 0.61, 95% CI : 0.39–0.93, P = 0.02). Having stigmatising attitudes about HB ‐ HTC was not an important barrier to HB ‐ HCT uptake. Men who reported fear of HIV were more likely to decline HB ‐ HCT ( AOR : 2.68, 95% CI : 1.33–5.38, P = 0.005). Conclusion Acceptance of HB‐HTC was associated with lack of previous HIV testing, positive attitudes about HIV services/treatment and perception of high sexual risk. Uptake of HB‐HCT among those offered it was similar across a range of demographic and behavioural subgroups suggesting it was ‘universally’ acceptable.
