Popis: In this paper we evaluate the effects of heavy alcohol consumption on sexual behavior, HIV acquisition, and antiretroviral treatment (ART) initiation in a longitudinal open cohort of 1929 serodiscordant couples in Lusaka, Zambia from2002 to2012. We evaluated factors associated with baseline heavy alcohol consumption and its association with condomless sex with the study partner, sex outside of the partnership, and ART initiation using multivariable logistic regression. We estimated the effect of alcohol consumption on HIV acquisition using multivariable Cox models. Baseline factors significantly associated with women's heavy drinking (drunk weekly or more in 12-months before enrollment) included woman's older age (adjusted prevalence odds ratio [aPOR]=1.04), partner heavy drinking (aPOR=3.93), and being HIV-infected (aPOR=2.03). Heavy drinking among men was associated with less age disparity with partner (aPORper year disparity=0.97) and partner heavy drinking (aPOR=1.63). Men's being drunk daily (aOR=1.18), women's being drunk less than monthly (aOR=1.39) vs. never drunk and being in a male HIV-negative and female HIV-positive union (aOR=1.45) were associated with condomless sex. Heavy alcohol use was associated with having 1 or more outside sex partners among men (aOR drunk daily=1.91, drunk weekly=1.32, drunk monthly =2.03 vs. never), and women (aOR drunk monthly=2.75 vs. never). Being drunk weekly or more increased men's risk of HIV acquisition (adjusted hazard ratio [aHR]=1.72). Men and women being drunk weekly or more was associated (p
