Using the same reference group , those who abstained from sex in the previous month had 30 % increased odds of low adherence ( aOR = 1.30 , 95 % CI : 1.05 to 1.62 ) and participants in nonpolygamous marriages who reported sex with both their primary and other partners and < 100 % condom use were almost twice as likely to be low adherers ( aOR = 1.76 , 95 % CI : 1.01 to 3.08 ) .
