To measure the effects of information, a challenge, and a conditional cash transfer on take-up of voluntary medical male circumcision (VMMC).
A randomized, controlled experiment with 4000 postcard recipients in Soweto (Johannesburg), South Africa.
We examined differences in take-up of several decisions in the VMMC cascade between the control arm and each of several intervention arms using logistic regression.
Logistic regression analysis indicated that the group offered US $10 as compensation and the group challenged with "Are you tough enough?" had significantly higher take-up of the VMMC procedure than did the control group [odds ratios, respectively, 5.30 (CI: 2.20 to 12.76) and 2.70 (CI: 1.05 to 6.91)]. Similarly, the compensation group had significantly higher take-up of the VMMC counseling session than did the control group [odds ratio 3.76 (CI: 1.79 to 7.89)]. The analysis did not reveal significantly different take-up of either the VMMC counseling session or the procedure in the partner preference information group compared with the control group [odds ratios, respectively, 1.23 (CI: 0.51 to 2.97) and 1.67 (CI: 0.61 to 4.62)]. The analysis did not reveal significantly higher take-up of the VMMC nurse hotline in any intervention group compared with the control group [odds ratios for US $10, information, and challenge, respectively, 1.17 (CI: 0.67 to 2.07), 0.69 (CI: 0.36 to 1.32), and 0.60 (0.31 to 1.18)].
Among adult males in Soweto, South Africa, compensation of US $10 provided conditional on completing the VMMC counseling session compared with no compensation offer and a postcard with a challenge, "Are you tough enough?" compared with no challenge, resulted in moderate increases in take-up of circumcision.
评估信息、一项挑战及有条件现金转移对男性自愿包皮环切术（VMMC）接受率的影响。
在南非约翰内斯堡索韦托对4000名明信片收件人进行的随机对照试验。
我们使用逻辑回归分析了对照组与几个干预组中VMMC流程中几个决策的接受率差异。
逻辑回归分析表明，获得10美元补偿的组和受到“你够强硬吗？”挑战的组接受VMMC手术的比例显著高于对照组[优势比分别为5.30（95%置信区间：2.20至12.76）和2.70（95%置信区间：1.05至6.91）]。同样，获得补偿的组接受VMMC咨询服务的比例显著高于对照组[优势比3.76（95%置信区间：1.79至7.89）]。分析未发现伴侣偏好信息组接受VMMC咨询服务或手术的比例与对照组有显著差异[优势比分别为1.23（95%置信区间：0.51至2.97）和1.67（95%置信区间：0.61至4.62）]。分析未发现任何干预组接受VMMC护士热线服务的比例显著高于对照组[10美元补偿组、信息组和挑战组的优势比分别为1.17（95%置信区间：0.67至2.07）、0.69（95%置信区间：0.36至1.32）和0.60（95%置信区间：0.31至1.18）]。
在南非索韦托的成年男性中，与无补偿提议以及无“你够强硬吗？”挑战的明信片相比，完成VMMC咨询服务后给予10美元补偿以及提出“你够强硬吗？”的挑战，会使包皮环切术的接受率适度提高。
