Evaluation of the mortality impact of a national-scale disease-prevention intervention is complicated by the endogeneity—those individuals who receive the intervention may be healthier than those who did not. This population-based study assesses the mortality impact of Togo’s 2004 nationwide child health campaign that distributed insecticide-treated nets (ITNs) to mothers of children ages 9–59 months. We first demonstrate that a one-time campaign that restricts programme eligibility to households with a surviving child inadvertently excludes some households with a high child-mortality risk, by comparing mortality rates before and after the campaign according to a household’s eligibility status. We then estimate a two-equation model for ITN receipt and mortality risk in order to address the potential endogeneity of ITN receipt. Results show that among households with a child eligible to receive an ITN, living in a household with ITNs significantly reduced mortality among children ages 20–59 months even after controlling for endogeneity.
