School-based Deworming: A Low-Cost Intervention Achieving High-Impact Benefits

There is a difference between a low-cost program and a cost-effective program. Implementing a low-cost program is not sufficient - we want to ensure that the impacts of the program are measurable and that the benefits outweigh the costs - this is what makes a program truly cost-effective. Putting these two parts of the equation - costs and benefits - together, we can estimate the value for money of our program.

Today, Evidence Action welcomes the release of a new study that shows that mass deworming of children has a significant positive effect on child weight and is highly cost effective, with a weight gain per dollar 35 times greater than school feeding programs.

This study strongly refutes findings from a previous critique of mass deworming of children in developing countries with high levels of parasitic worms, a Cochrane meta analysis by Taylor-Robinson et al (2015.) that questioned the long-standing World Health Organization (WHO) policy supporting mass deworming.

The new research, “Does Mass Deworming Affect Child Nutrition?: Meta-analysis, Cost-Effectiveness, and Statistical Power” was authored by Kevin Croke, Joan Hamory Hicks, Eric Hsu, Michael Kremer, and Edward Miguel.
