Deworming PillsThis July, the National Bureau of Economic Research (NBER) published data from a longitudinal research study that looked at how deworming Kenyan children affected their economic outcomes. Youths took deworming medication under professional supervision and were revisited 20 years later by researchers. Economists used these findings to estimate the impact of deworming pills. They find an enormous effect: taking deworming pills during childhood boosts household income by as much as 13% in adulthood.

NBER Research

Deworming has a positive effect on children’s education; reducing absenteeism and dropping out of school. However, this study finds that in addition to, and perhaps as a result of improved education, deworming increases the likelihood of working in nonagricultural jobs with higher incomes. If students are healthier from a younger age and succeed in school, they have a higher chance of bettering their futures. However, it must be noted that the study only found this future income boost applied to men, suggesting that although deworming medicine increases better education, it does not improve economic mobility for women. Further research is necessary to study this gender gap and its causes.

Further Research

The World Health Organization (WHO) and The World Bank have been funding the distribution of deworming pills in Africa for many years now. In sub-Saharan Africa, there are high infection rates of intestinal worms, especially among school-age children. Worms stunt children’s development and affect their ability to function. Deworming kids is inexpensive, and it results in healthier individuals and communities. Additionally, when previous generations are treated, the current generations are shown to reap the benefits. With deworming programs having such clear positive results, many organizations such as the WHO support and supply school-based deworming in sub-Saharan Africa, as well as other developing countries.

Deworming pills cost less than a dollar per child treated, so the return on deworming programs is enormous. For instance, the NBER study predicts a 37% return on deworming investments. However, these researchers acknowledge that there is a low chance this effect is statistically significant. In other words, they may have vastly overstated the effect of deworming pills on future outcomes.

Deworm the World

Hassenfeld is the co-founder of GiveWell, a nonprofit dedicated to finding and rating giving opportunities for donors. GiveWell backs an initiative called “Deworm the World,” which they consider a “priority program” because of how cheap deworming is and how beneficial the outcome may be. GiveWell also hires and trains monitors to attend schools, conduct training sessions, and implement distributions of deworming pills to students to ensure program efficiency.

Deworm the World spent $2.2 million more dollars in 2018 on deworming than in 2017. However, the company is continually seeking funding because they hope to expand its programs in Kenya, India, Pakistan and Nigeria.

Concluding Thoughts

This study suggests that deworming may strengthen entire communities over time, raising people out of poverty and improving their countries’ GDP. One study cannot completely explain the financial impact of deworming; however, it is clear that further research is needed and that children’s lives are being changed for the better. Previous research has shown that supporting healthcare systems and eradicating illnesses in developing countries leads to their growth and success. Similarly, deworming programs may play a big role in alleviating poverty in countries affected by intestinal worms.
