Big Data for Reproductive Health (2018-2019)
One-third of women who begin using a modern method of contraception in low-income countries discontinue within the first year, and half within the first two years, putting them at risk for unintended pregnancies as well as maternal morbidity and mortality. The current method of measuring contraceptive discontinuation (quitting, switching and method failure) relies on household surveys collected in five-year intervals through a retrospective monthly contraceptive calendar. This measurement provides a broad overview of discontinuation, but does not show the granular details often needed to develop programs to effect change.
This project team partnered with local and international stakeholders to built a prototype of an online platform that curates freely available, raw data on contraceptive discontinuation from household surveys into a tool that makes higher-resolution inferences possible by members of the family planning community.
Team members also conducted a literature review on the intersection of big data and contraceptive use. Using this research, the team applied two big data methods (neural networks and unsupervised machine learning) to contraceptive calendar data from the Demographic and Health Survey (DHS). The team’s work led to the creation of a “See the Switch” infographic that highlights the frequency of use for various contraception methods.
