Summary

This study follows 4,700 children whose mothers were given vouchers for free or discounted IUDs to prevent unintended pregnancies. Researchers want to see if preventing unplanned births improves children's school performance and family stability. The study is observational and does not test a new drug or treatment.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
