Study probes hidden impact of denied pregnancy on child development
NCT ID NCT02867579
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study looks at how pregnancy denial—when a woman is unaware she is pregnant for months—affects the bond between mother and child. Researchers will compare 130 mothers, half with pregnancy denial and half without, using interviews and observations over 20 months. The goal is to understand risks to child attachment and development, and to find factors that may lead to denial.
