NCT ID NCT05154331
First seen Aug 21, 2026 ยท Last updated Aug 21, 2026
Summary
This study is a large household survey in Lusaka, Zambia, that will follow thousands of women of reproductive age over time. The goal is to accurately measure pregnancy rates and outcomes, including live births, stillbirths, and infant deaths. Researchers will also collect information on social, demographic, and health factors to better understand what contributes to complications during pregnancy and after birth. The findings could help shape future programs to improve maternal and infant health.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- This research could identify factors that contribute to pregnancy complications and infant deaths, potentially guiding future public health strategies to improve maternal and child health in similar settings.
- What could go wrong
- As an observational survey, it cannot prove cause and effect. The findings may be specific to Lusaka and may not apply to other regions. Data collection relies on self-reporting, which can be inaccurate.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
We will initially obtain verbal consent from the head of household (HoH), defined as an available adult (\> 18 years old) who is able to provide information about household composition for pre-screening purposes. We will then identify potentially eligible women of reproductive age within each household and invite them to complete study screening procedures. Women of reproductive age eligibility criteria Inclusion criteria: * Verbal consent obtained from head-of-household * 15-49 years of age and a member of household in the catchment area * Willing and able to provide written informed consent or assent with next-of-kin consent * Willing to undergo study procedures Exclusion criteria: Any other condition (social or medical) that, in the opinion of the study staff, would make participation unsafe or complicate data interpretation. Study staff may note physical, psychological, or social conditions not explicitly stated in the eligibility criteria that could make some women poor candidates for study participation.
