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.
