Background: The aim of this paper is to estimate the seroprevalence of Helicobacter pylori infection in the New Zealand population by ethnicity and year of birth.
Methods: A systematic search identified seven studies in New Zealand that reported prevalence of H. pylori infection among 4463 participants.
Objectives: To (i) document the incidence of multiplicity in Nigeria, (ii) compare healthcare utilization during pregnancy and at delivery for singleton and multiple pregnancies (iii)and investigate whether antenatal care modifies the relationship between multiplicity and likelihood of having skilled attendance.
Methods: This observational study was a secondary analysis of the 2008 Nigeria Demographic and Health Survey and included 17,635 women who gave birth to a live infant between 2003 and 2008. Multivariate logistic regression with adjustment for weighting, clustering and confounding was used to investigate associations and look for effect modification.
