Abstract
Objective To examine the effects of socioeconomic and demographic conditions on the prevalence of preterm birth in a local community. Methods Pregnant women (aged ≥16 years) willing to provide informed consent in one of the two languages of the community were recruited in South Africa between August 2007 and January 2015. Specifically designed case report forms collected information and measurements prospectively. Results After reviewing the medical records of 5806 women, it was possible to identify those who had spontaneous preterm birth (SPTB), induced preterm birth (IPTB), or spontaneous term birth (STB). Women with IPTB (vs SPTB) were more obese and had higher education levels and household incomes; more had telephones and running water at home. They enrolled earlier and more developed hypertension and pre‐eclampsia. Women with SPTB (vs STB) were less obese, shorter, had smaller arm circumferences and higher gravidities and Edinburgh Depression Scores, lower education, fewer telephones, and less running water at home. More women with SPTB used methamphetamine, cigarettes, and were heavier smokers. Conclusion SPTB and IPTB should not be conflated. Programs to reduce the high prevalence of SPTB should include improving education, lifestyle, and socioeconomic conditions. Addressing hypertension should help reduce preterm inductions.Funding Information
