Hypothesis

What is the prevalence of sexually transmitted infections (STIs) in pregnant women and their association with adverse birth outcomes in Malawi?

Conclusion

The study found that STIs, particularly HIV, Neisseria gonorrhoeae, and untreated syphilis, are prevalent among pregnant women in Malawi and are associated with adverse birth outcomes.

Supporting Evidence

  • HIV prevalence was 16.5% among participants.
  • Maternal prevalence of Neisseria gonorrhoeae was 3.1%.
  • Maternal prevalence of untreated syphilis was 2.0% for early stage.
  • Adverse birth outcomes were more common among women with untreated syphilis.
  • NG positivity significantly increased the odds for adverse birth outcomes.

Takeaway

Pregnant women in Malawi often have infections that can harm their babies, but many don't show symptoms. Testing for these infections can help keep both moms and babies healthy.

Methodology

A case-control study was conducted where maternal vaginal swabs were tested for STIs, and associations with adverse birth outcomes were analyzed.

Potential Biases

Potential bias due to self-reported data and the refusal of women to participate based on personal beliefs.

Limitations

Poor recruitment due to many eligible women declining to participate, and the study was conducted at a single hospital, which may not represent the broader population.

Participant Demographics

The study included pregnant women who delivered at Queen Elizabeth Central Hospital, with a median age of 24 years.
