Hypothesis
What is the prevalence of chlamydia, gonorrhoea, and trichomoniasis among general populations in sub-Saharan Africa over time?
Conclusion
The study found a high and geographically varied prevalence of STIs in sub-Saharan Africa, with chlamydia prevalence increasing over time.
Supporting Evidence
- Chlamydia prevalence increased by 34.5% from 2010 to 2020 in SSA.
- Gonorrhoea and trichomoniasis trends were not statistically significant.
- Male-to-female prevalence ratios differed from existing global ratios.
Takeaway
This study looked at how common certain infections are in Africa and found that more people are getting chlamydia, especially in some areas.
Methodology
The study conducted a systematic review and meta-regression analysis of STI prevalence data from 211 studies across 28 countries.
Potential Biases
Potential overestimation of STI prevalence due to reliance on specific populations like ANC attendees.
Limitations
The study was limited by sparse and heterogeneous data, particularly among men and in Central Africa.
Participant Demographics
Most studies focused on females (82.5%) and included participants aged 12 years and older.
Statistical Information

Confidence Interval
95% CI: 5.0–8.2% for chlamydia among females
Statistical Significance
p<0.05
