Frontiers in public health·2024

HIV prevalence in pregnant women in Abidjan, Côte d'Ivoire, decreased from 1995-2002. This trend in antenatal HIV testing likely reflects epidemic maturation and successful prevention campaigns.

Area of Science:

  • Public Health
  • Epidemiology
  • Infectious Diseases

Background:

  • Antenatal HIV seroprevalence surveys are crucial for monitoring the HIV epidemic in Africa.
  • Understanding HIV trends in pregnant populations informs prevention strategies.

Purpose of the Study:

  • To analyze HIV prevalence trends among pregnant women attending antenatal clinics in Abidjan, Côte d'Ivoire, between 1995 and 2002.
  • To assess the impact of prevention of mother-to-child transmission (PMTCT) programs on HIV rates.

Main Methods:

  • Prospective study involving HIV testing of pregnant women attending antenatal clinics.
  • Yearly estimation of HIV prevalence from 1995 to 2002.
  • Analysis of prevalence data stratified by age group.

Main Results:

  • A total of 36,442 women were tested for HIV.
  • Overall HIV prevalence declined from 14-15% in 1995-1996 to 11% in 2002.
  • Prevalence decreased significantly in younger women (18-22 years) from 15% to 8%, while older women showed stable or slightly increasing then decreasing trends.

Conclusions:

  • HIV prevalence among pregnant women in Abidjan has shown an overall decreasing trend.
  • This decline may be attributed to the aging of the HIV epidemic and behavioral changes spurred by awareness and prevention campaigns.
  • This study provides valuable insights into HIV epidemiology in a key African urban center.
