[Changes in HIV testing in Brazil between 1998 and 2005]

Area of Science:

• Public Health
• Epidemiology
• Social Sciences

Background:

• HIV testing is a critical component of HIV prevention and care.
• Understanding trends and disparities in HIV testing is essential for public health interventions.

Purpose of the Study:

• To analyze changes in HIV testing rates in urban Brazil between 1998 and 2005.
• To identify sociodemographic factors associated with HIV testing.
• To examine reasons for testing and counseling adequacy.

Main Methods:

• Cross-sectional studies in urban Brazil (1998, 2005) with representative samples of adults aged 16-65.
• Data collection included sociodemographic, sexual, reproductive, and health characteristics.
• Statistical analysis using Pearson's chi-square and design-based F test.

Main Results:

• HIV testing increased from 20.2% in 1998 to 33.6% in 2005.
• Testing was higher among women aged 25-34, but lower for those with early sexual initiation or multiple partners.
• Increases in testing among men were limited to specific age groups and socioeconomic factors; testing did not rise in high-risk groups.
• Prenatal HIV testing increased for women, while work-related testing decreased for men.
• In 2005, 50% of those tested received inadequate counseling.

Conclusions:

• HIV testing scale-up in Brazil was unequal, benefiting women of childbearing age, adults, and those with higher socioeconomic status.
• While testing rates rose, the expansion did not ensure informed choice or sufficient quality counseling.
• Addressing disparities and improving counseling quality are crucial for effective HIV testing programs.
