HIV testing, risk perception, and behaviour in the British population

Area of Science:

• Public Health
• Epidemiology
• Behavioral Science

Background:

• HIV testing uptake remains a critical public health concern.
• Understanding the interplay between perceived risk, sexual behavior, and testing is essential for effective HIV prevention strategies.

Purpose of the Study:

• To investigate the relationship between HIV risk behaviors, perceived risk, and HIV testing patterns in the British population.
• To identify disparities in HIV testing uptake among different demographic and risk groups.

Main Methods:

• A large-scale, probability sample survey of 13,751 sexually experienced adults (aged 16-74) in Britain.
• Data collected via computer-assisted interviews between 2010-2012, covering sexual behavior, perceived HIV risk, and recent HIV testing history.
• Analysis excluded HIV tests related to blood donation.

Main Results:

• Only 3.5% of men and 5.4% of women reported an HIV test in the past year.
• Higher perceived HIV risk correlated with sexual risk behaviors and testing, yet most high-risk individuals did not test.
• Significant proportions of tested individuals (29.6% men, 39.9% women) were classified as low risk, aligning with normalization policies.

Conclusions:

• A substantial gap exists between perceived HIV risk and actual testing, particularly among key populations like men who have sex with men (MSM) and Black Africans.
• Current HIV testing policies, while normalizing testing, may not adequately reach those most at risk.
• Targeted strategies are crucial to increase HIV testing uptake among high-risk groups and reduce late diagnoses of HIV infection.
