Distance to public test sites and HIV testing

Area of Science:

• Public Health
• Health Services Research
• Epidemiology

Background:

• HIV testing is crucial for disease control and prevention.
• Access to testing services can be influenced by geographical and socioeconomic factors.
• Low-income populations often face barriers to healthcare access, including HIV testing.

Purpose of the Study:

• To investigate the relationship between the proximity of publicly funded HIV testing sites and HIV testing uptake.
• To determine how distance to public testing facilities affects testing behavior among different socioeconomic groups in Los Angeles County.

Main Methods:

• Utilized multinomial logit models to analyze data from 5,361 Los Angeles County adults.
• Simultaneously estimated the likelihood of obtaining an HIV test and the type of testing location used (private physician, public clinic, nonmedical setting).
• Examined the impact of distance to the nearest publicly funded test site on testing behavior.

Main Results:

• Low-income Los Angeles residents demonstrated a reduced likelihood of using publicly funded HIV testing sites when they were more distant.
• Increased distance to public testing sites was associated with lower overall HIV testing rates among the poor.
• Distance to public testing sites did not significantly affect HIV testing rates among non-poor individuals.

Conclusions:

• Geographic accessibility of publicly funded sites is a critical determinant of HIV testing for low-income populations.
• To increase HIV testing rates, particularly in populations with rising HIV prevalence, public health initiatives must prioritize minimizing the time and financial costs associated with testing.
• Strategies to improve access, such as increasing the number or availability of conveniently located public testing sites, are essential.
