Identifying the appropriate comparison group for HIV-infected individuals

Area of Science:

• Gerontology
• Infectious Diseases
• Epidemiology

Background:

• Effective HIV treatment allows individuals to live longer.
• Age-related comorbidities are now the primary cause of illness and death in treated HIV-infected adults.
• Existing research on comorbidity risk in HIV-infected adults yields mixed results.

Purpose of the Study:

• To address the need for valid comparisons between HIV-infected and uninfected adults regarding age-related comorbidities.
• To explore methods for selecting appropriate HIV-uninfected comparison groups from secondary data.

Main Methods:

• Discusses challenges in comparing HIV-infected and uninfected populations.
• Highlights the importance of considering demographic, clinical, and lifestyle factors.
• Proposes using secondary data resources and selection methodologies to form comparison groups.

Main Results:

• Comparisons are threatened by unaddressed differences between HIV-infected and uninfected groups.
• Secondary data offers a potential method to create valid comparison groups.
• Challenges include data source identification, inclusion criteria, measurement error, and inference threats.

Conclusions:

• Valid inferences about age-related comorbidities in HIV require appropriate comparison groups.
• Using secondary data and selection methods is a resource-efficient approach.
• This methodology has inherent limitations that must be acknowledged.
