Food insecurity and CD4% Among HIV+ children in Gaborone, Botswana

Area of Science:

• Pediatric HIV/AIDS research
• Global public health
• Nutrition and immunology

Background:

• Household food insecurity (HFI) poses a significant challenge to child health in Sub-Saharan Africa.
• Understanding factors affecting immune recovery, such as CD4% (a measure of immune system health), is crucial for pediatric HIV management.
• Limited research exists on the specific impact of HFI on immunological markers in young HIV-positive children in Botswana.

Purpose of the Study:

• To examine the association between household food insecurity (HFI) and CD4% in HIV-positive children aged 2-6 years.
• To identify potential factors that influence immune status in pediatric HIV patients in Botswana.

Main Methods:

• A cross-sectional study involving 78 HIV-positive outpatients aged 2-6 years at the Botswana-Baylor Children's Clinical Center of Excellence.
• Household food insecurity (HFI) was measured using a validated survey instrument.
• Multiple linear regression analysis was employed to assess the relationship between HFI and CD4%, controlling for sociodemographic and clinical variables.

Main Results:

• A significant negative association was found between household food insecurity (HFI) and CD4% (beta = -0.6, 95% CI: -1.0 to -0.1).
• Child gender also showed a significant effect on CD4% (beta = 5.6, 95% CI: 1.3 to 9.8).
• These findings indicate that food insecurity may impair immune status in this pediatric cohort.

Conclusions:

• Household food insecurity (HFI) is a significant factor associated with lower CD4% in young HIV-positive children in Botswana.
• Interventions aimed at alleviating food insecurity could potentially enhance immune recovery and improve clinical outcomes for pediatric HIV patients.
• These findings highlight the importance of integrated approaches addressing both nutritional and medical needs in managing pediatric HIV in resource-limited settings.
