Oral health intervention for improving overall health status of children living with HIV in Cambodia

Abstract Background: Oral health status is known to be associated with overall health among people living with HIV. However, it is unclear whether dental caries is associated with viral load among this population. In particular, dental caries among children living with HIV needs to be better understood, as this can affect their overall health and well-being in future. This study assessed the association between dental caries and viral load among children living with HIV in Phnom Penh, Cambodia. Methods: This cross-sectional study was conducted at the National Paediatric Hospital as a baseline survey of a randomized controlled trial. The study population included children living with HIV aged 3–15 years and their primary caregivers. We collected data on the children’s oral health status by oral examination and the latest HIV viral load data stored in the patients’ information system of the hospital. Multiple logistic regression analysis was conducted to assess association between dental caries and viral load. The cut-off point of undetectable viral load was set at <40 copies/mL. Results: Data from 328 children were included in the analyses. Moreover, 68.3% had an undetectable viral load. The mean number of permanent or deciduous teeth with caries was 7.7 (standard deviation [SD], 5.0). In the regression analysis, dental caries in permanent or deciduous teeth were positively associated with detectable viral load (adjusted odds ratio [AOR]: 1.07, 95% confidence interval [CI]: 1.01, 1.14). Having received antiretroviral therapy ≥1 year and self-reported excellent adherence to the antiretroviral drug were also negatively associated with detectable viral load. Among children with detectable levels of viral load, dental caries in permanent or deciduous teeth were also positively associated with non-suppression of viral load (>1000 copies/mL) (AOR: 1.12, 95% CI: 1.03, 1.23). Conclusions: Dental caries was associated with viral load status detection among children living with HIV. This finding suggests that oral health status may affect the immune status of the children. Oral health of children living with HIV should be strengthened, and further research is needed to clarify the causal relationship between viral load and oral health status.
