RESUMO
Background: Many youth saw a rise in body mass index and obesity during the COVID-19 pandemic associated with virtual schooling and a lack of physical exercise options due to lockdown orders. However, the impact of the worldwide COVID-19 pandemic on body mass index in HIV-infected youth on anti-viral therapy has not been studied. Objective: This study examined COVID-19's impact on body mass index in 157 behaviorally acquired and 39 perinatally acquired youth living with HIV. Methods: Retrospective chart analysis was conducted for body mass index records across pre-COVID, COVID, and post-COVID periods. Results: Age and acquired type showed significant associations with increased body mass index. Limitations included missing data and physiological body mass index changes. Conclusion: The perinatally acquired group's body mass index increased by 1.6 during and 2.3 post-pandemic compared to pre-pandemic levels. Longitudinal follow-up of body mass index changes is needed in this vulnerable population.
