Popis: Objective: This study aimed to investigate human adenovirus 36 (Adv36) as an associated factor for adiposity in children and adolescents aged 9–12 years. Methods: This was a case-control study comparing overweight (cases) and eutrophic (controls) children and adolescents aged 9–12 years based on their body mass index in relation to human adenovirus 36 serology. Human adenovirus 36-specific neutralizing antibodies were assessed using the serum neutralization assay, and a questionnaire regarding the subjects’ personal backgrounds, breastfeed history, age of starting daycare, and eating and exercise habits was also applied. Results: A total of 101 (51, eutrophic; 50, overweight) children were included in the study. The Adv36 seropositivity rate was of 15.8%, which increased the chance of being overweight by 3.17 times (p = 0.049). Enrollment in a full-time daycare center before the age of 24 months increased the chance of being overweight by 2.78 times (p = 0.027). Metabolic parameters (total cholesterol and blood glucose) were insignificantly different among children who were seropositive or seronegative for human adenovirus 36. Conclusion: This study concluded that excessive weight was positively associated with seropositivity for human adenovirus 36. Early enrollment in a full-time daycare was also an associated factor for obesity. Such data, confirmed in new studies, reinforces the role of human adenovirus 36 in the increase of childhood adiposity.
