Abstract
Background
Obesity is on the rise globally in adults and children, including in tropical areas where diseases such as dengue have a substantial burden, particularly in children. Obesity impacts risk of severe dengue disease; however, the impact on dengue virus (DENV) infection and dengue cases remains an open question.
Methods
We used 9 years of data from 5940 children in the Pediatric Dengue Cohort Study in Nicaragua to determine whether pediatric obesity is associated with increased susceptibility to DENV infection and symptomatic presentation. Analysis was performed using generalized estimating equations adjusted for age, sex, and preinfection DENV antibody titers.
Results
From 2011 to 2019, children contributed 26 273 person-years of observation, and we observed an increase in prevalence of overweight (from 12% to 17%) and obesity (from 7% to 13%). There were 1682 DENV infections and 476 dengue cases in the study population. Compared with participants with normal weight, participants with obesity had higher odds of DENV infection (adjusted odds ratio [aOR], 1.21; 95% confidence interval [CI]: 1.03–1.42) and higher odds of dengue in DENV-infected individuals (aOR, 1.59; 95% CI: 1.15–2.19). Children with obesity infected with DENV showed increased odds of presenting fever (aOR, 1.46; 95% CI: 1.05–2.02), headache (aOR, 1.51; 95% CI: 1.07–2.14), and rash (aOR, 2.26; 95% CI: 1.49–3.44) when compared with children with normal weight.
Conclusions
Our results indicate that obesity is associated with increased susceptibility to DENV infection and dengue cases in children, independent of age, sex, and preinfection DENV antibody titers.
