Influence of Obesity Diagnosis With Organ Dysfunction, Mortality, and Resource Use Among Children Hospitalized With...

Area of Science:

• Pediatric critical care medicine
• Infectious diseases
• Public health and epidemiology

Background:

• Sepsis, a life-threatening response to infection, is a leading cause of child mortality.
• Obesity is associated with chronic inflammation, but its impact on pediatric infection and sepsis is not well understood.
• Understanding obesity's role in pediatric infections is crucial for improving patient outcomes.

Purpose of the Study:

• To investigate the association between obesity and outcomes in children hospitalized with infection.
• To evaluate the impact of obesity on organ dysfunction, mortality, hospital stay duration, and charges.
• To explore how illness severity modifies these associations.

Main Methods:

• Retrospective analysis of a national dataset (2009 Kids' Inpatient Database).
• Inclusion of hospitalizations for children aged 0 to 20 years with infection.
• Comparison of outcomes between obese and non-obese pediatric patients.

Main Results:

• Obese children hospitalized for infection experienced higher rates of organ dysfunction (7.35% vs. 5.5%).
• Obese patients had significantly longer hospital stays (4.1 vs. 3.5 days) and higher medical charges (US$29,019 vs. US$21,200).
• While in-hospital mortality did not differ by obesity status, illness severity influenced organ dysfunction, hospital stay, and charges.

Conclusions:

• Obesity in hospitalized children with infection is associated with increased organ dysfunction, longer stays, and higher costs, but not mortality.
• Illness severity plays a key role in mediating the relationship between obesity and these adverse outcomes.
• Findings highlight the need for targeted strategies to manage obesity's impact on pediatric infections and sepsis.
