Insights
Higher body mass index was not associated with increased disease severity or poorer outcomes in children with acute respiratory distress. This study found no significant differences in illness severity or clinical outcomes between obese and non-obese pediatric patients.
Area of Science:
- Pediatric critical care medicine
- Obesity and health outcomes
- Respiratory failure research
Background:
- Childhood obesity is a growing concern with potential health implications.
- Understanding the impact of body mass index on acute illnesses in children is crucial for effective treatment.
Purpose of the Study:
- To investigate the association between elevated body mass index (BMI) and the severity of acute respiratory distress and failure in pediatric patients.
- To determine if obesity independently influences morbidity and mortality in children hospitalized for respiratory emergencies.
Main Methods:
- A retrospective cross-sectional study was conducted on pediatric patients (2-20 years) admitted for acute respiratory distress or failure.
- Disease severity was measured using the respiratory component of the Pediatric Early Warning Score (PEWS) adjusted for altered mental status (Resp-PEWS + AMS).
- Outcomes assessed included hospital and intensive care unit length of stay (LOS) and mortality.
Main Results:
- Obese children constituted 13% of the study cohort (42/334).
- No significant differences were observed in Resp-PEWS + AMS scores between obese and non-obese children.
- Hospital LOS, intensive care LOS, and mortality did not differ significantly between the groups, even after multivariate analysis.
Conclusions:
- Body habitus, specifically obesity, was not found to be an independent predictor of illness severity in pediatric patients with acute respiratory distress and failure.
- Clinical outcomes, including length of stay and mortality, were not significantly impacted by obesity in this cohort.
Aim:
The purpose of this study was to assess for an association between higher body mass index and disease severity, morbidity and mortality in children admitted for an acute respiratory distress and failure.
Methods:
A single-institution retrospective cross-sectional study performed in the United States evaluating paediatric patients, 2-20 years of age, admitted for diagnoses related to acute respiratory distress and acute respiratory failure. Main outcomes include disease severity as assessed using the respiratory component of the Paediatric Early Warning Score (PEWS) with adjustment for altered mental status (Resp-PEWS + AMS), hospital or intensive care length of stay (LOS) and death.
Results:
Children with obesity made up 42/334 (13%) of the cohort. There was no significant difference in Resp-PEWS + AMS between obese and non-obese cohorts (mean of 0.93, {standard deviation 1.11} vs. 1.13 {1.35}, range 0-6, rank sum p = 0.46). There was no significant difference in overall hospital LOS or intensive care LOS. Multivariate analysis including diagnosis as a control variable did not change the results.
Conclusion:
We found that body habitus was not an independent factor for illness severity or clinical outcomes.
