Insights
Obesity in critically ill children was linked to less need for intubation and inotropic support. However, overweight or obese status did not impact mortality or mechanical ventilation duration in pediatric intensive care unit patients.
Area of Science:
- Pediatric Critical Care Medicine
- Pediatric Obesity Research
- Clinical Outcomes in Pediatrics
Background:
- The 'obesity paradox' suggests obesity may be protective in critically ill adults.
- Limited data exists on obesity's effect in critically ill pediatric populations.
- Understanding weight status impact is crucial for pediatric intensive care unit (PICU) management.
Purpose of the Study:
- To investigate if obesity offers a protective effect in critically ill children.
- To compare outcomes between normal weight, overweight, and obese pediatric patients in the ICU.
- To determine the association of weight status with mortality, intubation, and support needs.
Main Methods:
- Retrospective cohort study of 1817 pediatric patients (aged 2-18 years) admitted to a PICU.
- Patients categorized by body mass index (BMI) into normal weight, overweight, and obese groups.
- Outcomes analyzed: mortality, need for intubation, inotropic support, and mechanical ventilation duration.
Main Results:
- Overweight and obese pediatric patients showed a significantly lower requirement for intubation and inotropic support compared to normal-weight peers.
- No significant difference in mortality rates was observed across weight categories.
- Duration of mechanical ventilation did not differ between normal weight, overweight, and obese pediatric patients.
Conclusions:
- In critically ill children, being overweight or obese is associated with a reduced need for intubation and inotropic support.
- Overweight and obesity status were not found to be protective or a risk factor for mortality in this pediatric cohort.
- Findings suggest weight status influences specific interventions but not overall survival or ventilation duration in critically ill children.
Purpose:
To examine whether obesity confers a protective effect on critically ill pediatric patients, similar to what has been reported in critically ill adults.
Methods:
A retrospective cohort study including patients aged 2-18 years admitted to a 24-bed pediatric intensive care unit from 2009 to 2014. Patients were divided into 1 of 3 weight categories: normal weight (body mass index [BMI], 5%-84.9%), overweight (BMI, 85%-94.9%), and obese (BMI ≥95%). Outcomes investigated included mortality, need for intubation, need for inotropic support, and duration of mechanical ventilation.
Results:
A total of 1817 patient encounters met inclusion criteria. There was no difference in Pediatric Index of Mortality 2 scores between groups. There was a significantly smaller percentage of overweight and obese patients requiring intubation ( P = .003) and inotropic support ( P = .031) compared with normal-weight patients. Being overweight or obese was neither protective nor a risk factor for mortality with an adjusted odds ratio of 1.83 (confidence interval [CI], 0.82-3.85; P = .12) and 1.51 (CI, 0.70-3.12; P = .27) comparing the overweight and obese groups with the normal-weight group, respectively. There was no difference in duration of mechanical ventilation between the normal-weight and overweight and obese groups ( P = .893 and 0.484, respectively).
Conclusions:
In critically ill pediatric patients, being overweight or obese was associated with decreased need for intubation and inotropic support compared with normal-weight patients. However, being overweight or obese is neither protective nor a risk factor for mortality or duration of mechanical ventilation.
