Insights
Childhood obesity is linked to higher healthcare use, including more emergency and outpatient visits. This review highlights the significant impact of excess weight on health service utilization in pediatric populations.
Area of Science:
- Pediatric Health
- Public Health
- Health Services Research
Background:
- Overweight and obesity are significant global health concerns in children.
- Understanding the impact of excess weight on healthcare utilization is crucial for resource allocation and public health planning.
Purpose of the Study:
- To systematically analyze the association between overweight/obesity and health service utilization in children.
- To synthesize findings from observational studies and conduct meta-analyses where data permits.
Main Methods:
- Systematic review and meta-analysis of observational studies published up to May 2020.
- Inclusion criteria: participants ≤19 years, assessment of overweight/obesity impact on healthcare utilization.
- Data sources: PubMed, MEDLINE, CINAHL, EMBASE, Web of Science.
Main Results:
- Thirty-three studies were included, showing a positive association between obesity/overweight and increased healthcare utilization.
- Meta-analysis revealed significantly higher rates of emergency department (ED) visits (RR 1.34) and outpatient visits (RR 1.11) in obese children compared to normal-weight children.
- Overweight children showed slightly higher, non-significant increases in ED and outpatient visits.
Conclusions:
- Childhood obesity is associated with increased healthcare utilization across various measures.
- Future research should explore the influence of ethnicity and obesity-related comorbidities on healthcare utilization in children.
Objective:
This systematic review and meta-analysis aims to systematically analyse the association of overweight and obesity with health service utilisation during childhood.
Data Sources:
PubMed, MEDLINE, CINAHL, EMBASE and Web of Science.
Methods:
Observational studies published up to May 2020 that assessed the impact of overweight and obesity on healthcare utilisation in children and adolescents were included. Studies were eligible for inclusion if the included participants were ≤19 years of age. Findings from all included studies were summarised narratively. In addition, rate ratios (RRs) and 95% CIs were calculated in a meta-analysis on a subgroup of eligible studies.
Outcome Measures:
Included studies reported association of weight status with healthcare utilisation measures of outpatient visits, emergency department (ED) visits, general practitioner visits, hospital admissions and hospital length of stay.
Results:
Thirty-three studies were included in the review. When synthesising the findings from all studies narratively, obesity and overweight were found to be positively associated with increased healthcare utilisation in children for all the outcome measures. Six studies reported sufficient data to meta-analyse association of weight with outpatient visits. Five studies were included in a separate meta-analysis for the outcome measure of ED visits. In comparison with normal-weight children, rates of ED (RR 1.34, 95% CI 1.07 to 1.68) and outpatient visits (RR 1.11, 95% CI 1.02 to 1.20) were significantly higher in obese children. The rates of ED and outpatient visits by overweight children were only slightly higher and non-significant compared with normal-weight children.
Conclusions:
Obesity in children is associated with increased healthcare utilisation. Future research should assess the impact of ethnicity and obesity-associated health conditions on increased healthcare utilisation in children with overweight and obesity.
