Robson LS, Abulimiti A, Granados JZ, Zia AN, Balmain BN, Pawelczyk JA, Babb TG. Pediatric patients diagnosed as overweight and obese have an elevated risk of dyspnea. Respir Physiol Neurobiol 2024; 323:104230. [PMID: 38340972 PMCID: PMC10947832 DOI: 10.1016/j.resp.2024.104230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 01/28/2024] [Accepted: 02/02/2024] [Indexed: 02/12/2024]
Abstract
We investigated whether pediatric patients with overweight and obesity are more likely to have dyspnea compared with those who are non-overweight. We collected de-identified data from TriNetX, a global federated multicenter research database, using both the UT Southwestern Medical Center and multinational Research Networks. Our analysis focused on patients aged 8-12 years. We identified overweight and obesity using ICD-10-CM codes E66 and dyspnea using code R06.0. Patients with overweight and obesity had a significantly higher risk of dyspnea compared with those who were non-overweight. This association was observed in both the UT Southwestern Network (risk ratio: 1.81, p < 0.001) and the Research Network (risk ratio: 2.70, p < 0.001). Furthermore, within the UT Southwestern Network, the risk was found to be higher in females compared with males (risk ratio: 2.17 vs. 1.67). These results have significant clinical implications, suggesting that clinicians should consider overweight and obesity as independent risk factors for dyspnea in pediatric patients after excluding other possible contributing factors.

[PMID: 38143516 PMCID: PMC10748557 DOI: 10.1177/2333794x231220873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 11/21/2023] [Accepted: 11/29/2023] [Indexed: 12/26/2023] Open
Abstract
Objective. To describe the impact of weight on length of stay (LOS) and oxygen requirement among hospitalized children with COVID-19. Methods. This is a retrospective review of 153 children admitted for COVID-19 from March 2020 to October 2021. Body mass index (BMI) percentile and weight-for-age (WFA) percentile were used to determine weight status for children ≥2 years and <2 years respectively. Results. We found 2 distinct patterns for patients <2 years and ≥2 years; The likelihood of needing oxygen and LOS ≥ 5 days was higher for children ≥2 years with BMI ≥ 85th percentile (P = .0415 and P = .0197). Among those <2 years, mean WFA percentile decreased with increasing oxygen need (P = .0325). There was a negative correlation between LOS and WFA percentile (r = -.31, P = .0123). Conclusion. It is important to stratify patients' risk according to their age, BMI and WFA percentile during hospitalization for COVID 19.

Obesity as a risk factor for severe influenza infection in children and adolescents: a systematic review and meta-analysis. Eur J Pediatr 2023; 182:363-374. [PMID: 36369400 PMCID: PMC9652042 DOI: 10.1007/s00431-022-04689-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Revised: 10/30/2022] [Accepted: 11/01/2022] [Indexed: 11/13/2022]
Abstract
UNLABELLED Obesity has been recently identified as a predisposing factor for a worse prognosis in viral illnesses such as SARS-CoV-2; however, its role in children with influenza is not yet clarified. The current systematic review and meta-analysis aims to assess whether obesity is a risk factor for either hospitalization or a worse prognosis when hospitalized among children infected by influenza. We systematically searched the following databases using a structured algorithm: MEDLINE, Clinicaltrials.gov, and Cochrane Central Register of Controlled Trials (CENTRAL). Statistical meta-analysis was performed using the "meta" package in R software, and included studies were evaluated using the Newcastle-Ottawa scale. Among children with influenza, obesity increased the odds of hospitalization with a pooled OR of 1.89 (95% CI [1.23, 2.9], I2 = 0, p = 0.003). When hospitalized, children with obesity were also more likely to have a worse outcome than their healthy-weight counterparts, with a pooled OR of 1.24 (95% Cl [1.02; 1.51], I2 = 11, p = 0.03). In an effort to lower heterogeneity, a leave-one-out meta-analysis was conducted. Publication bias was assessed with the visual inspection of funnel plots and the trim-and-fill method. Certainty assessment was evaluated using the GRADE score. CONCLUSIONS The findings of our meta-analysis suggest that obesity in children with influenza is associated with a worse prognosis, both hospitalization and ICU admission/death. WHAT IS KNOWN • Obesity has been identified as a risk factor for non-communicable as well as communicable diseases. • A previous meta-analysis failed to demonstrate a statistically significant association between obesity and influenza infection severity. WHAT IS NEW • Children with high BMI and influenza infection are more likely to get hospitalized. • Pediatric inpatients with increased BMI and influenza infection may have a worse prognosis.

Respiratory Muscle Interval Training Improves Exercise Capacity in Obese Adolescents during a 3-Week In-Hospital Multidisciplinary Body Weight Reduction Program. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 20:487. [PMID: 36612808 PMCID: PMC9819313 DOI: 10.3390/ijerph20010487] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 12/20/2022] [Accepted: 12/23/2022] [Indexed: 06/17/2023]
Abstract
The purpose of this study was to determine whether a novel approach of interval training targeted to the respiratory muscles (RMIT; normocapnic hyperpnea with resistance) in addition to a multidisciplinary in-hospital body weight reduction program (BWRP) was able to improve the integrative response to exercise in young patients with obesity. Nine male patients (17.9 ± 4.9 (x ± SD) years; 113.8 ± 16.3 kg) underwent 12 sessions of RMIT and eight age-and sex-matched patients underwent 12 sessions of a sham protocol (CTRL) during the same 3-week BWRP. Before and after the interventions the patients performed an incremental and a heavy-intensity constant work-rate (CWR>GET) cycling exercise to voluntary exhaustion. Body mass decreased by ~4.0 kg after both RMIT (p = 0.0001) and CTRL (p = 0.0002). Peak pulmonary O2 uptake (V˙O2) increased after RMIT (p = 0.02) and CTRL (p = 0.0007). During CWR>GET at ISO-time, V˙O2 (p = 0.0007), pulmonary ventilation (p = 0.01), heart rate (p = 0.02), perceived respiratory discomfort (RPER; p = 0.03) and leg effort (p = 0.0003) decreased after RMIT; only RPER (p = 0.03) decreased after CTRL. Time to exhaustion increased after RMIT (p = 0.0003) but not after CTRL. In young patients with obesity, RMIT inserted in a 3-week BWRP reduced the cardiorespiratory burden, the metabolic cost, the perceived effort, and improved exercise tolerance during heavy-intensity cycling.

Abstract
The purpose of the present study was to investigate changes in the energy cost of locomotion during walking (Cw) related to changes in body mass (BM, kg) and body composition in adolescents with obesity. Twenty-six (12 boys and 14 girls) obese adolescents (mean: body mass index, 33.6 ± 3.7 kg·m-2; 42.7 ± 4.5% fat mass (FM)) followed a 9-month multidisciplinary inpatient weight-reduction program consisting of lifestyle education, moderate energy restriction, and regular physical activity in a specialised institution. At baseline (M0), the end of the 9-month program (M9), and after the 4-month follow-up (M13), oxygen consumption and carbon dioxide production of the standardised activity program were assessed by whole-body indirect calorimetry over 24 hours, and body composition was assessed by dual-energy X-ray absorptiometry. At M9, adolescents showed an 18% reduction in BM (p < 0.001) and 40% in total FM, while fat-free mass (kg) remained stable in boys but decreased by ∼6% in girls (p = 0.001). Similarly, the mean Cw decreased by 20% (p < 0.001). At M13, BM, FM, and Cw were slightly higher compared with at M9. In conclusion, moderate energy restriction and regular moderate physical activities improved walking economy, improved exercise tolerance, and induced beneficial changes in the body composition of adolescents with obesity. Novelty: Reduction of FM in the trunk region, and consequently reducing the work carried out by respiratory muscles, contributes to reducing Cw in adolescents with obesity. A lower walking cost can be effective in improving exercise tolerance and quality of life in obese adolescents.
