Kapuš O, Fellnerová I, Chaloupková P, Martišová K. Relationship between body composition and pulmonary function in healthy adolescents. Pediatr Int 2022; 64:e15114. [PMID: 35704449 DOI: 10.1111/ped.15114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 12/20/2021] [Accepted: 12/27/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND It has been long established that body composition affects pulmonary function but little attention has been given to assessing lung function in healthy adolescents and determining the influence of body composition on these variables. METHODS We measured 399 boys (mean age 16.7 ± 1.2 years) and 46 girls (mean age 17.1 ± 1.2 years). We used multi-frequency segmental bioimpedance analyzer Tanita MC 980-MA Plus for body composition parameters and Micro Direct MicroGP Spirometer MS07 for spirometry parameters. RESULTS Mean body height was 179.5 cm and mean body mass index was 22.5 kg/m2 in boys. In girls, mean body height was 166.9 cm and body mass index was 22.5 kg/m2 . After adjusting for age, body height, bodyweight, and smoking status, we found a significant (P = 0.01) association (β = 0.35-0.43) between forced vital capacity and fat-free mass (FFM) or trunk fat-free mass only in boys. Similarly, body fat mass (BFM) showed significant (P = 0.01) negative association (β = -0.29 to -0.20) with spirometry parameters only in boys. In girls, the results showed a similar trend but it was not significant. CONCLUSIONS In conclusion, FFM or trunk FFM is more closely related to lung capacity than BFM or trunk BFM after adjustment for confounding variables in healthy adolescent boys. Body height explained up to 23% variability of forced vital capacity and fat-free mass explained up to 27% in a linear regression model.

Ferreira MS, Marson FAL, Wolf VLW, Ribeiro JD, Mendes RT. Lung function in obese children and adolescents without respiratory disease: a systematic review. BMC Pulm Med 2020; 20:281. [PMID: 33115462 PMCID: PMC7594270 DOI: 10.1186/s12890-020-01306-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2019] [Accepted: 10/01/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Obesity in children and adolescents is associated with increased morbidity and mortality due to multisystemic impairment, including deleterious changes in lung function, which are poorly understood. OBJECTIVES To perform a systematic review to assess lung function in children and adolescents affected by obesity and to verify the presence of pulmonary changes due to obesity in individuals without previous or current respiratory diseases. METHODS A systematic search was performed in the MEDLINE-PubMed (Medical Literature Analysis and Retrieval System Online), Embase (Excerpta Medica Database) and VHL (Virtual Health Library/Brazil) databases using the terms "Lung Function" and "Pediatric Obesity" and their corresponding synonyms in each database. A period of 10 years was considered, starting in February/2008. After the application of the filters, 33 articles were selected. Using the PICOS strategy, the following information was achieved: (Patient) children and adolescents; (Intervention/exposure) obesity; (Control) healthy children and adolescents; (Outcome) pulmonary function alterations; (Studies) randomized controlled trial, longitudinal studies (prospective and retrospective studies), cross-over studies and cross-sectional studies. RESULTS Articles from 18 countries were included. Spirometry was the most widely used tool to assess lung function. There was high variability in lung function values, with a trend towards reduced lung function markers (FEV1/FVC, FRC, ERV and RV) in obese children and adolescents. CONCLUSION Lung function, measured by several tools, shows numerous markers with contradictory alterations. Differences concerning the reported results of lung function do not allow us to reach a consensus on lung function changes in children and adolescents with obesity, highlighting the need for more publications on this topic with a standardized methodology.

Abstract
Objective: To analyze the peak expiratory flow (PEF) in obese subjects in standing (ST), seated (SE), supine (SU), prone (PR), and right and left lateral decubitus (RL and LL) positions. Methods: 36 obese volunteers, aged between 18 and 54 years, and nonsmokers, were evaluated by anthropometric data; spirometry; international physical activity questionnaire (IPAQ); and PEF in ST, SE, SU, PR, RL, and LL positions, randomly. Results: The mean age was 27.3 ± 7.4 years and BMI of 38.7 ± 3.2 kg/m2; IPAQ results: active (50%), irregularly active (25%), very active (16.7%), and sedentary (08.3%); spirometry results: FVC = 100.33%, FEV1 = 92.83%, FEV1/FVC ratio = 0.95, FEF25-75% = 85.55%. The PEF (L/min) were within the normal range and there was no difference between the ST and SE (428.6 ± 100.9 and 430.0 ± 100.1). Comparing ST and SE to the other positions, in absolute and percent of predicted values (L/min and %), there was a decrease in the SU (85.4 ± 14.9), PR (401.1 ± 92.4 and 84.1 ± 14.4), RL (398.6 ± 94.7 and 83.3 ± 14.9) (p < 0.05), and there was no difference to SU (409.4 ± 102.8) and LL (410.3 ± 93.9 and 85.8 ± 14.5). Conclusion: The PEF of healthy obese are similar in the standing and seated positions. The PEF decreases in the lying positions, except for the LL, that could be used as an alternative for measurements.

Abstract
OBJECTIVE To assess the effects of obesity on lung volume and capacity in children and adolescents. DATA SOURCE This is a systematic review, carried out in Pubmed, Lilacs, Scielo and PEDro databases, using the following Keywords: Plethysmography; Whole Body OR Lung Volume Measurements OR Total Lung Capacity OR Functional Residual Capacity OR Residual Volume AND Obesity. Observational studies or clinical trials that assessed the effects of obesity on lung volume and capacity in children and adolescents (0-18 years) without any other associated disease; in English; Portuguese and Spanish languages were selected. Methodological quality was assessed by the Agency for Healthcare Research and Quality. DATA SYNTHESIS Of the 1,030 articles, only four were included in the review. The studies amounted to 548 participants, predominantly males, with sample size ranging from 45 to 327 individuals. 100% of the studies evaluated nutritional status through BMI (z-score) and 50.0% reported the data on abdominal circumference. All demonstrated that obesity causes negative effects on lung volume and capacity, causing a reduction mainly in functional residual capacity in 75.0% of the studies; in the expiratory reserve volume in 50.0% and in the residual volume in 25.0%. The methodological quality ranged from moderate to high, with 75.0% of the studies classified as having high methodological quality. CONCLUSIONS Obesity causes deleterious effects on lung volume and capacity in children and adolescents, mainly by reducing functional residual capacity, expiratory reserve volume and residual volume.
