Impulse oscillometry and obesity in children

Abstract

Obese children showed increased oscillometry parameters values representative of airway obstruction, compared to normal-weight children. Changes in some oscillometry parameters can already be observed in overweight school-aged children.

Lung function in obese children and adolescents without respiratory disease: a systematic review

“…A wide age range (5 to 18 years) could be observed in the studies, with a higher prevalence between 11 and 13 years, which was an inclusion criterion in 69.7% (23/33) of the articles [ 11 , 13 – 15 , 17 – 22 , 24 – 27 , 29 , 30 , 32 , 33 , 35 , 36 , 38 – 40 ].…”

“…The articles included were produced in 18 countries, with a predominance of European (8) [ 21 – 23 , 31 , 34 , 35 , 40 ], South American (8) [ 17 , 18 , 26 , 32 , 33 , 37 , 39 , 41 ] and Asian (7) [ 11 , 13 , 15 , 27 , 30 , 31 , 42 ] countries. Also, 4 studies from North America were included [ 19 , 24 , 38 , 43 ], as well as one from Central America [ 29 ], one from Oceania [ 20 ] and four from intercontinental countries ( three Euroasians [ 14 , 25 , 36 ] and one from Asia and Oceania [ 12 ]).…”

“…There was no uniform definition of obesity among studies: 27.3% (9/33) [ 11 , 14 , 15 , 20 , 35 – 37 , 40 , 42 ] used references by Cole et al [ 45 – 47 ]; 21.2% (7/33) [ 12 , 17 , 19 , 26 , 29 , 38 , 43 ] used the criteria established by the Center for Disease Control and Prevention (CDC); 15.1% (5/33) [ 13 , 18 , 33 , 39 , 41 ] used the definition of the World Health Organization (WHO); 12.1% (4/33) [ 16 , 24 , 32 , 34 ] did not mention any references for the definition of obesity; and 27.3% (9/33) [ 14 , 21 – 23 , 25 , 27 , 28 , 31 , 36 ] used references according to their countries of origin. Two [ 14 , 36 ] of the studies mentioned above, used references by Cole et al [ 45 – 47 ] in addition to references according to their countries of origin.…”

“…The group with individuals with overweight presented higher value than the control group for % of predicted value of R5, Fres and AX and for absolute Fres Children with obesity had higher IOS value, which represents obstruction of the airway in comparison with children with normal weight. Some changes occurred among children with overweight Cibella et al [ 33 ] (2015) - Italy To investigate the effects of weight on lung function of healthy children in a sample registered in 2 cross-sectional surveys with selected age group Yes (history of wheezing, night cough or cough due to exercise) Cross-sectional 2,393 Caucasian individuals aged 10 to 17 years (51.1% boys) Spirometry (Microloop, Miro Medica, Chatham Maritime, Kent, UK) ATS and ERS - position not mentioned FVC, FEV 1 , FEV 1 /FVC, FEF 25–75% , FEF 25–75% /FVC In the control of the variables weight, height, age and sex in the multiple linear regression, the weight B coefficient was (+) for FVC and FEV 1 , being higher for FVC, and (−) for FEV 1 /FVC and FEF 25–75% /FVC. In the division by age group (< 11, 12, 13 and > 14 years), there was a (+) association of the B weight coefficient with FVC and FEV 1 and a (−) association with FEV 1 /FVC and FEF 25–75% /FVC (association of FEF 25–75% and B weight coefficient did not occur in the group < 11 years).…”

Therapeutic Blowing Toys: Does the Overlap of Ventilatory Stimuli Alter the Respiratory Mechanics of Healthy Schoolchildren?

“…Also regarding the sample, it is relevant to justify the presence of obese children, since altered IOS parameters were identified in this population. 23 Children with this profile were kept in the sample because they were compatible with the inclusion criteria and values within the normal range, according to reference values for Brazilian children. 9 It should be noted that this study is characterized by having a convenience sample, in which two children (11 and 13 years old), upon performing spirometry, showed altered values and were excluded.…”
