Impact of obesity on pulmonary function of preschool children: an impulse oscillometry study.

Background: The increasing global prevalence of obesity poses significant public health problems, as obesity exerts adverse effects on many systems and lung function. However, research on the lung function of preschool children with obesity is limited and inconclusive. In addition, studies specific to obesity indices that influence lung function in young children with obesity are limited.

Longitudinal effects of obesity on pulmonary function in obese children and adolescents.

Background: To investigate the longitudinal effects of obesity on change in lung function after 1 year of follow-up in obese children and adolescents.

Methods: Obese children/adolescents aged 8-15 years with pulmonary function test (PFT) results and recorded anthropometric obesity indices from 1 year earlier for comparison were recruited. Multiple linear regression of change in each lung function parameter was applied to determine the effect of sex, change in body mass index (ΔBMI), change in chest circumference (ΔCC), change in waist circumference (ΔWC), and change in waist circumference-to-height ratio (ΔWC/Ht).

Incidence and risk factors for long COVID in children with COVID-19 pneumonia.

Background And Objective: There are only a few reports of long COVID including pulmonary function in children after COVID-19 pneumonia. We determined the incidence of long COVID and abnormal pulmonary function in those children and identify risk factors.

Methods: This cohort study enrolled children admitted with COVID-19 pneumonia during 2021-2022.

Effect of Threshold Inspiratory Muscle Training on Functional Fitness and Respiratory Muscle Strength Compared to Incentive Spirometry in Children and Adolescents With Obesity: A Randomized Controlled Trial.

Background: To determine the effect of threshold inspiratory muscle training (IMT) on functional fitness and respiratory muscle strength (RMS) compared to incentive spirometry (IS) in children/adolescents with obesity.

Methods: A total of 60 obese children/adolescents aged 8-15 years were randomized into the threshold IMT group ( = 20), the IS group ( = 20), or the control group ( = 20). The IMT group performed 30 inspiratory breaths with the intensity set at 40% of baseline maximal inspiratory pressure (MIP) twice daily for 8 weeks; the IS group performed 30 breaths with sustained maximum inspiration twice daily for 8 weeks; and, the control group was assigned no training device for 8 weeks.

Obesity Indices for Predicting Functional Fitness in Children and Adolescents With Obesity.

We aimed to determine the obesity indices that affect 6-min walk test (6-MWT) distance in children and adolescents with obesity and to compare the 6-MWT distance of obese subjects with that of normal-weight subjects. Obese children and adolescents aged 8-15 years and normal-weight age- and gender-matched controls were enrolled. All participants performed the 6-MWT; respiratory muscle strength (RMS), including maximal inspiratory pressure and maximal expiratory pressure; and spirometry.

Clinical presentation and lung function of children hospitalized with 2009 pandemic influenza A (H1N1) pneumonia.

To determine the clinical presentation and subsequent lung function following pneumonia caused by 2009 pandemic influenza A (H1N1), pH1N1, in children aged 5-15 years hospitalized from June to September 2009, we contacted patients meeting the criterion 3-6 months post-hospitalization. Of the 88 patients contacted, 31 (35.2%) had pH1N1 and 57 (64.

Severe obesity is a risk factor for severe obstructive sleep apnea in obese children.

Objective: To determine the association between degree of obesity and severity of OSA in Thai children

Material And Method: The present retrospective study recruited obese children aged 3 to 15 years who had habitual snoring and underwent polysomnography (PSG) between January 2009 and June 2010. Obesity was defined as percentage of ideal weight for height (%W/H) > or = 120 and was classified as mild (%W/H of 120-139), moderate (140-159), severe (160-199) and morbid (> or = 200). OSA was classified as severe (AHI > or = 10) and non-severe (AHI < 10).
