“…, 18 To date, no study was found carried out in the Brazilian pediatric population that aimed to evaluate the influence of obesity on lung volume and capacity. Perhaps this lack of information at the national level is because there are few body plethysmographs in the country, as well as the high cost of the equipment and also the fact that it is harder to obtain a satisfactory test in a pediatric sample 26. Most studies used SensorMedics equipment17 , 19 , 20 and all of them normalized of lung volume results through the percentage of predicted,17 - 20 although a study did not report the equation used 18…”

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.

“…These findings are similar to those found in various studies that evaluated the lung function success rates in the pediatric population, showing that as the children grow older, the success rate also rises. 21 , 23 , 24 Previous studies that aimed at generating normality values for the respiratory muscle strength test ascribe the failure of the technique to the difficulty in understanding, low reproducibility and lack of cooperation by the children in this age group. 13 , 14 However, these studies have not demonstrated success rates separately by age groups, hindering a better knowledge and understanding of the age as an influencing factor on this outcome.…”

Objective:To determine the success rate of the manovacuometry test in children between 4 and 12 years of age.Methods:Cross-sectional study involving children and adolescents from 4 to 12 years of age, enrolled in three basic education schools. All subjects had the anthropometric and respiratory muscle strength (maximum inspiratory pressure and maximum expiratory pressure) data measured. Students whose parents did not authorize participation or who did not want to undergo the test were excluded. The test was considered successful when the subject reached acceptability (no air leaks) and reproducibility (variation <10% between the two major maneuvers) criteria established by guidelines. Failure was defined when subjects did not meet the above criteria. Data were expressed as mean and standard deviation and the categorical variables in absolute and relative frequency. The comparison between proportions was performed using the chi-square test.Results:We included 196 children and adolescents, mean age of 8.4±2.5 years, 53.1% female. The success rate of the manovacuometry test in children and adolescents evaluated was 92.3%. When comparing the differences between the success rates of preschool children with those children and adolescents of school age, there was a significantly lower success rate in the pre-school (85.1%) group compared to the school group (94.6%) (p=0.032). However, no significant differences (p=0.575) were found when gender comparisons were performed.Conclusions:The manovacuometry test showed a high success rate in both preschool and school population assessed. Furthermore, the rate of success appears to be related to aging.

“…It was reported that the use of trained evaluators and a laboratory adapted to children increases the success of spirometry in this age group 23 . The use of incentives of animation and the previous training of the spirometry maneuver by employing a plastic bottle filled with water and a straw with the same diameter of the mouthpiece for simulation of expiration before the test may have contributed to explain our high success rate in the two groups evaluated [27][28][29] .…”

“…Recently, a literature review 2 showed that the success rate in the preschool age group varied between 71-92% in various regions of the world, corroborating our results in this age group evaluated, 76%. Similarly, other studies that evaluated the applicability of spirometry test in the school age group showed a success rate of approximately 90% 4,29,31 , with spirometry measurements performed by a team previously trained and experienced with children. It was reported that the use of trained evaluators and a laboratory adapted to children increases the success of spirometry in this age group 23 .…”

“…This is the first study aimed at assessing success rate according to age group in manovacuometry test in preschool and school children, which complicates the comparison of our results with other studies. However, it is believed that our success rate is considered too high, taking into account the success rate observed in other pulmonary function tests, such as spirometry tests, plethysmography, which showed values between 75-92% [27][28][29][30] . Our results can be attributed to a few factors, such as prior experience of evaluators, detailed explanation of the technique, previous training, long time of measurement, and the patience of the evaluator responsible for measurements.…”

| The aim of this study was to evaluate the success rate of preschool and school children with/without respiratory symptoms in pulmonary function tests. Children and adolescents, aged 4 to 12 years, with/without respiratory symptoms based on the questionnaire of respiratory diseases were included. Participants were recruited from two schools and classified according to their age group in preschool children (4-6 years) and school children (7-12 years). We collected demographic and anthropometric data, and the variables of the manovacuometry test (MIP and MEP) and spirometry test (FEV1, FVC, FEV1/FVC, and FEF25-75%).Pulmonary function tests were considered successful when the participants reached acceptability and reproducibility criteria established by national and international guidelines.In the statistical analysis, we used the chi-square test and Pearson correlation test. We included 148 participants, mean age of 8.1±1.7 years, being 51.4% female and 85.1% healthy. The success rate for the manovacuometry test and spirometry was 91.9% and 91.2%, respectively. There was a significantly lower success rate in the preschool group, compared to school children for both manovacuometry (p=0.044) and spirometry (p=0.015) tests. We found positive correlations between the MIP and FEV1 and MEP and FEF25-75%. The findings demonstrated a significantly lower success rate in 1 93 preschool age group, compared to pre-school subjects in both pulmonary function tests evaluated..
