“…18 However, this finding is contradictory to the previous findings which demonstrated that increased BMI correlates positively with a reduced PEFR rate compared to their peers during childhood, young children who are overweight or obese. 8,9 The study by Philominal SS et al 15 reported a significant difference in the PEFR rate between obese and normal. Other studies by Liyanage 12 and the study conducted in Nigerian children did not find any differences in the BMI groups among both girls and boys.…”

BACKGROUNDThe aim of this study was to examine the difference in the measure of Peak Expiratory Flow Rate (PEFR) between overweight, obese and non-obese school going children in the age group of 8-13 years. MATERIALS AND METHODSA cross-sectional study was conducted involving 643 healthy school going children aged 8-13 years. The study was conducted in one secondary school selected in the urban area of Puducherry between August and September 2017. After baseline data collection including height and weight, BMI was calculated using the Quetelet index. The PEFR was measured using a mini-Wright Peak flow meter. For the study, the highest of the three measurements were recorded. RESULTSThe study included 643 healthy students, out of which 391 and 252 were boys and girls respectively. Out of 643 children, 590 were in the ideal weight range while 28 and 25 categorized as obese and overweight respectively. The prevalence of overweight and obesity among children in the age group of 8 to 13 years was 3.9% and 4.4% respectively. The present study showed that PEFR was significantly higher in the obese group (256.07±55.47 L/min), than overweight (252.00±51.24) and non-obese group (224.15±53.74, p<0.001). CONCLUSIONThe present study showed a significant difference in the PEFR rate between obese, overweight and normal groups where higher PEFR has been reported on obese than normal. Excess weight directly and positively affects the PEFR, while further investigations on the underlying mechanism is warranted. HOW TO CITE THIS ARTICLE:Babu RV, Devaraj VS, Harish VKS.

“…Moreover, obesity can directly impair respiratory health by increasing oxygen consumption and carbon dioxide production, reducing peak expiratory flow (PEF), and augmenting the mechanical work of breathing ( 4 ). Few studies have found that PEF values are significantly lower in obese children compared to their normal-weight peers ( 5 , 6 ). Respiratory function is compromised in obese children due to decreased compliance of the chest wall and lungs and increased respiratory resistance ( 7 ).…”

Highlightsl Few studies have explored the connections between pulmonary function, physical activity, and core performance in overweight and obese children and adolescents.l To our knowledge, this is the first study to compare pulmonary function, physical activity, and core performance across normal-weight, overweight, and obese adolescents and to examine their interrelationships.l This study revealed that both pulmonary function and core performance are linked to obesity, while pulmonary function and physical activity are correlated with being overweight.

Background: The relationship between oxygen saturation (SpO2) and peak expiratory flow rate (PEFR) in patients with acute asthma is variable. Aim: This study aims to assess the predictive value and correlation of this relationship in identifying children with mild symptoms of asthma exacerbation and defining their role in guiding early intervention decision-making. Patients and Methods: This was a retrospective review of the register of children with asthma seen at the respiratory clinic of a tertiary center in Nigeria from April 2014 to February 2020. Information on their biodata, medical history, clinical status, baseline SPO2, and %predicted PEFR was retrieved and analyzed. Results: The mean values for participants with no symptoms and those with mild symptoms of asthma exacerbation were respectively: SpO2 was 97 ± 1.6% and 96 ± 2.6% (MD: 1.2; 95% CI; 0.7–1.7, P < 0.001); %predicted PEFR: 77.8 ± 17.8 and 64.1 ± 23 (MD; 13.68; 95% CI; 7.3 to 20.0, P < 0.001). Among those with uncontrolled asthma who were having mild symptom exacerbation of their asthma, the correlation between SpO2 and %predicted PEFR was significantly moderate (r = 0.44, P = 0.04). Children with SpO2 between the range of 92%–95% were significantly more likely to have mild symptoms of asthma exacerbation (OR: 2.52,95% CI: 1.22, 5.2, P = 0.01) compared to those with SpO2 >95%. Conclusion: Children with SpO2 of <95% are more likely to have an acute asthma exacerbation. While SpO2 and PEFR have more role in identifying children without acute asthma exacerbation and a limited role in identifying children with mild symptoms of asthma due to their exacerbation due to their moderate to poor correlation.
