“…Dynamic lung functions, such as FVC, FEV 1 , peak expiratory flow rate (PEFR), and forced expiratory flow (FEF), and static lung functions, such as tidal volume (TV), inspiratory reserve volume (IRV), inspiratory capacity (IC), and maximum voluntary ventilation (MVV), were measured. 13,14 Under the supervision of observer from pulmonary medicine, a trial run was carried out to familiarize and accommodate participants to the procedure. Subjects were instructed to perform deep and rapid expiration through the mouthpiece of the spirometer followed by deep inspiration.…”

Aim and objective: Pregnancy is often accompanied by physiological variations, especially variations in the respiratory function. However, there is insufficient information regarding the association of hormonal changes and pulmonary function tests in different trimesters of pregnancy. Hence This was aimed to assess the effects of progesterone levels on the lung function of pregnant women. Materials and methods: A total of 150 pregnant women comprising 50 women in each of the 3 trimesters of pregnancy were recruited for this study to compare the lung function variations across the trimesters. Both dynamic and static pulmonary function tests were measured. Serum progesterone and blood hemoglobin levels were also estimated. Data was analyzed using ANOVA and Kruskal-Wallis test. Tukey's HSD and Dunn's test were used as post hoc tests. p < 0.05 was considered as statistically significant. Results: Variations in the lung functions were observed across all the trimesters of pregnancy. Among the dynamic lung function tests, peak expiratory flow rate (PEFR, p = 0.0043) and forced expiratory flow (FEF, p = 0.0151) were significant in the first trimester. PEFR (p = 0.0047) and FEF (p = 0.016) were significant in the second trimester. Among the static lung function tests, maximum voluntary ventilation (p = 0.0003) was a significant variable in the second trimester. Progesterone levels were significant in all the 3 trimesters of pregnancy (p < 0.0001) and were associated with increased gestational age. In contrast, hemoglobin levels were insignificant throughout pregnancy (p = 0.8548). Conclusion: The progesterone levels did not have any significant association with the pulmonary function test during gestation. Clinical significance: The chronic respiratory diseases ranked third most cause and in order to evaluate any respiratory ailment during pregnancy, an accurate knowledge of the physiological changes in pulmonary functions during normal pregnancy is necessary.

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.
