Relationship between Parental Smoking and Children’s Pulmonary Function

Abstract

Purpose: To Study/Understand the Exposure-response Relationship between Parental Smoking and Children’s Pulmonary Function Materials and Method: Participants were selected randomly who fit into the inclusion criteria. Selected participants to be then made understood for the nature of study. Subjects were asked to seat upright on table / stool facing the Spirometer machine. Spirometer was done with the RMH Helios computerized Spirometer. Subjects were asked use nose clip and exhale complete and maximum air for long duration then immediately take deep inspiration followed by complete and maximum expiration for long time. Out of 3 or 4 manoeuvres the best manoeuvre was selected and % predicted of FEV1, FVC, FEV1/FVC, PEFR, FEF25-75 was documented. Results: Statical analysis was done by using Parametric (unpaired t test) and or nonparametric (Mann Whitney) statical test with 95 % class interval (one tailed p). Spearman’s correlation test was obtained to check the relationship between variables. Conclusion: There is a significant reduction in PEFR due to obstructive effect of parental smoking (passive smoking) on pulmonary function of the children. And with increase in number of packs per years, there is a reduction in FEV1, FVC, PEFR and FEF25 -75 of children. Keywords: Passive Smoking, Pulmonary Function, children.
