Introduction: Adverse effects of exposure to second hand smoke during pregnancy are associated with decrease in pulmonary functions, small for gestational age babies & preterm delivery. Aim of our study was to observe the pregnancy outcome & pulmonary function tests in pregnant women exposed to second hand smoke (SHS) & in women not exposed to SHS.
Objectives: (1). To observe pulmonary function tests (PFT) in pregnant women exposed to second hand smoke & not exposed to SHS. (2) To observe the pregnancy outcome in both pregnant women exposed & not exposed to second hand smoke (SHS) like preterm delivery, caesarean section and small for gestational age (SGA) neonates.
Materials and Methods: It is a hospital-based prospective case control observational study done at department of obstetrics & gynecology, UCMS & GTB hospital, Delhi from October 2015 to March 2017. Total 204 antenatal women between 6 to 28 weeks of pregnancy were recruited. Out of these, 82 women had exposure to SHS (second hand smoke) & 122 women had no exposure to SHS. Spirometry of these women were done & FEV1, FEV6 & FEV1/FEV6 ratios were obtained. These patients were followed up till delivery for pregnancy outcome & small for gestational age babies.
Results: PFT parameters, FEV1 & FEV6 were reduced in women exposed to SHS as compared to non- exposed women (84.1% vs 64.8% & 73.2 vs 62.3% respectively). Ratio of FEV1/FEV6 (<0>
Conclusion: The study concluded that pregnant women exposed to second hand smoke have many negative effects on their lung functions and pregnancy outcome.
