PULMONARY FUNCTIONS AND ITS CORRELATION WITH SERUM IRON LEVELS IN WOMEN AT THE THIRD TRIMESTER OF PREGNANCY
Background and Objectives: There is a series of physiological alterations that taken place during pregnancy as a result of gradual growth of the fetus. Among alterations that occur during pregnancy are changes in the lung volumes. In this study we aim to evaluate the pulmonary functions in pregnant women at the third trimester of pregnancy and to determine the correlation between pulmonary functions and serum iron levels.
Methods: Physical examination as well as case history and all requested information were taken by a questionnaire. Measurement of serum iron was done manually using commercial kit (Biolab, France). Pulmonary functions test was carried out using a computerized Spirometer device (ROME-Italy).
Results: FEV1, FVC and O2 saturation % showed a decrease in study group (untreated) but were not statistically significant (p = 0.31, 0.98 and 0.14) respectively. However, only FEV1/FVC displayed a statistically significant decline in study group compared to controls. Although there was an obvious positive correlation between serum iron and FEV1, FVC and FEV1/FVC, none of them showed a statistically significant correlation (r = 0.238, 0.493 and 0.969) respectively.
Conclusion: Decline in lung volumes is correlated (although not significant) with low serum iron in pregnant women at the third trimester.
