Influence of Domestic Exposure to Polycyclic Aromatic Hydrocarbons on Women's Periconceptional Stage and Associated Risk of Oral Cleft in Offspring

BACKGROUND: Polycyclic aromatic hydrocarbons (PAHs) constitute a group of chemicals with an omnipresence in the environment and our surroundings. With their genotoxicity and carcinogenic nature, it has been proven to be monstrous in our daily life and, especially for pregnant women and their newborn. AIM: This questionnaire study was done to verify the influence of domestic exposure to polyaromatic hydrocarbons on women's periconceptional stage and risk of oral cleft in offspring in the suburban and the rural population of Mysore. METHODOLOGY: Two hundred pregnant women as patients from four different hospitals in Mysore were given a questionnaire to be filled with 24 parameters ranging from the knowledge to various means of exposure to the pregnant women with the PAH and the severity and the extent of the orofacial defect in the newborn. RESULTS: It was determined that exposure of pregnant women to the smoke emanating from the method of cooking or heating to smoking (first or passive) and the direct inhalation of gas had the maximum effects on the association of cleft palate (60.7%) in unilateral followed by 90.9% in bilateral, 65.0% in soft tissue, and 76.2% in hard tissue cleft palate. CONCLUSION: The deleterious effects of the cooking and water heating measures practiced in the suburban and the rural population predisposed the pregnant women to significantly higher chances of offspring with the varied extent of the orofacial defect. There is an influence of domestic exposure to polycyclic aromatic hydrocarbons on women's periconceptional stage and risk of oral cleft in offspring.
