Abstract

Chewing tobacco may play a contributing role in complications during pregnancy as it contains various kinds of toxic metals such as lead (Pb), cadmium (Cd), cobalt (Co), manganese (Mn), chromium (Cr), and can cause alteration in serum metal concentration. Hence, the present study aimed to explore the effects of chewing tobacco consumption on serum metal contents in pregnant women. A total number of 200 chewing tobacco consumer pregnant women and 200 age-matched non-consumer pregnant women were selected for the study from the outpatient department of gynaecology at Rural Health Centre Tandojam, Pakistan. After obtaining the sociodemographic characteristics of all participants, 10 ml of venous blood was also drawn for serum metal analysis by atomic absorption spectroscopy. Different chewing tobacco samples consumed by consumer pregnant women were collected from local shops of Tandojam, Pakistan. Drinking water samples from the residential areas of consumer and non-consumer pregnant women were prepared and analysed for the same metal contents. In present study, serum Pb, Cd, K and Co were found significantly increased in CPW as compared to NCPW. Serum Pb was found significantly increased in gutkha consumers in comparison to mainpuri consumers. Serum Pb, Cd, and Co were present with significantly increased concentration in serum of CPW who were taking canal and well water for drinking purpose when compared with NCPW. Significant negative strong correlation of serum Pb with K and Cr of drinking water and Na of chewing tobacco samples were observed. Strong positive correlation of serum Cd and Cr with Co of drinking water had been observed. Whereas, serum maternal Co was strongly negatively correlated with Mn of chewing tobacco samples, and serum Cu of CPW had a strong positive correlation with K and Cr of drinking water and Na of chewing tobacco samples. In conclusion, consumption of chewing tobacco alters the serum metal contents in pregnant women at Tandojam and adjoining areas, Pakistan.
