Association of raised blood lead levels in pregnant women with preeclampsia: A study at tertiary centre.

Objective: This study aims to find the blood lead levels in pregnant women and its association with pre-eclampsia.

Material And Methods: The study included 44 healthy pregnant females and 23 pre-eclamptic women. Demographic data and common risk factors for lead toxicity were recorded including age, residence, occupation, husband occupation, passive smoking, use of cosmetics, kajal, surma, receiving supplements/vitamins, history of house remodelling, plumbing, source of potable water, paint in house, use of lead-glazed ceramic and pica. Venous blood was collected and lead level was determined by atomic absorption spectrometry.

Results: The mean blood lead level was 2.38 ± 2.43 ug/dL in controls and 3.42 ± 2.18 ug/dL in preeclamptic women which was significantly higher (p = 0.0132). Strong correlation of BLL was observed with blood pressure in pre-eclamptic women. Pre-eclamptic patients were observed to be at increased risk of being lead exposed in terms of occupation and living conditions.

Conclusion: Higher blood lead level is associated with increased risk of preeclampsia. Patients should be counselled for lifestyle modification to prevent complications.
