Polish Mother and Child Cohort Study

Polish Mother and Child Cohort Study

Initiatives -
The aim of the study is to evaluate the impact of exposure to different environmental factors during pregnancy and after birth on pregnancy outcome and children's health. Specific research hypotheses refer to the role of heavy metals, exposure to polycyclic aromatic hydrocar-bons (PAHs) and environmental tobacco smoke (ETS) in the aetiology of intrauterine growth retardation (IUGR), preterm delivery (PD) and the risk of respiratory diseases, allergy and poor mental and physical development. It is also intended to explain the role of oxidative stress and nutritional status of the pregnant women. The impact of occupational exposures and stressful situations on pregnancy outcome will be evaluated from question-naire data.

Population cohort
Follow Up
The follow-up of the women at 8-12, 20-24 and 30-34 weeks of pregnancy consists of the collection of biological samples and a questionnaire. Biological samples are collected during delivery and 2 more visits after delivery are conducted: within 1 and 6 weeks after delivery. The children are followed-up to the age of 2 years to determine long term effects of pre- and postnatal environmental exposures.
