Insights
This prospective cohort study investigates prenatal environmental exposures, including heavy metals and tobacco smoke, and their impact on pregnancy outcomes and child health in Poland. Future results will reveal exposure levels and their effects on pregnancy and child development.
Area of Science:
- Environmental Health
- Reproductive Epidemiology
- Pediatric Health
Background:
- Prenatal exposures significantly impact pregnancy outcomes and child health.
- Prospective cohort studies are crucial for identifying and verifying exposure-related effects on maternal and child well-being.
- Understanding these impacts is vital for public health initiatives and preventative strategies.
Purpose of the Study:
- To identify and evaluate the effects of prenatal environmental exposures on pregnancy outcomes and child health.
- To investigate the role of specific exposures like heavy metals, polycyclic aromatic hydrocarbons (PAHs), and environmental tobacco smoke (ETS) in small-for-gestational-age (SGA) and preterm delivery (PD).
- To explore the influence of oxidative stress and maternal nutritional status on pregnancy and child development.
Main Methods:
- The Polish Mother and Child Cohort Study (REPRO_PL) is a multicenter prospective cohort study involving 1300 mother-child pairs.
- Data collection includes questionnaires, and biological samples (saliva, urine, hair, blood, breast milk) during pregnancy and postpartum.
- Follow-up occurs three times during pregnancy and after delivery to assess pregnancy outcomes and child health.
Main Results:
- Study results are forthcoming and will quantify prenatal exposure levels in various Polish regions.
- The findings will elucidate the impact of these exposures on pregnancy course and outcomes.
- Analysis will also cover occupational exposures and stressful situations through questionnaire data.
Conclusions:
- The REPRO_PL study will provide critical data on prenatal environmental exposures in Poland.
- Findings will inform our understanding of the etiology of adverse pregnancy outcomes like SGA and PD.
- The study aims to enhance knowledge regarding environmental influences on child health from the prenatal period onwards.
Objectives:
Exposures during prenatal period have implications for pregnancy outcome as well as for children's health, morbidity and mortality. Prospective cohort study design allows for the identification of exposures that may influence pregnancy outcome and children's health, verification of such exposures by biomarker measurements and notification of any changes in exposure level.
Materials And Methods:
Polish Mother and Child Cohort Study (REPRO_PL) is multicenter prospective cohort study conducted in 8 different regions of Poland. The final cohort is intended to comprise 1300 mother-child pairs to be recruited within 4-year period (2007-2011). The recruitment and all scheduled visits are conducted in maternity units or clinics in the districts included in the study. The women are followed-up 3 times in pregnancy (once in each trimester) and after delivery for the notification of pregnancy outcome. During each visit, detailed questionnaire and biological samples are collected including saliva, urine, hair, maternal blood and cord blood. About 6 weeks postpartum, breast milk from part of the women is collected. The study concentrates on the identification and evaluation of the effects of prenatal environmental exposure on pregnancy outcome and children's health. Specific research hypotheses refer to the role of heavy metals, exposure to polycyclic aromatic hydrocarbons (PAHs) and environmental tobacco smoke (ETS) in the aetiology of small-for-gestational-age (SGA) and preterm delivery (PD). The role of oxidative stress putative mechanism and pregnant women nutritional status will be investigated. Based on questionnaire data, the impact of occupational exposures and stressful situations will be evaluated.
Results:
The results of the study will become available within the next few years and will help to determine levels of child prenatal exposure in several areas of Poland and its impact on course and outcome of pregnancy.
