AMBIENT AIR POLLUTION, FETAL GROWTH AND PREMATURE BIRTHS IN POLISH URBAN POPULATION

This study investigates the association between exposure to outdoor air pollution during pregnancy and the risk of adverse birth outcomes in the urban population of Poland, focusing on low birth weight, prematurity, and intrauterine growth retardation. The study examines the effects of air pollutants such as black smoke (BS), sulphur dioxide (SO2), and nitrogen dioxide (NO2) on birth outcomes. The findings suggest that while ambient air pollution does not significantly impact fetal growth, air pollution with black smoke is a significant risk factor for premature birth.

  1. AMBIENT AIR POLLUTION, FETAL GROWTH AND PREMATURE BIRTHS IN POLISH URBAN POPULATION Bogdan Wojtyniak Jakub Stokwiszewski Daniel Rabczenko National Institute of Hygiene, Warsaw

  2. Air pollutants Black smoke (BS) Sulphur dioxide (SO2) Nitrogen dioxide (NO2) Birth outcomes Low birth weight (<2500g) Prematurity (<37 weeks) Intrauterine growth retardation Birth weight The purpose of the study was to examine if exposure to outdoor air pollution during pregnancy is associated with increased risk of adverse birth outcomes in Polish urban population

  3. Birth outcomes by the variables included in the models

  4. Birth outcomes by the variables included in the models

  5. Dose response curves for association between mean birth weight and BS during 1st trimester of pregnancy

  6. Dose response curves for association between risk of low birth weight and SO2 and BS during 1st and 3rd trimester of pregnancy in Lodz

  7. Dose response curves for association between risk of IUGR and SO2 and BS during 1st and 3rd trimester of pregnancy in Lodz

  8. Dose response curves for association between mean birth weight and SO2 and BS during 1st and 3rd trimester of pregnancy in Lodz

  9. Dose response curves for association between risk of premature birth and SO2 during 1st trimester of pregnancy

  10. Dose response curves for association between risk of premature birth and SO2 during 3rd trimester of pregnancy

  11. Risk of premature birth associated with 10mg/m3 increase in ambient SO2 concentration during 3rd trimester of pregnancy * Random effect model

  12. Dose response curves for association between risk of premature birth and BS during 1st trimester of pregnancy

  13. Dose response curves for association between risk of premature birth and BS during 3rd trimester of pregnancy

  14. Risk of premature birth associated with 10mg/m3 increase in ambient BS concentration during 3rd trimester of pregnancy

  15. CONCLUSIONS • In Polish urban population: • Ambient air pollution was not found a significant risk factor of fetal growth • Air pollution with black smoke was found a significant risk factor of premature birth
