ISGlobal: Environmental exposures during pregnancy and childhood could affect blood pressure in children

News from ISGlobal

A new study led by the Barcelona Institute for Global Health (ISGlobal), used an holistic approach to analyse more than 200 environmental exposures during pregnancy and childhood. The study, published in the Journal of the American College of Cardiology, concludes that some of the exposures analysed could have an impact on blood pressure in children.

The study was carried out as part of the HELIX project, which compiles data from cohorts in six European countries (Spain, France, Greece, Lithuania, Norway and the United Kingdom), and included a total of1,277 children and their mothers. Exposures were assessedduring pregnancy and when the children were between 6 and 11 years of age. The children underwent a clinical examination that included blood and urine sample collection and blood pressure measurements.

The researchers assessed a total of 89 prenatal and 128 postnatal exposures grouped in three categories: outdoor exposures (air pollution, meteorological conditions, green spaces, etc.), chemicals (pesticides, metals, plasticisers, etc.) and lifestyle factors (diet, physical activity, sleep patterns, etc.).

“Our results show that, starting in the foetal stage, where we live, the food we eat, the air we breathe and the chemical compounds that reach our bodies can affect blood pressure before adolescence. This is important because evidence shows that children with high blood pressure are more likely to be hypertensive as adults,” commented ISGlobal researcher Charline Warembourg, the lead author of the study.
