Air pollution has been suggested to affect preeclampsia, but more data is needed to assess what components in air pollution that drives the effect.
The MAPSS (Maternal Air Pollution in Southern Sweden) cohort consists of linked registry data for around 48,000 pregnancies from a birth registry and exposure data based on residential addresses. Relevant confounders, such as parity, were available from the birth registry. Measures of air pollution exposure were obtained through dispersion modelling with input data from an emissions database with high resolution (100 m grids) for particles of different sizes and by different sources. Socio-demographic variables were added from Statistic Sweden.
Our study found consistent effects of particles on risks of preeclampsia. Smaller particles <1 μm tended to have larger effects.
To conclude our study found consistent air pollution effects for preeclampsia.
