Socioeconomic IneQuality in Exposure to environmental Risk factors in Sweden (SIQER) - air pollution, traffic noise and access to green space in low- and high income areas

Socioeconomic factors are associated with lifestyle factors and health risks.

Cardiovascular and metabolic diseases are related to both lifestyle and environmental exposure such as air pollution, traffic noise and greenness.

The association between exposure and socioeconomic status is complex, though.-How are socioeconomic factors (on individual level and area-level) associated with exposure to air pollution, traffic noise and access to green areas?-When moving to another area, does the change in exposure differ between socioeconomic groups?   -How does socioeconomic status modify the associations between environmental exposures and health?We use the population based SCAPIS cohort (30,000 persons, 6 cities), with socioeconomic, sociodemographic and health data.

Address history (2000-2018) enables assessment of air pollution, traffic noise, greenness, and area-level socioeconomic markers.The health impact is evaluated through diagnoses and biomarkers.

Also, health effects are illustrated by combining our results (exposure-socioeconomic status) with risk functions for exposure and important health outcomes.Multilevel analysis is used, with individuals nested within areas.

Differences in response rates, related to e.g. age, education, are adjusted using weighting.Physical environment inequality affects health.

The project investigates associations between environmental exposure and socioeconomic status, and the relative impact on health in Sweden.
