Application of generalized propensity score for addressing continuous exposure in environmental health
Objective To introduce the method of generalized propensity score(GPS)with continuous exposures,explore its ap-plication in the field of environmental health,and provide an effective tool for measuring environmental health risks.Methods The baseline investigation data from Beijing Air Pollution and Population Health Cohort Study(2017-2018)were performed to evaluate the application effect of GPS with continuous exposures in estimating the health effect of air pollution.Results After the application of GPS with continuous exposures,there was a significant improvement in balancing of confounding factors in populations with different exposure levels.For every 10 μg/m3 increase of PM2.5 exposure,the risk of hypertension increased from 10.3%to 11.9%.Conclu-sion To a certain extent,GPS method with continuous exposures provides more accurate epidemiological evidence for studies on the association between air pollution and health.
