Portuguese measure of multiple environmental deprivation (PT-MEDIx)

PT-MEDIx was built at municipality level in four stages: (i) identify health-relevant environmental factors; (ii) acquire datasets about selected environmental factors and calculate municipality-level measures using Geographical Information Systems; (iii) test associations between selected environmental factors and mortality using negative binomial models, adjusting for age, sex, socioeconomic deprivation and interactions and (iv) construct a summary measure and assess its association with mortality.We included five dimensions of the physical environment: air pollution, climate, drinking water quality, green space availability and industry proximity. PT-MEDIx score ranged from -1 (least environmental deprivation) to +4 (most) and depicted a clear spatial pattern: least deprived municipalities in the depopulated rural areas and most deprived in urban and industrial settings. Comparing with those in the intermediate category of environment deprivation, less deprived municipalities showed lower mortality rate ratios (MRRs) and vice versa: MRRs for all-cause mortality were 0.962 (95% confidence interval: 0.934-0.991) and 1.209 (1.086-1.344), in the least and most deprived municipalities, respectively, and for cancer, 0.957 (0.911-1.006) and 1.345 (1.123-1.598).<br>More details here:Ribeiro, A.
