Does the effect of gender modify the relationship between deprivation and mortality?
In this study we propose improvements to the method of elaborating deprivation indexes. First, in the selection of the variables, we incorporated a wider range of both objective and subjective measures. Second, in the statistical methodology, we used a distance indicator instead of the standard aggr...

Does the effect of gender modify the relationship between deprivation and mortality?Salcedo, NataliaSáez Zafra, MarcBragulat, BasiliSaurina, CarmeMortalitatMortalityEstadística bayesianaBayesian statistical decision theoryIn this study we propose improvements to the method of elaborating deprivation indexes. First, in the selection of the variables, we incorporated a wider range of both objective and subjective measures.

Methods We conducted an ecological small-area analysis based on the residents of the Metropolitan region of Barcelona in the period 1994–2007.

Socioeconomic conditions were summarized using a deprivation index. Sixteen socio-demographic variables available in the Spanish Census of Population and Housing were included. The deprivation index was constructed by aggregating the above-mentioned variables using the distance indicator, DP2.
