Classification of original deprivation indices used in public health

Abstract

Abstract Background Many studies around the world have been carried out to establish the association between deprivation and health outcomes. Both separate deprivation indicators (income, education) and indices that include several ones are used. Deprivation indices have been actively used in public health since the mid-80s of the last century. Nowadays, there is no clear classification of deprivation indices. Methods In order to create a taxonomy of deprivation indices, scientific publications related to the development and application of indices have been combined, analyzed, and systematized. The search was carried out in two bibliographic databases (PubMed and Google Sholar). After conducting a full-text review and searching and adding relevant papers from the bibliography, and adding papers that were already known to the authors, 61 documents were included in the study. These documents referred to 61 original deprivation indices. Original index is defined as “an index that includes a combination of deprivation indicators that is unique and not repeated in other indices”. Results Four key characteristics of the indices included in the classification were determined: type of deprivation, spatial scale, data source and weighting method. To create the taxonomy, an integrative approach was used that allows you to add new classes and subclasses when new information appears. In accordance with the type of deprivation 72% (44 \ 61) socio-economic, 7% (4 \ 61) material deprivation, 5% (3 \ 61) environmental deprivation and 16% (10 \ 61) multidimensional indices were identified. Conclusions The terms and definitions introduced during the review are aimed at ensuring uniformity in the taxonomy and finding a common language among researchers and specialists who develop and use indices. We also hope that the data from the study will stimulate the use of a competent approach and will help in resolving conflicts or inconsistencies that arise during the construction and use of indices. Key messages Development of the first classification of deprivation indices. Stimulation of the use of competent approach and thus help researchers and public health professionals resolve conflicts or inconsistencies in the construction and use of indices.
