Title: | Spatial smoothing models to deal with the complex sampling design and nonresponse in the Florida BRFSS survey | Authors: | WATJOU, Kevin FAES, Christel Kirby, R AREGAY, Mehreteab Carroll, R VANDENDIJCK, Yannick |
Issue Date: | 2019 | Publisher: | Spatial & Spatio-Temporal Epidemiology | Source: | Spatial and spatio-temporal epidemiology (Print), 29 , p. 59 -70 | Abstract: | Public health and governmental organizations have acknowledged the importance of obtaining information of various characteristics for small areas, such as counties. Spatial smoothing models have been developed to gain reliable information on the geographical distribution of the outcome of interest. When the geographical analysis is based on survey data, two issues pose challenges: (1) the complex design of the survey and (2) the presence of missing data due to non-response. We investigate the influence of missing data and the adjustment thereof in the context of the 2013 Florida Behavioral Risk Factor Surveillance System (BRFSS) health survey. We focus on the application and comparison of the Hajek ratio estimator and two model-based approaches for estimation of the spatial trend of the prevalence of having no health insurance coverage. The model-based methods are compared using the Deviance Information Criterion which show the benefits of modeling the weights as flexibly as possible. Methods are extended towards subgroup analyses and the estimation of area-specific standardized rates, where household incomes was identified as an important factor to include in the analysis. 1 | Keywords: | BRFSS;Complex Survey Design;Hierarchical Bayesian Modeling;Imputation Model;Missing Data;Subgroup Analysis;Standardized Rate | Document URI: | http://hdl.handle.net/1942/30594 | ISSN: | 1877-5845 | e-ISSN: | 1877-5853 | DOI: | https://doi.org/10.1016/j.sste.2019.03.001 | ISI #: | WOS:000468628600006 | Rights: | 2019 Elsevier Ltd.
