We apply panel data econometrics and use a two-part model with a longitudinal dataset of medical and administrative records of patients in primary and secondary healthcare centres in Spain followed up over seven consecutive years (2004- 2010). Our findings show a positive and statistically significant impact of BMI, obesity and overweight on annual medical costs after accounting for data restrictions, diferent subsamples of individuals and various econometric approaches.40 p.application/pdfengcc-by-nc-nd, (c) Mora Corral et al., 2012http://creativecommons.org/licenses/by-nc-nd/3.0/es/Pes corporalObesitatAnàlisi de dades de panelEconometriaBody weightObesityPanel analysisEconometricsinfo:eu-repo/semantics/workingPaperinfo:eu-repo/semantics/openAccess
