Impact assessment on health outcomes and costs of health policies on dietary risk factors (sugary drinks) in the Spanish population

Thursday 20 August 2015, 10.30AM to 11.30am

Speaker(s): Javier Mar, Alto Deba Hospital, Mondragón, Spain

Abstract: This project deals with the evaluation of the NAOS Strategy (AESAN) that includes, on one side, reducing salt intake from all sources to less than 5g/day and, on the other side, the imposition of a tax on sugary drinks that would increase their price by 20% by measuring the health impact and cost of these two health policies.

The study design is based on the mathematical representation of the natural history of diseases associated with both the level of dietary salt and sugary drinks by discrete event simulation (DES). The consumption of salt determines the risks of stroke, myocardial infarction and mortality from other causes. The level of consumption of sugary drinks is related to caloric intake and therefore obesity-related risks will be analyzed (stroke, acute myocardial infarction, diabetes mellitus, breast cancer, colon cancer and death from other causes). The model will be based on epidemiological parameters relevant for each health policy. Once the model is validated, different risks will be modified according to the effect of each specific health policy and health outcomes and cost will be measured in both scenarios.

Two approaches will be used to run the model in each scenario (with and without intervention). The multi-cohort approach will measure population outcomes (epidemiological rates) and the single-cohort model will supply individual outcomes (hazard ratios of events). Healthcare costs will be measured with both models (multi-cohort and single-cohort).
