Obesity is one the main causes of morbidity and mortality in Chile, and the growing prevalence is creating a major threat to the health of the country. Chile has put in place a comprehensive portfolio of interventions, from population-level fiscal policies, to school- and workplace-focused programmes, to individual interventions in primary care. There are a number of ways in which Chile could further strengthen its portfolio of interventions, including through expanding some polices so that they cover a greater share of the population, and a greater number of food products. In addition Chile’s private health insurers – the ISAPRES – have a bigger role to play, and could do more to positively influence the health of their insurees.
