The following diseases have been analyzed: ischemic heart disease, type 2 diabetes, colon cancer, breast cancer, overall mortality. Methods. The indicators used are: number of cases and PAF (Population Attributable Fraction). Surveillance System Steps using the conversion factors used by the reference I-Min Lee’s study. Results. Analysis of the results showed that the prevalence of inactive in the Italian national territory is higher in the south than in the north. Therefore, the fraction of disease attributable to physical inactivity considered varies from region to region presenting around twice in the most virtuous regions, compared to the most needed. Conclusions. The data obtained through the heads of the "inactive" in the individual regions makes it possible to detail the percentage of diseases due to physical inactivity and consequently estimate the terms of health gain that would be obtained if we eliminated / we reduced the prevalence of physical inactivity at the local level.
