The trend of the prevalence of overweight is almost stable, with a slight decrease in 2014 and 2016 with respect to the previous rounds: the prevalence of obesity shows, instead, a steadily decreasing trend. However, profound regional differences still remain, with southern regions such as Calabria, Campania and Molise showing rates of overweight and obesity above 40%, while northern regions remain below 25%. The Okkio report identifies large regional differences in the availability of gyms in schools, initiatives for the promotion of healthier eating habits, and the percentage of schools that offer lunch, which is generally thought to result in healthier meals (below 50% in the south compared to 90% in the north).
