Abstract

in women. Mean level of self-reported BMI was 26.7kg/m2 (26.3-27.2kg/m2) in men and 25.3 kg/m2 (24.8-25.9kg/m2) in women. Conclusions: In 2023-2024, obesity prevalence resulted similar to HES data of 15 and 5 years ago, both in men and women, going in the direction of WHO target. However, 70% of men and 55% of women are in the overweight/obesity condition. Preventive actions at national and community level should be still massively implemented. Significant differences were found between measured and self-reported obesity supporting the WHO recommendation to monitor targets by periodic HESs. Key messages: • A quite stable obesity prevalence trend was observed in comparison to 15 and 5 years ago, but obesity and overweight resulted still prevalent in the Italian adult general population. • Significant differences resulted between measured and self-reported obesity prevalence supporting the WHO recommendation to monitor targets by periodic health examination surveys.
