Abstract
Objective:

Overweight has been increasing in several developed countries over the last few decades. No update information on the issue is available for Italy.
Design and setting:

We conducted a computer assisted personal in-house interview survey in March?April 2004, on a sample of 2932 Italian individuals (1407 men and 1525 women) aged 18 years or over, representative of the general adult Italian population. Information on weight and height was self-reported.
Results:

Overall, 3.4% of the Italian adult population were underweight (<18.5 kg/m2, 0.9% of men and 5.8% of women), 31.3% were overweight (25.0?29.9 kg/m2, 38.4% of men, 24.7% of women), and 8.2% were obese ( 30.0 kg/m2, 7.4% of men and 8.9% of women). Overweight or obesity was reported by 14.2% of subjects aged 18?24 years (20.6% of men and 7.6% of women). The highest proportions of overweight and obese subjects were in the 45?64 year age group for men (51.4% overweight, 10.0% obese) and in the 65 year age group for women (38.8% overweight, 13.8% obese). Age- and sex-standardised prevalence of overweight or obesity was 36.0% for more educated subjects, and 54.0% for less educated ones. It was 32.3% in northern, 44.3% in central and 47.0% in southern Italy. Overweight increased from 1983 to the early 1990s, and levelled off thereafter. Prevalence of obesity remained around 8?9% across the last 20 years.
Conclusions:

Trends of overweight and obesity in Italy are more favourable than in several developed countries. Still, approximately 15 million of Italian adults are overweight and 4 million obese
