title: Overweight and obesity in Italy, 1990-91.
abstract: Overweight and obesity are associated with several important diseases, including diabetes, cardio- and cerebrovascular diseases, digestive disorders and cancer. We decided, therefore, to present estimates of the prevalence of overweight and obesity in the general Italian population. The prevalence of overweight and obesity in Italy was evaluated using data from the 1990-91 Italian National Health Survey. 25,818 households were surveyed, representing the whole Italian population. A sample of 24,602 males and 26,090 females aged 15 or over was randomly selected, within strata of geographical area, size of municipality and size of household, in order to be fully representative. Quetelet's index was considered as a measure of body mass index, on the basis of self reported height and weight, and was a priori divided into four levels: underweight (< 20 kgm-2), normal weight (20 to 24.9 kgm-2), overweight (25 to 29.9 kgm-2), and obese (> or = 30 kgm-2). In the overall national sample, 11.0% of subjects were underweight (4.4% males, 12.2% females), 50.8% normal weight (49.4% males, 52.2% females), 31.6% overweight (39.2% males, 24.5% females), and 6.5% obese (7.0% males, 6.1% females). The prevalence of overweight and obesity was higher in middle age and in the South of the country, and was directly related to history of diabetes, hypertension, heart diseases, gallbladder disease and chronic respiratory disorders. These data quantify the importance of overweight and obesity as a public health issue in the general Italian population.
