Prevalence of obesity, overweight and hypertension in children and adolescents from Abruzzo, Italy

The present survey was aimed at determining the prevalence of overweight, obesity, hypertension, their correlation and the association with gender, age and provenience, in the pediatric population of Pescara province, Italy. During the academic year 2001-2002, the body mass index (BMI) and blood pressure of 15.612 scholars aged 6-14 years (mean age 9.9), coming from all province schools, have been measured. Two scales have been used to define obesity and overweight status (one developed by the National Center for Health Statistics--NCHS--the other by Cacciari et al.); while hypertension has been attributed using National Institute of Health curves. Several multiple logistic regression models have been fitted to analyze data. According to NCHS standards, the prevalence of childhood and adolescence overweight and obesity was, respectively, 40.6% and 19.5%. Using curves by Cacciari, the prevalence were 33.3% and 7.7%. Hypertensive subjects were 11.1%. With both scales, the prevalence of weight problems widely decreased after 12 years of age, and either obesity or overweight were significantly related with male sex, hypertension and rural area residence. A strong independent association was found between living inside the city and hypertension. Although the differences in the dimension of the problem "overweight" according to the used scale, and a potential overestimation of hypertension must be taken into account, the overall data suggest an urgent need, especially for primary school children, of preventive interventions aimed at reducing both overweight and blood pressure
