The growth of primary school-children was investigated in three different age-groups. On October 2007, weights and standing heights of 261 (116 girls; 145 boys), 277 (142; 135), and 289 (139; 150) respectively 6, 7, and 8yr-old primary school-children were measured in Voghera (Pavia, Italy). Body Mass Indices (BMI) were calculated. The measurements were repeated 1 and 2 years later. Within group of age, descriptive statistics of each parameter were computed within age, sex and session of measurements. Comparisons were performed by ANOVA (F1, factor 1, sex; F2, factor 2, age; F1×F2 interaction). Statistical significance was set at 5% for all comparisons. Frequencies and percentages of school-children relatively under- (97th percentile) were computed, while comparing BMI to reference data for Italian children (1, 2). On average, weight, height, and BMI were larger in boys than in girls. Differences between sexes were significant (F1, p
