We studied 78 teenagers from Iaşi Pedagogic High School. Body mass index values are mainly (83.3%) normal. 60.3% of the teenagers are coming from rural areas, but there are no significant differences between children coming from urban and rural areas. The frequency of families with more than 5 children in the urban areas is very small (1.3%), but in the rural areas this frequency is more than 10 times higher (15.4%). Due to this factor, the per capita income is reduced in the rural areas. Nutrition is a major problem in both urban and rural areas, due to unbalances food intake.
