title: [Calcium content in the whole-day food rations of primary school children in Bialystok and vicinity].
abstract: Randomly selected 354 primary school pupils aged 9 and 14 from Białystok and its vicinity gave a 24-hour feeding history. Calcium diet content was evaluated in the children. The values obtained were referred to the recommended standard of Ca intake according to age and sex. It was found that Ca supply in daily food rations of children in Białystok and suburbs is most insufficient, and the 9-year-old children's place of living had a significant effect on the calcium content in diets.
