Teenagers whose dietary behavior was eating at home between five to seven times on a weekly basis, their consumption of kilocalories, proteins, iron and calcium is either adequate or very close to be, and the same for A serum vitamin. The lowest nutritional condition was registered in Navojoa which is placed in the south region of the Sonora state.
