Interventions to prevent malnutrition or overweight in children focus on the diet, and give little attention to the behaviors of their caretakers. In their first two years of life, children adopt practices that are embedded in their environment and the behaviors of their caretakers, thus turning into nutrition patterns that will persist during their lifetimes. Therefore, children and caretakers establish a relationship in which they recognize, construe and respond to verbal and non verbal communication signs. Feeding a child by adopting a "responsive" behavior in which caretakers provide guidance and structure, and respond to children's signs of hunger and satiety promotes self-regulation and children's awareness of healthy nutrition. In this article, we give recommendations to include responsive nutrition and model healthy eating behaviors in nutritional interventions. [ABSTRACT FROM AUTHOR]

Introduction and objective: Feeding with soy has been related to alteration of thyroid function. The objective of this study was to determine thyroid functionalism in babies under 6 months of age fed with infantile soy based formula. Methods: Descriptive, cross-sectional, non experimental study. Twenty eight babies who received exclusively infantile soy based formula were evaluated. Variables studied were: age, gender, socio-economical level, reason for the prescription of soy formula, dilution, daily ounces, determination of free T3, T4 and TSH. For the statistic analysis, Student's t test was applied for a statistical significance level of p< 0.05. Results: Serum free T3 and T4 were within normal ranges. 7% of the sample showed elevated levels of TSH, with no statistic significance. Conclusion: there was no statistical relationship between consumption of soy formula and thyroid function. However, two patients had increased levels of TSH and therefore, the possibility of an association cannot be ruled out given the small size of the sample. [ABSTRACT FROM AUTHOR]
