Trends and differentials in dietary patterns and nutrient intake among migrant Puerto Rican families.

Preoccupation to define the nutritional status of Puerto Rican families migrating to the United States, motivated the present research. A total of 526 families residing in the South Bronx, New York, and four communities in Puerto Rico, were therefore studied. Results in regard to nutrient intake suggest that the mothers' diets appear to be adequate in the South Bronx as well as in Puerto Rico, except in iron consumption, in the latter. Furthermore, the data show an apparent tendency to overconsumption of certain foods in both the South Bronx and Puerto Rico, particularly of the protein group, as well as a high consumption of sugar and carbonated beverages in Puerto Rico. Dietary data were corroborated through nutritional anthropometry, conforming a tendency for overweight and obesity among the women studied. Detailed information on the dietary changes occurred during the last five years, is provided. Educational programs such as EFNEP, availability of new foods, and the food preferences of children in their homes, seem to be influencing factors in the dynamics of food modifications within societal groups in transition.
