Race differences in the relationships between dietary nutrients and overweight in women.

Increasingly overweight is a health problem in the United States, especially for African American (AA) women. Height, weight, and 24-hour dietary recall measurements from 46 European American (EA) and 44 AA women were used to assess the relationships between nutrients and overweight and the possible modifying effects of race. Significant race interactions were found when assessing the relationships between overweight and fats and mineral supplements. More EA women were overweight who had excessive fat intake, whereas more AA women were overweight who had appropriate fat intake. This reversed pattern for AA women was unexpected. Another unexpected finding was that overweight EA women used mineral supplements more frequently than nonoverweight EA women. These results were discussed in terms of energy imbalances, metabolic differences, and cultural differences. Additional studies of overweight assessing race and other biological factors that also include measures of energy expenditure and more precise measures of dietary energy intake are recommended.
