Dunkel Schetter said the study did not support a few of the researchers' original assumptions, including their hypotheses that African-American and Hispanic parents would have higher levels of most kinds of stress, and that stress would be a major reason for the racial and ethnic disparities in health.
"It wasn't that clear cut," she said. "There were forms of stress that were higher in whites than in African-Americans and Hispanics, there were forms of stress that were quite low in the African-Americans even when they were poor, and there were forms of stress that varied in Latinos, depending on whether they were U.S.- or foreign-born."
The study did find that:
A mother who wasn't living with the father of her baby was likely to have higher stress levels than one who lived with the baby's father.
