Dietary differences among women of Polish descent by country of birth and duration of residency in the United States.

We examined relationships of dietary factors associated with these diseases with stage of migration among Polish women in Chicago.

Design: Women of Polish descent (N = 396) were selected from Polish women's social organizations.
