^aLevel of acculturation quantified based on six questions assessing adult English proficiency and level of interaction with members of mainstream society, with possible range from 6–24 (22).

^bP-values comparing women with acculturation scores ≤9 vs. >9, determined using Cochran-Mantel-Haenszel test statistic for categorical variables and t-test for continuous variables.

^cDue to missing values, n=239 for length of United States residence, age at migration, and body mass index.

^dDiet Quality Index (DQI) - International used to quantify overall and four specific components of diet quality – variety, adequacy, moderation, and balance (29). See Appendix for detailed description of scoring criteria.
