OR odds ratios, CI confidence intervals
a
Each acculturation variable was included in independent multivariable logistic regression models adjusted for age, education and living with a partner
b
Increasing score indicates increasing acculturation to the Anglo/American culture
c
1st generation—participant born in PR/DR; 2nd generation—participant born on mainland and at least one parent born in PR/DR; 3rd generation—participant and at least one parent born on the mainland, but at least two grandparents born in PR/DR (PR Puerto Rico, DR Dominican Republic)
