Weighted ORs with 95% CIs of the joint effect of Race and BMI Change on Breast Cancer Risk

	non-Hispanic white	non-Hispanic blacks	Hispanic
BMI Change
Normal throughout	Reference	Reference	Reference
Normal to Overweight	1.5 (0.86-2.65)	4.2 (1.02-17.75)	2.2 (0.59-8.43)
Normal/Overweight to Obese	2.0 (1.00-4.14)	6.6 (1.68-25.86)	1.1 (0.15-8.42)
Overweight/Obese throughout	1.4 (0.49-4.16)	1.0 (0.10-9.77)	1.4 (0.22-8.61)

Race and BMI change interaction term significant (p<.0001). Model was adjusted for all variables that are confirmed or suspected risk factors for breast cancer: age (continuous), race/ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic and Other race), education (less than high school education, high school graduate and college education), marital status (married or living with partner Yes/No), age at menarche (continuous), age at menopause (continuous), smoking (smoked at least 100 cigarettes in life Yes/No) and total cholesterol (mg/dl).
