Associations between cumulative dietary intakes over initial 3 years of follow-up (1996, 1997, 1998; youngest dietary data for each girl) and risk of BBD in young women: dietary intake means by BBD status and odds ratios (OR)

	Never reported BBD (n = 6950)	Biopsy-confirmed BBD cases (n = 112)	Age–energy-adjusted			Multivariable-adjusted
	Mean	Mean	OR	(95 % CI)	p	OR	(95 % CI)	p
Vegetable protein (10 gm/day)	2.41	2.38	0.85	(0.55–1.33)	0.48	0.86	(0.55–1.34)	0.50
Vegetable fat (10 gm/day)	3.40	3.26	0.72	(0.53–0.98)	0.04	0.72	(0.52–0.98)	0.03
Peanut butter and nuts (servings/3 days)	0.52	0.38	0.56	(0.36–0.88)	0.01	0.56	(0.35–0.87)	0.01
Beans, lentils, soybeans (servings/3 days)	0.24	0.24	0.94	(0.55–1.61)	0.83	0.95	(0.55–1.62)	0.84
Corn (servings/3 days)	0.40	0.37	0.69	(0.35–1.35)	0.28	0.73	(0.37–1.43)	0.36
Total servings per day of peanut butter, nuts,  beans, lentils, soybeans, corn	0.38	0.33	0.32	(0.13–0.79)	0.01	0.33	(0.13–0.82)	0.02

Multivariable-adjusted models further include childhood adiposity, age at menarche, adolescent alcohol intake, and pregnancy (ever). The mean age, for the cumulative 1996, 1997, and 1998 surveys, was 12.8 years. Categorical food analyses provided similar results: Peanut butter and nuts, 1 + serving/(3 days) vs none, OR = 0.44, 95 % CI 0.20–0.99; Beans, lentils, soybeans 1 + servings/(3 days) versus none, OR = 0.61, CI 0.24–1.57; Corn 1 + servings/(3 days) versus ≤3/month, OR = 0.79, CI 0.34–1.82
