RRs of type 2 diabetes for 2 categories of breakfast consumption¹

	Regular breakfast consumers: 7 times/wk (n = 1074)	Irregular breakfast consumers: 0–6 times/wk (n = 486)	P value
Person-years	197,294	62,894
Age RR (95% CI)	1.00 (Reference)	1.39 (1.25, 1.55)	<0.001
Multivariate RR (95% CI)2	1.00 (Reference)	1.34 (1.20, 1.50)	<0.001
Multivariate RR (95% CI)3	1.00 (Reference)	1.28 (1.14, 1.44)	<0.001
Multivariate RR (95% CI) + BMI4	1.00 (Reference)	1.20 (1.07, 1.35)	<0.01

¹RRs (95% CIs) were derived from Cox proportional hazards models.

²Adjusted for age (in mo), family history of type 2 diabetes (yes or no), alcohol intake (0 to <5, 5 to <15, or ≥15 g/d), physical activity (1 to <3, 3 to <9, 9 to <18, 18 to <27, or ≥27 metabolic equivalent h/wk or missing category), menopausal status and hormone use (premenopausal, postmenopausal and never used hormones, postmenopausal and current hormone users, or postmenopausal and past hormone users), and smoking status (never, past, current 1–14 cigarettes/d, current 15–24 cigarettes/d, current ≥25 cigarettes/d, or missing category).

³Adjusted as for the previous multivariate model plus energy intake (kcal/d, continuous), cereal fiber intake (quintiles, g/d), and the Alternative Healthy Eating Index 2010 (quintiles or missing category).

⁴Adjusted as for the previous multivariate model plus BMI (in kg/m²; <21, 21–22.9, 23–24.9, 25–26.9, 27–29.9, 30–32.9, 33–34.9, 35–39.9, or ≥40); the percentages of observations assigned to missing categories were as follows (baseline/follow-up): 0.25%/0.35% for smoking, 6.4%/7.6% for physical activity, and 0.37%/0.35% for the Alternative Healthy Eating Index 2010.
