Multivariable models of parity and incident diabetes

	Incident diabetes	Model 1: age and race	Model 2: potential confounders*
Nulliparous	33	1.0	1.0
1–2 live births	99	1.09 (0.73–1.62)	0.96 (0.63–1.47)
3–4 live births	60	0.95 (0.62–1.46)	0.86 (0.54–1.35)
≥5 live births	23	1.23 (0.72–2.10)	0.95 (0.54–1.67)

Data are n or HRs (95% CI). Cox proportional hazard models were used.

*Model 2: age, race, marital status (4), income (3), education (3), height (in centimeters), alcohol yes/no, clinic (4), and smoking (3).
