Hazard ratios for early type 2 diabetes according to quartiles of age at PHV in 30,697 Swedish men followed for a mean of 30.7 ± 7.5 years after age 30

Age at PHV quartiles	Range for age at PHV	Events	HR (95% CI)
			Base model	Adjusted for cBMI
Q1 (n = 7674) vs Q4	9.3–13.4	317	1.97 (1.63, 2.38)	1.78 (1.47, 2.16)
Q2 (n = 7674) vs Q4	13.4–14.1	242	1.50 (1.23, 1.83)	1.46 (1.20, 1.79)
Q3 (n = 7675) vs Q4	14.1–14.8	205	1.26 (1.02, 1.54)	1.24 (1.01, 1.52)
Q4 (n = 7674)	14.8–17.9	162	Reference	Reference

HRs (95% CI) for type 2 diabetes for Q1–3 according to age at PHV with Q4 as reference were calculated using Cox proportional hazards regression. The base model is adjusted for birth year and country of birth, while the adjusted model also includes childhood BMI as a covariate. Cases of type 2 diabetes diagnosis n = 926, total number in analysis N = 30,697

cBMI, childhood BMI at age 8
