Body mass index, overweight and obesity and the association (β* and P-value) between BMI z-scores and the timing of adrenarche, thelarche and menarche in Bangladeshi, First-Generation, Second-Generation and white British girls in the ABBY Project, derived from Weibull Models.

	N	Body Size		Pubertal Outcomes
		BMI	Overweight/Obese	Adrenarche		Thelarche		Menarche
		Mean (SD)	%	β	P	β	p	β	p
Overall	410	18.2 (3.9)	25%	0.08	0.16	0.29	<0.001	0.10	0.34
Bangladeshi	165	16.4 (3.4)	8.4%	0.09	0.37	0.48	0.001	0.38	0.08
First-Generation	39	19.6 (4.3)	35%	0.28	0.33	0.02	0.92	−0.23	0.50
Second-Generation	156	18.8 (3.6)	32%	0.07	0.49	0.06	0.59	−0.09	0.61
White British	50	19.9 (3.8)	48%	0.37	0.18	0.82	0.01	0.39	0.30

*a positive β represents an earlier age at pubertal outcome per unit increase in BMI z-score.
