Comparison of adult outcomes between highly-troubled adolescent groups

	Top 25% early maturers/>=5 adolescent outcomes
	Early		On-time
	Mean	SD	Mean	SD	Mean ratio	(95% CI)	P
Crime outcomes	0.4	(0.7)	0.5	(0.6)	0.7	(0.3–1.7)	0.45
Substance outcomes	0.1	(0.4)	0.3	(0.7)	0.3	(0.1–1.3)	0.10
Education/employment outcomes	1.9	(1.1)	1.9	(0.9)	1.0	(0.7–1.5)	0.92
Sexual outcomes	1.5	(1.3)	1.5	(0.8)	1.0	(0.6–1.7)	0.91
Psychiatric outcomes	0.6	(1.1)	0.6	(0.7)	1.1	(0.4–3.3)	0.86
Total adult outcomes	4.5	(2.1)	4.7	(0.2)	1.0	(0.7–1.3)	0.75

Groups defined based upon the upper 25% for early maturers on a scale of total adolescent problems. This percentile corresponded to displaying 5 or more (upper 25%) adolescent outcomes. This cut-off included 31 early maturers and 109 on-time maturers. Mean ratios were derived from exponentiated standardized regression coefficients from Poisson regression. Mean ratios above 1.0 indicate higher levels in early maturing group. Similar results were obtained when looking at the top 50% of early maturers on total adolescent problems and those results are available from the first author by request.

SD=standard deviation; 95%CI=95 percent confidence interval.
