Change in pubertal timing categories based on Year 1 reports versus Year 3 reports

	Pubertal Timing Year 3 Counts

Pubertal Timing Year 1 Counts	Early	On-Time	Late	Total
Early	18 (8.8%)	7 (3.4%)	0 (0%)	25 (12.3%)
On-Time	14 (6.9%)	119 (58.6%)	9 (4.4%)	142 (70.0%)
Late	0 (0%)	16 (7.9%)	20 (9.9%)	36 (17.7%)

Total	32 (15.7%)	142 (70.0%)	29 (14.3%)	203 (100%)

Note. 22.7% (N = 46) demonstrate change in timing categories; chi-square comparison test indicates actual counts differ from expected counts: χ²(4) = 125.3, p < .001
