Secondary data analyses from the Longitudinal Study of Australian Children Kindergarten cohort were performed to understand any alterations in pubertal timing in Autism Spectrum Disorder (ASD) in a population sample. Timing of parent-reported pubertal events (ages 8–9, 10–11, 12–13 years), and self-report (14–15 years; N = 3454 no ASD, N = 94 with ASD) included breast development, menses, skin changes, growth spurt, body hair, deepening voice and facial hair. Survival analyses and Cox regression controlling for covariates showed no evidence of altered pubertal onset amongst males with ASD. In contrast to some past studies, there was also no difference in pubertal timing in females with ASD. These exploratory findings suggest typical puberty timing in a population representative group of young people with ASD.
