Circadian phase delay is observed at which age according to the provided material?

Circadian phase delay means the internal clock shifts to a later time, so sleep tends to occur later and wake times may be later as well. As children grow, the timing of melatonin release and the alignment with daytime demands can move toward later evenings. In the material you’re studying, this delay is reported around age ten, suggesting late childhood shows the beginning of a shift toward later sleep timing. Newborns and very young infants don’t have a stable circadian phase yet, so a circadian phase delay isn’t described at 16 weeks. Adolescence is when the delay becomes more pronounced, but the material specifies ten years as the observed age, making that the best match for this question.
