MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The motivation for this study is the apparent accelerated maturity in children in the United States.
We previously demonstrated that skeletal maturity (bone age) is more advanced in today’s children compared to children born in the first half of the 20thCentury (Duren et al., 2015).
n the current study (Boeyer et al., 2018) we show that a significant component of this advanced maturity status is the timing of epiphyseal fusion. In our study, nearly half of the epiphyses of the hand and wrist began or completed fusion significantly earlier in children born after 1995 than those born in the early part of the century, with differences as great as six to ten months for some bones, and mean differences on the order of 4 months in boys and 6 months in girls.
