he medical community is divided as to what is causing the spike in early puberty among girls. Factors including blue light exposure, the use of hand sanitiser and obesity have all been cited. Medical professionals across the world are working to understand the root cause.
A recent study, carried out by a team of researchers in Seoul, South Korea in August 2022 revealed that the number of girls starting their periods before the age of eight had more than doubled since 2016, to 166,645 girls by 2021. In Germany, as reported in the New Scientist, a group of researchers carried out a representative study in one clinic. The findings showed that from 2015 to 2019, the number of girls referred for precocious puberty (PP), or early onset (as it is sometimes referred to as), had remained a constant at around ten cases a year. Then Covid-19 hit, and by 2020 that figure had more than doubled, and by 2021, it had risen to 30 total cases.
