The number of girls diagnosed with precocious puberty increased during the COVID-19 pandemic was
most likely due to obesity - increased screen time and less physical activity.
Precocious puberty is when children's bodies begin to change into adult bodies too soon. They start to develop physical changes before the age of 8 such as breasts buds in girls and bigger testes in boys.
Girls diagnosed with precocious puberty during the COVID-19 pandemic tended to have higher body mass index (BMI) scores than girls who did not. These girls spent an average of 2 hours per day using electronic devices, and 88.5% of them stopped any physical activity.
