34 kilos (about 75 pounds) is pretty thin. The average 12-year-old is around 5 feet tall, in which case being 34 kilos would be severly underweight. (BMI / Body Mass Index would be 14.6, and 18.5 is the lowest "healthy" weight BMI you can have.) Assuming she was about 4'6'', then that would be healthy. Between 4'6'' and 5', she would be considered to be "underweight".
im 12 am 45kilos and 165cm tall (5ft 5), so its ok as long as you are not undereating
