8 year old girls under 20 kg or over 33 kg and 8 year old boys who weigh less than 21 kg or more than 33 kg may want to consult with a doctor. The American Academy of Pediatrics recommends that children who's weight is outside the 5th or 85th percentiles seek professional advice to determine if further evaluation is needed2.
Around the age of 8, children's growth slows down compared to their early years. On average, an 8-year-old weighs approximately 26 kg for boys and 26 kg for girls based on CDC growth charts1. At this age, boys and girls might start showing more noticeable differences in weight and height, influenced by factors such as genetics and hormonal changes. It's essential to promote positive body image and focus on overall health rather than weight alone, emphasizing the importance of a balanced diet and regular physical activity.
