Instructions:
Background For adults, the body mass index limits for overweight and obesity are straight forward (overweight = BMI > 25 and obesity = BMI > 30). For children this is much more complicated as the limits vary a lot depending on age. This calculator uses the US guidelines that are based on fixed percentiles from a large reference population. A BMI of 20 indicates obesity in a 6 year old girl, whereas it would represent healthy weight for a 13 year old girl. However, as growth of children varies, the final evaluation should always be based on a several factors including physical growth, muscularity and subcutaneous fat deposits. The calculator also includes the possibility to evaluate height in relation to age. If the child/youth scores in the high percentile range on height (above average) this could indicate that physical development is ahead of chronological age. As higher BMI is expected with increasing age (above age 6), this information can assist in a qualified evaluation of BMI. References

It is important to understand that the calculator considers an ideal (average) variant of weight of a child. If the body mass have +500g every month or has not changes at all, in this case, of course, it is desirable to consult with the personal doctor, because the Nation's Health is most important. http://nation-health.blogspot.com/ |

this calculator says that anything under 15.4 is underweight, and that anything over 22.5 is overweight. However, the other one says that anything lower than 18 is underweight, and anything over 25 is overweight. talk about inaccurate. |

Hello is a bmi of in the 21 range too high. under 25 is good for adults but it's different for kids. that's why a lot of people bother that their child is at a healthy weight but they don't know that it's different for kids and its even different for kids who are at different ages. The reason why it's different for kids is because of the amount of body fat that changes by age and the difference of body fat between boys and girls. The calculator involves percentiles. Percentiles tell you which place your bmi is compared to the people who are at your age and gender. 1st to 4th percentile is the underweight category. 5th to 84th is healthy weight. 85th to 94th is overweight. 95th to 100th is obese. There may be children who are thin who are still told that they're overweight or obese if they're very young children. There are CDC percentile charts that tell you what bmi is in which category for your age. The charts are like graphs and there is a chart for boys and girls. They are used for kids who are at least two years of age but less than 20 years old. If you take a look at the charts then you'll understand how they are graphed. The definitions have also been changed. It's still called underweight for children and adults but it's called healthy weight as Normal for kids, at risk of becoming overweight as overweight for kids, and overweight as obese for kids. The reason why they say overweight for children at risk of becoming overweight is because you would be at risk of becoming an overweight adult because overweight children are likely to become overweight adults. And they say overweight for children as obese because obese children have a high chance of becoming at least overweight that's high enough to be told that he or she will become at least overweight |

I think this is so very sad to see young kids saying they hate themselfs by doing their body weight with this tool, where is someone to chat them through it to try to help, they shoudln't hate themself because of this u change ur whole life easp from 10 to 20 reading this has made me not want to go onto these sites to read children hating themselfs their bodies, I don't see how they can possible be rated on some tool on a computer every child is different and their weight changes why is there no one to talk to them to help, don't leave them hurting like this i think this is just awful and won't go on this again ! Kids DON'T HATE YOURSELF OVER WEIGHT IT CAN CHANGE U CAN CHANGE IT , AND IT JUST MAY ON ITS OWN Im 40 and i have gone up and down since a child my weight is normal and I had a weight problem as a child both low and high , so don't worry !!!! love yourself the best u can thats the best way to deal with any problem Take care CJ |

The calculator has now been been updated with the latest terminology used (thanks Tracy). The percentile limits used have not changed, but the definition changes are: Underweight -> Underweight Normal weight -> Healthy weight Risk of overweight -> Overweight Overweight -> Obese |

Tracy - Thanks for adding your comment. This calculator is precise and based on the CDC growth charts. I have responded to your email, so we can clear out any misunderstandings. |

It seems to me you can determine it just looking at the child. If a child or anyone else has weight problems it can be easily noniced. I also know that there are some formulae which calculates the normal weight. I've read about it in a book which I found at rapidshare SE http://rapidpedia.com . It was about healthy food. Just eat healthy food and You'll never bother about your weight. |




Lol hhaha im under weight WOOO! go me
