I can never fathom why some people feel the need to be so harsh on threads about children's weight. hmm\
Because some people think that being overweight is a moral failing and utterly despicable. They look at BMI as some kind of holy grail of health when it's simply a population based measurement that breaks down at the individual level.
It's entirely possible to be overweight and very healthy. Especially if you have a large frame and are athletic. My brother, my son and all of my male cousins and uncles (not to mention my aunts and myself as well) rarely manage to get into a healthy BMI, and even then we are starving ourselves to do it. We are all athletic (my mother and two of my cousins competed on the national level in several sports when they were in their twenties), we all exercise intensely 5+ hours a week, we eat healthy (actually we aren't what you would describe as big eaters), We all have wide shoulders, wide hips and an torsos's and a lot of muscle in our arms and legs. My uncles and male cousins are all 6 ft 4 and up. My son is 125 cms at 4 years old. My mom is 5'10 as are her sisters. I'm the shorty of the family at 5'6 (thanks Dad) and have inherited my paternal grandmothers hourglass figure and D boobs as opposed to my mothers families B cups and rectangular figure. But I'm still athletic and gain muscle easily.
When I was in my late teens and early twenties I did not eat. For days the most I would have was a bit of white rices and water. My GP was very worried because he knew I wasn't eating and that I was overexercising, but my BMI never got low enough to qualify for help or ED counseling. The lowest I was after puberty was 9 stone 3, which is a BMI of 21. I felt horrid, tired, cold, I was missing periods, my joints hurt, etc etc. Alas, BMI of 21 was the lowest I could go.
I'm now a BMI of 27 and I feel great (except my B12 and iron were low lately, but I'm taking supplements now), I'm strong, fit and I eat healthy. I'm sure everyone on here would call me chubby, although I don't have a tummy or any cellulite, but my GP says I'm the epitome of health.
My DS waffles in and out of overweight on the child's BMI. He gets chubby, has a growth spurt and slims right out, and the cycle continues. His GP is thrilled with his health, and says he'll be a rugby player someday. LOL. When I expressed concern about his BMI she laughed and told me to ignore it.
Threads like this drive me nuts. BMI is a population measure. If you receive one of the letters home and you don't think it applies to your DC, then go talk to a GP and get an individual opinion. BMI is not a measure of health.
