I am interesting about it. Does Aspies and other people with ASD/PDD have lower birth weight than average population? Does their birth weight to length ratio tend to be lower than in average populations?

A baby length and height percentile chart in Polish

I had body birth weight 2150 g and the length was 53 cm. So I was well below 5th percentile (really low). My sister had birth weight 2650 g and body length 53 g, so she also has low result (slightly below 10th percentile).

I don't know how much exactly but I know that I was too small when I was born by seeing pictures of myself from that time and hearing about it from others.

I don't know the exact stats, but I was just above average sized baby.

My guess is that if you compare newborn babies by weight per body length you will find that MOST short babies will have fewer onces of weight per inch than longer babies do. Tall adults have more weight per inch of stature than do short adults. And 100 foot long crab boats weigh around 100 tons (one ton per foot of keel length), while 1000 foot long aircraft carriers tend to displace around 100 thousand tons (100 tons per foot of keel length).

So if you're gonna compare babies by weight/size wouldnt it make more sense to plot their body weight,not against body length, but against the CUBE of their body length?.Your weight is proportional to your volume, not to your linear height.

Lets say its fish. You wanna know if fish B is scrawnier than fish A. Fish A is X inches long and weighs Y number of pounds. Fish B is 2X inches long. If it had the overall same proportions as fish A it would weigh, not 2Y pounds, but 8Y pounds (because its width, and height from keel to upper deck would also be twice that of fish A, giving fish B eight times the volume of fish A). So if fish B is only 7 times as heavy as fish A then you know its less robust in body proportions (scrawnier).

I had relatively long body (53 cm) and small weight (2150 g) as a newborn. I heard yesterday from my grandmother that my mother had birth weight: 2800 g and body length: 56 cm. It is sligtly below 5th percentile on the graph! My sister had 53 cm and 2650 g - she is slingtly below 10th percentile.

My father had probably low birth weigth, but I do not know about his length. He may also be below 10th percentile... Interesting. Maybe it is a sign that my PDD is genetic or has genetic component in it?

I suppose that my mother and sister have some "atypical" traits of mentality. Maybe they have a broader phenotype/traits of a PDD? But it is interesting that I, my mother and sister have low results according to the graph (<10 centile - sister, I and mother even below 5th percentile). Maybe it is a hereditary trait in this case?

So very low birth body weight to length ratio is really popular among members of this forum, at least so far. It appears to be a PDD trait.

I do not know what was the weight and lenght of the body of my brother and father. Mother and sister are significantly below average. Father may be also - I must check it. I should also know the weight and length of the body of my brother. I think that my brother may be other than rest of the family - even above average. He also looks most NT from my family. In my family there is not so good atmosphere - maybe it is because of some sort of neuropsychological disorder associated with poor weight/lenght birth ratio? My mother had also an illness before my birth and I had dystrophy after it. But my Apgar score was 10. I was not a "preemie". I had positive and negative "traits". My sister looks somewhat "strange" to me, she said once that something like she has not need of being loved or acceopted, her voice is somewhat "childish" although she has above 13 years old. I think that she (or maybe even my mother) may have some sort of subclinical AS (which means that she is an "Aspijka" (nice, cute Polish word for a female with AS or similar condtion)), rather not clinical AS. Women with AS from Polish AS forum may look for me not so "strange" as she.

Charts:

http://happybabyusa.files.wordpress.com ... -chart.jpg

I had 2150 g on birth - it is below 2nd percentile on this chart... But 53 cm is above 85th percentile.

My mother has 56 cm on birth according to my grandmother, it is qute well abouve 98th percentle on length chart for girls... Her weight (2800 g) appear to be about 15th percentile (quite low). Maybe in my family there is a genetic syndrome?

http://happybabyusa.files.wordpress.com/2011/05/growth-chart.jpg (I have a hope that the link will be not broken :) )

53 cm for a boy appears to be about 85th - 97th percentile... And with birth weight below 2nd percentile it looks pretty "aucorigic"... I do not know what was birth body length of my father. But it was probably (maybe even quite much) above 51 cm and birth weight was just 2800 g (slightly bove 10th percentile). His siblings (boy and girl) have birth weight above 3000 g (rther above 25th percentile), as I listened.

There should be 68,2% chance for a newborn to have body weight or length wich differs less than one standard deviation from average value (50th percentile). Then weight or length should be between 16th and 84th percentile. If we make something like intelligence quotient for birth weight and length...

Image

53 cm - appers to be between 85th and 97th percentile for boys (in the range between one and two standard deviations (SD) from average) - "BLQ" (birth lenght quotient) would be about 116 - 128 for me. 2150 g - it is below 2nd percentle for boys ("BWQ" - birth weight quotient) would be below 70 (maybe about 65, something like "mild intellectual disability" range). BLQ/BWQ split will be more than 50 in my case.

http://happybabyusa.files.wordpress.com/2011/05/growth-chart.jpg

For my sister (2650 g, 53 cm) BWQ would be about 80 (about 9th percentile, something like "borderline intellectual functioning" range) and BLQ about 125-130 (95th - 98 th percentile, very high). Split - about 45 - 50 (really large).

My mother's weight (2800 g) appear to be about 17th percentile (BWQ about 88). Her body lenght - very large - 56 cm is well above 98 th percentile (BLQ above 130). Split also large - more than 40.

My birth weight was around 5 lbs (or 5 1/2, I can't remember exactly), and not premature.
