Items such as the growth curve with the calculated midparental height
, number of prior rapid strep tests that were positive or negative, or the number of times an asthmatic child has been prescribed an oral steroid are all display uses of the EHR that lend themselves to sharing with a curious or worried parent.
Midparental height (MPH) SDS and A height SDS (HSDS MPH SDS) were also assessed.
05# MPH: midparental height, BMI: body mass index, GHD: growth hormone deficiency, IGF/1: insulin/like growth factor 1, FAT: fat mass, FFM: fat free mass, PMM: predicted muscle mass, TBW: total body water, and W/HtR: waist height ratio.
To calculate the midparental height for a girl, we subtract 13 cm (5 in) from the father's height and average it with the mother's height.
However, if the projected height differs from the midparental height by more than 5 cm, a variant growth pattern or a disease condition should be considered.
Apart from measuring the height, and calculating the midparental height, an endocrinologist takes measurements of various body parts to determine if some body parts or segments are growing disproportionately.
After controlling for midparental height
, members of the IVF group were considerably taller than the naturally conceived children.
The standard charts compare the individual to a North America data set, but midparental height gives a sense of what's normal within a particular family
The child's target height is within 4 inches above or below the midparental height (plus or minus 2 standard deviations), he said.
For a girl, subtract 5 inches from the father's height at age 18, add that to the mother's height at age 18, and divide by two to get the midparental height.
For the general population, the expected future height falls within two standard deviations of the midparental height.
The mechanism of action for growth velocity patterns after the discontinuation of steroid use is not well understood, but by the end of the study most of the children were on track to achieve their normal height based on midparental height, Dr.
