—We have reported that maternal growth during adolescent pregnancy, as indexed using the Knee Height Measuring Device, is associated with greater maternal weight gain during pregnancy and increased maternal accrual of subcutaneous fat.1,2 Changes such as these typically are associated with increased infant weight at birth, as opposed to the birth weight reductions we have observed for still-growing gravidas (about 150 to 200 g birth weight). During pregnancy, we use the Knee Height Measuring Device to index maternal growth because serial measures of stature are an insensitive indicator of growth.2
