adult height estimation at menarche - Sexual Heights with Lysa Thatcher (1978)


Disregarding age, 58% of all height predictions were within cm (1 in), 85% of all predictions were within 5 cm (2 in), and 96% of all predictions were within cm (3 in) of adult height for boys. The percentage of adult height attained at menarche correlated significantly with the age of menarche. Regression equations and standard errors are presented to aid in the prediction of the age at menarche from other variables related to menarche.

An alternative protocol predicts adult height from CA, height and weight of the child and midparent height, 27 Current height is then expressed as a percentage of predicted adult height to provide an estimate of maturity status. Among youth of the same CA, the one closer to adult height is more mature than the other who is further from adult. Jul 17,  · Use this height predictor to estimate how tall your child might be Predicted heights are usually within 4 inches, taller or shorter, than actual adult height. Medical conditions and other factors.

In contrast, lung volume increases in males continue throughout puberty and beyond the point at which final adult height is reached. We interpret the differential relationship seen at 15 years in this study in the context of most females having completed menarche by this age but a sizeable proportion of males being in midpuberty. In the mothers, early age at menarche was linearly associated with reduced adult height (by cm/y; p, ), but increased adult body weight ( kg/y; p, ) and BMI ( kg/m2/y; p, ; Table 1). Compared with the oldest menarche quintile (15 y old), those mothers in the earliest menarche quintile (11 y) had a 5-fold.

Jan 08,  · Mediation analysis was performed using G-computation to estimate the direct effect of age at menarche and the indirect effect of body composition. Among young adult women, age at menarche. BODY SIZE factors, including height, weight, body mass index (BMI), and body fat percentage, have long been found to be strongly associated with the onset of menarche. The relationship of the growth spurt in height and weight to menarche has long been studied. A more classic theory by Simmons and Greulich 10 suggests the existence of synchronization of age at menarche and skeletal.
