Patterns of Sexual Dimorphism from Birth to Senescence
Holle Greil
Sažetak
Sexual dimorphism is expressed as median of the female values in percent of the median of the male values, of 4
length measurements, 3 circumferences, and 5 measurements of corpulence respectively fat. Data were obtained from a
cross-sectional sample of more than 41.000 German subjects, aged from birth to age 62. The pattern of sexual dimorphism
is similar in the length measurements. Girls are shorter at birth, but they increase in length at higher rates than
boys and even temporarily overgrow the boys up to age 12. Thereafter, males show an obvious growth advantage leading
to some 6 to 9% more length in adult males. In contrast, female circumferences are always smaller, from birth to senescence.
Though, the differences between the sexes are low in circumferences, up to age 13, sexual dimorphism increases to
17% in the thoracic circumference at adulthood. Sexual dimorphism in weight and BMI is comparably with that in
length measurements while subcutaneous fat and total body fat content are always higher in females. The results highlight
that sexual dimorphism develops at different pace in the various components of the body and that it associates with
a sex specific growth tempo.
