An intriguing social gradient of menarcheal age was found among girls from twelve different social groups defined by father’s occupation and occupational status. Menarcheal age was also found to depend upon parental education and family size

STATURE AND RELATIVE BODY WEIGHT OF; POLISH CONSCRIPTS IN 1976 AND 1986: SECULAR CHANGES AND URBANIZATION - DEPENDENDENT GRADIENT

Statural gains were of similar magnitude, ca. 2.0 cm., in each of the five categories of urbanization defined by population size of the locality of habitation. As a result, the regular urbanization-dependent gradient in stature, first detected in the 1976'cohort, reappears in little changed form 10 years later. No significant secular changes and no regular gradients can be seen in weight-for-height
