[Birth weight of newborn infants in relation to body height and body weight of parents with special reference to duration of pregnancy].

Using the data of the 1985 GDR somatogram standards (birthweight percentiles calculated from 51,570 liveborn singletons) the impact of parental weight and length on the birthweight were calculated. Peristatic factors in combination with the genetic 'anlage' act first of all via maternal weight. Body height and/or length of mother and father are more representative for the genetic constitution. Their impact on neonatal weight seems to be less significant, however statistically calculable. The paternal 'anlage' is relatively modified by the intrauterine environment (maternal constitution).
