[Effect of work performed by pregnant women on birth weight and fetal hypotrophy].

The studies have been aimed at evaluation of the effects of occupational and non-occupational work on foetal maturity and foetal intrauterine hypotrophy. The studies involved 17,134 women who gave birth to 17,324 newborns. The parturients have been divided into 5 groups: I--mental workers, II--physical workers, III--housewives, IV--farmers, V--peasant working also as labourers. The highest percentage of low birth weight newborns was found in peasant-labourers--16.96, housewives--12.42, and physical workers--11.77.
