CONCLUSIONS 
1. The Filipino pelvis is of a type different from either the 
white American or the Negro pelvis, and its average normal 
measurements are similar to those of the generally contracted 
pelvis of the white American. 
2. The index of the posterior pelvic plane in cases of con- 
tracted intertuberal diameter is important in the determination 
of the probable outcome of labor. 
3. Contracted pelvis, except in cases of osteomalacia, is rarely 
an indication to Cesarean section among Filipino women. 
4. There is practically no difference in the measurements of 
the pelvic diameters of multiparz and primapare. 
5. The newborn babies of multiparze are longer and heavier 
than those of the primipare. 
6. The babies of mothers who stayed in the hospital for one 
or more weeks before delivery are heavier than those whose 
mothers entered the hospital at the time of labor. 
7. The male babies are in greater number and are longer and 
heavier than the female babies. 
8. Labor is longer in primipare than in multipare.
