This is so, for instance, among the Pueblo Indians, and among the Indians of Mexico.

Similar care is taken in the Carolines and the Gilbert Islands and in many other regions all over the world.

In some places, women are secluded during pregnancy, and in others are compelled to observe many more or less excellent rules.

It is true that the assigned cause for these rules is frequently the fear of evil spirits, but they nevertheless often preserve a hygienic value.

In many parts of the world the discovery of pregnancy is the sign for a festival of more or less ritual character, and much good advice is given to the expectant mother.
The modern Musselmans are careful to guard the health of their women when pregnant, and so are the Chinese.[6] Even in Europe, in the thirteenth century, as Clappier notes, industrial corporations sometimes had regard to this matter, and would not allow women to work during pregnancy.
