In order to study whether there is any relation between the cause of anemia in rural women and environmental factor from the epidemiological standpoint, we have followed up the seasonal change of the blood properties (GB, Hb, Ht, R, Serum iron) of 3 groups of women in different working and living circumstances. The results revealed a remarkable tendency to increase the values of the blood properties excluding serum iron in winter and to decrease in summer. The degree of seasonal change was found to be greater in rural women than that in factory workers. And among the factory workers, the married had more change than the unmarried, the rural residents than the urban. And among the rural women, only the establishmental gardeners who were especially busy in winter showed a tendency to decrease the values of the blood properties in winter. From these data, we can see that the seasonal change of the burden of agricultural work and the change of dietary life actually have direct influence on the change of the blood properties.
