Analyses were made of the prevalence of anemia among women engaged in work on Japanese farms. In most cases this anemia was diagnosed hematologically as iron deficiency anemia. During the course of the study the local population became more aware of the situation and the eating habits began to improve, resulting in a lowering of the number of cases and the severity of the anemia found. Results indicated that the incidence of anemia was significantly lower among these workers than in the general population. The averages of about 2,000 female farmers increased from 12.04 grams per deciliter (g/dl) for 1967 to 1968 to 12.85g/dl for 1976 to 1977, with a steady rise in hemoglobin concentrations in recent years. The incidence of cases below 12g/dl dropped from 43.8 percent to 16.1 percent during this time period. Those below 11g/dl dropped from 14.1 to 5.8 percent. As regards the changes in eating habits over these years, the intake of animal protein, animal iron, iron per unit energy, vitamin-A, vitamin-B2, lysine, and valine increased which carbohydrate and phosphorus concentrations decreased.
