The Health Survey of the Peasants and the Fishermen Part 1. Aspects of the Blood Examinations

The health survey of peasants and fishermen were carried out in 1968 at two districts. The one is T-area which has a charactor of a farm village. The other is K-area which has that of a fishing village. Farm houses from both T-area and K-area and fishing houses from K-area were sampled. Farm houses sampled from T-area is abbreviated as T and fishing houses sampled from K-area as K(1) and farm houses sampled from K-area as K(2). The blood examinations of peasants and fishermen were conducted for this health survey. The specific gravity of the blood, the density of the serum protein, the hemoglobin level and the concentration of the serum iron were measured. 1) No significant differences exist between the means of the specific gravity of blood of the husband in K(1) and T, and also between that in K(2) and T, and so do among that of housewife in K(1), K(2) and T. 2) Significant differences exist between the means of the density of serum protein of husband in T and K(1), and so do between that of T and K(2). 3) Considering from the point of means and ratio of people whose blood is abnormal against people examined. Following results were oftained. The specific gravity of the couple in T is better than that of the couple in K(1) and K(2). The density of serum protein of the couple in K(2) is better than that of the couple in T and K(1). The hemoglobin level of the couple in K(1) is better than that of the couple in T and K(2). 4) It is recognized that about fifty per cent housewives have serum iron deficient anemia. 5) I devised the nomogram showing differences of patterns which indicate the values of the blood specific gravity, the hemoglobin level, the density of the serum protein, and the concentration of the serum iron, in the inhabitants of the different areas. This monogram has a convenience that we can easily detect whether mean obtained from blood test show over standard level or not at a glance. 6) The hemoglobin level correlate with the specific gravity in the blood of husband in T (γ=0.89). Correlation can be found in the case of housewife in T (γ=0.96). 7) The Hemoglobin level of husband correlates with that of housewife (γ=0.51). 8) It is recognized that the ratio of family in which both husband and wife indicate low value of blood examinations against total family number indicating low value of blood examinations shows high value (70 per cent in T)
