Abstract
A study of occupational problems in dairy farmers was conducted. The cohort consisted of 25 couples selected from a group of 300 adult dairy farmers living in Kuzumaki District, Japan. The mean age of the subjects was 42 to 43 years. Blood samples were collected during the winter season (late November), spring (mid June), and summer (late August) over a three year period. These were assayed for red and white blood cell counts, hemoglobin, hematocrit, serum iron, serum-glutamic-oxaloacetic-transaminase (SGOT), serum-glutamic-pyruvate-transaminase (SGPT), alkaline- phosphatase, albumin, and total protein. Blood pressure was also measured. Mean systemic and diastolic blood pressures were higher in both sexes during the winter than in other seasons. The difference was significant. Red blood cell counts, hemoglobin concentrations, and hematocrit values were significantly lower in the summer than at any other time. White blood cell counts, SGPT, and SGOT tended to increase in both sexes more in the winter than in the spring or summer. Serum total protein concentration was significantly higher in the winter and serum albumin was significantly lower than at other times. Serum iron concentrations were lowest in mid June. The authors conclude that hypertension in dairy farmers tends to increase in the winter and anemia has a tendency to increase in summer. Variations in serum protein concentration are affected by work load and reactions toward changes in hemoglobin concentration.
