Abstract

PIP: A correlation study was undertaken in 2 districts of Kenya to ascertain the relationship between nutrition and health of workers and their productivity. 269 road workers were examined. Blood was taken for hematological examination; urine was tested and stools collected for parasitical study; dietary information was collected; and work output studies conducted. The data show evidence of low calorie reserves and undernutrition in a large percentage of the workmen. Hematocrit and hemaglobin levels were inadequate in more than 30% of the men at 1 of the 2 sites, indicating the presence of parasitic infection-induced anemia. Stool samples confirmed these diagnoses. There was a consistent and highly significant relationship between low weight-for-height and low productivity. Dietary intervention was tried in 1 of the 2 following ways: 1) calorie supplementation; or 2) iron supplementation. Body weight increased in the calorie supplementation group and hematocrit levels increased for those receiving iron. It is concluded that the provision of food at the worksite would benefit workers both physically and psychologically. Without such intervention, economic development will be difficult to achieve.
