Vitamin B12, folic acid, ferritin and haematological variables among Thai construction site workers in urban Bangkok

Serum vitamin B12, folic acid, ferritin and haematological variables were investigated in eighty-seven male and nineteen female construction site workers in Bangkok. Haemoglobin concentration, haematocrit and MCHC were found to be higher in male than in female workers. Serum ferritin was slightly hi...

Summary:Serum vitamin B12, folic acid, ferritin and haematological variables were investigated in eighty-seven male and nineteen female construction site workers in Bangkok. Haemoglobin concentration, haematocrit and MCHC were found to be higher in male than in female workers. Serum ferritin was slightly higher in males than in females. Serum B12 was found to be higher in male than in female workers and serum folic acid level were significantly higher in female than in male workers. Vitamin B12 deficiency was found in 2.3 per cent and folic acid deficiency in 6.9 per cent of the male workers. Serum vitamin B12 and folic acid levels were normal for female workers. The adequate serum levels of vitamin B12 and folic acid might be the result of the habit of the workers to consume tonic drinks which contain glucose, caffeine, and vitamins especially vitamins B6, and B12.
