Abstract

The purpose of this study was to assess the nutritional status of Korean workers with occupational exposure to lead by estimating nutrients and flood intakes so that we can eventually establish the dietary guidelines to be recommended for the lead workers. Food consumption survey was conducted by a 24-hr recall method with 135 lead workers and 50 non-exposed controls. Food intake data were convened into nutrients intake using computer aided nutritional analysis program. Mean daily energy intake and percentage of recommended daily allowance (RDA) of male lead workers were 2138 local and 87% of RDA while those of control were estimated as 2234 kcal and 91% of RDA. Mean daily intakes of nutrients of male lead workers were 78 g (111% RDA) for protein 502 mg (71% RDA) for calcium, 11.7 mg (97% RDA) for iron, 665 $\mu$g R.E (95% RDA) for vitamin A, 1.39 mg (108% RDA) for thiamin, 1.14 mg (77% RDA) for riboflavin, 15 mg N.E (92% RDA) for niacin and 66 mg (94% RDA) for vitamin C. On average, male lead workers showed significantly lower protein, calcium, iron, sodium, potassium, niacin and vitamin C intakes than control group while cholesterol intake of the male lead workers was significantly higher than that of control group. Intakes of calcium of male lead workers were Less than 75% RDA meaning that nutritional intake of calcium of male lead workers was insufficient and could possibly result in nutritional deficient. Some food groups such as milk, meat and fish must be strongly suggested to improve nutritional status of lead workers. Continuing nutrition monitoring and appropriate nutrition intervention for lead workers most be conducted further.
