[Assessment of energy and macronutrients supply in daily food rations of people exposed to hand transmitted vibrations].
BACKGROUND
Occupational exposure of workers to mechanical hand transmitted vibrations may result in the development of nonspecific lesions. Balanced diet is one of factors that protect human organism against abnormalities resulting from occupational exposure. The aim of this study was to assess the supply of energy and macronutrients in daily food rations (DFR) of people exposed to hand transmitted vibration.


METHODS
Eighty workers, including 37 men (mean age 44.6 years) and 43 women (mean age 44 years) exposed to hand transmitted vibrations were recruited in this study. Of those, 72 people worked in crystal glassworks as glass cutters, 5 people were physiotherapists and 3 were woodcutters. For all workers, there was measured exposure to hand transmitted vibration. Nutritional status was assessed using 24-hour dietary recall; the procedure was repeated 3 times. The results of the nutritional assessment were compared with recommended daily allowances (RDA) for energy, protein, minerals and vitamins, total carbohydrates, total fat, saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), cholesterol and dietary fibre.


RESULTS
The average intake of energy in daily food rations of the women was too low while men received the appropriate amount of energy. Average protein intake by men and women was higher than the relevant RDA. The average amount of carbohydrates received by the surveyed women and men were too low, just as the consumption of PUFA, dietary fibre, potassium and calcium. We also found an excessive, average supply of total fat, MUFA, SFA, cholesterol and most of the vitamins with the DFR of the women and men.


CONCLUSIONS
The nutrition in the group of workers exposed to hand transmitted vibration was found to be imbalanced due to excessive intakes of total fat, saturated fatty acids and cholesterol combined with insufficient consumption of carbohydrates, dietary fibres, potassium and calcium. The co-occurrence of vibration and imbalanced diet may increase the susceptibility of the subjects to cardiovascular and bone diseases.
