Abstract

The objectives of this study were to assess the nutritional status, daily energy intake, and daily energy expenditure of coal miners in Turkey. A total of 135 healthy coal miners (aged 19-64 years) were evaluated. Heart rates were measured using Polar watches, and the total energy expenditure was calculated using physical activity level formula and Hiilloskorpi equation. The average body mass index of the participants was 25.7 ± 3.98 kg/m2, and the average energy intake was 3,973.7 ± 420.85 kcal. According to Dietary Reference Intakes, the energy and nutrient intakes of the miners were adequate, except for the intake of vitamin D. The coal miners were found to be at moderate (43.0%), heavy (41.5%), and very heavy (13.3%) activity levels. Calculations of the energy expenditure at work were found to be 2,189.8 ± 376.19 to 2,788.8 ± 359.89 kcal per day. Further studies have to be conducted for developing national standards for each occupation.
