Abstract

Night shift work resulted in a reduction in food and coffee intake during work hours.

No changes in energy, nutrient intake, or coffee/tea consumption were found between 8-hour morning and afternoon shifts.
Night shift workers showed a redistribution of food and coffee intake without an overall reduction in 24-hour consumption.
Energy intake and food quality remained stable across shifts, with the exception of lower carbohydrate intake for day- and three-shift workers during days off.
Alcohol consumption increased for all groups during days off.

To study the impact of work hours on eating habits the dietary intake of 96 male industrial workers on day work and two- and three-shift work was investigated using repeated 24 h recall. The intake of energy, 14 nutrients, and coffee and tea was computed, using a nutrient data base, for 8 h work and shifts (day, morning, afternoon, night) and for the 24-h periods including these work shifts. No changes in intake of energy, nutrients and coffee/tea were observed between 8 h morning and afternoon shifts, but there was a reduction in intake during 8 h night shifts. Night shift work caused a redistribution of food and coffee intake, but not an overall 24 h reduction. On the whole, the energy-intake and the quality of food intake (percentages of energy from macronutrients and density of micronutrients) were not affected by shift work, although the intake of carbohydrates was lower in day- and three-shift workers during days off. The intake of alcohol was higher during days off in all groups. In summary, two- and three-shift work in this study affected the circadian distribution of food intakes and coffee consumption, but not the overall 24-h consumption.
