Energy and macronutrient intakes of employees at different levels of work intensity in China from 2010 to 2012

Abstract

To analyze the intake of energy and macronutrients of employees at different levels of work intensity in China. Based on the data of National Nutrition and Health Survey in 2010-2012, this paper analyzed the energy and macro nutrients intakes of employees at three levels of working strength. The energy intake of employees in China was 1952. 7 kcal/d, the intakes of protein, fat and carbohydrate were 62. 7 g/d, 76. 6 g/d and 254. 0 g/d, respectively, the energy supply ratios were 13. 1%, 34. 9% and 52. 4%, respectively. From food sources of energy, the percentage of total energy provided by cereals and animal foods was 47. 7% and 18. 2%, respectively. The percentage of protein from cereal, legumes and Animal food was 39. 8%, 6. 7% and 37. 5%, respectively. The percentage of fat from animal food was 34. 8%. From the age and work intensity groups, the energy intake was lower in the low age group and the light work intensity of employees. There was the lowest intake of protein and fats in high age groups with heavy work intensity. Energy levels form protein and fat were highest in the light intensity group. Energy supply from cereal food was the highest in the group with heavy work intensity and energy supply from animal food was the highest in the group with low age group and light work intensity. The intake of high quality protein and animal food fat decreased with the increase of age and work intensity. The energy intake of employees in China is lower than the recommended energy intake for Chinese residents, and fat provides a higher proportion of energy. Employees with high age and heavy work intensity have insufficient protein intake, and the unreasonable dietary structure was particularly prominent with them, and their nutritional status needs to be paid more attention.
