Calibration should be considered when body fat percentage is measured by BIA.

There are fixed bias and proportion bias between BIA and DXA in measuring total body fat percentage and trunk fat percentage in Chinese men and women. Calibration should be considered when body fat percentage is measured by BIA.

To understand the dietary diversity and food sources of different groups in Arun Banner. Comparing and analyzing the changes of dietary diversity of local residents in different periods.

In October 2019, according to the differences of Kashin-Beck disease conditions and land use patterns of Arun Banner, Hulun Buir, 78 rural residents were randomly selected from four villages to investigate the frequency of daily food consumption by using self-made food frequency questionnaire. Dietary diversity score(DDS) was used to evaluate the dietary diversity of different populations.

The average DDS of the investigated residents was 9. 76±2. 32. DDS of the residents of Minzu and Tieshan villages(10. 14±2. 66) in the West was higher than that of Longtoushan and Hongqi villages(9. 42±1. 95) in the East. However, the difference was not statistically significant(Z=-1. 875, P& gt; 0. 05). DDS in males(10. 37±2. 47) was significantly higher than that in females(9. 36±2. 14)(P& lt; 0. 05). There was no significanes to be stable and gradually controlled.

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 wi and the unreasonable dietary structure was particularly prominent with them, and their nutritional status needs to be paid more attention.

To analyze the intake and structure of energy and macronutrients of farmers under three kinds of job types working, farming and housework in China, and analyzes the intake status under different work intensity.

Based on the data of China Nutrition and Health Survey in 2010-2012, this paper analyzed the dietary intake of farmers over 18 years old at three job types and different work intensities.

The energy intake of farmers in China was 2149. 5 kcal/d, and that of men and women were 2345. 2 kcal/d and 1985. 4 kcal/d, respectively. Farming farmers took in the highest energy and the domestic farmers took in the lowest energy. The average protein intake of farmers was 60. 8 g, 66. 0 g for men and 56. 4 g for women. The protein intake of working, farming and housework farmers, showed a downward trend. The fat intake of farmers was 66. 6 g, including 71. 9 g for men and 62. 1 g for women. With the three main forms of working, farming and housework, the fat intake showed a downward trend. The carbohydrate intake is insufficient, especially the heavy work intensity. The nutrition needs of the population should get more attention.

To analysis the fresh vegetables and fresh fruit consumption among the elders aged 60 and above of China in 2015.

The consumption of fresh vegetables and fresh fruits in the past 12 months was calculated by using the food frequency questionnaire data of 58 335 elderly people aged 60 and above from “China National Chronic Diseases and Nutrition Surveillance of Adults(2015)”, and the intake status was evaluated according to the recommended intake of Dietary Guidelines for Chinese Residents(2016).

The consumption rate of fresh vegetables among the elderly in China was 98. 7%, the median intake of the whole population was 270. 0 g, the median intake of the consumer population was 300. 0 g, and the proportion of under-intake was 49. 6%. The fresh fruit consumption rate was 84. 2%, the median intake of the whole population was 30. 0 g, and the median intake of the consumer population was 50. 0 g. The proportion of insufficient intake of fresh fruits reached 85. 2%. The frequency of intake of fresh vegetables was mainly 2 times/day, accounting for 45. 9%; fresh vegetables intake 1-3 times/week and ≥2 times/day were 38. 7% and 35. 6%, respectively. The consumption rate and intake of fresh vegetables and fruits were both higher in urban areas than in rural areas, and decrease significantly with increasing age, lower educational background and lower income. click here In addition, the consumption rate and intake were lower in elderly living alone.

China& apos; s elderly people aged 60 and above have insufficient intake of vegetables and fruits. Health education and dietary guidance should be carried out, and intervention measures should be taken for key populations to effectively promote a reasonable diet for the elderly.

To survey the intakes of energy and macronutrients in 6-11 years old age group in 2016-2017 in China.

Multi-stage cluster randomization sampling method was used to collect the data from China Nutrition and Health Surveillance of Children and Lactating Mothers in 2016-2017 in 257 surveillance sites of 31 provinces. 24-h dietary recalls for three consecutive days were used to obtain the dietary information. The intakes of energy, protein, fat and carbohydrate were calculated by the China Food Composition, and the intakes of protein were assessing by Chinese Dietary Reference Intakes(DRIs).

A total of 8777 children in 6-11(9. 2±1. 6) years old group were recruited in this surveillance, the number of boys and girls were 4364 and 4413, respectively. The general intakes of energy were 1591. 7 kcal and that of boys and girls were 1624. 1 kcal and 1559. 7 kcal, respectively. The energy intakes in urban children were higher than rural children. The energy intakes in the east region were the highest and the middle region were the lowest.
