Abstract:
Objective:To investigate the average dietary nutrients intake status among Chinese residents between 2010-2012, and to compare the difference between rural and urban areas.
Methods:Data were collected from Chinese Nutrition and Health Surveillance between 2010-2012. Based on regional features and economic development levels, China's county-level divisions were classified into four types: big city, medium and small city, ordinary rural area and poor rural area. A total of 62 857 valid subjects, including 14 017, 16 539, 19 910 and 12 391 respondents in each group separately, were enrolled by Multi-stage stratified proportion to the population cluster random sampling method. The dietary survey was conducted by recalling the 24 h diet in 3 consecutive days and weighting condiment. The daily dietary intake of energy, macronutrient, dietary fiber, vitamin, and mineral substance per resident were calculated based on China Food Composition.
Results:The average energy intake per resident in Mainland China was 9 047.1 kJ, with highest (9 719.3 kJ) in poor rural area and lowest (8 490.4 kJ) in medium and small city. The average dietary protein intake was 64.2 g, with highest (73.9 g) in big city and lowest (60.7 g) in poor rural area. The average dietary fat intake was 79.7 g, with highest (89.4 g) in big city and lowest (70.6 g) in poor rural area. The average intake of micronutrients of vitamin A, vitamin B2, vitamin C, calcium, iron, phosphorus, zinc was separately 441.9 μg, 0.8 mg, 80.1 mg, 364.3 mg, and 21.4 mg; which were lower than Chinese Dietary Reference Intakes. The percentage of population whose average intake of vitamin A, vitamin B2, vitamin C, calcium were lower than estimated average requirement was separately 77.0%, 90.2%, 67.7%, and 96.6%.
Conclusion:The supply of 3 macronutrient was sufficient in mainland China. However, it was a common issue that there was excessive intake of fat but deficient intake of micronutrients such as vitamin, calcium, iron and zinc. There were differences in nutrition intake among big city, medium and small city, ordinary rural area and poor rural area.
