Intakes of energy and macronutrients in 6-11 years old age group in 2016-2017 in China

Abstract

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. The general protein intakes were 50. 0 g, and that of boys and girls were 50. 9 g and 49. 1 g, respectively. The intakes of protein in urban children were higher than in rural. The intakes of protein in east region were higher than that in the middle and west regions. The ratios that above RNI of protein intakes were 52. 4%, and the ratios of urban and rural were 63. 0% and 42. 9%, respectively. The general fat intakes were 69. 6 g and that of boys and girls were 71.4 g and 67.8 g, respectively. The fat intakes in urban children were higher than in rural, but in the rural of the west the fat intakes were higher than in the urban of the east. The general intakes of carbohydrate were 196. 3 g, and that of boys and girls were 199. 5 g and 193. 2 g, respectively. The carbohydrate intakes in urban children were higher than in rural, and in the west region the intakes of carbohydrate were higher than in the east region. But in the rural populations, the carbohydrate intakes in the west region were higher than that in the east region. Comparing with 2010-2013, obvious changes of energy and macronutrients intakes in China 6-11 y children were observed in 2016-2017 surveillance. Inadequate intakes of protein were still the problem in rural children populations. The increase of fat intake was larger and more significant in the western region.
