[Intakes of energy and macronutrient among the elderly in nine provinces( autonomous region), China during 1991-2015].

To analysis the status and trend of energy and macronutrient intake among elderly aged 60 and older years old in nine provinces( autonomous region) of China.The data of China Health and Nutrition Survey from 1991 to 2015 were used, which elderly ≥60 years old were selected as the subjects. The 3-consecutive day 24-hour dietary recall was used to collect information on food intake, the condiment intake was collected by weighting and bookkeeping method. Food consumption was converted into energy and various nutrient intakes by food composition table.The intakes of energy was 1706. 8 kcal/d, protein, fat and carbohydrates was 52. 2 g/d, 61. 4 g/d and 219. 3 g/d respectively in 2015. The percentage of energy from protein, fat and carbohydrates was 12. 3%, 33. 3% and 53. 0%respectively. Compared with 1991, the intake of energy, protein, carbohydrate decreased352. 3 kcal/d, 11. 5 g/d and 89. 8 g/d respectively. The percentage of energy from fat increased 9. 0 percentage points, carbohydrates decreased 8. 7 percentage points and protein was not changing. In 2015, the intakes of protein and carbohydrates had urbanrural differences. The elderly at the high income level had high intakes of protein and fat, the carbohydrates intake at low level. The main source of energy, protein and fat is grain, other food and edible oil respectively.The elderly of Chinese nine provinces( autonomous region) need to increase energy consumption, reduce the fat intake. We should guide rural and low-income elderly people to choose more economical and accessible food to meet their nutritional needs through food substitution. Focus on changes in blood lipids that may result from excessive intake of animal food in urban and high-income elderly people.
