Status of dietary energy and macronutrients intake among Chinese older adults from 2010 to 2012

OBJECTIVE: To analyze dietary energy and macronutrients intake among Chinese older adults from 2010 to 2012. METHODS: Data was from Chinese Nutrition and Health Surveillance in 2010-2012. Dietary intake information was collected by three days food recall and weighed record of edible oil and condiments among 16 612 older adults. Daily energy and three macronutrients intake were calculated according to Chinese Food Composition 2004 and 2009 edition, and then evaluated by 2013 Chinese dietary reference intake. RESULTS: The daily average energy, carbohydrate, protein and fat intake of Chinese older adults was(1840. 9 ± 636. 7) kcal/d, (255. 9 ± 106. 8) g/d, (55. 6±22. 7) g/d and(66. 8±35. 0) g/d, respectively. The mean proportion of energy supplied from carbohydrate, protein and fat was(55. 7% ± 12. 1%), (12. 3% ± 3. 4%)and(32. 5% ± 11. 7%), respectively. Total energy intake, carbohydrate intake and proportion of energy from carbohydrate among urban elderly were lower than that in rural, whereas protein and fat intake as well as their contribute rate for energy were higher in urban than those in rural. Regardless of urban and rural areas, four regions and genders, there was a decreasing trend of energy and macronutrient intake with the increase of age(P<0. 01). There 57. 0% of male and 53. 8% of female had lower protein intake than the recommended value, while 56. 7% of male and 56. 8% of female had higher fat contribution for energy upper than 30%. The rate of protein intake deficiency among participants aged 60-69 years old, 70-79 years old, 80 years old and above was 51. 0%, 61. 2% and 68. 6% respectively, and the proportion of energy from fat that exceeded 30%was 56. 9%, 56. 3% and 57. 1%, respectively. CONCLUSION: The daily average macronutrients intake model was unreasonable with higher fat but lower protein among Chinese older adults.
