目的分析中国65岁及以上老年居民蛋类食物的摄入状况。方法数据来自2010—2012年中国居民营养与健康状况监测项目中膳食频率法问卷调查。采用多阶段分层与人口成比例的整群随机抽样方法进行抽样,研究对象为中国内地31个省份150个监测点65岁及以上老年居民,共8205名,计算其蛋类食物的摄入量、消费率及达到中国膳食指南推荐量的人群比例。结果 2010—2012年中国65岁及以上老年居民蛋类摄入量为25.7 g/d(P25 9.2 g/d,P50 25.7 g/d,P75 50.4 g/d),大城市、中小城市、普通农村、贫困农村分别为36.9~50.0、21.4~28.6、14.3~21.4和17.1~21.4 g/d。蛋类食物消费率为93.5%,大城市、中小城市、普通农村、贫困农村分别为93.0%~96.8%、87.6%~95.2%、91.5%~96.0%和85.5%~94.9%。65岁及以上居民蛋类摄入量达到我国膳食指南推荐量人群比例为35.5%,大城市、中小城市、普通农村、贫困农村的人群比例分别为49.1%~58.7%、29.4%~37.9%、18.5%~31.0%和26.4%~31.3%。结论中国65岁及以上居民蛋类食物消费率较高,但摄入量不足,与中国居民膳食指南中蛋类食物推荐量仍有很大差距。

Objective To analyze the consumption of eggs in Chinese aged 65 years and above. Methods Data were collected from 2010- 2012 China National Nutrition and Health Surveillance. Information on consumption was collected by using the FFQ. The participants selected were 65 years old and above on 150 counties from 31 provinces in China by using the method of multi-stage stratified cluster randomization sampling. The average consumption of eggs was reported by quartile. Results The average daily consumptions of eggs in Chinese aged 65 and above residents were 25. 7 g( P25 9. 2 g / d,P50 25. 7 g / d,P75 50. 4 g / d). In the big city,small and medium-sized city,rural and poor rural areas,those were 36. 9- 50. 0 g / d,21. 4-28. 6 g / d,14. 3- 21. 4 g / d and 17. 1-21. 4 g / d,respectively. Percentage of these residents on intake of eggs were 93. 5%. In the big city,small and medium-sized city,rural and poor rural,those were 93. 0%-96. 8%,87. 6%-95. 2%,91. 5%-96. 0% and 85. 5%-94. 9%, respectively. The proportion of people whose total amount of eggs intake reached 40 g / d was 35. 5%. Insuch mentioned areas,those were 49. 1%-58. 7%,29. 4%-37. 9%,18. 5%-31. 0% and26. 4%-31. 3%,respectively. Conclusion The consumption rates of eggs were quite high in Chinese aged 65 years and above,whereas the intake of eggs was inadequate. Compared with recommendation of The Dietary Guidelines for Chinese Residents,there was still a large gap.
