2010～2012年中国60岁及以上老年居民膳食钙摄入状况分析

DIETARY CALCIUM INTAKE AMONG CHINESE ELDERLY DURING 2010-2012

目的了解2010~2012年中国60岁及以上老年居民膳食钙的摄入状况。方法采用2010~2012年中国居民营养与健康状况监测中60岁及以上老年人的膳食调查资料,计算与分析比较不同地区、不同性别、不同年龄老年人群膳食钙的摄入量和来源现状。结果中国60岁及以上老年人膳食钙摄入量为344.20 mg/d,达到或超过RNI水平的仅占1.19%,城市老年人膳食钙摄入量显著高于农村,60~69岁的老年人膳食钙摄入量显著高于70岁以上的老年人。膳食钙的主要来源为蔬菜和粮谷类食物,蔬菜所占比例约为33%,粮谷类约为22%,奶类来源所占比例则不足7%;且与2002年相比,2010~2012年中国60岁及以上老年人膳食钙摄入量明显下降,下降幅度为0.4%~22.8%。结论中国60岁及以上老年居民膳食钙摄入严重不足。

Objective To investigate the status of dietary calcium intake among Chinese elderly over 60 years old during 2010 to 2012.

The dietary calcium intake was significantly higher in the urban elderly than in the rural elderly. The dietary calcium intake was significantly higher in the elderly aged 60-69y than in the elderly over 70y. The main food source of dietary calcium was vegetables （33%） and cereals （22%）. The proportion of calcium from the milk was lower than 7%. Compared with the calcium intake in 2002, the dietary calcium intake of the elderly decreased by 0.4%-22.8% during 2010 to 2012. Conclusion The intake of dietary calcium is seriously inadequate in the Chinese elderly over 60y.
