全球有8亿多人营养不良，120亿人患有一种或多种慢性微量营养素缺乏症。全球6%以上的死亡率和发病率负担与营养不良和精神疾病有关。本文显示，2011年，由于膳食供应不足，分别有35亿人和11亿人面临钙（Ca）和锌（Zn）缺乏的风险。2011年全球平均日粮钙和锌供给量分别为684±211和16±3 mg人均- 1 d - 1（±SD）。1992年至2011年间，全球钙和锌缺乏症的风险分别从76%和22%下降到51%和16%。2011年，大约90%的钙和锌缺乏症风险人群在非洲和亚洲。据我们所知，这是基于食物供应对膳食钙缺乏风险的首次全球估计。我们的结论是，通过饮食多样化和粮食和农业干预措施（包括强化、作物育种和使用微量营养素肥料）继续降低钙和锌缺乏症风险仍将是一项重大挑战。
Globally, more than 800 million people are undernourished while >2 billion people have one or more chronic micronutrient deficiencies (MNDs). More than 6% of global mortality and morbidity burdens are associated with undernourishment and MNDs. Here we show that, in 2011, 3.5 and 1.1 billion people were at risk of calcium (Ca) and zinc (Zn) deficiency respectively due to inadequate dietary supply. The global mean dietary supply of Ca and Zn in 2011 was 684 ± 211 and 16 ± 3 mg capita−1 d−1 (±SD) respectively. Between 1992 and 2011, global risk of deficiency of Ca and Zn decreased from 76 to 51%, and 22 to 16%, respectively. Approximately 90% of those at risk of Ca and Zn deficiency in 2011 were in Africa and Asia. To our knowledge, these are the first global estimates of dietary Ca deficiency risks based on food supply. We conclude that continuing to reduce Ca and Zn deficiency risks through dietary diversification and food and agricultural interventions including fortification, crop breeding and use of micronutrient fertilisers will remain a significant challenge.
