迈向更加健康的未来:原子能机构营养不良双重负担专题讨论会闭幕

全世界三分之一的人口患有某种形式的营养不良,如肥胖、营养不足或营养缺乏,而且在许多病例中,人们患有不止一种形式的这种疾病。

全世界三分之一的人口患有某种形式的营养不良,如肥胖、营养不足或营养缺乏,而且在许多病例中,人们所患有不止一种形式的这种疾病。上周参加了解营养不良双重负担促进有效干预问题国际专题讨论会的专家得出结论认为,这一复杂问题的长期、可持续的解决方案需要更好的关于营养和行动影响的数据,增加有针对性的投入以及跨政府、商业、研究人员和公众的更加综合性的方案。核相关技术能够准确地评定各种形式的营养不良,并为加强注重行动的解决方案提供数据。

“粮食危机是我们现在仅次于气候变化的最大的人道主义危机,”奥地利联邦就业、社会福利、卫生和消费者保护部卫生特使Clemens Auer说。“联合国将此问题列入‘可持续发展目标’太好了,但决策者还必须了解区块化、商业因素和利益,并处理行业问题,如食品和饮料业。”

世界上每个国家都至少受到一种形式的营养不良的影响,有四分之一的国家正面临营养不良“双重负担”。这种“双重负担”系指在国家和社区中粮食不安全、微量营养素缺乏、营养不足和传染性疾病与超重、肥胖和相关非传染性疾病共存的复杂情况,这种情况甚至能够在个体人身上共存。

截止2017年,1.51亿五岁以下儿童发育迟缓(22.2%),5100万患有严重营养不良(7.5%)和3800万超重(5.6%)。

“各种形式的营养不良是迄今过早死亡和残疾的最大致因。全球正在总体上进行改进,但十分缓慢,”新西兰奥克兰大学人口营养和全球健康教授Boyd Swinburn说。

450多名科学家、卫生和营养学专业人员、决策者以及国际组织、非政府组织和公民社会的代表共同参加了这次为期四天的专题讨论会。这是第一次原子能机构、世界卫生组织(世卫组织)和联合国儿童基金会(儿童基金会)协力主办关于解决营养不良双重负担的大型会议。

    专题讨论会上的讨论、专题介绍和大字报展示活动从五个角度全面和深入地考虑遏制营养不良问题:流行病学、生物学、评定、干预和政策影响。他们还探讨了联合国营养问题行动十年等国际组织和全球努力所起的作用,以及加强跨组织、国家和社区的集体行动对加强抗击营养不良问题的重要性。

    “过去五年中,集体领导力得到加强,现在到了将其提高到一个新的水平的时候,”全球营养改善联盟执行主任和世界粮食奖获得者Lawrence Haddad说。他说明了原子能机构、儿童基金会和世卫组织等联合国组织如何与各国合作,为支持国家战略和“增强营养”运动这一改善营养的全球集体倡议设定并实现目标。

    “培养下一代,并走出去,告知人们科学论文意味着什么,以及他们可以做什么才能对其采取行动,”Haddad说。“我们必须振奋精神,联合在一起,但比这更重要的是,我们必须为我们的事业征募新兵。”

    目标和今后的集体行动是贯穿专题讨论会的一个共同主线。专题介绍和分组会议为与会者提供机会确定具体的行动、了解新的评定工具和讨论战略机遇与行动,以及规划如何估量营养不良和评定采用稳定同位素等工具的干预措施的影响。

    “稳定同位素技术能够帮助评价和监测已实施的营养计划。我们能够设计和实施一系列广泛的干预措施。但是,如果我们没有一种可靠方法对这些措施进行评价,我们如何知道它们在起作用呢?”原子能机构人体健康处处长马伊・阿卜杜勒-瓦哈卜说。“原子能机构通过加强在成员国利用稳定同位素技术处理很多形式的营养不良问题。这是解决此难题的一个重要组成部分,并且还能够有助于支持其他的计划和倡议,如世卫组织和儿童基金会的实地计划。

    在专题讨论会结束时,与会者提出了未来前行方向的行动,反映了这一周期间确定的成果和结论。这些行动包括:

    • 建立跨学科和各级利益相关方的伙伴关系;
    • 向公众和其他非营养行业阐明营养问题;
    • 与青少年进行交流,促进提高认识。

    新的营养学资源启用:原子能机构数据库和《2018年全球营养报告》

    在会议期间,原子能机构启用了关于过去三十年能量消耗测量的新数据库。数据是利用称作双标记水法的一种稳定同位素技术收集的。这些数据将有助于研究人员研究日益流行的久坐生活方式对饮食需求的影响,并支持各国制定更好的健康政策以遏制世界范围内不断增加的肥胖流行病。更多地了解原子能机构新数据库

    该数据库得到了《2018年全球营养报告》的补充,该报告系世界范围内开展的包括上周会议在内的19次活动所发起的。该报告是国际粮食政策研究所编写的关于世界范围内营养不良状况的数据主导的出版物。它提供全球、地区和国别营养评定,以及为作出改进正在进行的努力。它还跟踪了解全球营养目标方面的进展,并概述加快这种进展的步骤。原子能机构是支持编制该出版物的利益相关方团体的一分子。

    在这次会议之前,还发起了一次视频短片竞赛活动,以提高对公众营养不良的认识,并鼓励以回答下述问题的方式进行参与:“如果你有机会,你将如何利用基于科学的方案处理营养不良双重负担问题?”获奖短片在专题讨论会闭幕会议期间进行了播放,系由来自墨西哥蒙特雷大学的学生Daniela Garza、Lorena Lee和Viviana Torres创作。作为很多形式营养不良共存的一个实例,他们突出了对墨西哥青少年女孩中肥胖和贫血问题的研究情况。该短片建议作出跨学科的统一科学努力,并制定更强有力的处理营养不良问题公共政策。

    Symposium discussions, presentations and poster sessions involved a comprehensive and in-depth look at combatting malnutrition from five angles: epidemiology, biology, assessment, interventions and policy implications. They also explored the role of international organizations and global efforts, such as the United Nations Decade of Action on Nutrition, and the importance of strengthening collective actions across organizations, countries and communities to ramp up the fight against malnutrition.

    “Collective leadership has improved in the past five years and now is the time to take it to the next level,” said Lawrence Haddad, Executive Director at Global Alliance for Improved Nutrition (GAIN) and 2018 World Food Prize laureate. He explained how UN organizations, such as the IAEA, UNICEF and the WHO, can work with countries to set out and achieve targets to support national strategies and the Scaling Up Nutrition movement, a global collaborative initiative to improve nutrition.

    “Build the next generation and get out there and tell people what the scientific papers mean and what they can do to act on them,” Haddad said. “We have to elevate and come together, but more than that, we have to recruit recruits to our cause.”

    Targets and collective actions for the future were a common thread throughout the symposium. Presentations and breakout sessions provided opportunities for participants to identify concrete actions, learn about new assessment tools and discuss strategic opportunities and actions, as well as chart out how to measure malnutrition and assess the impact of interventions with tools such as stable isotopes.

    “Stable isotope techniques can help evaluate and monitor nutrition programmes that are in place. We can design and implement a wide range of interventions. However, if we don’t have a dependable method to evaluate them, how can we know if they are working?” said May Abdel-Wahab, Director of the IAEA’s Division on Human Health. “The IAEA tackles many forms of malnutrition through strengthening the use of the stable isotope techniques within Member States. It’s an important piece of the puzzle and can also help support other programmes and initiatives, such as WHO and UNICEF programmes on-the-ground.”

    In closing the symposium, participants laid out actions on the way forward, reflecting the findings and conclusions identified over the course of the week. These included:

    • Building partnerships across disciplines and stakeholder levels;
    • Demystifying nutrition for the public and other non-nutrition sectors; and
    • Engaging with youth to boost awareness raising.

    Launch of new nutrition resources: IAEA database and 2018 Global Nutrition Report

    On the margins of the conference, the IAEA launched a new database on energy expenditure measurements from the last three decades. The data was collected using a stable isotope technique called the Doubly Labelled Water method. This data will help researchers look at the impact of growing sedentary lifestyles on dietary needs and support countries in devising better health policies to combat the growing obesity epidemic worldwide. Read more about the new IAEA database.

    Complementing the database is the 2018 Global Nutrition Report, which was launched at four events worldwide including the conference last week. The independent report is a data-driven publication on the status of malnutrition around the world produced by experts across the nutrition comunity. It provides global, regional and country-by-country assessments of nutrition and the efforts being made to improve it. It also tracks progress on global nutrition targets and outlines steps for speeding up that progress. The IAEA is part of the stakeholder group that provides the overall strategic direction for the report.

    In the lead up to the conference, a video competition was also launched to raise awareness about malnutrition with the public and encourage engagement by answering the question: “If you had a chance, how would you tackle the double burden of malnutrition using a science-based approach?” The winning short video, which was shown during the symposium's closing session, was created by Daniela Garza, Lorena Lee and Viviana Torres, students from the University of Monterey in Mexico. They highlighted their research on obesity and anemia in teenager girls in Mexico as an example of the co-existence of many forms of malnutrition. The video proposed unifying scientific efforts across disciplines and creating stronger public policies to tackle malnutrition. Learn more about the competition and watch the winning video.
