The role of science in guiding interventions and programs and contributing to progress in achieving global targets is undeniable. In public health nutrition, biological research in the past century focused largely on single nutrients and provided the basis for addressing nutritional deficiencies. This focus has now expanded to consider evidence including, but not limited, to knowledge about food, diet, behavior, context, and culture. The complex double burden of malnutrition will need to be addressed through a wider lens that appreciates the multiple and interrelated facets that underpin it.
Despite the acknowledged importance of translational research in improving nutritional outcomes, significant gaps remain in the process leading from science to practice. This article sheds light on 2 examples that demonstrate this, namely, anemia and stunting. Further, much work is still required to translate the current evidence base into effective actions that result in impact at scale, pointing toward the need for more implementation research in nutrition. Key Messages: While discoveries may take time to surface and implementers are impatient to address the challenge at hand, it is essential to identify and deploy the best available evidence while continuously advancing the evidence base, and to seek the right balance between action and inaction.
科学在指导干预措施和项目并为实现全球目标方面的进展做出贡献的作用是不可否认的。在公共卫生营养领域,过去一个世纪的生物学研究主要集中在单一营养素上,为解决营养不足问题提供了基础。现在,这一重点已经扩大到考虑证据,包括但不限于关于食物、饮食、行为、背景和文化的知识。需要通过更广泛的视角来解决复杂的双重营养负担问题,以理解支撑它的多种和相互关联的方面。
尽管人们认识到转化研究对于改善营养结果的重要性,但从科学到实践的过程中仍然存在重大差距。本文通过两个例子来说明这一点,即贫血和发育迟缓。此外,还需要大量工作将当前的证据基础转化为有效行动,从而在大规模上产生影响,这表明营养领域需要更多的实施研究。
虽然发现可能需要时间才能显现出来,实施者也急于解决当前面临的挑战,但在不断推进证据基础的同时,确定和利用现有最佳证据至关重要,并且需要在行动和不作为之间寻求适当的平衡。
