Position Statement on Malnutrition

To tackle malnutrition, we need a systemic approach. Understanding of the whole spectrum of malnutrition across all age groups and life stages is key to effective action. The first and basic step is across-the-board adoption of the up to date definition of the problem and thorough understanding of its current local, national and global extent.

Malnutrition refers to deficiencies, excesses, or imbalances in a person’s intake of energy and/or nutrients. The term malnutrition addresses 3 broad groups of conditions:

• undernutrition, which includes wasting (low weight-for-height), stunting (low height-for-age) and underweight (low weight-for-age)
• micronutrient-related malnutrition, which includes micronutrient deficiencies (a lack of important vitamins and minerals) or micronutrient excess
• overweight, obesity and diet-related noncommunicable diseases (such as heart disease, stroke, diabetes and some cancers)
