Abstract

Introduction: Child undernutrition is becoming a physical and mental health problem worldwide as well as an economic development one. It is characterized by wasting (low body mass for stretch stature), stunting (low stretch stature for age) or being underweight (low body mass for age), and reflects nutritional deficiencies in growth and development at critical stages of life. In accordance with the United Nations initiative to reduce malnutrition by 2030, diagnosis, treatment or prevention of any type of child malnutrition is necessary. The objective of this review and consensus document is to offer a standardized frame of measurements and adaptations to the protocol used by the International Society for the Advancement of Kinanthropometry (ISAK) to evaluate undernourished children. Methods: A systematic literature review was conducted using the PRISMA guidelines to identify the existence of different anthropometric measurements and methods to evaluate undernourished children. There are important differences in severe acute or chronic child malnutrition clinical conditions which require a different anthropometric approach. Additionally, the distinct growth and development stages of a lifespan require the adaptation of materials and methods used. Other ethical and practical recommendations are included as necessary in the evaluation of undernourished children. Results: Finally, estimation of body composition in this population must be approached with caution since clinical conditions do not always allow for the necessary measurements. Conclusion: This review can serve as a practical clinical guideline to conduct anthropometric measurements in child undernutrition.
