What percentage of Ideal Body Weight (IBW) corresponds to Grade 0 (normal) for acute malnutrition?

In the context of assessing acute malnutrition, the World Health Organization (WHO) defines normal nutrition status as a percentage of Ideal Body Weight (IBW). Specifically, a grade of 0, which signifies a normal nutritional state, is associated with individuals who have an IBW of 90% or above. This threshold indicates that the individual is within an acceptable weight range for their height, reflecting adequate nutritional status.

Understanding these classifications is essential in pediatrics for the recognition and management of malnutrition in children. The rates below this threshold reflect increasing severity of malnutrition as follows: those in the 80%-89% range would still be considered at risk but not severely malnourished, while those in the 70%-79% range are classified as having moderate acute malnutrition. Weighing less than 70% of their IBW indicates severe acute malnutrition. Hence, the correct option effectively delineates the cutoff for what is deemed a normal nutritional status in young patients.
