This indicator measures the proportion of children under five who are classified as underweight, specifically those falling below three standard deviations (-3 SD) from the median of the WHO Child Growth Standards. It reflects a critical aspect of child health, highlighting severe malnutrition levels that pose significant health risks and developmental challenges. By focusing on the extreme end of the underweight spectrum, this metric not only underscores the urgency of nutritional interventions but also informs policymakers and health practitioners about the severity of childhood malnutrition in a given region. Tracking this indicator can aid in evaluating the effectiveness of targeted nutrition programs and overall public health initiatives aimed at reducing child malnutrition and improving long-term health outcomes.
