Which of the following indices is less commonly used to assess the anthropometric status of children aged 0-5 years?

Head circumference-for-age is less commonly used to assess the anthropometric status of children aged 0-5 years primarily because it focuses on brain growth and development rather than overall nutritional status or growth patterns related to height and weight. While head circumference is an important measurement for assessing neurological development and can indicate conditions such as malnutrition or developmental delays, it does not provide a comprehensive overview of a child's nutritional status.

In contrast, height-for-age, weight-for-height, and weight-for-age are more frequently employed indices that offer insights into different aspects of growth—stunting, wasting, and underweight, respectively. These measurements help health professionals assess the growth trajectory of children and are essential for determining appropriate interventions and resources to support healthy development.

Ultimately, the practical application and relevance of these other indices make them more common choices in routine assessments of anthropometric status in young children.
