Which of the following growth parameters is used as a screening tool for assessing underweight and overweight or obesity in young children? a. Weight-for-age percentile b. Length- or stature-for-age percentile c. Body mass index-for-age percentile d. Actual body mass index (weight in kg/height in meters2) e. Actual weight in kg

Summary Introduction

Introduction: Growth parameters are assessed at birth which helps to predict subsequent growth and development and risk of disease in young children. It also helps to identify the risk of neonatal pathology. The parameters include weight, length, and head circumference. Based on these parameters various growth chart is developed.

Explanation

Reason for the correct answer:

Option c. is given as “Body mass index-for-age percentile”

Body mass index (BMI) is a rough indicator of body fat in children. In children, their normal growth is usually accompanied by an increase and decrease in body mass index (BMI) with age. Therefore, BMI-for-age percentile can be used to determine weight status on children on the basis of their weight, age, and height with respect to other children. Therefore, it is the most common screening tool to assess underweight and overweight or obesity in young children.

Hence, option c. is correct.

However, weight is not the only factor that can be used to determine weight status of a child. It must also take into consideration their height as two children of the same age and same weight can have very different weight status depending on their height.

Hence, option a. is a wrong answer.

Option b. is given as “Length- or stature-for-age percentile...
