Question

Which of the following is the best sign to indicate adequate growth in an infant with a birth weight of 2.8 kg?

• A. Increase in length of 25 centimetres in the first year
• B. Weight gain of 300 grams per month till 1 year
• C. Anterior fontanelle closure by 6 months of age
• D. Weight under the 75th percentile and height under the 25th percentile

Answer 1

The Correct Option is A

To determine the best indicator of adequate growth in an infant with a birth weight of 2.8 kg, we consider the typical growth parameters for infants during their first year. One key aspect of infant growth is the increase in length and this is widely used by pediatricians as an indicator of overall growth and development.

Infants generally grow rapidly during their first year. The typical expectation is an increase in length by approximately 25 centimeters from their birth length. This increase reflects healthy growth and development as long as it aligns with the established growth charts and percentiles for infants.

By evaluating the options provided:

Options	Assessment
Increase in length of 25 centimetres in the first year	Consistent with expected growth patterns, indicating adequate growth.
Weight gain of 300 grams per month till 1 year	This rate of weight gain might be lower than the typical expectation, as infants generally gain about 150-200 grams per week initially.
Anterior fontanelle closure by 6 months of age	Fontanelle closure time varies widely among individuals and is not a primary indicator of overall growth.
Weight under the 75th percentile and height under the 25th percentile	This indicates disproportionate growth, which may not reflect adequate or balanced development.

Among the provided options, "Increase in length of 25 centimetres in the first year" is the best sign of adequate growth for an infant, aligning with typical pediatric growth standards.
