What is biological age (SMR) and why should it be used instead of chronological age to determine adolescent nutrient needs?

Biological age is based on sexual maturation rating. It assesses the degree of physical development, which can vary greatly among individuals of the same gender and age, thus is a better indicator of the nutrient needs of individuals as it provides a physiological estimate of needs based on growth velocity, body composition, and reproductive capacity.

Summary Introduction

To discuss: The description of biological age and the advantages of using biological age over chronological age to determine adolescent nutrient needs.

Introduction: Adolescence is the time period when a child develops into an adult. It is characterized by increased growth and development of secondary sexual characteristics that highly influence the nutritional needs of the body. There is an increased demand for essential micronutrients and macronutrients in the body. Therefore, individuals must ensure proper nutrition during this period as it can have long-term effects on their health and also prevent health problems.

Explanation

The biological age is determined on the basis of sexual maturity ratings (SMRs). SMR is based on an individual’s physical development during puberty. It is generally divided into five stages also known as Tanner stages on the basis of the level of secondary sexual characteristic development in individuals...
