ASSESSMENT AND REQUIREMENTS OF NUTRITION IN
DIFFERENT AGE GROUPS
INTRODUCTION
Nutrition is a biochemical process through which the body obtains energy and
structural components necessary for growth, maintenance, and repair. The
nutritional needs of humans vary at diferent stages of life due to changes in growth
rate, metabolic activity, hormonal balance, and physiological demands. Nutritional
chemistry provides the molecular understanding of nutrients, their chemical
structure, metabolic pathways, and biological functions. Growth is a complex
process infuenced by both nutritional and non-nutritional factors. Proper
nutritional assessment, combined with an understanding of chemical functions of
nutrients and factors infuencing growth, is essential for achieving optimal physical
and mental development throughout the life cycle
NUTRITIONAL ASSESSMENT
Nutritional assessment is the scientifc evaluation of an individual’s nutritional
status using anthropometric, biochemical, clinical, and dietary data. It helps in
identifying nutrient defciencies, excess intake, and metabolic disturbances. From a
nutritional chemistry perspective, assessment correlates dietary intake with
biochemical reactions such as enzyme activation, ATP synthesis, and hormonal
regulation.
ABCD METHOD
1.Anthropometric Assessment
Anthropometric measurements such as weight, height, BMI, head circumference,
and skinfold thickness refect growth patterns and body composition. These
parameters indirectly indicate the adequacy of nutrients required for anabolic
processes like protein synthesis and bone mineralization.
, 2.Biochemical Assessment
Biochemical tests measure nutrient concentrations and metabolic indicators,
including hemoglobin, serum ferritin, calcium, vitamin D, and serum proteins.
These markers provide direct evidence of biochemical alterations caused by
nutritional imbalances and impaired metabolic pathways.
3.Clinical Assessment
Clinical examination identifes physical signs of nutrient defciencies such as pallor,
edema, bone deformities, and skin lesions. These symptoms result from altered
biochemical reactions, reduced enzyme activity, and disrupted cellular
metabolism.
4.Dietary Assessment
Dietary assessment evaluates nutrient intake through food recall and dietary
records. It helps determine whether macro- and micronutrients are consumed in
sufficient quantities to meet biochemical and physiological requirements.
