This imbalance includes both inadequate and excessive energy intake; the former leading to malnutrition in the form of wasting, stunting and underweight, and the latter resulting in overweight and obesity.
Deficiencies of macronutrient and micronutrient adversely affect growth, body composition, muscle strength, intelligence, body development and quality of life in the pediatric age group.
In children, under nutrition manifests as underweight and stunting (short stature), while severely undernourished children present with the symptoms and signs that characterize conditions known as kwashiorkor, marasmus or marasmic-kwashiorkor.
Malnutrition generally implies under nutrition and refers to all deviations from adequate and optimal nutritional status in infants, children and in adults.
Deficiency in macronutrients such as protein, carbohydrates and fat provoke protein-calorie malnutrition (PCM), and when combined with micronutrient deficiencies, they are among the most important nutritional problems with hundreds of millions of pregnant women, elderly and young children particularly affected.

On the other hand infection causes loss of important micro and macro nutrients leading to alter nutritional levels.
Malnourished children acquire bacterial gastrointestinal and respiratory infections more frequently. 42. Malnutrition significantly compromises mucosal epithelial barriers in the gastrointestinal, respiratory and urogenital tracts which are first line of defense against infections.
