Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. [11] [12] Specifically, it is a deficiency, excess, or imbalance of energy, protein and other nutrients which adversely affects the body's tissues and form. [13] Malnutrition is a category of diseases that includes undernutrition and ...
On average, adults who were malnourished as children can earn an estimated 20% less than those who weren't malnourished as children. Due to the effects of malnutrition in developing countries, losses in GDP can add up to 2-3% annually. Malnutrition is estimated to cost $20–$30 billion per year globally.
Endocrinology. Protein–energy undernutrition (PEU), once called protein-energy malnutrition (PEM), is a form of malnutrition that is defined as a range of conditions arising from coincident lack of dietary protein and/or energy (calories) in varying proportions. The condition has mild, moderate, and severe degrees.
Physiologist Ancel Keys was the lead investigator of the Minnesota Starvation Experiment. He was directly responsible for the X-ray analysis and administrative work and the general supervision of the activities in the Laboratory of Physiological Hygiene which he had founded at the University of Minnesota in 1940 after leaving positions at Harvard's Fatigue Laboratory and the Mayo Clinic.
Protein-Energy Malnutrition (PEM) is another form of malnutrition that affects children. PEM can appear as conditions called marasmus, kwashiorkor, and an intermediate state of marasmus-kwashiorkor. Although malnutrition can have severe and lasting health effects on women and children, they are still susceptible to other water-related dangers. [10]
Failure to thrive (FTT), also known as weight faltering or faltering growth, indicates insufficient weight gain or absence of appropriate physical growth in children. [ 2 ][ 3 ] FTT is usually defined in terms of weight, and can be evaluated either by a low weight for the child's age, or by a low rate of increase in the weight. [ 4 ]
Stunted growth, also known as stunting or linear growth failure, is defined as impaired growth and development manifested by low height-for-age. [1] It is a primary manifestation of malnutrition (or more precisely chronic undernutrition) and recurrent infections, such as diarrhea and helminthiasis, in early childhood and even before birth, due to malnutrition during fetal development brought ...
Stunted children are more likely to develop obesity and chronic diseases upon reaching adulthood. [105] Therefore, malnutrition resulting in stunting can further worsen the obesity epidemic, especially in low and middle income countries. [105] This creates even new economic and social challenges for vulnerable impoverished groups. [105]
