As the most vulnerable segment of the population, children under the age of five
serve as a critical indicator of community health and nutrition. They are usually
impacted by PEM as a result of a lack of nutrients to meet their needs. Malnutrition
affects children under the age of five, primarily in disadvantaged settings. Kwashiorkor
generally affects children between the ages of one and three, while marasmus primarily
affects children under the age of two. Despite slight progress over the years, India has
the highest rate of stunting, according to the National Family Health Survey
(NFHS)-4(2015-16). In India, 38.4 percent, 35.8 percent, and 21% of children were found
to be stunted, underweight, or wasting in 2015-16, respectively, but in Odisha, the
percentages were 38.2 percent, 34.4 percent, and 18.3 percent. Malnutrition is caused by
a lack of access to highly nutritious foods, poor feeding practices such as
non-exclusive breast feeding, poor environmental conditions, large family size, poor
maternal health, premature babies, negative cultural practices related to child rearing
and weaning, delay in introducing supplementary feeding, and high female illiteracy.
Malnutrition is exacerbated by frequent diseases such as diarrhea, respiratory
infections, measles, and intestinal worms [1]. Malnutrition is responsible for more than
a third of all child fatalities. Malnutrition causes long-term impairments such as lower
labour ability, growth retardation, and poor social and mental development in later
life. Malnutrition causes mortality, disability, stunting, and mental and physical
development retardation in children. A systematic review of published publications was
conducted primarily using secondary sources of literature from internet databases such
as Research Gate and Google Scholar. The articles were picked based on important
subjects such as assessing various forms of malnutrition and the variables that
influence it. The goal of the research, titled "Prevalence of Protein Energy
Malnutrition among Under-five Children in Odisha" was to learn more about the
prevalence of malnutrition and the variables that influence it
