Undernutrition can cause vitamin-deficiency-related diseases like scurvy and rickets. As undernutrition worsens, those affected have less energy and experience impairment in brain functions. This can make it difficult (or impossible) for them to perform the tasks needed to acquire food, earn an income, or gain an education. [citation needed]
Studies have found a strong association between undernutrition and child mortality. [15] Once malnutrition is treated, adequate growth is an indication of health and recovery. [ 5 ] Even after recovering from severe malnutrition, children often remain stunted for the rest of their lives.
Maternal undernutrition increases the chances of low-birth weight, which can increase the risk of infections and asphyxia in fetuses, increasing the probability of neonatal deaths. [128] Growth failure during intrauterine conditions, associated with improper mother nutrition, can contribute to lifelong health complications. [ 3 ]
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 in varying proportions. The condition has mild, moderate, and severe degrees.
It provides organisms with nutrients, which can be metabolized to create energy and chemical structures. Failure to obtain the required amount of nutrients causes malnutrition. Nutritional science is the study of nutrition, though it typically emphasizes human nutrition. The type of organism determines what nutrients it needs and how it obtains ...

[23] Hunger is most commonly related to poverty since a lack of food helps perpetuate the cycle of poverty. Most obviously, when individuals ...
Micronutrient deficiencies are considered a public health problem worldwide. For over 30 years it has been estimated that more than two billion people of all ages are affected by this burden, [1] while a recently published study based on individual-level biomarker data estimated that there are 372 million children aged 5 years and younger, and 1.2 billion non-pregnant women of reproductive age ...
An ecological study is an observational study that studies risk-modifying factors on health outcomes of populations based on their geographical and/or temporal ecological state. Ecological studies are useful in studying patterns of disease in large populations however may not accurately reflect true associations between individuals within those ...
