Anemia can be classified based on different parameters, and one classification depends on whether it is related to nutrition or not so there are two types: nutritional anemia and non-nutritional anemia. [1] Nutritional anemia refers to anemia that can be directly attributed to nutritional disorders or deficiencies.
A strict but broad definition is an absolute decrease in red blood cell mass, [63] however, a broader definition is a lowered ability of the blood to carry oxygen. [64] An operational definition is a decrease in whole-blood hemoglobin concentration of more than 2 standard deviations below the mean of an age- and sex-matched reference range. [65]
Primary polycythemias are myeloproliferative diseases affecting red blood cell precursors in the bone marrow. Polycythemia vera (PCV) (a.k.a. polycythemia rubra vera (PRV)) occurs when excess red blood cells are produced as a result of an abnormality of the bone marrow. [3] Often, excess white blood cells and platelets are also produced.
Nutritional epidemiology is the scientific basis upon which public health nutrition is built. [6] Nutritional epidemiology aims to deliver knowledge on how to cope with an imbalance between nutrients that causes illness such as anaemia, goitre wasting and stunting. The understanding of the characteristics of exposures require measurement to ...
Macrocytic anemia is a class of anemia characterized by the presence of predominantly larger-than-normal red blood cells (RBC, also known as erythrocytes) accompanied by low numbers of RBC and often also with insufficient hemoglobin content per cell. Macrocytic anemia occurs when – despite the larger cell size – such factors result in ...
Research on overcoming persistent under-nutrition published by the Institute of Development Studies, argues that the co-existence of India as an 'economic powerhouse' and home to one-third of the world's under-nourished children reflects a failure of the governance of nutrition: "A poor capacity to deliver the right services at the right time ...

Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
