Introduction
Anemia is a major problem affecting all age groups across the world. Anemia is a clinical condition in which there is decreased red blood cell count and hemoglobin levels.1 Anemia is prevalent in about one fourth population of the world.2 Anemia plays an important role in morbidity and mortality among children.3 Anemia is a manifestation and not a disease per se. Malnutrition is the most common cause of anemia among children. Nutritional anemia due to iron deficiency, vitamin B12 or folic acid deficiency and hookworm infestation can be easily prevented and treated.4 Routine investigations like complete blood count and Peripheral smear are useful to investigate case of anemia.
Materials and Methods
The study was conducted on 200 cases among children aged between 6 months and 5 years who were referred to Hematology laboratory, department of Pathology at Mysore medical college and research institute for a duration of 3 months.
The anticoagulated blood samples were analyzed by an automated counter Sysmex XN 1000. RBC parameters like RBC count, Hemoglobin, Hematocrit, Mean cell volume, Mean cell hemoglobin, Mean cell hemoglobin concentration and Red cell distribution width were studied.
Results
The cases were in the age group between 6 months and 5 years. A total of 200 cases with hemoglobin less than 11g/dl were included in the Prospective study group.
Table 1
| Morphology | No.of Cases | Percentage |
| Normocytic normochromic anemia | 41 | 20.5% |
| Normocytic hypochromic anemia | 38 | 19% |
| Microcytic hypochromic anemia | 102 | 51% |
| Macrocytic anemia | 4 | 2% |
| Dimorphic anemia | 15 | 7.5% |
The following patterns were observed:

Comparison of morphological types of anemia
116 cases (58%) were males and 84 cases(42%) were females. So majority of the males were affected by anemia (Table 2 ) and is similar to the study conducted by Gombur.5
Our study results are compared with study done by Rathna S6 et al. The commonest morphological type observed was Microcytic hypochromic anemia (51%) followed by Normocytic normochromic anemia (20.5%) as shown in (Table 3)
The anemia was subtyped again based on the morphology as shown in (Table 1). The morphological categories given were
Discussion
Anemia has high prevalence in preschool children. The most common cause of anemia in Paediatric age group is Iron deficiency anemia which is associated with Microcytic hypochromic pattern. So supplementing with iron tablets and syrups, iron rich diet will prevent and treat the cause.7
In these days due to modern lifestyle people are prone to nutritional anemia. The most common types of anemia are Microcytic hypochromic anemia (63%) followed by Normocytic normochromic anemia (24%), Normocytic hypochromic anemia (9%), and Dimorphic anemia8
Approximately 50% of the population suffers from nutritional anemia as known in countries where meat consumption is low9
In our study male were more affected than female children. This is similar to studies conducted by Roosy Aulakh, et al10 included 151 children with 106(70.2%) boys and 45(29.8%) girls.
Conclusion
Anemia is a major health issue among children as it is associated with delayed milestones, recurrent illness, increased mortality and morbidity.
Routine screening programs using cost effective basic blood parameters are useful to detect and treat anemia among vulnerable children.
Study of morphology is useful to know the causative factors and hence provides information to prevent and treat anemia.
Special investigations like serum iron profile, vitamin B12 & folic acid assays are useful for further workup to diagnose nutritional anemia. Suitable investigations like Hemoglobin electrophoresis and bone marrow study are useful to confirm the diagnosis and to guide treatment.
