Background: Anaemia is one of the most common nutritional deficiency disorders in the world. In Garhwa district (tribal area of Jharkhand) inadequate dietary iron, folate intake, low Vitamin B12 intake due to low vegetables consumption are the major factors responsible for high prevalence of anaemia. This study was done therefore to assess the prevalence of anaemic patients and to classify them according to their age, sex and severity of anaemia. Materials & methods: The data of anaemic patients has been obtained from Haematology laboratory of Vananchal Dental College & Hospital, Garhwa, Jharkhand. Age, sex and Haemoglobin (Hb) values of patients who came for routine examination from August 2016 to February 2017 were noted. From the Hb values, presence or absence of anaemia and grading of anaemia was assessed. The grading of anaemia is divided into three types: Mild, Moderate and Severe anaemia. Results: Out of total 635 patients reported, 500 (78.7%) were found anaemic. Among the 500 anaemic patients, 314 were females (62.8%) and 186 were males (37.2%). Most of the anaemic patients (52.2%) were in the age group of 21-30 and 31-40 years. Out of 500 patients, 375 patients (75%) had mild (Hb%: 10-12.9%), 93 patients (18.6%) had moderate (Hb%: 7- 9.9%) and 32 patients (6.4%) had severe anaemia (Hb%: <7%). Conclusion: Anaemia is commonly prevalent in this tribal region of India. Females as well as people of the age group of 21-30 and 31-40 years are more affected and patients are mainly suffering from Mild and Moderate grades of anaemia.
