Background: The most common cause of anaemia in children is nutritional deficiency of iron, vitamin B12 and folic acid. Elderly patients with anaemia are heterogeneous in terms of clinical history, co-existing medical conditions, and concomitant medication use than young adults. Anaemia is a serious global nutritional issue. At least one-third of the population is thought to have experienced anaemia at some point. Aim and Objective: To study the clinico-pathological patterns of anaemia in children in the age group ranging from 3 years to 15 years. Methodology: The current study is a cross-sectional, descriptive analysis of 300 patients with anaemia who were hospitalized to the paediatric ward of Santosh Hospital in Ghaziabad between the ages of 3-15 years. During physical examination following signs and symptoms were noted: Pallor, edema, clubbing, skin problem (dryness, rashes, and irritation), abnormal pigmentation, coarse hair, puffiness of face, thinning of eyebrows, nail defects, ulceration, abnormalities in genitalia, hand and feet abnormalities, nose, eyes, cranium, ear and face. Result: Anaemia was defined as having a haemoglobin level below 11.2 g/dl in children. Anaemia was prevalent in 56.6% of the population. Low weight, young age, and a diagnosis of acute lower respiratory disease were all substantially associated with anaemia. There was no correlation found between gender distribution and anaemia severity. Conclusion: Children need to be screened early for anaemia and related disorders because they are the group most at risk for nutritional deficiencies. Early diagnosis and suitable care are made possible by initial screening and later diagnostic procedures
