A baby’s weight at birth is a strong indicator of maternal and newborn health and nutrition. Being undernourished in the womb increases the risk of death in the early months and years of a child’s life. Those who survive tend to have impaired immune function and increased risk of disease; they are likely to remain undernourished, with reduced muscle strength, cognitive abilities and IQ throughout their lives. As adults, they suffer a higher incidence of diabetes and heart disease. Hence based on above findings the present study was planned for Evaluation of Fetal Malnutrition by Clinical Assessment of Nutritional Status Score (CAN Score) and Anthropometric Indices. The present study was planned in Department of Pediatrics, Darbhanga Medical College and Hospital, Darbhanga, Bihar during the period of June 2019 to February 2020. Total 100 cases of new borns delivered in our hospital were enrolled in the present study. The following parameters were recorded in all babies (Weight was recorded at birth, clinical assessment of nutrition score, length, mid arm circumference and head circumference were recorded between 24-48 hrs of life). Nude birth weight was recorded using electronic weighing scale. Length was measured using infantometer. Mid arm circumference (MAC) was measured in the left arm at a point midway between tip of the acromion and the olecranon process. Head circumference (HC) was taken at the largest circumference of skull using a non-stretchable tape. The data generated from the present study concludes that classifying babies on basis of weight as SGA, AGA and LGA may miss to diagnose some of the cases who are affected very late in third trimester. CAN Score is a simple systematic method to identify fetal malnutrition. It does not require any sophisticated equipment’s or time-consuming calculations. Hence it is the method preferred for/ ideal for screening malnourished babies.
