Adolescence is a transitional phase from childhood to adulthood. It is a period of development as the gain of anthropometric measurements is increased over this period. India is a country with different tribal groups and Bastar district is a tribal belt of Chhattisgarh state in India. The nutritional status is a major concern among adolescent girls, which affects growth and development and forms basis of adulthood, dietary supplements can play an important role to address the concerns. The study aimed to explore the effect of soy supplement on the anthropometric measurement of tribal girls. A total of 120 female players aged 12 to 18 years from a residential school where the female players take part in sports training as well as attend the school Khel Parisar Kanker (KPK) from the tribal area and female players of Sports Authority of India (SAI) of urban area were selected for the study. Female players of KPK and SAI were divided into Experimental Group (EG) (N=30) and Control Group (CG) (N=30). Soy Supplement in form of Soy Ladoo was provided to the experimental group from August’2018 to March’2019. Before and after experimental design with control groups was used in the study. Height, Weight, Mid Upper Arm Circumference (MUAC), Waist Girth (WG) were measured and BMI was calculated. ANCOVA and trend analysis were used to analyse the data. It was found that Anthropometric measurements (MUAC, WG and BMI)increased significantly in EG than CG in KPK and SAI female players. An upward trend was observed and can be concluded that soy supplement was effective in improving anthropometric measurements.
