Vitamin D is known as anti-ricketic factor or sunshine vitamin. The uniqueness of Vitamin D is that it can be synthesized by the body and it functions as a hormone. Apart from various other metabolic functions, it plays a pivotal role in calcium homeostasis and bone mineral metabolism, which effects the longitudinal growth in children. The comparative study was carried out to determine the possibility of a relationship between the presence of Playgrounds in schools and impact on the heights of the female students of age 13-15 years, in Hyderabad. 10 schools were selected (5 each with and without Playground) for a cross-sectional study. A total of 300 participants were assessed for height and interviewed regarding various Sun-Exposure factors. The data collected was compared with IAP standards using Height for Age Charts The Average heights of students observed in schools with and without Playground facilities were recorded as 152 ± 9 cm and 146 ± 13 cm for the 13 year old, 154 ± 7 cm and 149 ± 14 cm for 14 year olds, 156 ±8 cm and 152 ± 12 cm for 15 year olds respectively. Ample Sunlight availability in India should have helped to meet the Vitamin D requirement especially among growing children. Lack of awareness, social restrictions, traditional practices, indifferent attitude towards outdoor activity in schools and home, gender bias play a significant role in decreasing Sunlight exposure in Indian female adolescents
