Introduction: In recent times, the non–communicable diseases (NCDs) have attained a magnitude of epidemic proportion, with increasing number of adolescents being reported as obese. The risk factors for NCDs such as obesity, sedentary lifestyle, unhealthy dietary habits etc., are inculcated during the adolescence and continue to exist into adult life. Thus, lessening the associated risk factors is an important way to reduce the NCDs. Aim and objectives: To study the pattern of physical activity and its association with anthropometric risk factors for NCDs among school–going adolescents in a rural block of Haryana. Material and Methods: A cross–sectional study was conducted in Lakhanmajra block of Rohtak district over a period of one year from July 2016 to June 2017. A total of 750 students from six co–educational government senior secondary schools were included in the study. Data were collected using pre–designed, pre–tested, semi–structured interview schedule and analysed using SPSS version 20.0. Results: 61.74% adolescents were involved in different physical activities like jogging/walking, cycling and playing for one hour or more. 11.2% of the study subjects had anthropometric risk for developing NCDs based on waist circumference and waist hip ratio criteria. Conclusion: The anthropometric risk factors for NCDs among adolescents are on an increasing trend in rural areas. Thus, it is the need of the hour to address this problem and devise programs and strategies to prevent development of NCDs in children and adolescents.
