Adolescents make up as much as a quarterof the population and the number of adolescents is expected to rise through 2050. Adolescents are vulnerable to the riskfactors contributing to Noncommunicable diseases, whether from unhealthy diets, physical inactivity, exposure to tobaccosmoke or the harmful use of alcohol.Method: A cross sectional analytical study design was used among 89 adolescents of grade 9 and 10 was selected throughenumerative sampling technique. Data was collected using a self–administered questionnaire from Adolescent HealthPromoting – Short Form scale and entered in excel and analyzed by Statistical Package for Social Science (SPSS) version20.0 using Descriptive statistics (Frequency, percentage, mean, standard deviation) and interferential statistics (chi-square).Result: Findings revealed that 48.3% respondents obtained below average mean score on health promoting behaviour.The overall mean ± S.D of status of health promoting behaviour was 68.12±8.847. Among 6 subscales, life appreciationobtained the highest mean score (with standard deviation) i.e. 15.35±3.72, whereas exercise obtained least mean score (withstandard deviation) i.e. 7.80±2.66 and there is statistically significant association with health promoting behaviours amongadolescents and educational status of mother (p=0.033).Conclusion: Overall health promoting behaviours among adolescents is below average so it is necessary to improve in areaslike nutrition and exercise. There is significant association between parental education and health promoting behavioursof the adolescents, so parental education should be improved by school committee, should introduce educational session,awareness program, physical activity program and nutrition exhibition program regarding health promoting behaviourssince early grade.
