Abstract: Reproductive health and behaviour of adolescents is an increasingly important component for the healthy nation. Adolescence, the second decade of life is a period when young people acquire new capacities for progress with physical growth, physiological and psychological change, the development of secondary sexual characteristics and reproductive maturation. Young people worldwide, however, face social, economic and health challenges that were unimaginable. Adolescence is, therefore, considered as a phase rather than a fixed age group; with physical, psychological, social and cultural dimensions. Programmes that can provide information, ensure access to services, and develop life skills are crucial to the future of this population. This paper will explore the existing practices or information on sexual and reproductive behaviour among adolescent girls’ of Meitei-Pangals in Imphal East, Manipur; in relation with the knowledge and attitudes, socio-economic and cultural factors operating within, as well as their perception and awareness level pertaining to the health care services.
