Social and cultural changes in Nepal, including better communication facilities and transport, more urbanization and a rising age at which people marry, have created more opportunities for young people for "dating." Our qualitative study explores whether the existence of dating cultures influences young people's sexual behavior in Nepal. Focus group discussions with a total of 75 participants and 31 in-depth individual interviews were conducted among young people in Nepal. Most urban and rural young people liked the dating culture. Although it is a new kind of culture in Nepalese society, it is gaining popularity. The mass media were regarded as encouraging and creating an environment for dating. Most participants believed that dating culture encourages premarital and extramarital sexual behavior. The authors underpin their findings by linking it to the "emerging adulthood" framework. In terms of public health, they recommend that dating practice should be discussed in formal and informal education to promote safer sex. (Contains 2 tables.)
