title: Changing family formation in Nepal: marriage, cohabitation and first sexual intercourse.
abstract: BACKGROUND
  In Nepal, marriage occurs at a relatively young age and arranged weddings are widespread. However, recent changes in the family formation process and the timing of first sexual intercourse suggest that a transformation may be under way.
  
  
  METHODS
  Data on marriage, cohabitation and first sexual intercourse from the 2001 Nepalese Demographic and Health Survey were used to describe the family formation process. The sequence of these events and the intervals between them were explored for currently married men and women. Hazard models were used to identify factors associated with behavioral changes over time.
  
  
  RESULTS
  The average age at marriage among women married before age 20 increased from 13.7 years for those born in 1952-1956 to 15.6 years for those born in 1977-1981, while remaining relatively stable for men married before age 25 (17.3 years for the 1942-1946 birth cohort to 17.7 for the 1972-1976 birth cohort). After individual and couple characteristics were controlled for, younger age at interview was associated with greater odds of simultaneous marriage and cohabitation for both genders (odds ratios, 1.3-1.7). Younger age at interview was also associated with premarital sex among men--those aged 39 or younger had significantly higher risks than older men of having had premarital sex, with odds ratios rising from 1.6 among those aged 35-39 to 1.8 among those aged 15-24.
  
  
  CONCLUSIONS
  It is important not only to promote education as a means of delaying marriage and childbearing, but also to implement programs and services that prevent reproductive health problems for young married couples.
