The most commonly used method in Viet Nam is the intrauterine device (IUD), which was being used by 39 and 38 per cent of currently married women in 1997 and 2002, respectively, followed by withdrawal (11.9 per cent in 1997 and 14 per cent in 2002). Despite the predominance of IUD as the leading method in Viet Nam, use of it has actually declined slightly (about one percentage point) during the period 1997-2002. Conversely, the use of contraceptive pills has increased slightly (from 4 to 6 percentage points) during the same period. Unlike other countries, it lias been found that the use of traditional methods and pills has increased in Viet Nam while female sterilization and condom use have decreased.
