In Viet Nam, the Central Highlands, with their diverse ethnic minority population, show the lowest CPR in the country (Teerawichitchainan, 2008, UNFPA, 2009). Supply and demand side barriers hampering access and use of contraceptives among disadvantaged groups are many, such as costs, distance to service delivery points and lack of information and knowledge, as well as cultural and social values (Sdortino, 2008). According to estimates, in South and South-East Asia in the 2000-2005 period 11 per cent of married women of reproductive age had an unmet need for contraception both for spacing and limiting births.
