A cross-sectional study was done in 2008-2009 to assess sodium salt intake in adults living in Hanoi capital, Thua Thien Hue province, and Ho Chi Minh city. Total of 1,518 subjects participated into study. Seasoning intake was evaluated by weighing method at household. Sodium content in seasonings was assessed by High-perfonnance liquid chromatography (HPLC) method, then sodium salt content in the seasoning was calculated based on molecular weight of NaCl. Therefore, sodium salt intake was equal to amount of seasonings multiply with content of sodium salt in the seasonings. Results showed that, mean sodium salt intake in studied subjects was 11.7 + or - 5.5 g/day. There was no significant difference of salt intake between urban and rural areas. Mean sodium salt intake in males (12.7 g/ day) was higher than that in females (10.5 g/ day), p 0,05. The intake was highest in Thua Thien Hue (12.3 g/ day), followed by Ho Chi Minh city (11.1 g/ day) and Hanoi (10.7 g/ day). In conclusion, sodium salt intakes in adults in studied sites were 2 times higher than recommendation of World Health Organization. Intervention studies should be done in future to reduce salt intake in order to control high blood pressure in community.
