OBJECTIVE

To analyze salt intake among Chinese aged 60 and above in2010- 2012.

METHODS

Data was from 2010- 2012 Chinese Nutrition and Health Surveillance. Salt and condiment intake information of Chinese elderly was collected by the 3-condecutive days-24-hour dietary recall and food weighting method, the average salt intake was calculated based on energy percentage of family members.

RESULTS

The daily average salt intake of Chinese elderly was( 8. 8 ± 6. 8) g / d, the level was( 9. 5 ± 7. 2) g / d for male and( 8. 2 ± 6. 3) g / d for female, ( 7. 9 ± 6. 2) g / d for urban areas and( 9. 9 ±7. 2) g / d for rural areas. Salt intake among the elderly in big cities, medium-sized and small cities, general rural and poor rural was( 7. 3 ± 5. 8) g / d, ( 8. 6 ± 6. 6) g / d, ( 9. 9 ±6. 9) g / d and( 10. 1 ± 7. 9) g / d, respectively. The average daily salt intake decreased with increasing age and also declined with the increase of per capita annual income, while the average daily intake of salt increased from illiteracy to primary school and thendecreased in junior middle-school or above. Compared with the salt recommendation( less than 6g / d) from Chinese residents dietary guidelines 2016 edition, there were only37. 7% of elderly meet with salt recommendation, 41. 0% of participants were in the level between 6 g to 11 g, and 21. 4% were higher than 12 g. Urban participants whose salt intake were less than 6 g, 6 g to 11 g and higher than 12 g accounted for 43. 4%, 40. 3%and 16. 3%, while in rural areas these percentage were 30. 7%, 41. 7% and 27. 6%, respectively.
