Background: Moderate population salt reduction could reduce blood pressure and the cardiovascular and stroke mortality in the long-term. In 2002, China’s national average dietary salt intake is twice of the recommendation sodium intake limit by Chinese Nutrition Association. To tackle the health burden of excessive salt intake, the former Ministry of Health has chosen Shandong province as national pilot and launched the Shandong & Ministry of Health Action on Salt and Hypertension (SMASH, 2011[[Unable to Display Character: –]]2015) project.
Objective: To develop and target intervention priority, a cross-sectional population survey was conducted to collect baseline data on sodium intake and sources in Shandong adults in 2011.
Methods: We used multi-stage clustering sampling method to select the provincial representative sample for Shandong adults aged 18~69 years old. The selected adults were invited to participate the questionnaire survey and consecutive three-round 24-hour dietary recall. The Chinese 24-hour dietary recall includes two parts, cooking condiment weighting and the food (exclude the condiment) intake diary. The sodium contents in the condiments and food were calculated by using reference values from China Food Composition 2004.
Results: Overall, 2140 community adult residents were included in the data analysis. The total average dietary sodium intake estimated by 24-hour dietary recall was 5745mg (95%CI: 5428-6063). Men (6147mg/d, 5824-6471) consumed higher sodium than women (5339 mg/d, 5006-5673) (P<0.05). The majority of dietary sodium (81%) was from cooking condiments including salt, soy sauce, sauce and monosodium glutamate (MSG), with a mean sodium intake of 4640mg (4360-4920). Out of the cooking condiments, salt added during food preparation was the leading source (63%) of sodium intake, up to 3638mg/d (3397-3879) sodium intake. Sodium intake from processed food was account for 10% of the total sodium intake, averaged at 582 mg (498-666) sodium intake for Shandong adults.
Conclusion: The Shandong adults consume excessive sodium than the recommendation intake and most is from the condiments added at cooking.
