Abstract:
Objective:To estimate the deaths and life expectancy losses attributed to diet with high salt in Shandong province.Methods:Based on 24 h urinary sodium and blood pressure levels from the final evaluation survey of Shandong-Ministry of Health Action on Salt and Hypertension Project (SMASH) in 2016 and death cause data from Shandong Mortality Surveillance System, the population attributable fractions (PAF) and the deaths due to high-salt diet were calculated based on the framework of comparative risk assessment and the life expectancy loss was calculated by life table method.Results:A total of 32 987 deaths caused by high-salt diets were reported in 2016, accounting for 11.74% of related disease deaths and 4.95% of all deaths. The proportion of deaths due to high-salt diet in men (13.51%) was higher than that in women (9.17%). Cardiovascular diseases were the major causes of deaths due to high salt diet, accounting for 90.82% of all disease deaths caused by high-salt diets. The other causes were gastric cancer (8.10%) and chronic kidney disease (1.08%). The PAF in urban residents (13.87%) was higher than that in rural residents (10.87%). A loss of 0.58 years of the life expectancy were attributed to the high-salt diet. The different diseases caused by high-salt diet had different effects on life expectancy loss, ischemic heart disease ranked first, followed by cerebral hemorrhage and cerebral infarction.Conclusions:The proportion of deaths attributed to high-salt diets was high in Shandong. Cardiovascular diseases were the most important causes of deaths caused by high-salt diets. High-salt diet is still seriously affecting the health of residents in Shandong, indicating that salt reduction interventions need to be strengthened.
