Abstract
To understand the current status and food sources of salt and sodium intake among adult residents in 16 provinces(autonomous regions and municipalities) of China.
The data were derived from 2022-2024 "China Development and Nutrition Health Impact Cohort Survey", and adults(≥18 years) with complete demographic characteristics and dietary data were selected as study subjects. Salt and sodium intake levels and main food sources among adult residents of different genders, ages, residential areas, and regions were analyzed. Compared the outcome with the recommended nutrient intake and preventive intake for non-communicable disease(PI-NCD), to assess the intake status.
The median total salt intake of adult residents in 16 provinces(autonomous regions and municipalities) was 8.5 g/d, the median cooking salt intake was 6.4 g/d, the median sodium salt intake was 1.5 g/d, 76.9% of the population had a total salt intake exceeding the recommended intake of 5 g/d. The median total sodium intake reached 4230.9 mg/d, with 87.7% of residents exceeding the PI-NCD, and 87.1% exceeding the upper limit of 2000 mg/d recommended by the WHO. The salt and sodium intake were relatively higher in males, northern residents, and residents of rural areas, and the proportion of sodium intake exceeding PI-NCD was relatively higher in the 65-74 age group. The main source of total salt and sodium intake was cooking salt.
The problem of high salt and high sodium diets among Chinese adult residents remains prominent, with intake levels far exceeding the recommended standards. There are significant demographic and regional distribution differences.
