Secular trends in salt and soy sauce intake among Chinese adults, 1997–2011

Abstract

Salt and soy sauce are the main ways of sodium intake in Chinese dietary. In this study, we used the data of the China Health and Nutrition Surveys to describe the secular trends of salt and soy sauce intake among Chinese adults from 1997 to 2011. Trends were tested by multiple linear regression models. During the past 14 years, the consumption of sodium, salt and soy sauce intake values decreased significantly across the six study periods (p < .0001) among both men and women. Averaged salt values decreased by 4.9 g/d in men and 4.1 g/d in women. Mean soy sauce intake values decreased by 9.0 g/d among men and 7.3 g/d among women. Similar significant trends were observed in all age groups, activity levels and regions (p < .0001).
