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).
盐和酱油是中国人饮食中钠的主要摄入途径。在这项研究中，我们使用了中国健康与营养调查的数据，描述了 1997 年至 2011 年期间中国成年人盐和酱油摄入量的长期变化趋势。采用多元线性回归模型进行趋势检验。在过去的 14 年中，男性和女性在六个研究期间的钠、盐和酱油摄入量均显著下降（p<0.0001）。男性平均盐摄入量下降了 4.9 g/d，女性下降了 4.1 g/d。男性平均酱油摄入量下降了 9.0 g/d，女性下降了 7.3 g/d。在所有年龄组、活动水平和地区都观察到了类似的显著趋势（p<0.0001）。
