The effect of dietary sodium (salt) on cardiovascular disease (CVD) has been debated for a long time. The present study aims to explore whether salt intake affects the risk of cardiovascular disease in the Chinese population. Data from a prospective cohort study that included 954 men and women aged 35-59 years at baseline from four urban and rural population samples in China were used. ⋯ However, this trend was not significant after adjusting for the baseline systolic blood pressure and antihypertensive medication use (P for trend = 0.171). No significant associations were found between sodium excretion and all-cause, cancer-related or other-cause mortality. High urinary sodium excretion was independently associated with an increased risk of cardiovascular disease in the general Chinese population.
