Abstract

OBJECTIVE To investigate the associations of sodium excretion with blood pressure, mortality and cardiovascular diseases in Chinese population. METHODS We studied 39 366 individuals aged 35-70 years from 115 urban and rural communities in 12 centers across mainland China. Trained research staff conducted face-to-face interview to record baseline information of all participants based on questionnaires, and collected their morning fasting urine samples to estimate 24-h sodium excretion (24hUNaE). Multivariable frailty Cox regression accounting for clustering by centre was performed to examine the association between estimated 24hUNaE and the primary composite outcome of death and major cardiovascular events in a Chinese population. RESULTS Mean 24hUNaE was 5.68 (SD 1.69) g/day. After a median follow-up of 8.8 years, the composite outcome occurred in 3080 (7.8%) participants, of which 1426 (3.5%) died and 2192 (5.4%) suffered from cardiovascular events. 24hUNaE was positively associated with increased SBP and DBP. Using the 24hUNaE level of 4-4.99 g/day as the reference group, a 24hUNaE of either lower (
