In this study, we investigate the association between sodium intake and mortality in the Canadian adult population and estimate life expectancy in people consuming sodium below and above 2300 mg/day, known as the chronic disease risk reduction intake. We hypothesize that adults with sodium intake below the 2300 mg/day threshold have lower mortality rate and higher life expectancy than those with sodium intake above the threshold. We use the Canadian Community Health Survey Nutrition data linked to the Canadian Vital Statistics database using a probabilistic linkage performed by Statistics Canada. We estimate the usual dietary intake of sodium from 24-hour diet recalls using a method developed by the National Cancer Institute, known as the NCI method. We present our results investigating the association between usual sodium intake and mortality risk using a complementary log-log regression model with age and sex as confounders. We use the life table method to estimate life expectancy.
