To explore the relationship between dietary sodium intake and hypertension and provide scientific evidence on hypertension intervention, we used a subpopulation of 1,254 subjects aged 18–65 years old in Heilongjiang province from an ongoing longitudinal study, China Health and Nutrition Survey. We used a stratified multistage cluster sampling scheme to randomly select two cities and four counties in Heilongjiang province. Experienced physicians collected detailed diet data and measured blood pressures. The prevalence of hypertension increased from 25.0% in 2004 to 28.0% in 2009. Added salt intake decreased slightly from 7.6 g/day to 7.4 g/day; however this was offset by an increased sodium intake from 3.6 d/day to 3.8 g/day. One key change was the significant increase in processed food consumption from 60.5 g/day to 70.4 g/day. The increased prevalence of hypertension is much more rapid and has attained a much higher level in Heilongjiang than in other areas in China. Excessive intakes of sodium and processed foods, particularly pickled vegetables, may attribute to the high prevalence of hypertension. This study was supported by NIH (R01‐HD30880) and Fogarty International Center, NIH (5D43TW007709).
