Study summary

Increasing sodium intake raises blood pressure. And high salt intake could hinder the management of chronic disease. Much previous research has confirmed that dietary habits are affected by economic status. So we compared sodium intake with economic status. We investigated the prevalence, extent and management, and the relevance of sodium intake with income level.
