Dietary sodium intake in urban and rural Malawi, and directions for future interventions.

ABSTRACT:

Background

High dietary sodium intake is a major risk factor for hypertension. Data on population sodium intake are scanty in sub-Saharan Africa, despite a high hypertension prevalence in most countries.

Objective

We aimed to determine daily sodium intake in urban and rural communities in Malawi.

Design
