Impact of a community-based lifestyle intervention program on blood pressure and salt intake of normotensive adult population in a developing country

BACKGROUND: Data on the effect of lifestyle intervention programs on salt intake and blood pressure in developing countries are scarce. This study aimed to assess the impact of a healthy lifestyle community-based trial on salt intake and blood pressure among a representative sample of normotensive I...

description BACKGROUND: Data on the effect of lifestyle intervention programs on salt intake and blood pressure in developing countries are scarce. This study aimed to assess the impact of a healthy lifestyle community-based trial on salt intake and blood pressure among a representative sample of normotensive Iranian adults. MATERIALS AND METHODS: We compared the data for salt intake, urinary sodium levels and blood pressure from three cross-sectional surveys in time points of 1999, 2001-2002 (beginning of the community interventions), and 2007 (after the community trial) for normotensive adult population of Isfahan, Iran in the framework of Isfahan Healthy Heart Program. Using multi-stage cluster sampling method, one of the family members at each household was randomly selected with Iranian adult population as a target. Dietary salt intake was estimated based on 24 hour urinary sodium levels. Systolic and diastolic blood pressures were measured according to standard methods. RESULTS: Dietary sodium intake and urinary sodium levels as well as systolic and diastolic blood pressure were significantly decreased during the 9-year study period. Unlike systolic and diastolic blood pressures that had a consistent decrement between 1999 and 2007, dietary sodium intake and urinary sodium levels were slightly raised from 1999 to 2000-2001 and then reduced between 2001-2 and 2007 evaluations. The same findings were reached when data were analyzed separately by gender or weight status. CONCLUSIONS: A lifestyle community trial was effective in controlling the escalating trend of blood pressure and salt intake in Iranian population. It can be considered as a model to be adopted in other developing countries.
