Abstract P094: Determinants of Salt Consumption in Rural Bangladesh: Findings from Assessment of 24 H Urinary Sodium Excretions
Introduction: Cardiovascular diseases (CVDs) are the leading cause of death among adults and their prevalence has been increasing in the developing countries such as Bangladesh. Evidence from randomized controlled trials demonstrated that higher sodium intake increased blood pressure and the risk of hypertension. However, levels of sodium intake and determinants of sodium intake have not been assessed in Bangladeshi population before.
Objective: The objective of the study was to assess the levels and determinants of salt consumption in rural Bangladesh which would be useful for future interventions related to hypertension risk reduction.
Method: Data were collected in three selected villages (representing hilly, coastal and plain) of Chakaria upazilla, Cox’s Bazaar district, Bangladesh from October to November, 2011.We collected information on socio demographic variables and behavioural variables related to salt consumption. We used 24 hour urinary sodium excretion method for measuring individual salt consumption. Information was collected from randomly selected 396 adults above 20 years of age. The data were analyzed using both univariate analysis and linear regression.
Results: The mean level of salt consumption in this population was 6.92 grams/d. In linear regression women (95% CI: 0.236, 2.140) and those with some education (95% CI: 0.177, 2.147) were significantly more likely to have higher levels of salt consumption compared to males and those without education. Household wealth was negatively associated (95% CI:-0.839,-0.175) with salt consumption which means that individuals from poorer households had significantly higher salt consumption compared to those from richer households. In rural Chakaria most of the salt was consumed from foods cooked at home unlike developed countries. During the survey 26% individuals reported using additional salt during meals and 78% people said that they add salt to fresh fruits.
Conclusion: The mean salt consumption in rural Bangladesh is slightly higher than recommended. However, as most of the salt is consumed from foods cooked at home sodium replacement strategies may have to be considered. If salt reduction strategies are designed for this population is important to understand and address increased salt consumption of women, poor and people with some education in the community in rural Bangladesh.
