Estimation of Salt Consumption from 24-hour Urine Collection in a Nepalese Population (P18-084-19)

Abstract

ObjectivesHigh salt (sodium chloride) intake is associated with an increased risk of hypertension, which is a major risk factor for cardiovascular diseases. Current consumption of salt in Nepal is unknown. The objective of this study was to estimate average salt intake in a Nepalese population from 24-hr urine collection in a population-based survey. MethodsParticipants (n = 499) were recruited from the Community-Based Management of Non-Communicable Diseases in Nepal (COBIN) cohort in the peri-urban area of Pokhara municipality from July to December 2018. The modified version of STEPS survey of non-communicable diseases (NCD) risk factors was administered. Salt intake was estimated from a single 24-hr urine collection. Multivariate linear regression was used to estimate differences in salt intake (g) associated with a variety of factors including demographics, lifestyle, health care, and health literacy. ResultsMean (SD) age was 50.0 (9.7) years; mean salt intake was 13.0 (4.8) g/person/d. Male gender, younger age, and higher body mass index were significantly associated with higher salt intake (Table). Although 55% of respondents thought that they consumed just the right amount of salt, 96% were consuming more than the WHO-recommended level of less than 5 g/d. Almost half of the respondents reported that they consumed processed food containing high amounts of salt. In multivariate analyses, systolic blood pressure was 0.4 mmHg (95% CI: 0.05, 0.7) higher per 1-gram increase in salt intake. ConclusionsDaily intake of salt in this Napalese population was over twice the WHO recommended upper limit, indicating a substantial need to reduce salt across the entire population. Community-based interventions for behavior modification through health education and dietary counseling may be effective in this population where salt is added during cooking. Still, interventions targeting the marketing, availability, and labeling of processed foods is also important, as intake of processed foods was also commonplace in Nepal.
