Abstract: Background
High dietary salt intake is a recognized contributor to hypertension and cardiovascular
diseases, particularly in low- and middle-income countries. Despite the high burden
of hypertension in Nepal, robust estimates of salt intake using the gold standard 24-
hour urinary sodium collection remain scarce, especially in suburban populations.
Objective
To accurately assess dietary salt intake using 24-hour urinary sodium excretion and
evaluate factors influencing salt consumption in a suburban Nepali population.
Method
A cross-sectional study was conducted in 2023-2024 as part of the Dhulikhel Heart
Study’s second phase. A total of 381 adult participants were recruited from randomly
selected wards of Dhulikhel Municipality. Data on sociodemographic characteristics,
dietary habits, salt-related knowledge, and anthropometry were collected. Salt
intake was estimated from 24-hour urinary sodium excretion. Generalized Estimating
Equations (GEE) and multivariate analyses were used to identify associated factors.
Result
The mean age of the participants was 49.9 ± 15.5 years and average salt consumption
was 9.55 ± 3.2 g/day. The mean dietary salt intake significantly exceeded WHO
recommendations, with notable variations by sex, education, and frequency of
eating out.
Conclusion
This study highlights alarmingly high salt intake in a suburban Nepali community
and underscores the need for population-specific strategies to reduce sodium
consumption. Policy action, public education, and promotion of healthier dietary
behaviors are essential to combat the growing burden of salt-related noncommunicable
diseases.
