Comparison of three spot urine formulae and their validation using 24-hour urine sodium for estimation of daily salt intake: a cross-sectional study among Bangladeshi adults

ABSTRACT:

Objective

This study aimed to assess the validity of three commonly used (Tanaka, Kawasaki, INTERSALT) methods based on spot urinary sodium excretion against the 24-hour urinary sodium excretion to estimate the dietary salt intake in Bangladesh.

Design

A population-based cross-sectional survey.

Setting

A cross-sectional survey was done in an urban and a rural area of Bangladesh in 2012–2013.

Participants

418 community living residents aged 40–59 years participated in the survey and data of 227 subjects who had complete information were analysed for this validation study.

Outcome measures

The Bland-Altman method was used to evaluate the agreement between the estimated and measured 24-hour urinary sodium. The estimated average salt intake from Tan
