Urinary sodium excretion is associated with increased body mass index: A cross-sectional analytical study among adults in Kuala Lumpur, Malaysia

The relationship between urinary sodium excretion and obesity is a critical area of research to understand the interactions among dietary sodium, weight gain, and the initiation of public health interventions to address obesity. This study aims to determine the association between urinary sodium excretion and body mass index (BMI). A cross-sectional study was conducted among 216 adults aged 18-65 years old who were recruited using convenience sampling in Kuala Lumpur, Malaysia. The overall mean urinary sodium was 274.00±127.57 mmol/L. Those with high levels of urinary sodium (T3) had significantly higher mean BMI (T3: 26.71±6.31 mmol/L; F=4.01, p=0.019). Age (F=6.24, p
