ABSTRACT
@#Introduction: Raised blood pressure is associated with diet high in sodium and low in potassium. According to the Malaysian Community Salt Survey (MyCoSS), Malaysian adults consume a high sodium diet, despite half claiming that they control their salt intake. The objective of this study was to investigate the association of sodium and potassium with salt-control claims among adults from the MyCoSS study based on 24-h urinary excretion. Methods: Data of 1,047 respondents aged 18 years and above who completed the knowledge, attitude, and practice (KAP) questionnaire were used in this study. Face-to-face interviews were conducted to acquire information on sociodemographic, medical reports and KAP on salt intake. Sodium and potassium level were assessed from 24-hr urine specimen, anthropometric measurements were done using WHO criteria, while blood pressure was measured using validated digital blood pressure monitor. Descriptive and analysis of variance (ANOVA) were used to determine the associations between urinary sodium and potassium with salt-control claims and practices. Results: The consumption of sodium was higher than recommended, while potassium was lower among respondents who claimed to control their salt intake. Significant associations were found between sodium intake with marital status, ethnicity, education level and employment status. Meanwhile, significant associations were found between potassium intake with ethnicity and employment status. Conclusion: Sodium intake was high, and potassium intake was low among respondents who claimed they control their salt intake. Further study with detailed intervention on specific target group is required to improve sodium and potassium intakes among Malaysian adults.
