Sociodemographic correlates of knowledge about high sodium-related diseases among adults in Malaysia

The prevalence of high sodium-related diseases is increasing across the globe. Knowledge plays an important role in disease prevention. The objective of the present study was to examine sociodemographic factors associated with knowledge of high sodium-related diseases. The Malaysian Community Salt Survey (MyCoSS) was used in the present study for secondary analyses. It is a nationwide cross-sectional survey that was conducted in Malaysia. A non-parametric test to evaluate trends and a negative binomial regression were utilised to assess knowledge of high sodium-related diseases. Income, educational level, gender, ethnicity, house locality and hypertension were found to be significantly associated with knowledge of high sodium-related diseases. In particular, higher income earners, well-educated people, women, Malays, urban dwellers and hypertensive adults were more likely to have acquired a lot of knowledge of high sodium-related diseases compared to that acquired by lower income earners, less-educated people, men, individuals of other ethnic groups, rural dwellers and nonhypertensive adults. In conclusion, sociodemographic factors and hypertension play an important role in knowledge acquired about high sodium-related diseases. The findings of the present study could inform a future policy directed towards increasing knowledge about high sodium-related diseases among the population in Malaysia.
