Introduction: This study examined how waist circumference (WC) varied across sociodemographic characteristics of Malaysian adults using a nationally representative data. Methods: Data from the Malaysian Adult Nutrition Survey 2014 (n = 2696) was used. In the sample, 46.55% were males and 53.45% were females. The outcome variable was WC. Waist circumference was categorised into four ordinal outcomes: very low, low, high and very high. The ex- planatory variables were age, monthly individual income, education, gender, marital status, ethnicity, employment status and household location. Ordered probit models were utilised. Results: The majority of males had a low WC (54.66%), and only a small proportion had a very high WC (0.96%). Similarly, a high proportion of females had a low WC (55.59%), and only 1.94% had a very high WC. Younger males were more likely to have a high WC than their older counterparts. Males who had monthly income of RM2000-2999 or RM3000-3999 were more likely to have a high WC compared with those who had monthly income of RM999. Chinese and Indian males were more likely to have a high WC than Bumiputera males. For females, those who were married, widowed/divorced and Bu- miputera were likely to have a high WC. Conclusion: WC was associated with various sociodemographic profiles of males and females. In particular, there were positive associations between the likelihoods of having a high WC and younger age group, higher income, Chinese, Indian, and being married. Our findings provided policy makers with better information on formulating intervention measures.
