Aim The rise in the prevalence of abdominal obesity (AO), in particular, has become a major concern as it contributes to diabetes, hypertension, high cholesterol, heart disease and certain types of cancer. The aim of this study is to determine the prevalence and associated factors of AO among older adults aged ≥60 years in Malaysia. Methods This was a nationwide cross-sectional study using two-stage stratified random sampling. In total, 3977 older adults aged ≥60 years were involved in this study. Socio-demography characteristics were obtained using self-administered questionnaire. AO was measured using waist circumference and classified according to the cut-off values of ≥90 cm for men and ≥80 cm for women based on the WHO recommendation. Descriptive and multiple logistic regression analysis using a complex sample design were performed for data analysis. Results Our findings showed that 2371 (67.3%) older adults had AO. Older adults who were from urban areas (69.7%), of women (78.4%), married (66.7%), with tertiary education (73.6%) and unemployed (70.9%) had the highest prevalence of AO. Those from urban areas (adjusted odds ratio [aOR] = 1.29), women (aOR = 3.12), unemployed (aOR = 1.14), diagnosed with hypertension (aOR = 1.56) and diabetes mellitus (aOR = 2.08) were also significantly associated with a higher risk of AO. Conclusions This study identified several risk factors that are associated with AO among older adults in Malaysia. Such information is important and needed to improve the healthcare system systematically, enable nutrition screening and appropriate intervention to combat the growing AO in Malaysia.
