Background. Abdominal obesity (AO) is a medical problem in which excess fat has accumulated in the abdomen to the extent that it may have an adverse effect on health and/or increase medical problems. AO is associated with mortality morbidity, increased disability, poor quality of life and increased health care costs. Objective: The objective of this study is to assess the magnitude of central obesity and associated factors among adults in Addis Ababa, Ethiopia from February to March, 2020. Methods: A cross sectional community based study was employed on adults 18-64 in Addis Ababa. Data has been collected by using interviewer administered questionnaire consisting Food frequency questions, Dietary diversity score and assessment of physical activities and anthropometric measurements. Data entry, coding, editing and cleaning was done by using SPSS for windows version 25. Descriptive statistics and binary and multiple logistic regression were done to describe the data and isolate independent predictors of central obesity. Crude and adjusted odds ratios were used to ascertain any associations between the dependent and independent variables while 95% confidence intervals and P<0.05 was used to declare statistical significance. Results: The prevalence of central obesity was 33.4%, which is 41.39% (95% CI: .36-.46) for females and 25.7% (95% CI: .21-.29) for males. On the multivariable logistic regression model after adjusting for other variables age above 55 [AOR=7.23(4.70-6.17)] female [AOR = 2.82(95%CI: 1.30-3.79)], high dietary diversity [AOR = 0.61(95%CI: 0.28-0.48)], alcohol consumption [AOR = 2.18(95%CI: 1.22-3.89)], , and high wealth index [AOR = 9.69(95%CI: 4.25-22.06)] and physical inactivity [AOR = 3.10(95%CI: 2.90-4.88)], were significantly associated with central obesity. Conclusion and Recommendation: The result revealed high prevalence of central obesity among adults of Addis Ababa. Central obesity was higher among those in age group between 55-64 years, in females, in those with low level of education, low diversified diet eaters, alcohol consumers, in the high wealth group and among physically inactive individuals. The result imply need for promotion of having regular physical activity, eating diversified diet, limiting alcohol drinking and low energy foods were recommended to prevent central obesity and associated risks.
