Background
Obesity and overweight are known are public health scourge challenges affecting populations across the world. These conditions have been associated with a wide range of chronic diseases including type 2 diabetes mellitus, cardiovascular disease, and cancers. In Ethiopia, literature regarding the burden of central (abdominal) obesity is scarce. This study aimed to fill this gap by assessing the prevalence and risk factors associated with central obesity among adults in Ethiopia.
Methods
From May to July 2021, a community-based cross-sectional survey was conducted on a sample of 694 adults aged >=18 years in administrative towns of Bale zone, Southeast Ethiopia. Multi-stage sampling followed by systematic random sampling was employed to identify study participants. Waist and hip circumferences were measured using standard protocols. The World Health Organization STEPS wise tool was used to assess risk factors associated with central obesity. Bi-variable and multi-variable binary logistic regression were used to identify factors associated with central obesity. Adjusted odds ratios (AOR) and their corresponding 95% confidence intervals (CI) were reported to estimate the strength of associations.
Results
The overall prevalence of central obesity using waist circumference was 39.01% (15.44% for men and 53.12% for women). Multi-variable binary logistic regression analysis revealed that female sex (AOR=12.93, 95% CI: 6.74-24.79), Age groups: 30-39 years old (AOR=2.8, 95% CI: 1.59-4.94), 40-49 years (AOR=7.66, 95% CI: 3.87-15.15), 50-59 years (AOR=4.65, 95% CI: 2.19-9.89), >=60 years (AOR=12.67, 95% CI: 5.46-29.39), occupational status like: housewives (AOR=5.21, 95% CI: 1.85-14.62), self-employed workers (AOR=4.63, 95% CI: 1.62-13.24), government/private/non-government employees (AOR=4.68, 95% CI: 1.47-14.88) and skipping breakfast (AOR=0.46, 95% CI: 0.23-0.9) were significantly associated with central obesity.
Conclusions
Abdominal obesity has become an epidemic in towns of southeast Ethiopia, and the prevalence is higher among women. Female sex, older age group, being employed, not skipping breakfast were significantly associated with central obesity.
