Background: Evidence suggests that the middle and low-income countries such as Ethiopia are facing the growing epidemic of both communicable and non-communicable diseases creating burden on the healthcare system. The increasing prevalence is attributed to sedentarism, lifestyle changes and the presence of other cardio-metabolic risk factors. Therefore this study was designed to assess the prevalence and association of overweight, obesity, and cardio metabolic risks and to explore if there was any agreement among the anthropometric measurements among the academic employees of the University of Gondar, Ethiopia.
Methods: An institutional based cross-sectional study was conducted using the WHO stepwise approach and recommendations on 381 academic staff of the university. In addition, physical measurements such as weight, height, waist and hip circumferences, and biochemical measures such as blood pressure and fasting blood glucose level (peripheral blood samples by finger puncture) were measured using standardized tools.
Result: The mean age of the participants was 33.5 years. The prevalence of obesity among the study participants defined by body mass index, waist circumference, waist height ratio and waist hip ratio was 13.1%, 33.6%, 51.9% and 58.5% respectively. The prevalence of diabetes was 4.7% among which 1.3% was not diagnosed prior to this study. About 53 (13.9%) of the study sample were found to be hypertensive (6.3% known versus 29 7.6% newly diagnosed). Among the participants 39.4% and 23.4% were found to be pre hypertensive and pre diabetic respectively. WC was significantly associated with HTN (AOR = 5.14; 2.50, 9.72), pre-DM (AOR = 4.03; 2.974, 5.96), DM (AOR = 3.29; 1.09, 6.01). In addition, WHtR was significantly associated with Pre-HTN (AOR = 2.69; 1.49, 4.58), HTN (AOR = 2.06; 1.01, 6.31), and DM (AOR = 1.85; .76, 4.32).
Conclusion: This study results revealed the variable prevalence between general obesity and the anthropometric indices (IDF cutoff) defining central obesity; WC, WHtR, and WHR among the participants. The result of this study suggests that the constructs of central obesity, not BMI has to be used to screen risks of cardio-metabolic risks among Ethiopians.
