Prevalence of Liver Steatosis Among Workers in Ouagadougou and Associated Factors: A Cross-Sectional Study.

AIMS

Liver steatosis prevalence is growing, linked to the current worldwide epidemics of obesity and Type 2 diabetes. In sub-Saharan Africa, data on apparent healthy workers must still be included. This study aimed to determine the prevalence of hepatic steatosis and its associated factors in the workplace.

METHODS AND RESULTS

A cross-sectional study was conducted from July to October 2022 in seven selected public and private works places in Ouagadougou, Burkina Faso. Workers still in activity were enrolled by random sampling. Sociodemographic and anthropometric characteristics and blood pressure measurements were performed using standard procedures. Blood samples for fasting blood glucose, cholesterol (total, HDL, LDL), triglycerides, transaminases (AST, ALT), gamma-glutamyl-transferase, C reactive protein, uric acid, surface antigen of hepatitis B (HBsAg), antibody to hepatitis C virus (anti-HCV), and HIV antibodies have been realized. Liver steatosis was assessed by FIBROSCAN with controlled attenuation parameter (CAP). An adjusted logistic regression analysis was performed. A significance level of 5% was applied. A total of 500 workers were included in this study. Among them, 293 (58.6%) were men. The prevalence of hepatic steatosis was 18% (95% CI: 14.7-21.7). Factors associated with hepatic steatosis were age over 50 ( = 0.038), waist circumference ( = 0.0001), body mass index ( = 0.008), and cytolysis ( = 0.001).

CONCLUSION

Liver steatosis affects almost a fifth of working people. Health policies must step up the fight against obesity and other nutrition-related noncommunicable diseases.
