Occurrence of equine metabolic syndrome, clinical manifestations, and associated risk factors in Nigeria.
Abstract: Insulin dysregulation (ID) is central to the pathophysiology of equine metabolic syndrome (EMS), putting the horse at risk of laminitis. There is a paucity of information on the status of EMS in Nigeria. This study aimed to determine the occurrence of EMS, clinical manifestations, and associated risk factors in Nigeria. A cross-sectional study was carried out. Selected horses underwent an insulin 2-step response test to ascertain insulin dysregulation; a physical examination was carried out to diagnose laminitis and obesity. Risk factors were assessed using a questionnaire. The overall prevalence of EMS was 43.10%. Breed and sex were significantly associated with EMS, but age was not. Horses diagnosed with laminitis showed two signs of laminitis, namely, divergent hoof rings and widened white lines. Risk factors significantly associated with the prevalence of EMS were as follows: being a West African Barb horse (60.00%), being a stallion (67.86%), being a leisure horse (67.86%), only walking horses during exercise (68.00%), exercising horses once every 5 months (82.76%), tethering horses to a stake in the ground (67.86%), obesity (92.86%), and abnormal neck crest (83.33%). The risk of ID remains higher in obese horses. However, some of the horses with ID were not obese, indicating that there are other possible underlying causes of EMS.

The study investigates the prevalence, clinical signs, and risk factors of equine metabolic syndrome (EMS) among horses in Nigeria, highlighting the crucial role of insulin dysregulation in the condition and risk of laminitis.
Objective of the Study
- The research aims to explore the occurrence, clinical manifestations, and associated risk factors of equine metabolic syndrome (EMS) among horses in Nigeria, an area where information on the syndrome is scarce.
Methodology
- The study uses a cross-sectional design. Selected horses underwent an insulin two-step response test to determine insulin dysregulation, a key factor in EMS onset.
- Physical examinations were conducted to diagnose laminitis and obesity in the horses – two key clinical manifestations of EMS.
- Researchers also assessed certain risk factors using a questionnaire.
Findings
- The prevalence of EMS among the horse population in the study was found to be 43.10%.
- Breed and sex were significantly associated with EMS, while age was not.
- The study highlights certain physical characteristics typically found in horses with laminitis, an often-occurring condition in horses with EMS. These characteristics include divergent hoof rings and widened white lines.
- Main risk factors associated with a higher prevalence of EMS were: being a West African Barb horse, being a stallion, being a leisure horse, walking as the only form of exercise, exercising only once every five months, being tethered to a stake, obesity, and an abnormal neck crest.
- Obesity was found to be a significant risk factor; however, not all horses with insulin dysregulation were obese, suggesting other potential causal factors for EMS.
Conclusion
- The high prevalence of EMS among horses in Nigeria found in this study underscores the necessity of further research into this syndrome, particularly focusing on the role of insulin dysregulation and associated risk factors.
