Core Tip
Core Tip: Our case-control study revealed that the risk of perianal abscesses (PAs) was significantly correlated with various obesity/metabolic markers, including higher body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio, glucose levels, uric acid levels, cholesterol levels, triglyceride levels, and low-density lipoprotein (LDL) cholesterol levels, as well as lower levels of high-density lipoprotein cholesterol. The mendelian randomization analysis further confirmed relationships between the PA risk and factors such as BMI, WHR, large and medium LDLs, and lipid ratios. These findings suggest that lipid levels, body fat distribution, and metabolic markers are crucial to the understanding of PA risk.
