Abstract Background Plasma concentrations of Acylation stimulating protein (ASP) and Orexin-A are closely linked to body weight and energy homeostasis. The purpose of this study is to describe the associations of A:O with metabolic risk marker in women. Methods This is a case control study. Total 382 women were recruited for the study.192 women with metabolic syndrome (WmetS) &190 women without metabolic syndrome (WometS) according to NCEP-ATPIII guidelines. Serum ASP and Orexin-A level were determined by enzyme linked immunosorbent assay. Results Result indicated that Waist Circumference, Blood pressure, Lipid profile, Glucose (FPG), Insulin resistance (HOMA-IR), ASP and A:O ratio were significantly higher but HDL and Orexin-A level were significantly lower in WmetS than WometS. The correlation of ASP, A:O ratio were positively significant correlated with Waist Circumference (WC), Triglyceride (TG), Glucose (FPG) and negatively significant correlated with High density lipoprotein (HDL), however the orexin-A was negatively significant correlated with WC and TG in WmetS. Conclusion The study concluded that A:O ratio may be one of the potential biomarker for metabolic syndrome.
