Background: Metabolic syndrome has always been linked with obesity and a sedentary lifestyle due to induction of metabolic derangements. Orexin A and B are recently discovered hypothalamic neuropeptides. Orexin A regulates appetite, food intake, and energy expenditure.
Aims and Objectives: Metabolic fuel detectors regulate energy balance at peripheral and central levels. The aim of this study is to assess association of serum orexin levels with metabolic risk markers in women of reproductive age group (RAG).
Materials and Methods: The study was conducted in the campus of King George Medical University (KGMU), Uttar Pradesh, Lucknow, INDIA. One hundred and fifty apparently healthy women of RAG, that is, 20–40 years of age were randomly selected. Fasting serum orexin and serum insulin levels were measured using enzyme-linked immunosorbent assay and weight, body mass index (BMI), fasting blood glucose, lipid profile, and blood pressure were estimated in women.
Results: The results show that serum orexin levels have significant positive correlation with fasting blood glucose, weight, BMI, and waist circumference along with a weak negative correlation with serum insulin level.
Conclusion: In the present study, serum orexin levels significantly correlate with weight, BMI, fasting blood glucose, and weak negative correlation with serum insulin levels. Serum orexin levels did not correlate with the lipid profile of women of RAG.
