Introduction: Polycystic ovarian syndrome (PCOS) is a highly prevalent endocrine abnormality affecting women in the age group of 15–45 years. Women with PCOS typically exhibit an androgenic pattern of body fat distribution, characterised by central adiposity, and are frequently accompanied by insulin resistance (IR) and elevated androgen levels. The homeostasis model assessment (HOMA-IR) has been used as a detection method of IR. Neck circumference (NC) is an easy method and can be accurately correlated with HOMA-IR. Methods: After obtaining ethical approval, data were collected from 143 diagnosed cases of PCOS patients. Anthropometric measurements—including height (cm), weight (kg), body mass index (BMI), waist circumference (WC), hip circumference (HC), and NC—were recorded using standardised tools. All data were entered into Microsoft Excel 2013 and analysed using SPSS version 21. Results: In the present study, 80 (55%) PCOS patients were diagnosed with IR based on the HOMA-IR cut-off of > 2.5. The levels of fasting blood glucose, fasting insulin, and anthropometric indexes (NC, WC, BMI, and waist-to-hip ratio WHR) in the IR group were much higher than those in the control group. There was a strong correlation of NC with anthropometric ratios like WC, WHR and BMI, whereas the correlation was moderate with HOMA-IR. Receiver operating characteristic analysis demonstrated that NC ≥ 30.75 cm had a high probability of being a marker of IR in women with PCOS. Conclusion: NC correlates significantly with BMI, WC, and WHR.
