Background: Accurate anthropometric measurements are essential in clinical practice, sports science, and epidemiological research. However, their reliability may be influenced by methodological and sociocultural factors. This study examined intra and interrater reproducibility of anthropometric measurements, with emphasis on genderrelated influences among undergraduate students at Ebonyi State University, Abakaliki. Methods: Ninetysix students aged 18–30 years were assessed using standardized ISAK protocols. Parameters included height, weight, head girth, neck girth, arm girth (relaxed and flexed), forearm girth, waist circumference, and gluteal girth. Two trained raters (one male, one female) independently measured both male and female participants to evaluate samegender and crossgender reproducibility. Reliability was analyzed using Intraclass Correlation Coefficient (ICC), Bland–Altman plots, Cronbach’s Alpha, and correlation coefficients. Ethical approval was obtained, and informed consent ensured voluntary participation and confidentiality. Results: Height and weight demonstrated excellent reproducibility across all groups (ICC 0.99). In contrast, circumferencebased parameters, particularly waist and gluteal girth, showed weaker agreement in crossgender assessments (male gluteal girth ICC = 0.426; female gluteal girth ICC = 0.291). Samegender measurements consistently yielded higher reliability, while oppositegender measurements introduced greater variability, especially in culturally sensitive body regions. Conclusion: While measurement errors cannot be fully eliminated, adherence to standardized protocols and incorporation of gender sensitive approaches significantly enhance accuracy and reproducibility in anthropometric research.
