Background: Body Mass Index (BMI) is a simple and widely used indicator of weight status, but its interpretation and accuracy are often influenced by individual perception and educational level, particularly in diverse populations such as the Ekpeye ethnic group in Rivers State, Nigeria. Aims: To determine the mean Body Mass Index (BMI), examine sexual dimorphism, and evaluate the influence of educational level on BMI and its perception among the Ekpeye ethnic group in Rivers State, aged 18–45 years. Study Design: A cross-sectional study carried out on the Ekpeye ethnic group in Rivers State, between the ages of 18 and 45 years. Place and Duration of Study: The research was conducted across three communities within the Ekpeye Kingdom, namely: Ubeta, Ahoada, and Ihike of Rivers State, Nigeria. Methodology: A total of 500 subjects (250 males, 250 females) participated. Materials used included a weighing scale for weight, a meter rule for height, and a structured questionnaire. Data were analyzed for mean, standard deviation, BMI categories, perception accuracy, and correlations. Results: Mean values for males: weight 61.72±9.15kg, height 1.67±0.07m, BMI 22.02±3.07kg/m². For females: weight 61.82±10.61kg, height 1.61±0.06m, BMI 23.87±3.87kg/m². No significant difference in weight between sexes (p>0.05); males were significantly taller (p<0.05); females had significantly higher BMI (p<0.05). BMI distribution: females – 4% underweight, 65% normal, 24% overweight, 7% obese; males – 9% underweight, 77% normal, 11% overweight, 3% obese. Most normal-weight individuals had a secondary/tertiary education. Incorrect BMI perception: 70% of obese females, 57% of obese males. Strong positive correlation between BMI and body weight (p<0.05). Conclusion: The study provides valuable anthropometric data and highlights the role of education in BMI awareness. Findings are useful for anatomists, neuroscientists, and clinicians.
