Health Education programme provides needed preparation of students which should build their personal competence towards avoidance of body mass index (BMI) problems. Therefore, the study compared university students with different health education achievements by mean BMI and determined if the achievements, gender, age range, and class level have significant interactions on mean BMI of the students. Descriptive survey was used and from 222, a sample of 87 Health Education students were purposively selected in the Department of Health, Safety and Environmental Education, University of Benin. A ‘BMI Scale’, a Xiaomi Mi Smart Scale 2 (Model: XMTZC04HM), a standardized measuring tape and the 2022/2023 Senate Approved 100, 200, 300 and 400 Levels Health Education Programme Results were used to collect data. Data were analysed with descriptive and inferential statistics. Results showed that the BMI of university students with different Health Education achievements is possible normal weight with majority of the participants (54.0%), with the possible normal weight having a GPA of 2.40 – 3.49 while the least number of them (4.6%), had a GPA of 4.50 – 5.00. However, different Health Education achievements, gender, age range and class level had no interactions on mean BMI of the students at 0.05 level of significance. Therefore, Health Education students should be encouraged by their lecturers to continuously apply knowledge of Health Education into healthy behaviours appropriate to maintain possible normal weight.
