Background: Genu varum (bow leg) is a deformity of the knee marked by medial angulations of the leg in relation to the thigh, an outward bowing of the legs, giving the appearance of a bow. This study was carried out to determine the prevalence of genu varum among children between 6-10 years old in some Urhobo communities in Delta state, Southern Nigeria. Materials and Methods: The study populations were drawn by purposive sampling from Ughelli, Warri, and Sapele. Data were collected on 1000 children (500 males and 500 females). Physical examination of the children was carried out by measuring their medial intercondylar distances by using calipers and meter rule while the children stood erect with their ankles touching. Children with medial intercondylar distances greater than 0.2cm (the mean value for normal Nigeria children) demonstrates the deformity (genu varum) and the frequency, age. sex was recorded. Results and Discussions: Based on this data, 43 in 1000 volunteers had genu varum. It was also seen that the prevalence was highest in 6 years old age group and lowest in 10 years old age group. It was noted as the ages increase, the prevalence rates among the age groups decreases. The prevalence of this deformity in Urhobo communities is low when compared with the overall prevalence in Nigeria. The Urhobos live in the riverine area of Southern Nigeria and their occupation are mainly farming, hunting and fishing. Their meals consists mainly of products from the farm, hunting and sea foods which are very rich in protein/calcium. Children in Urhobo Communities are also well exposed to sunlight. Conclusion: The prevalence of this genu varum in this ethnic nationality although low can be further reduced with enlightenment and education of parents and children on the importance of balanced diet.
