Abstract: Childhood Obesity, previously a feature of the industrialized nations is now prevalent in the developing countries. The grim health index and the poor condition of the Nigerian built environment which is unable to tackle the epidemic were examined. This study explores how the physical environment at home, in the neighborhood and at school can help promote physical activity and thus prevent obesity. Infrastructure planning is presented as a strategy of increasing the level of physical activity among children. With generous support from educational managers, physical planners, politicians and policy makers, it is believed that a positive index would emerge.
