The effect of sex and obesity on the lumbar lordosis

Background and Objective: The curves of vertebral column have an important role to shock absorption and stability of the spine. The goal of this study was to evaluate the correlation between total and segmental lumbar lordosis with sex and obesity. Methods: One hundred volunteers (54 males and 46 females) aged between 20-70 years and without a history of low back pain were selected. A standing lateral radiograph of the lumbar spine was taken for each volunteer. Then by using Cobb methods, the total and segmental lumbar lordosis was measured from radiographic film. The age, sex, height and weight of each participant were recorded and also BMI for each participant were calculated. Data were statistically analyzed and the difference between points were considered significant at P
