Overweight and Obesity cause changes in Posture and biomechanics of lumbar spine function and weight transmission. Relationship between low back pain and Obesity requires study to learn about its causation and its effect. This study is an attempt in this direction by measuring the parameters of Body mass Index and its effects on Lumbosacral angles. Keywords: Low back pain; overweight; obesity; lumbosacral angles. 1. INTRODUCTION Overweight and obesity is a serious community health problem that contributes to the global trouble of chronic disease as a pandemic condition [1]. Hypertension, Diabetes and Obesity have been considered as predisposing factors to diseases like Gastro-oesophageal reflux, Obstructive sleep apnoea (OSA), certain types of cancers like breast cancer(post- menopausal), endometrial cancer, Gastro intestinal track related cancer etc [2]. Obesity causes changes in normal function and biomechanics of the vertebral column and big joints of limbs [3,4]. Study of curvature and angles of Lumbar and sacral spine helps to understand transmission of upper body weight to Study Protocol
