A total of 110 patients were enrolled and dividing into two groups; group A had obese females with LBP and group B had obese females without LBP Results: There was a significant relationship between body weight and LBP (p=0.039). There is a relation between diabetes mellitus and LBP (p=0.004). There was no significant relationship between height, sleeping time, nap hours, hypertension, rheumatoid arthritis, steroid use, asthma and smoking (p>0.05).
