%X Goal: To study the interaction of obesity and age in patients with multiple spine surgeries. Methods: Data on the body mass index (BMI) of 956 patients were collected and classified into four groups: non-obese (BMI <30 kg/m2), obese-class I (BMI ¡Ý30 kg/m2), obese-class II (BMI ¡Ý35 kg/m2) and obese-class III (BMI ¡Ý40 kg/m2). Patients' age was categorized into the following age groups: ¡Ü40, 41¨C65 and ¡Ý66. T-test and Chi-square test were applied using SPSS v16. Results: In lumbar patients aged ¡Ý66 years with previous spine surgery, the average number of previous spine surgeries significantly increased with increasing obesity from 1.4 in nonobese patients to 1.7, 2.5 and 3.5 in obese class I, II and III patients.In lumbar decompression and fusion patients aged ¡Ý66 years with previous spine surgery, the average number of previous spine surgeries signifi-cantly increased with increasing obesity from 1.7 in nonobese patients to 1.6, 2.0 and 3.5 in obese class I, II and III patients. A similar trend was noted in lumbar microdiskectomy patients aged ¡Ý66 years but it was statistically nonsignificant due probably to small numbers. Conclusion: Obesity is associated with an increased number of previous spine surgeries in patients over 65 years of age undergoing lumbar surgery.
