STUDY DESIGN: Prospective follow-up study. OBJECTIVE: To investigate the influence of @entity28 and being overweight on disability and @entity158 of @entity1 undergoing lumbar spinal fusion. SUMMARY OF BACKGROUND DATA: Although spinal fusion surgery has been shown to relieve symptoms in several spinal disorders, the influence of @entity28 on the results remains controversial. METHODS: Since January 1, 2008, all @entity1 undergoing lumbar fusion in two hospitals have been invited to participate in a prospective follow-up database. At the end of 2014, the preoperative and 1-year follow-up data of 805 @entity1 were available. Disability was evaluated using the @entity717 Index and back and leg @entity158 by the visual analogue scale. In addition, the working status, smoking, physical activity, duration of symptoms, and indication for surgery were captured. According to the World Health Organization classification of preoperative body mass index, @entity1 were divided into three groups: normal weight (<25.0kg/m), overweight (25.0-29.9kg/m), and @entity28 (>= 30.0kg/m). RESULTS: Of the 805 @entity1 , 204 (25.3%) were normal weight, 365 (45.3%) were overweight, and 236 (29.3%) were @entity28 . The @entity1 in the @entity28 group exercised significantly less per week (P<0.001). Preoperatively, the body mass index groups did not differ with regard to disability and @entity158 . At the 1-year follow-up, the change in the @entity717 Index was -25 in normal, -24 in overweight, and -23 in @entity28 @entity1 (P=0.013), and disability was severe in 14.7% of the normal group, 17.0% of the overweight group, and 24.2% of the @entity28 group (P=0.0052). Back and leg @entity158 improved more in the normal weight group compared with the overweight or @entity28 groups (P<0.05). CONCLUSION: Although lumbar spine fusion is also effective in @entity28 @entity1 , the present large follow-up study demonstrates that their outcome results are slightly poorer than @entity1 with normal weight at 1 year after surgery. LEVEL OF EVIDENCE: 3.
