Effects of waist-to-hip ratio on postoperative outcomes of lumbar degenerative diseases
Objective:To explore the effects of waist-to-hip ratio(WHR)on postoperative outcomes of lumbar degenerative diseases(LDDs).Methods:The medical records of 1220 patients with LDDs were retrospectively analyzed.The patients were divided into 3 groups according to the WHR,the ones with the WHR of＜0.85 in males and＜0.75 in females were assigned into the low WHR group(102 ca-ses),the ones with the WHR ranged from 0.85 to 0.9 in males,0.75 to 0.8 in females into the normal WHR group(705 cases),and the ones with the WHR of＞0.9 in males and＞0.8 in females into the high WHR group(413 cases).The operative time,intraoperative blood loss,Oswestry disability index(ODI)as well as the lower back,hip,leg and foot pain numeric rating scale(NRS)scores evaluated at postop-erative month 12 were compared among the 3 groups.Results:①There was statistical difference in the operative time and intraoperative blood loss among the 3 groups(118.8±25.6,125.5±18.8,139.3±26.6 minutes,F=11.238,P=0.001;125.4±20.6,140.9±28.6,188.2±31.6 mL,F=14.262,P=0.035).The operative time was longer,and the intraoperative blood loss was more in high WHR group compared to normal WHR group and low WHR group(P=0.001,P=0.001;P=0.001,P=0.001),while,the comparison of operative time and intraoperative blood loss between normal WHR group and low WHR group revealed no significant differences(P=0.136,P=0.117).②The difference was statistically significant in lower back,hip and leg pain NRS scores evaluated at postoperative month 12,while,not statistically significant in foot pain NRS score evaluated at postoperative month 12 among the 3 groups(2.60±0.96,2.17± 0.84,3.27±1.10 points,F=17.901,P=0.036;1.45±0.52,1.49±0.50,2.78±0.85 points,F=54.421,P=0.001;2.09±0.70,2.13±0.98,2.80±1.16 points,F=6.239,P=0.003;1.55±0.52,1.39±0.49,1.29±0.46 points,F=1.731,P=0.182).The lower back,hip and leg pain NRS scores evaluated at postoperative month 12 were higher in high WHR group compared to low WHR group and normal WHR group(P=0.045,P=0.001;P=0.047,P=0.003;P=0.029,P=0.001),while,the comparison between normal WHR group and low WHR group revealed no significant differences(P=0.176,P=0.291,P=0.716).③There was statistical difference in ODI evaluated at postoperative month 12 among the 3 groups(19.40±6.52,12.59±6.81,24.28±9.83％,F=30.502,P=0.001).The ODI evaluated at postoperative month 12 was higher in high WHR group compared to normal WHR group and low WHR group(P=0.001,P=0.042),and was higher in low WHR group compared to normal WHR group(P=0.019).Conclusion:A high WHR can increase the oper-ative time and intraoperative blood loss,and affect the postoperative pain relief and lumbar function recovery in patients with LDDs.
