摘要目的:探讨肥胖绝经后女性脂肪分布与股骨颈强度综合指数相关性。方法:选取非低体重绝经后女性293例，完善实验室检查、人体成分分析仪以及双能X线骨吸收仪检查，根据体重指数(body mass index, BMI)将研究对象分为正常BMI组(18.5 kg/m 2≤BMI<24.0 kg/m 2, 91例)、超重组(24.0 kg/m 2≤BMI<28.0 kg/m 2, 115例)和肥胖组(BMI≥28.0 kg/m 2, 87例)，并对测量结果进行分析研究。 结果:绝经后女性肥胖组所有部位骨密度(bone mineral density, BMD)均高于正常BMI组和超重组( P<0.005)，肥胖组压缩强度指数(compression strength index, CSI)，弯曲强度指数(bending strength index, BSI)和冲击强度指数(impact strength index, ISI)均显著低于正常BMI组( P<0.001, P＝0.008, P＝0.001)。肥胖组中腰围、腰臀比、总脂肪量、四肢脂肪量、躯干脂肪量是CSI、BSI和ISI独立于年龄、空腹血糖、BMI的危险因素( P<0.05)。内脏脂肪等级与中国内脏脂肪指数是LSI、BSI和ISI的危险因素( P<0.05)。 结论:绝经后肥胖女性股骨颈强度综合指数降低，此人群皮下脂肪与内脏脂肪均与股骨颈强度综合指数负相关。

abstractsObjective:To investigate the correlation between fat distribution and the composite indices of femoral neck strength in obese postmenopausal women.Methods:A total of 293 postmenopausal women with non-low body weight were selected, laboratory tests, body composition analyzer test and double-energy X-ray absorptiometry scan were performed. Based on the body mass index(BMI), they were divided into three groups, the normal BMI group(18.5 kg/m 2≤BMI<24.0 kg/m 2, n=91), the overweight group(24.0 kg/m 2≤BMI<28.0 kg/m 2, n=115), and the obese group(BMI≥28.0 kg/m 2, n=87). The measurement results were analyzed. Results:In the obese group, bone mineral density(BMD) of all sites was higher than that in the normal BMI group and overweight group( P<0.005), compression strength index(CSI), bending strength index(BSI), and impact strength index(ISI) were significantly lower than those in the normal BMI group( P<0.001, P=0.008, P=0.001). In the obese group, waist circumference, waist-hip ratio, total fat mass, appendicular fat mass, and trunk fat mass were risk factors for CSI, BSI and ISI independent of age, fasting blood glucose, and BMI( P<0.05). Visceral fat grade and Chinese visceral adiposity fat index were the risk factors for CSI, BSI, and ISI( P<0.05). Conclusion:The composite indices of femoral neck strength decreased in obese postmenopausal women, and both subcutaneous fat and visceral fat were negatively associated with the composite indices of femoral neck strength.
