【摘要】：目的通过分析腰椎骨髓脂肪含量与年龄、性别、体重指数(BMI)及腰围的相关性,探讨骨髓脂肪含量的体质特点,以加深对骨质疏松发生规律的认识。资料与方法纳入健康志愿者或慢性腰腿痛患者144例,测量其身高、体重、腰围,并计算BMI。采用单体素点分辨波谱法对L3椎体进行波谱采集,以1.3 ppm波峰为三酰甘油峰,水峰位于4.67 ppm,计算脂水比与脂肪比例。比较不同性别、年龄、BMI、腰围组间L3椎体脂水比、脂肪比例的差异。分析年龄与L3椎体脂水比及脂肪比例的相关性。结果男、女L3椎体脂水比、脂肪比例总平均值比较差异无统计学意义(t=-0.267、-0.993,P0.05)。不同年龄段患者L3椎体脂水比、脂肪比例的总平均值差异有统计学意义(F=3.723、5.478,P0.05)。女性61~70岁组L3椎体脂水比、脂肪比例均明显高于20~30岁、31~40岁、41~50岁、51~60岁组(P0.05),女性L3椎体脂肪比例20~30岁组低于70岁组(P0.05)。61~70岁组男女脂水比总平均值均明显高于20~30岁、31~40岁、41~50岁、51~60岁组(P0.05)。20~30岁组男女脂肪比例总平均值均低于31~40岁、41~50岁、51~60岁、61~70岁、70岁组(P0.05),61~70岁组与31~40岁、41~50岁、51~60岁组比较,差异均有统计学意义(P0.05)。不同BMI及男性和女性不同腰围组间L3椎体脂水比及脂肪比例比较,差异均无统计学意义(P0.05)。年龄与L3椎体脂肪比例呈正相关(r=0.321,P0.05)。结论腰椎骨质脂肪含量与患者年龄相关,与性别、BMI、腰围均无关。
[Abstract]:Objective to explore the physique characteristics of bone marrow fat content by analyzing the correlation between bone marrow fat content of lumbar vertebrae and age, sex, body mass index (BMI) and waist circumference, so as to understand the regularity of osteoporosis. Materials and methods the height, weight and waist circumference of 144 healthy volunteers or patients with chronic low back leg pain were measured and BMIs were calculated. The L3 vertebrae was collected by monomeric prime point resolution spectroscopy. The peak of 1. 3 ppm was the peak of triacylglycerol, and the peak of water was 4. 67 ppm. the ratio of lipid to water was calculated. The differences of L3 vertebral body fat to water ratio and fat ratio between different sex, age and BMI, waist circumference group were compared. To analyze the correlation between age and the ratio of lipid to water and fat in L 3 vertebrae. Results there was no significant difference in the ratio of lipid to water and the total average of fat ratio between male and female L3 vertebrae (P 0.05). There were significant differences in the total average fat ratio of L3 vertebrae in different age groups (P 0.05). The ratio of lipid to water of L3 vertebrae in 61- 70 years old female group, The ratio of fat to fat was significantly higher than that of 30 years old, 40 years old and 50 years old or 50 years old or 60 years old, and the ratio of female L3 vertebral body fat in 2030 years group was lower than that in 70 years old group, the total average of fat water ratio of male and female in 70 years old group was significantly higher than that of 3140 years old group of 2030 years old and 51 year old group of 50 years old, and the age group of 2030 years old. The fat ratio of male and female group was significantly higher than that of female group of 30 years old group (P 0.05 0. 05%). 20 30 years old group of male and female fat ratio of 60 years old group was significantly higher than that of male and female group. The total mean value of all cases was lower than that of 41 / 40 / 51 / 50 / 51 / 60 / 60 / 60 / 60 / 70 / 70 group and 31 / 40 / 50 / 50 / 51 / 60 age group respectively. The difference was statistically significant (P 0.05). There was no significant difference in lipid / water ratio and fat ratio of L3 vertebrae between different BMI and male and female groups with different waist circumference. There was a positive correlation between age and fat ratio in L 3 vertebrae. Conclusion the bone fat content of lumbar vertebrae is correlated with age, sex and waist circumference.
