目的探讨绝经后哈萨克族妇女髋部体质指数(BMI)与骨密度(BMD)的相关关系。方法对符合条件的1 009名绝经后哈萨克族妇女进行髋部BMD及BMI检测,按BMI的不同分为低体质量组、正常体质量组和超体质量组,比较3组身高、年龄以及BMD的差异。再将3个组按年龄分为41~50岁、51~60岁、61~70岁、71~80岁、81~90岁5个亚组,比较各亚组BMD的不同。结果绝经后哈萨克族妇女正常体质量组、超体质量组BMD均显著高于低体质量组,差异有统计学意义(P<0.05)。随年龄增大,各组骨密度均有所下降(P<0.05)。正常体质量组、超体质量组60岁以上亚组BMD均高于低体质量组,差异有统计学意义(P<0.05);71~80岁亚组中超体质量组BMD高于正常体质量组,差异有统计学意义(P<0.05)。结论 BMI、年龄是影响哈萨克族绝经后妇女髋部BMD的重要因素,对低BMI及高龄人群应定期监测BMD,早期发现骨量减少和骨质疏松,以便进行早期干预治疗。
Objective To investigate the relationship between hip mass index (BMI) and bone mineral density (BMD) in Kazakh women after menopause. Methods One hundred and niney postmenopausal Kazakh women who met the criteria were tested for hip BMD and BMI. According to the differences of BMI, they were divided into low body weight group, normal body weight group and super body mass group. The height, age and BMD The difference. The three groups were divided into 5 subgroups: 41-50 years old, 51-60 years old, 61-70 years old, 71-80 years old and 81-90 years old. The differences of BMD in each subgroup were compared. Results The BMD of normal body weight group and overweight group of Kazakh women were significantly higher than that of the low body weight group after the menopause. The difference was statistically significant (P <0.05). With age, bone mineral density decreased in all groups (P <0.05). BMD in normal body mass group and overweight group were significantly higher than those in low body weight group (P <0.05), BMD in super body mass group was significantly higher than that in normal body weight group Group, the difference was statistically significant (P <0.05). Conclusions BMI and age are the important factors affecting the hip BMD of Kazakh postmenopausal women. BMD should be monitored regularly in low-BMI and elderly population. Early detection of osteopenia and osteoporosis may be necessary for early intervention.
