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1009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 determine the relationship between bone mineral density (BMD) of hip and body mass index (BMI) in postmenopausal women in Kazakh nationality. Methods BMD of hip and BMI were examined for 1 009 postmenopausal women in Kazakh nationality who were consistent with the inclusion criteria. They were divided into 3 groups according to BMI, including underweight group, normal-weight group and overweight group. Body height, age and BMD in three groups were compared. Furthermore, 5 subgroups including 41-50 years old, 51-60 years old, 61-70 years old, 71-80 years old and 81-90 years old subgroup were divided according to age, and then the differences of BMD among the subgroups were compared. Results For postmenopausal women in Kazakh nationality, BMD in normal-weight and overweight groups were higher than those in underweight group (P <0.05). With the increase of age, BMD in all groups were lowered (P <0.05). For those who were over 60 years old, BMD in normal-weight and overweight groups were higher than those in underweight group, the difference had statistical significance (P <0.05); while for those who were 71-80 years old, BMD in overweight group was higher than that in normal-weight group (P <0.05). Conclusions BMI and age were important effect factors for hip BMD in postmenopausal women in Kazakh nationality. BMD should be monitored regularly for people with low BMI, or elderly women, so as to screen osteopenia and osteoporosis, and to carry out treatment intervention in early stage.
