贵阳市553例体检健康成年女性骨密度调查

Investigation of Bone Mineral Density of 553 Healthy Adult Women in Guiyang City

目的:了解贵阳市部分25～34岁健康成年女性骨密度(BMD)的分布情况及其影响因素。方法:采用超声BMD仪测定贵阳市553名健康女性右侧跟骨BMD,同时测量身高和体质量、并计算体质量指数(BMI),对调查对象进行生活方式(运动及饮奶)问卷调查;比较不同年龄、BMI、运动和饮奶组骨量情况及BMD,并对饮奶及运动间交互作用进行析因分析。结果:不同年龄组间及不同BMI组BMD比较,差异无统计学意义(P>0. 05);饮奶组BMD高于不饮奶组,运动组BMD高于不运动组,差异均有统计学意义(P <0. 05);饮奶与运动间存在交互作用(P <0. 05),BMD由大到小依次为运动+饮奶组>运动+不饮奶组>不运动+饮奶组>不运动+不饮奶组。结论:规律饮奶及规律运动对骨质疏松有一定的防护作用。

Objective:To investigate the status of bone mineral density(BMD)and analyze its influencing factors on BMD in some healthy women aged from 25 to 34 in Guiyang.Methods:Ultrasound bone densitometer was used to measure the BMD of right calcaneus in 553 healthy women in Guiyang.Their heights and body masses were measured,and the body mass index(BMI)was calculated for each participant.At the same time,we performed a survey about their physical exercise and milk drinking.We compared BMD in different age groups and BMD in different BMI groups using independent group t-test and one-way ANOVA.Factorial interaction analysis between physical exercise and milk drinking was carried out.Results:BMD was no significant difference in both different age groups and different BMI groups(P>0.05).The BMD in the drinking group was significant higher than that in the non-drinking group(P<0.05),and the BMD in the exercise group was significantly higher than that in the non-exercise group(P<0.05).In addition,there was interaction between milk drinking and exercise(P<0.05).BMD from large to small sequencing is ordered by exercises+drinking group>exercise+no drinking group>no exercise+drinking group>no exercise+Do not drink milk group.Conclusion:Regular drinking milk and regular exercise have a certain protective effect on osteoporosis.
