【摘要】：目的探討甘肅蘭州地區(qū)青春期舞蹈女生骨量減少發(fā)病原因,并分析其危險(xiǎn)因素,以便于有針對性地進(jìn)行干預(yù)。方法采用橫斷面整群分層隨機(jī)抽取舞蹈專業(yè)16到20歲女生462名為研究對象,使用超聲骨密度測定儀測定骨密度,并進(jìn)行骨質(zhì)T-score綜合評價(jià),發(fā)現(xiàn)骨量減少的68例,為病例組;骨量檢測正常的394例為對照組,未檢測到OP患者。對2組的年齡、身高、體重等12項(xiàng)因素予以比較分析。所得資料在單因素分析的基礎(chǔ)上,又做多元線性回歸和多因素logistic回歸。結(jié)果骨量減少的檢測率為14.72%;骨量減少發(fā)生的相關(guān)因素分析,排除進(jìn)入模型的其他作用因素后,體重指數(shù)、初潮年齡與跟骨骨強(qiáng)度指數(shù)(SI)呈線性相關(guān)(P0.05),其中體重指數(shù)對SI影響最大(r=0.121-0.112),初潮年齡與骨強(qiáng)度指數(shù)負(fù)相關(guān)(r=-0.112);月經(jīng)紊亂患病率為39.18%,患病率較高,月經(jīng)紊亂者和吸煙者發(fā)生骨量減少的危險(xiǎn)性分別是月經(jīng)正常者和不吸煙者的1.88倍和1.92倍,進(jìn)食奶制品少、進(jìn)食豆制品少和節(jié)食促使發(fā)生骨量減少的危險(xiǎn)性分別是進(jìn)食奶制品多、進(jìn)食豆制品多和不節(jié)食的1.84倍、2.20倍和2.65倍(OR值分別是1.88、1.92、1.84、2.20和2.65,其95%可信區(qū)間內(nèi)均不包含1,P均0.05),促進(jìn)發(fā)病。結(jié)論初潮年齡延遲、低體重指數(shù)、月經(jīng)紊亂、吸煙、進(jìn)食奶制品和豆制品過少及節(jié)食是甘肅蘭州地區(qū)青春期舞蹈女生骨量減少的主要危險(xiǎn)因素。
[Abstract]:Objective to investigate the causes of bone mass reduction in adolescent dance girls in Lanzhou, Gansu Province, and to analyze the risk factors for targeted intervention. Methods 462 girls aged 16 to 20 years old were randomly selected from 16 to 20 years old. Bone mineral density was measured by ultrasonic bone mineral density tester, and bone T-score was evaluated synthetically. 68 cases of bone mass reduction were found to be the case group, and 394 cases of normal bone mass test were the control group, and no OP patients were detected. The age, height and weight of the two groups were compared and analyzed. On the basis of univariate analysis, multivariate linear regression and multivariate logistic regression were performed. Results the detection rate of bone mass loss was 14.72%. After excluding the other factors that entered the model, there was a linear correlation between body mass index (BMI), menarche age and calcaneal bone strength index (SI), in which body mass index (BMI) had the greatest effect on SI (r 鈮，
