【摘要】： 目的探討青少年手腕部骨齡標準,了解呂梁地區(qū)漢族青少年手腕部骨發(fā)育的變化趨勢,為法醫(yī)學(xué)研究及法醫(yī)實際檢案過程中的年齡推斷提供可借鑒的參考數(shù)據(jù)。 方法以山西呂梁地區(qū)青少年為研究對象,按照納入標準,選取7～19歲的男性青少年379人,女性青少年381人,拍攝左手后前位片(包括腕部),根據(jù)《中國人手腕骨發(fā)育標準CHN法》對手腕部骨進行評分計算骨齡,進行骨齡與生活年齡的相關(guān)分析和骨齡性別差異分析,然后對骨齡與生活年齡進行線性回歸分析,建立骨齡推斷生活年齡的回歸方程。 結(jié)果骨齡與生活年齡呈高度正相關(guān),男性r=0.993(P0.01),女性r=0.971(P0.01),總體r=0.969(P0.01)。男性7～17歲、女性7～16歲年齡組骨齡均值大于生活年齡。建立骨齡推斷生活年齡的回歸方程2個,所有線性回歸方程經(jīng)線性回歸模型假設(shè)檢驗,均有統(tǒng)計學(xué)意義(p0.01),男女回歸方程的相關(guān)系數(shù)分別為0.993、0.995,均有統(tǒng)計學(xué)意義(p0.01)；回歸方程的標準誤分別為0.048、0.034。 結(jié)論呂梁地區(qū)青少年的骨發(fā)育水平提前,因此有必要制定新的反映青少年骨發(fā)育水平的骨齡標準,以供法醫(yī)骨齡推斷年齡提供更為準確的參考數(shù)據(jù)。建立的回歸方程可用于呂梁地區(qū)青少年生活年齡的推算。
[Abstract]:Objective to explore the bone age standard of wrist in adolescents and to understand the trend of wrist bone development in Han nationality in Lv Liang area, and to provide reference data for forensic research and age inference in forensic medical practice. Methods A total of 379 male adolescents and 381 female adolescents aged 7 to 19 years were selected as subjects of study in Lv Liang area of Shanxi Province. The posterior anterior films of left hand (including wrist) were taken. The bone age was calculated according to the CHN method of wrist bone development standard of Chinese wrists, and the correlation between bone age and life age and the sex difference of bone age were analyzed. Then the regression equation of bone age and life age was established by linear regression analysis. Results there was a high positive correlation between bone age and life age (r = 0.993 (P 0.01), r = 0.971 (P 0.01), r = 0.969 (P 0.01). The mean bone age of male 7 ~ 17 years old and female 7 ~ 16 years old group was higher than that of life age group. Two regression equations were established to estimate the age of life. All linear regression equations were statistically significant (p0.01), and the correlation coefficients of male and female regression equations were 0.993 and 0.995, respectively (p0.01). The standard error of regression equation was 0.048% 0.034. Conclusion the bone development level of adolescents in Lv Liang area is ahead of schedule, so it is necessary to establish a new bone age standard to reflect the bone development level of adolescents in order to provide more accurate reference data for coroner's bone age inference. The regression equation can be used to calculate the life age of adolescents in Lv Liang area.
