摘要
目的：探讨盘县与都匀两地农村苗族女性6~12岁儿童骨发育的差异性。方法：收集1 126名苗族女性6~12岁儿童作为研究对象,其中盘县535名,都匀591名;分别进行问卷调查,采用摄片法拍摄右手腕部X片,参照骨发育分级标准、骨24项骨骼发育指标进行阅片,通过数学模型法计算骨龄,然后利用SPSS16.0软件对骨龄与生活年龄的比值进行两地间的差异性比较;同时测量儿童身高、坐高、前臂长和下肢长等指标,并对影响骨发育相关因素进行Logistic多元回归分析。结果：两地农村苗族女性6~12岁儿童身高、坐高、前臂长、下肢长均值随着年龄的增大而增长;盘县9~10岁、10~11岁、11~12岁年龄段儿童身高、坐高、前臂长、下肢长均值与都匀同年龄段比较差异均有统计学意义（P〈0.01）,其余年龄段差异无统计学意义（P〉0.05）。盘县女性儿童骨发育在9~10岁（不含10周岁）年龄段比都匀超前约0.30岁,在10~11岁（不含11周岁）年龄段比都匀超前约0.27岁,在11~12岁（不含12周岁）年龄段比都匀超前约0.41岁;多因素logistic回归分析结果表明,居住海拔高度、每天户外运动时间、饮食习惯、每周腌制食品摄入量等是影响苗族6~12岁女性儿童骨骼发育的相关因素。结论：贵州盘县与都匀两地农村苗族女性6~12岁儿童骨发育存在地区差异性,盘县女性儿童的骨骼发育早于都匀女性儿童,呈现先慢后快的趋势。
Objective: To explore the difference of bone development of Miao girls aged 6- 12 years old in Pan county and Duyun,Guizhou. Methods: A total of 1 126 Miao girls aged 6- 12 years old were collected as study objects,including 535 girls from Pan county and 591 girls from Duyun; a questionnaire survey was conducted,right wrist radiography was performed,bone development grading criteria and 24 bone developmental indexes were selected as reference indexes; mathematical model method was used to calculate bone age,SPSS16. 0 software was used to compare the difference of ratio of bone age and chronological age between the girls in Pan county and Duyun; the indexes( body height,sitting height,length of upper limb,length of forearm) were measured; the related influencing factors of bone development were analyzed by logistic multivariate regression analysis. Results: The average values of body height,sitting height,length of upper limb and length of forearm increased with age of Miao girls aged 6- 12 years old in Pan county and Duyun; there were statistically significant differences in the average values of body height,sitting height,length of upper limb and length of forearm between children aged 9- 10 years old,10- 11 years old and 11- 12 years old in Pan county and the children in the same age groups in Duyun( P < 0. 01),there was no statistically significant difference among the other age groups( P > 0. 05). The age of bone development in girls aged 9- 10 years old( 10 years was excluded) in Pan county was earlier by 0. 30 years,the age of bone development in girls aged 10- 11 years old( 11 years was excluded) in Pan county was earlier by 0. 27,the age of bone development in girls aged 11- 12 years old( 12 years was excluded) in Pan county was earlier by 0. 41 years; multivariate logistic regression analysis showed that the related influencing factors of bone development of Miao girls aged 6- 12 years old in Pan county and Duyun included living altitude,outdoor exercise time every day,food habits and the weekly intake of pickled food. Conclusion: There is regional difference in bone development of Miao girls aged 6- 12 years old in Pan county and Duyun,bone development of girls in Pan county is earlier than that of girls in Duyun,which shows a trend of ' fast to slow'.
