【摘要】 目的：分析X线下儿童不同年龄段的骨龄检测情况。方法：选取2021年10月—2023年10月于民航西安医院及西安安琪儿妇产医院行X线下骨龄检测的儿童82例，骨龄测定方法采用TW3-CRUS法，比较不同年龄段儿童骨龄、生活年龄及两者差值(D值)，采用Pearson相关性分析儿童骨龄与生活年龄的相关性，并分析不同性别儿童的D值分布情况。结果：男性9～11岁年龄段骨龄高于生活年龄，差异有统计学意义(P<0.05)，3～5岁、6～8岁及12～14岁年龄段生活年龄与骨龄差异无统计学意义(P>0.05)。女性6～8岁和9～11岁年龄段骨龄高于生活年龄，差异有统计学意义(P<0.05)，3～5岁和12～14岁年龄段生活年龄与骨龄差异无统计学意义(P>0.05)。6～8岁、9～11岁年龄段女性儿童D值均大于男性，差异有统计学意义(P<0.05)。Pearson相关性分析显示，男性与女性儿童骨龄均与生活年龄呈正相关，差异有统计学意义(P<0.05)。不同性别儿童生活年龄、身高、体质量、血压及骨龄比较差异无统计学意义(P>0.05)；女性D值分布处于1<D≤2的比例高于男性，差异有统计学意义(P<0.05)。结论：多个年龄段儿童骨龄大于生活年龄，尤其体现在男性9～11岁，女性6～11岁年龄段，骨龄与儿童生活年龄呈正相关，且女性骨龄发育具有提前趋势，应予以重点关注。更多还原

【Abstract】 Objective To analyze the bone age detection of children at different ages under X-ray.Methods A total of 82 children who underwent X-ray bone age detection in Xi’an Hospital of Civil Aviation and Xi’an Angel Maternity Hospital from October 2021 to October 2023 were selected.TW3-CRUS method was used to determine bone age,life age and the difference between them (D value) in children of different ages.Pearson correlation was used to analyze the correlation between bone age and life age in children.The D value distribution of children of different genders was analyzed.Results Bone age in males at 9-11 years old was higher than that at life age (P<0.05),but there was no significant difference between bone age and life age at 3-5 years old,6-8 years old and 12-14 years old (P>0.05).Bone age in females at 6-8 years old and 9-11 years old was higher than that at life age (P<0.05),but there was no significant difference between life age and bone age at 3-5 years old and 12-14 years old (P>0.05).The D value of female children aged 6 to 8 years old and 9 to 11 years old was higher than that of male children (P<0.05).Pearson correlation analysis showed that bone age was positively correlated with life age in both male and female children (r=0.972,0.988,P<0.05).There were no significant differences in life age,height,weight,blood pressure and bone age among children of different genders (P>0.05).The proportion of D value distribution of women in 1 < D ≤ 2 was significantly higher than that of males (P<0.05).Conclusion Children of multiple ages have a bone age greater than their age at life,especially in the age group of 9-11 years old for males and 6-11 years old for females.Bone age is positively correlated with the life age of children,and the bone age development of females has an advanced trend,which should be paid attention to.更多还原
