漢中市兒童超聲骨密度檢測結果分析

［摘 要］目的 了解漢中市兒童骨密度情況，為臨床防治兒童骨強度不足提供依據。方法 選取2020年6月到2022年7月間在漢中市中心醫院兒童保健科做超聲骨密度檢查的32 855例兒童為研究對象，比較不同性別、年齡、季節間骨密度檢測結果的差異。結果 本次超聲傳導速度（SOS）平均值為（3 297.90±212.77）m/s，男童組的SOS均值高于女童，差異有統計學意義（t=3.99，P＜0.001）；SOS值整體上隨年齡組增長（F=3 956.21，P＜0.001）；不同季節組間SOS值差異有統計學意義，組間比較顯示夏季SOS值最高，春季最低（F=39.97，P＜0.001）。整體骨強度正常檢出率為45.90%，偏低25.59%，輕度不足15.35%，不足13.16%；男童組的骨強度不足檢出率低于女童組（Z=-21.50，P＜0.001）；0歲組的骨強度不足檢出率高于其他年齡組（H=8 214.68，P＜0.001）；春、冬季組骨強度不足檢出率高于夏、秋季組（H=71.35，P＜0.001）。結論 漢中市兒童的骨密度有明顯的性別、年齡、季節特征，有相當大的一部分群體存在骨強度不足的情況，應當引起重視。在兒童保健工作中，應持續跟蹤監測骨強度不足兒童的骨密度情況，針對性采取防治措施，保證兒童骨骼健康發育。

Analysis of ultrasound bone density testing results of children in Hanzhong

［Abstract］ Objective To understand the bone density of children in Hanzhong and provide a basis for the clinical prevention and treatment of insufficient bone density strength in children. Methods A total of 32，855 children who underwent ultrasound bone density examinations at the department of child healthcare in Hanzhong Central Hospital from June 2020 to July 2022 were selected as the study subjects.The differences in bone density test results among different genders，ages，and seasons were compared. Results The average value of the speed of sound （SOS） was （3 297.90±212.77） m/s.The mean SOS in the male group was higher than that in the female group，and the difference was statistically significant （t=3.99，P＜0.001）.The SOS value overall increased with age （F=3 956.21，P＜0.001）.There were statistically significant differences in SOS values among different seasonal groups，with the highest SOS value observed in summer and the lowest in spring （F=39.97，P＜0.001）.The overall detection rate of normal bone strength was 45.90%，with 25.59% being slightly low，15.35% showing mild insufficiency，and 13.16% indicating insufficiency.The detection rate of insufficient bone strength in the male group was lower than in the female group （Z=-21.50，P＜0.001）.The detection rate of insufficient bone strength in the 0-year-old group was higher than in other age groups （H=8 214.68，P＜0.001）.The detection rates of insufficient bone strength in the spring and winter groups were higher than those in the summer and autumn groups （H=71.35，P＜0.001）. Conclusion The bone density of children in Hanzhong shows significant gender，age，and seasonal characteristics.A considerable portion of the population exhibits insufficient bone strength，which should be taken seriously.In childrens healthcare work，it is important to continuously monitor the bone density of children with insufficient bone strength and take targeted preventive and treatment measures to ensure healthy bone development in children.

兒童期是骨骼發育和生長的關鍵時期，這一階段骨密度的增長會對骨骼健康和長期骨強度產生重要影響。良好的骨密度有助于兒童獲得強健的骨骼系統，減少骨折的風險，促進身高的增長和正常的體態發育。兒童的骨密度不僅和遺傳、疾病、運動等個體因素有關，還受氣候、環境、飲食結構等區域因素的影響［1-2］。因此，了解一個地區兒童的骨密度情況對當地兒童骨骼疾病的防治有重要意義。……
