摘要
背景:骨龄是反映青少年骨骺发育成熟程度的最佳指标。目的:对比山东省沿海和内陆地区青少年的生长发育状况及变化趋势。方法:随机选择山东省沿海地区(n=2377)和内陆地区(n=3235)9～19岁健康汉族青少年,测量其身高、体质量和胸围生长发育指标;拍摄膝踝部正位片,统计各长骨干骺融合时间。结果与结论:沿海和内陆地区男、女青少年身高、体质量和胸围均无明显差异,但同一年龄组中沿海地区测量值均大于内陆地区测量均值;沿海地区男、女青少年各长骨干骺融合时间早于内陆地区。表明山东省沿海地区青少年生长发育较内陆地区有提前的趋势。
BACKGROUND： Bone age is the best reference to reflect adolescents＇ epiphyseal maturity. OBJECTIVE： To assess the development of long bones in the knee and ankle joints of adolescents between coastal and inland areas, and to comparatively study the tendency of their skeletal development. METHODS： Healthy Han adolescents aged 9-19 years were randomly selected from Shandong Province, including 2 377 in coastal areas and 3 235 in inland areas. Three growth indicators, such as height, weight and chest circumstance were measured. The bones in the knee and ankle joints were radiated in anterior-posterior position to detect epiphysis-diaphysis time of the long bones. RESULTS AND CONCLUSION： The height, weight and chest circumstance were not significantly different in male and female adolescents between coastal and inland areas. But the values between the two areas were obviously different in the same age group. The epiphysis-diaphysis fusion time of the long bones in coastal areas was earlier than that in inland areas. Studies have shown that the growth and development of adolescents in coastal areas is more advanced than that in inland areas.
