Context-specific information, including differences in geographical areas, such as distinct altitudes, can be important to explain variations in physical growth. We aimed to compare the estimation of maximum growth velocity and pubertal growth-spurt parameters of children and adolescents living at low and moderate altitudes in Colombia. A cross-sectional study, including a representative cohort of 30.305 (51% boys) children and adolescents aged 1−18 years from Colombia, was performed. The heights were measured with standardized techniques. The Preece−Baines growth model was used to estimate the mathematical and biological parameters of the height-growth velocities and growth spurts for both sexes. The altitudes were categorized as low (18 to 564 m above sea level) or moderate (2420 to 2640 m above sea level). There were no differences in final height (h1), peak height velocity size (hθ), age at peak height velocity (APHV), or peak height velocity PHV (cm/y) between the subjects living in both altitudes (p > 0.05). The APHV was estimated at 12.75 ± 0.75 years in the boys and at 10.05 ± 0.65 years in the girls. The girls reached the APVH 2.70 years earlier than the boys. Regarding the PHV, the boys reached higher growth velocity, which was 6.85 ± 0.55 cm/y. In conclusion, there were no significant differences in final height, peak height, APHV, or PHV between the children and adolescents living at distinct altitudes in Colombia. The PHV occurred approximately 3 years earlier in the girls than in the boys. Furthermore, the girls’ estimated PHV, APHV, and final height were lower than those of the boys. This study allows additional insight into pubertal growth-spurt parameters and also provides a valuable reference database for the assessment of Colombian children and adolescents.
特定背景信息，包括地理区域差异，如不同海拔高度，对于解释身体生长的差异可能很重要。我们旨在比较哥伦比亚生活在低海拔和中海拔地区的儿童和青少年的最大生长速度和青春期生长突增参数的估计值。进行了一项横断面研究，纳入了来自哥伦比亚的30305名（51%为男孩）1至18岁儿童和青少年的代表性队列。身高采用标准化技术测量。使用普里斯-贝恩斯生长模型来估计男女身高生长速度和生长突增的数学和生物学参数。海拔高度分为低海拔（海拔18至564米）或中海拔（海拔2420至2640米）。生活在这两个海拔高度的受试者之间，最终身高（h1）、身高速度峰值大小（hθ）、身高速度峰值年龄（APHV）或身高速度峰值（PHV，厘米/年）没有差异（p>0.05）。男孩的APHV估计为12.75±0.75岁，女孩为10.05±0.65岁。女孩比男孩提前2.70年达到APVH。关于PHV，男孩达到的生长速度更高，为6.85±0.55厘米/年。总之，哥伦比亚生活在不同海拔高度的儿童和青少年之间，最终身高、峰值身高、APHV或PHV没有显著差异。女孩的PHV比男孩早约3年出现。此外，女孩估计的PHV、APHV和最终身高低于男孩。这项研究有助于进一步了解青春期生长突增参数，也为评估哥伦比亚儿童和青少年提供了有价值的参考数据库。
