The purpose of this study was to determine whether increased body mass index is associated with accelerated skeletal maturation.
The skeletal ages of 107 children, aged 9 to 16 years, were determined by using Fishman's hand-wrist analysis. The difference between chronologic age and dental age was analyzed against body mass index, sex, and age.
The mean differences between chronologic and skeletal ages for normal weight, overweight, and obese subjects were 0.51 years, 0.44 years, and 1.00 years, respectively. Although there was a trend for obese subjects to have accelerated skeletal maturation compared with overweight and normal-weight subjects, the difference was not statistically significant. Skeletal age differences significantly decreased with increasing age. The mean skeletal age differences were 0.90 year for 9- to 13-year-olds and 0.26 year for 13- to 16-year-olds. Mean skeletal age did not differ significantly by sex.
Overweight or obese children did not have significantly accelerated skeletal maturation after adjusting for age and sex.
本研究的目的是确定体重指数增加是否与骨骼成熟加速相关。
采用菲什曼手腕分析法确定了107名9至16岁儿童的骨骼年龄。分析了实际年龄与齿龄之间的差异与体重指数、性别和年龄的关系。
正常体重、超重和肥胖受试者的实际年龄与骨骼年龄的平均差异分别为0.51岁、0.44岁和1.00岁。尽管与超重和正常体重受试者相比，肥胖受试者有骨骼成熟加速的趋势，但差异无统计学意义。骨骼年龄差异随年龄增长显著降低。9至13岁儿童的骨骼年龄平均差异为0.90岁，13至16岁儿童为0.26岁。骨骼平均年龄在性别上无显著差异。
在调整年龄和性别后，超重或肥胖儿童的骨骼成熟并未显著加速。
