Abstract
Objectives
The purpose of this study was to assess the influence of sex and body mass index (BMI) on the thoracic kyphosis and lumbar lordosis of adolescents and to assess the reliability and agreement of the flexicurve method for these measurements.
Methods
The study included 217 adolescents of both sexes, aged between 11 and 15 years, who were students from municipal schools in the city of São José dos Campos in São Paulo. The measurement of thoracic kyphosis and lumbar lordosis angles was performed using the flexicurve method. Descriptive analysis of the data, analysis of covariance for comparison between groups (by BMI and sex), assessment of reliability, and intrarater agreement were analyzed.
Results
There was a significant difference between the groups by BMI and sex only for lumbar lordosis. The obese group had greater lumbar angles for both sexes (female sex: 32.6° ± 7.8° [eutrophic]; 37.7° ± 7.3° [obese]; male sex: 25.3° ± 7.3° [eutrophic]; 32.2° ± 7.3° [obese]). In the comparison between the sexes, the greatest lumbar angles were found in the female sex (female sex: 32.6° ± 7.8°; male sex: 25.3° ± 7.3°) among the eutrophic. Excellent intrarater reliability was found for thoracic kyphosis (intraclass correlation coefficient, 0.86) and moderate for lumbar lordosis (intraclass correlation coefficient, 0.72).
Conclusion
Sex and BMI were associated with lumbar lordosis in adolescents and were greater in individuals with obesity and female individuals. The flexicurve method was reliable and accurate for the assessment of thoracic kyphosis and lumbar lordosis in adolescents.
目的本研究的目的是评估性别和体重指数(BMI)对青少年胸后凸和腰椎前凸的影响,并评估弯曲曲线法测量这些数据的可靠性和一致性。方法该研究包括217名年龄在11至15岁之间的男女青少年,他们都是来自圣保罗 o jossore dos Campos市市立学校的学生。采用弯曲曲线法测量胸后凸角和腰椎前凸角。对数据进行描述性分析、组间比较的协方差分析(按BMI和性别)、可靠性评估和内部一致性进行分析。结果仅在腰椎前凸方面,两组间存在BMI和性别差异。肥胖组男女腰椎角度均较大(女性:32.6°±7.8°[富营养化];37.7°±7.3°[肥胖];男性:25.3°±7.3°[富营养化];32.2°±7.3°[肥胖])。在两性比较中,女性腰椎角度最大(女性:32.6°±7.8°;男性:25.3°±7.3°)为富营养化。胸椎后凸(类内相关系数为0.86)和腰椎前凸(类内相关系数为0.72)具有良好的椎内信度。结论性别和体重指数与青少年腰椎前凸相关,且在肥胖个体和女性个体中更为显著。弯曲曲线法评价青少年胸后凸和腰椎前凸可靠、准确。
