Adolescent spinal pain is a worldwide concern, with few longitudinal studies to validate concerns that an increasing number of adolescents report pain with age. The aim of the present study was to track reports of low back pain (LBP) in adolescents each year over a five-year period (between the ages of 13 and 17 years).
A longitudinal, observational, repeated-measures study, commencing in 1999. We followed a group of South Australian students throughout five years of high schooling, reporting on prevalence of recent low back pain each year.
In 1999, data were collected from 434 13-year-olds (82.5% eligible students). In the subsequent four years, the response rate from the 1999 sample was, respectively, 72.2%, 69.1%, 56.2% and 40.1%. A significant increasing prevalence of recent LBP was reported for girls and boys. The odds of girls reporting recent LBP in the final study year (fifth year) compared with the first year was 4.4 (95% CI 1.9-10.1),for boys 1.6 (95% CI 0.7-3.7). New cases of girls' recent LBP decreased consistently over the study (90% in 2000, 46.1% in 2001, 42.1% in 2002 and 33% in 2003). New boys' cases decreased in the second and third study years (85% in 2000, 45% in 2001) then increased (45.8% in 2002, 63.6% in 2003), suggesting less established patterns of occurrence.
New cases of LBP reflected a decreasing percentage of total LBP reports over each study year for girls (suggesting increasing consistency of LBP occurrence with age). A different pattern was observed for boys, with a reversal of the downward trend after age 15 years, showing an increased percentage of LBP reports that reflected new cases in the final two study years.
青少年脊柱疼痛是一个全球性问题，很少有纵向研究来证实越来越多青少年随着年龄增长报告疼痛这一担忧。本研究的目的是在五年期间（13至17岁）每年追踪青少年下背痛（LBP）报告情况。
一项始于1999年的纵向、观察性、重复测量研究。我们在南澳大利亚州的一组学生整个高中阶段的五年中进行跟踪，每年报告近期下背痛的患病率。
1999年，收集了434名13岁学生的数据（符合条件学生的82.5%）。在随后四年中，1999年样本的回复率分别为72.2%、69.1%、56.2%和40.1%。报告显示，女孩和男孩近期下背痛的患病率显著增加。在最后一个研究年度（第五年）与第一年相比，女孩报告近期下背痛的几率为4.4（95%CI 1.9 - 10.1），男孩为1.6（95%CI 0.7 - 3.7）。在整个研究过程中，女孩近期下背痛的新病例持续减少（2000年为90%，2001年为46.1%，2002年为42.1%，2003年为33%）。男孩的新病例在第二个和第三个研究年度减少（2000年为85%，2001年为45%），然后增加（2002年为45.8%，2003年为63.6%），表明发病模式不太固定。
下背痛新病例占下背痛报告总数的百分比在每个研究年度中女孩呈下降趋势（表明下背痛发病随年龄增长的一致性增加）。男孩则观察到不同模式，15岁后下降趋势逆转，在最后两个研究年度中反映新病例的下背痛报告百分比增加。
