To see whether concerns about injury risk relate to children's physical activity (PA).
Two cohorts were recruited from 19 Australian schools and assessed in 2001 (T1), 2004 (T2) and 2006 (T3). The younger (n=162) was assessed at 6, 9 and 11years old, and the older (n=259) at 11, 14 and 16 years old. At T1 and T2, parents of the younger cohort reported on fear of child being injured, and whether child would be at risk of injury if they played organised sport; the older cohort self-reported injury fear. Accelerometers assessed PA at each time point. Linear regression models examined cross-sectional associations, and also associations between T1 injury fear and risk and T2 PA, and T2 injury fear and risk and T3 PA.
In the younger cohort at T2 (9 years), fear and risk were both negatively associated with moderate to vigorous PA (MVPA) (β=-0.17, 95% CI -0.30 to -0.03 and β=-0.26, 95% CI -0.41 to -0.10) and also vigorous PA (VPA). Fear was also associated with moderate PA (MPA). For the older cohort at T1, injury fear was negatively associated with MVPA (β=-0.21, 95% CI -0.35 to -0.07) and also MPA and VPA. Parental perception of risk at T1 (6 years) was negatively associated with children's MPA at T2 (9 years) (β=-0.17, 95% CI -0.32 to -0.02). Sex did not moderate any association.
Younger children and their parents need to know which sports have low injury risks. Some children may need increased confidence to participate.
探讨儿童对受伤风险的担忧是否与他们的身体活动（PA）有关。
从澳大利亚的 19 所学校招募了两个队列，并在 2001 年（T1）、2004 年（T2）和 2006 年（T3）进行了评估。年轻队列（n=162）在 6、9 和 11 岁时进行评估，年长队列（n=259）在 11、14 和 16 岁时进行评估。在 T1 和 T2 时，年轻队列的家长报告了孩子受伤的恐惧，以及孩子参加有组织的运动是否有受伤的风险；年长队列自我报告了受伤恐惧。每个时间点都使用加速度计评估 PA。线性回归模型检验了横断面关联，还检验了 T1 受伤恐惧和风险与 T2 PA、T2 受伤恐惧和风险与 T3 PA 之间的关联。
在年轻队列的 T2 （9 岁），恐惧和风险均与中等到剧烈 PA（MVPA）（β=-0.17，95%CI -0.30 至 -0.03 和β=-0.26，95%CI -0.41 至 -0.10）和剧烈 PA（VPA）呈负相关。恐惧也与中度 PA（MPA）相关。对于年长队列的 T1，受伤恐惧与 MVPA（β=-0.21，95%CI -0.35 至 -0.07）以及 MPA 和 VPA 呈负相关。T1 时（6 岁）父母对风险的感知与 T2 时（9 岁）孩子的 MPA 呈负相关（β=-0.17，95%CI -0.32 至 -0.02）。性别并没有调节任何关联。
年幼的儿童及其父母需要知道哪些运动受伤风险较低。有些孩子可能需要增加信心才能参与。
