收集了颅脑损伤５６０例的临床资料，按年龄分为七组：１～４岁，５～１４岁，１５～２４岁，２５～３４岁，３５～４４岁，４５～５４岁，≥５５岁，采用有序分组资料的线性趋势检验和ｘ２检验，统计分析各年龄组的预后及与诸多临床因素的关系。再次证实了即使是相同的头部损伤的情况下，老年患者的死亡率及病残率高于年轻患者，认为年龄对预后的作用是连续的而无阈值，其既是一个持续性危险的因素，又是一个无条件的决定因素，老年患者除死亡率高于年龄轻患者外，而且于伤后７２小时～２周更易死亡。
The clinical data of 560 cases of traumatic brain injury were collected and divided into seven groups according to their ages: 1 to 4 years old, 5 to 14 years old, 15 to 24 years old, 25 to 34 years old, 35 to 44 years old, 45 to 54 years old, ≥55 We used the linear trend test and x2 test of grouping data to statistically analyze the prognosis of various age groups and the relationship with many clinical factors. Once again confirmed that even in the case of the same head injury, elderly patients with morbidity and disability rates higher than younger patients, that the effect of age on the prognosis is continuous without a threshold, which is both a persistent risk factors, It is also an unconditional determinant. Elderly patients have a higher death rate than younger patients and are more likely to die 72 hours to 2 weeks after injury.
