OBJECTIVE
To investigate changes in head lag across postmenstrual age and define associations between head lag and (1) perinatal exposures and (2) neurodevelopment.
METHOD
Sixty-four infants born ≤ 30 wk gestation had head lag assessed before and at term-equivalent age. Neurobehavior was assessed at term age. At 2 yr, neurodevelopmental testing was conducted.
RESULTS
Head lag decreased with advancing postmenstrual age, but 58% (n = 37) of infants continued to demonstrate head lag at term. Head lag was associated with longer stay in the neonatal intensive care unit (p = .009), inotrope use (p = .04), sepsis (p = .02), longer endotracheal intubation (p = .01), and cerebral injury (p = .006). Head lag was related to alterations in early neurobehavior (p < .03), but no associations with neurodevelopment were found at 2 yr.
CONCLUSION
Head lag was related to medical factors and early neurobehavior, but it may not be a good predictor of outcome when used in isolation.
目的
研究月经后年龄阶段头后仰延迟的变化情况，并确定头后仰延迟与（1）围产期暴露因素以及（2）神经发育之间的关联。
方法
对64例孕周≤30周出生的婴儿在足月前及足月矫正年龄时进行头后仰延迟评估。在足月时评估神经行为。在2岁时进行神经发育测试。
结果
随着月经后年龄的增加，头后仰延迟现象减少，但58%（n = 37）的婴儿在足月时仍存在头后仰延迟。头后仰延迟与新生儿重症监护病房住院时间延长（p = 0.009）、使用血管活性药物（p = 0.04）、败血症（p = 0.02）、气管插管时间延长（p = 0.01）以及脑损伤（p = 0.006）相关。头后仰延迟与早期神经行为改变有关（p < 0.03），但在2岁时未发现与神经发育存在关联。
结论
头后仰延迟与医疗因素及早期神经行为有关，但单独使用时可能并非预后的良好预测指标。
