睾酮水平与突发性婴儿死亡综合征有关

 
 
在一项最新研究中，一项尸体解剖后的血液分析显示，死于突发婴儿死亡综合征(SIDS)的男性婴儿睾酮水平显著高于作为对照的婴儿。

这项研究包括了127例SIDS尸体解剖和42例对照。SIDS男性婴儿睾酮水平比男性对照要高120%。女性SIDS婴儿的睾酮水平比女性对照要高50%。另一方面，雌二醇水平在两个组中都不显著。这些结果报道在2005年11月《儿科学期刊》之上。

作者指出早期动物实验和人体研究显示，睾酮水平升高与睡眠中的呼吸抑制有关。

作者还指出，在出生后性激素水平升高与SIDS风险年龄范围之间有着“惊人的巧合”，高峰都出现在1月龄和5月龄。他们承认他们的研究样本较小，需要更多的研究来探讨睾酮素水平升高与SIDS之间的关系。

Testosterone Level Linked to SIDS
 
In a new study, a postmortem blood analysis showed that male babies who died of sudden infant death syndrome (SIDS) had testosterone levels that were much higher than those of control babies.

The study involved 127 SIDS autopsies and 42 controls. The SIDS males had testosterone levels that were 120% higher than the male controls. Testosterone levels in female SIDS babies were 50% higher than the female controls. Estradiol levels, on the other hand, were not significant in either group. The findings were reported in the November 2005 issue of the Journal of Pediatrics.

The authors noted that earlier evidence in animal models and human studies had suggested that elevated testosterone levels may be linked to breathing that is depressed in sleep.

The authors also noted that there is “a striking coincidence” between postnatal rises in the sex hormones and the age range of risk for SIDS, with both peaking between one and five months of age. They acknowledged that their study sample was small and that more research is needed to understand the relationship between high testosterone and SIDS.
