The risk of sudden infant death among siblings has long been overestimated: in all epidemiological studies the risk of recurrence remains at 1% or below, thereby excluding a hereditary hazard. Compared with the general population, the risk is increased in only a small percentage of families which can be detected (familial gastrooesophageal reflux or vagal hyperreflexibility, psychosocial problems and, more rarely, hereditary pathology). In the vast majority of families the relative risk is not objectively augmented. In all cases counselling of the parents is necessary for them to accept a new child.
在所有流行病学研究中，复发风险仍保持在1%或以下，因此排除了遗传风险。与普通人群相比，只有一小部分可检测到的家庭风险增加（家族性胃食管反流或迷走神经反射亢进、心理社会问题，以及更罕见的遗传病理）。在绝大多数家庭中，相对风险并未客观增加。在所有情况下，都有必要为父母提供咨询，以便他们接受新的孩子。
