While studying birth cohort issues, the authors focused also on the seasons of birth in amyotrophic lateral sclerosis (ALS). The analyses were based on computerized death records of Swiss mortality statistics 1969-1993. The results confirm an excess of births in spring months. They suggest that risk factors in ALS can be acquired very early in life, thus introducing a long latency period.
在研究出生队列问题时，作者们还关注了肌萎缩侧索硬化症（ALS）患者的出生季节。分析基于1969 - 1993年瑞士死亡率统计的计算机化死亡记录。结果证实春季出生的人数过多。这表明ALS的风险因素可能在生命早期就已获得，从而导致较长的潜伏期。
