what did Rahe et al conclude?
CONCLUSIONS: Rahe et al concluded that there was a link between the higher LCUs from the 6 months prior to departure and higher illness rates on board ship. When the pre-departure life changes were low, so where the onboard illness rates. However, the study indicated this relationship could be masked by onboard stressful experiences which increased the illness rate for the entire crew.
Additionally, the link was stronger for older men (over 21s) and married men.
