Skid, I doubt whether any specific experiments have been performed in this area, but you could use
http://www.ncbi.nlm.nih.gov/sites/entrez?db=PubMed as a starting point. Use the keywords "airline AND pilot" and take it from there.
Most of the studies into pilot health I've seen, appear to be concerned with the effects of sun exposure, not shift patterns.
If your querying pilot mortality, (when you will die), you may be better asking the insurance guys. You may find information on morbidity, (how you will live), on pubmed or glean some further information on here.
Cheers,
