Table VII. Smoking status, according to the results of a population survey made by the Heart Association in 1975 of those lawyers
(181) and physicians (63) of the present study who had participated and all the participants (8866) in the survey of the Heart
Association.

hefur verið sýnt fram á að læknar líða oft af
kulnun og eru þjakaðir af sjálfsmorðsþönkum
(49). í sumum rannsóknum hefur verið fjallað
um tengsl lyfja- og áfengismisnotkunar og
sjálfsmorða (50,51) og fyrri rannsókn á dánar-
meinum íslenskra lækna fjallaði einnig um
misnotkun lækna á lyfjum og áfengi (52). Hér
skal bent á að það eru einkum sjálfsmorð sem
framin eru með lyfjum, föstum eða fljótandi
efnum, sem eru tíðari meðal lækna en annarra
og þá sérstaklega meðal lækna sem ekki hafa
sérfræðiviðurkenningu. Hærri dánartíðni meðal
lækna sem ekki hafa sérfræðiviðurkenningu
kemur einnig heim við nokkrar bandarískar
rannsóknir á læknum sem gerðar voru fyrir
lön^u (29,30).
Aður hafa menn velt vöngum yfir skýringum
þess að læknar lifa lengur en aðrir karlar og
