“…Studies have found that significant numbers of physicians in diverse countries are overweight, sedentary, drink alcohol to excess, self-medicate, suffer high levels of stress, and neglect seeking appropriate preventive and curative clinical care for themselves (Vaillant et al, 1972;Nyman, 1991;Janes et al, 1992;Caplan, 1994;Baldwin et al, 1997;Firth, 1997;Townsend, 2001). While some studies show that whereas many medical students enter the profession with reasonably good health habits, some do not (Coe et al, 1982;Sobal, 1986;Parkerson et al, 1990;Konen & Fromm, 1992;Najem et al, 1995;Kamien & Power, 1996), and many may be vulnerable to stress and psychological illness (Ironside, 1966;Vaillant et al, 1972;Richman, 1992). Thus, improving the health and lifestyle of medical students would be expected to protect them from the health risks of their chosen profession and allow them to gain significant additional years of healthy life.…”
