California ? A new University of California Davis study on physician job satisfaction found differences among medical specialties, with the happiest doctors caring for children and the elderly.

That doctors treating seniors are among the most satisfied contradicts trends in medical schools, where students mostly avoid the specialty because it’s perceived to be unprofitable and unglamorous.

“Satisfaction ought to be a factor to students when they select their specialty,” said Paul Leigh, lead author and a professor in the University of California Davis Center for Healthcare Policy and Research.
