According to the 2012 results of the Gallup-Healthways Well-Being Index, transportation workers, including drivers, pilots, flight attendants and air traffic controllers, had the lowest.
Gallup-Healthways asked more than 170,000 workers a series of 55 questions covering physical and emotional health, life evaluation and workplace environment.
Gallup assigned a score between 0 to 100 to each of 14 major professional categories, with 100 representing ideal well-being. Based on Gallup's score, these are the most and least satisfied professions.
While each of the 55 questions had some impact on the profession's final well-being score, certain measures highly contribute to workers' health.
These include such factors as getting regular exercise, not smoking, learning something new every day, and being treated well by their employers, to name a few.
In an interview with 24/7 Wall St., Dan Witters, research director for the Gallup-Healthways Well-Being Index, explained that the professions with high levels of obesity and related conditions like heart attacks and chronic physical pain were more likely to have much lower overall well-being.
Just 14 percent of physicians were considered obese, compared to the more than 37 percent of transportation workers.
