Your job could predict whether you get diabetes.

The diabetes rate has climbed to a new high in America. While 10.6% of adults had the condition in 2008, now 11.6% do, according to findings from the Gallup Sharecare Well-Being Index released Wednesday. And while that may seem like a small uptick, it’s not: “If the diabetes rate had held steady at its 2008 level rather than increased, 2.5 million fewer U.S. adults would have the disease today,” the report reveals.

Age and income also impact your risk of diabetes – the younger you are, the less likely you are to get it. Just 1.8% of adults under 30 has it, compared to nearly one in four people ages 65 and up. And the more affluent you are the less likely you are to get it: 18.5% of people who make less than $24,000 a year have diabetes, compared to a little over 6% of those making $120,000 or more. This is likely because affluent people have the money to afford more nutritious food and exercise regimens, which can help prevent diabetes.

In some occupations, the incidence of diabetes is higher than in others. The chief among them: Transportation workers, whose diabetes prevalence is 10.3%. Among the big factors contributing to this are their high levels of obesity and smoking. “People like long-haul truck drivers, for instance, don’t have much opportunity to get exercise, they’re constantly on the road so they don’t have access to a lot of great, nutritious food,” a Gallup spokesperson tells Moneyish.

6 professions with the highest risk of diabetes
1. Transportation, 10.3% of workers have diabetes
2. Farming, fishing or forestry, 8.5%
3. Service industry, 7.7%
4. Clerical or office workers, 7.7%
5. Business owners, 7.5%
6. Manufacturing or production workers, 7.5%

Meanwhile, doctors have the lowest risk. “Our theory is probably that they know better than anyone the effects of diabetes and they know how to prevent it in themselves. There also could very well be an effect from the fact that physicians make more money, which also leads to lower diabetes rates.
