NEW ORLEANS — Smoking 20 or more cigarettes a day increases the risk of diabetes among black people, according to a preliminary study presented at the American Heart Association’s Scientific Sessions 2016.

Researchers studied nearly 3,000 black participants in the Jackson Heart study, who reported their smoking status. During the study, 466 people were diagnosed with diabetes.

While diabetes incidence was similar among those smoking less than a pack day, past smokers and neversmokers, the risk of diabetes was 62 percent higher for those smoking more than a pack a day.

Smoking cessation should be strongly encouraged in blacks with risk factors for diabetes,” researchers said.
