Truck drivers and social service workers have something in common: The people who work in these two occupations are more likely to have heart conditions, according to a new report from the Centers for Disease Control and Prevention. In the study, researchers looked at seven measures of heart health in more than 66,000 employees across 22 occupations in 21 states. To determine how heart healthy people were, the researchers counted up how many of the American Heart Association's seven "ideal" metrics of heart health each person met: whether they refrained from smoking, were physically active, had normal blood pressure and normal blood glucose, were an ideal weight, registered normal cholesterol levels and ate a healthy diet.
