In the United States, Hispanic women have an average life expectancy of 87 years — six years longer than Caucasian women. Part of the reason could be that Hispanic women may have better cardiovascular health accompanied by more positive attitudes about life, according to research that was published Wednesday on the American Heart Association journal website Circulation: Cardiovascular Quality & Outcomes.

The research was originally scheduled to be released as part of the Quality of Care and Outcomes Research 2015 Scientific Sessions, which was cancelled due to violent protests in the city of Baltimore.

Researchers studied annual health fair and health risk information for 7,683 female employees (4,235 of whom were Hispanic) at a U.S. health system. The researchers looked at 21 cardiovascular health-related characteristics, including biological measures, such as blood pressure, as well as women’s knowledge of cardiovascular risk factors and health attitudes.

They found:

  • Hispanic women had notably better results in 10 of 12 biological measures, including existing heart disease conditions and risks factors, than non-Hispanic women.
  • While there was no difference among Hispanic and non-Hispanic women in their knowledge of risk factors for cardiovascular disease, Hispanic women worried less and overall had more positive attitudes about their health and life.

Although Hispanic women were significantly less inclined to want to increase their time of exercise, they were also less likely to worry about their weight, attitudes that may bode well for them, researchers said.
