A health insurer is expanding efforts to market to Hispanic Americans.

Aetna Inc., Hartford, has formed an alliance with the Hispanic Association of Colleges and Universities, San Antonio.

HACU is a nonprofit group that represents more than 450 colleges and universities in the United States and other countries.

HACU member schools will offer health information through links on their Web sites, Aetna says.

Aetna also will supply speakers for HACU events and funding for the HACU annual conference, and Aetna will help HACU conduct a case study on health care disparities, Aetna says.
