PHILADELPHIA — Some Pennsylvania college students are upset their school is requiring those who are overweight to take a fitness class to graduate.

The mandate at Lincoln University has raised the eyebrows of some legal scholars, who wonder if it creates privacy and discrimination issues.

Officials at historically black Lincoln said Friday the school is simply concerned with students' health. They say obesity and diabetes are problems especially in the African-American community.

This year's senior class is the first to be affected by the requirement. Officials said about 80 students, or 16 percent, have not yet met the mandate.

Lincoln serves about 2,000 undergraduates.
