Editor’s note: This is the fifth element in a series on how loneliness and isolation are affecting seniors at home. The series stems from writer Diane Eastabrook’s participation in the 2021 Age Boom Academy, a free training fellowship of the Columbia Journalism School and the Mailman School of Public Health.

In this McKnight’s Newsmakers podcast, Diane Eastabrook rounds out the special Lonely at Home series with a conversation with Linda Fried, M.D., dean of Columbia University’s Mailman School of Public Health. The geriatrician explains why social isolation and loneliness have become a global health crisis and how care providers can intervene.
