Americans spend more time living with diseases than people from other countries, according to a new study. The AMA's latest findings show that Americans live with diseases for an average of 12.4 years. Mental and substance-use disorders, as well as musculoskeletal diseases, are main contributors to the years lived with disability in the U.S., per the study. Women in the U.S. exhibited a 2.6-year higher so-called healthspan-lifespan gap (representing the number of years spent sick) than men, increasing from 12.2 to 13.7 years or 32% beyond the global mean for women. The latest overall healthspan-lifespan gap in the U.S. marks an increase from 10.9 years in 2000 to 12.4 years in 2024, resulting in a 29% higher gap than the global mean.
