Project Summary

When data collection began in 1994, Add Health was expected to be a five-year study analyzing how social and environmental factors shape adolescent health. Twenty-four years later it has continued to follow participants into adulthood. 'We're hoping Add Health will become an aging study,' says Kathleen Mullan Harris, the current director and principal investigator of Add Health. 'And it'll be the only aging study that begins in early adolescence and should continue and tell us a lot about the aging process and what matters.'
