Millennium Cohort Family Study

The Millennium Cohort Family Study, a sub-study of the Millennium Cohort Study (United States), is a United States Department of Defense-sponsored project designed to evaluate the short- and long-term effects of the military experience on Service members and their families.

The Family Study also provides a unique opportunity to explore the impact of relationship quality on the physical and psychological health of Service members, their spouses and children.

A comprehensive understanding of the challenges faced by military families provides a vehicle to create truly effective interventions and support mechanisms.

For example, we know that smoking causes lung cancer and that untreated high blood pressure causes heart disease, but less than 50 years ago, these relationships were not clear.

Spouses of Service members participating in the Millennium Cohort Study were invited to complete a baseline questionnaire between 2011 and 2013 and will be re-surveyed every three years.
