How is it that the United States spends the most money on healthcare, and yet still has the one of the lowest life expectancies of all developed nations? (To be specific: $9,400 per capita, 79 years, and 31st.)
Maybe those of us in healthcare have been looking at it all wrong, for too long.
Healthy lifestyle and longevity
Researchers from the Harvard T.H. Chan School of Public Health conducted a massive study of the impact of health habits on life expectancy, using data from the well-known Nurses’ Health Study (NHS) and the Health Professionals Follow-up Study (HPFS). This means that they had data on a huge number of people over a very long period of time. The NHS included over 78,000 women and followed them from 1980 to 2014. The HPFS included over 40,000 men and followed them from 1986 to 2014. This is over 120,000 participants, 34 years of data for women, and 28 years of data for men.
The researchers looked at NHS and HPFS data on diet, physical activity, body weight, smoking, and alcohol consumption that had been collected from regularly administered, validated questionnaires.
