“If you look at, you know, Tom Pearls and Nir Barzilai, who probably run the two largest cohorts of studying centenarians and their offspring. I mean, on average, centenarians exercise less, smoke more, eat worse.”

The claim, plainly

Dr. Peter Attia claims that, on average, centenarians in major cohort studies exercise less, smoke more, and eat worse than the general population.

Assessment

Dr. Peter Attia claimed that published data from the major centenarian cohorts led by Dr. Nir Barzilai (Longevity Genes Project) and Dr. Thomas Perls (New England Centenarian Study) show that centenarians 'on average... exercise less, smoke more, eat worse' than the general population. The published literature from these cohorts directly contradicts this assertion. In the definitive 2011 study by Barzilai and colleagues in the Journal of the American Geriatrics Society (Rajpathak et al., 2011), centenarians were found to have lifestyle characteristics (smoking history, physical activity, dietary patterns, and BMI) broadly comparable to the general birth-cohort controls (NHANES I), not worse. Specifically, ever-smoking prevalence among male centenarians was significantly lower than controls (59.6% vs. 74.5%) and equal among women (26.2%), while dietary adherence and exercise levels showed no statistically significant differences indicating worse habits. Similarly, data from Perls' New England Centenarian Study indicate that heavy smoking is exceedingly rare among centenarians. While the studies concluded that centenarians did not have exceptionally healthier lifestyles than average, they did not smoke more, eat worse, or exercise less.

Swapnil N. Rajpathak et al. (2011), 'Lifestyle Factors of People with Exceptional Longevity', Journal of the American Geriatrics Society (Longevity Genes Project cohort): ever-smoking among male centenarians was 59.6% vs. 74.5% in NHANES I controls; female smoking was identical at 26.2%.
Rajpathak et al. (2011) showed low-calorie, low-fat, and low-salt diet practices had no statistically significant differences between centenarians and general population controls.
Thomas Perls' New England Centenarian Study data found that significant smoking history among centenarians is rare.
