In the @NIH newsletter! Prior work shows optimism relates to longevity in homogeneous (often White) samples. Our study, led by stellar @KogaHayami, suggests the association exists across diverse groups, with lifestyle explaining ~25% of it. @DrLewina @peterjames_7 @CKroenkeScD

Recently published research supported by @NIHAging investigated the association of optimism to longevity across racial and ethnic groups and if lifestyle choices were a mediating factor. Read more in the latest BSSR Spotlight: bit.ly/3B9Osne

In a study led by GSAS PhD student in Population Health Sciences Hayami Koga, higher levels of optimism were associated with longer lifespans and living beyond age 90 in women across racial and ethnic groups. @HarvardChanSPH buff.ly/3O4YKIv

“Although optimism itself may be affected by social structural factors, such as race and ethnicity, our research suggests that the benefits of optimism may hold across diverse groups,” said Hayami Koga, lead author of the study. hsph.harvard.edu/news/press-rel…

Using data from the Japan Gerontological Evaluation Study, @SakurakoSO, Dr. @_KSphs, Dr. @KogaHayami, and colleagues found that contrary to findings from Western populations, #optimism was unrelated to #longevity among Japanese older adults. ow.ly/yAJu50Io1ko

Hope this moves the covid discourse beyond just black and brown communities are “uniquely vulnerable” to dying due to comorbidities and towards a more thorough reckoning with who is essential, who has the means to isolate, and how resources are allocated. nytimes.com/interactive/20…


Very sad news. As a high school student wanting to become a physician, I remember being amazed when I learned that a Japanese physician was building canals in Afghanistan. “A doctor treats patients one by one, but this helps a whole village,”  nytimes.com/2019/12/04/wor…

Gender equality is way behind in Japan. One medical school explains that they were discriminating against women at their admissions because women have higher communication skills and mature faster than men. This is sadly the current status of Japan. amp.timeinc.net/time/5477556/j…
