Multiple episodes of depressive symptoms over time linked to higher risk of stroke

Which subpopulations are more susceptible to mental health issues after experiencing a disaster?

In this study authored by former Harvard Bell Fellow Adel Daoud, PhD, and our faculty affiliate Ichiro Kawachi, and their collegues, a machine learning approach to parsing out differences in mental health problems after a disaster-related traumatic experience (in this case, older Japanese adults who lived in an area hard hit by the 2011 Great East Japan Earthquake) revealed that some subgroups experienced severe impacts. Those found to be most…

Why is the proportion of deaths from COVID-19 in nursing homes far less in Japan than in U.S.?

Ichiro Kawachi, MBChB, PhD, and his colleague Kazuhiro Abe, MD, PhD have written an op-ed in JAMA Health Forum that suggests that differences in standards of care and financing may be partially responsible for what appears to be differing infection rates between nursing homes in Japan and the U.S.

Affirmative action bans linked to increased smoking among minority students in their teens (and beyond)

Authors include Harvard RWJF Health & Society Scholars program alumni Rourke O’Brien and Alexander Tsai (who is also a Harvard Pop Center faculty member) as well as…

Parenting style carries weight when it comes to offspring’s mid-life BMI

A study published in Preventive Medicine has found that an authoritative parenting style (one that blends both warmth and control) is associated with healthier mid-life weight among offspring. Harvard Pop Center Director Lisa Berkman, and faculty members Ichiro Kawachi and Laura Kubzansky, are among the authors*. *Other authors include: lead author Ying Chen and Claudia Trudel-Fitzgerald.

Middle and high school racial composition linked to misuse of non-medical prescription painkillers later in life

A study by Harvard Pop Center director Lisa Berkman, faculty members Ichiro Kawachi and Mauricio Avendano, and colleagues has revealed that both white and black students who attended majority-white schools were at higher risk of lifetime, non-medical use of prescription painkillers. Blacks who attended predominantly white schools were twice as likely to report misuse compared to blacks who attended predominantly black schools.
