Yet there has been no national-level, comprehensive review of the evidence for public health emergency preparedness and response (PHEPR) practices. Recognizing this deficiency, the Centers for Disease Control and Prevention (CDC) went to the National Academies of Sciences, Engineering and Medicine three years ago and asked them to convene a national panel of public health experts to review the evidence for emergency preparedness and response. The committee members included Stanford Health Policy Director Douglas K. Owens. The committee issued its findings July 14 with a report at a Zoom conference.

In June 24, 2020, California Governor Gavin Newsom remarked on a disturbing phenomenon: health officers are “getting attacked, getting death threats, they’re being demeaned and demoralized.” At least 27 health officers in 13 states (including Nichole Quick of Orange County in southern California, Ohio Health Director Amy Acton, and West Virginia Health Officer Cathy Slemp) have resigned or been fired since the start of the coronavirus disease 2019 (COVID-19) pandemic. Across the US, health officers have been subject to doxing (publishing private information to facilitate harassment), angry and armed protesters at their personal residences, vandalism, and harassing telephone calls and social media posts, some threatening bodily harm and necessitating private security details.

There is general consensus among experts that K-12 schools should aim to reopen for in-person classes during the 2020-2021 school year. Globally, children constitute a low proportion of coronavirus disease 2019 (COVID-19) cases and are far less likely than adults to experience serious illness. Yet, prolonged school closure can exacerbate socioeconomic disparities, amplify existing educational inequalities, and aggravate food insecurity, domestic violence, and mental health disorders. The American Academy of Pediatrics (AAP) recently published its guidance on K-12 school reentry. However, as many school districts face budgetary constraints, schools must evaluate their options and identify measures that are particularly important and feasible for their communities.

In response to the COVID-19 outbreak in December 2019, China implemented a nationwide travel blockade and quarantine policy that required all public spaces, businesses, and schools to shut their doors until further notice and placed restrictions on individuals leaving their homes or traveling. The lockdown was also implemented across China’s vast rural areas, home to more than 700 million people. These quarantine measures started during the annual Spring Festival in mid-January, when most rural residents had returned to their family homes to celebrate the Lunar New Year together. Many were migrant workers who had expected to return to China’s urban and industrial centers to continue working in factories, construction sites, and service sectors.

Recent dramatic and deadly increases in global wildfire activity have increased attention on the causes of wildfires, their consequences, and how risk from fire might be mitigated. Here we bring together data on the changing risk and societal burden of wildfire in the US. We estimate that nearly 50 million homes are currently in the wildland-urban interface in the US, a number increasing by 1 million houses every 3 years. Using a statistical model that links satellite-based fire and smoke data to pollution monitoring stations, we estimate that wildfires have accounted for up to 25% of PM2.5 in recent years across the US, and up to half in some Western regions. We then show that ambient exposure to smoke-based PM2.5 does not follow traditional socioeconomic exposure gradients. Finally, using stylized scenarios, we show that fuels management interventions have large but uncertain impacts on health outcomes, and that future health impacts from climate-change-induced wildfire smoke could approach projected overall increases in temperature-related mortality from climate change. We draw lessons for research and policy.

To celebrate its May Release, the Stanford China Program hosted a virtual book launch event for Fateful Decisions: Choices That Will Shape China’s Future (Stanford University Press) on June 2nd. Joining co-authors Thomas Fingar (Shorenstein APARC Fellow, Stanford University) and Jean C. Oi (Director, Stanford China Program; William Haas Professor of Chinese Politics, Stanford University) were contributors Karen Eggleston (Senior Fellow at FSI; Director of the Asia Health Policy Program, Shorenstein APARC, Stanford University), Barry Naughton (Sokwanlok Chair of Chinese International Affairs, School of Global Policy and Strategy, UC San Diego), and Andrew Walder (Senior Fellow at FSI; Denise O'Leary and Kent Thiry Professor, Stanford University). As Fingar and Oi point out in their volume, despite China’s extraordinary growth over the past 40 years, the country’s future is uncertain. China has enjoyed optimal conditions for development since the 1980s, but new hurdles including an aging populace, the loss of comparative economic advantage, a politically entrenched elite, and a population with rising expectations will test the country’s leaders. With each focusing on a different facet of China’s challenges, the panelists gathered to share their expertise and provide the audience with a glimpse into what the future might hold for this important country.

Following an introduction from Professor Jean Oi, the program kicked off with Professor Barry Naughton of University of California, San Diego, who discussed his chapter entitled “Grand Steerage.” Professor Naughton argued that, as it plans for the future, China’s policymaking is becoming increasingly technology-focused, particularly in the realm of economic policy. Naughton further notes that China’s economy is becoming simultaneously more state-guided and more centered around technology. This decision is a gamble, though: China is investing heavily in high-tech industries, advancing massive, centrally steered projects like the Greater Bay Area initiative and the Xiong’an New District. If they are successful, says Naughton, this will indeed be an incredible success. But, if they are not, China’s losses will be major: “There’s not really a middle ground.”

After Professor Naughton was Professor Karen Eggleston, an expert on health policy in Asia. Professor Eggleston’s chapter, “Demographic and Healthcare Challenges,” deals with emerging obstacles for China’s healthcare system, including population aging and the problems that come with it, like chronic diseases and elder care. Although China’s healthcare system has improved dramatically in recent decades, it has done so unevenly, notes Eggleston: life expectancy has greatly increased, but with disparities according to income, region, and urban vs. rural status; universal healthcare is available, but the benefit level is low, effectively limiting the standard of care many can receive. The ratio of health spending to GDP is also increasing, yet it is still modest compared to high-income countries. The COVID-19 crisis has, of course, introduced even more challenges: Will China be able to distribute future vaccines equitably? Will this crisis negatively affect young people’s decisions to choose healthcare as a career? Will telemedicine, which has seen a surge under the pandemic, improve or exacerbate existing disparities? China faces a multitude of constraints and choices going forward if it hopes to meet its population’s healthcare needs.

The audience then had a chance to hear from co-editor Thomas Fingar, speaking on his chapter, “Sources and Shapers of China’s Foreign Policy.” Fingar noted three key takeaways from both his chapter and his talk: Firstly, China’s foreign policy is a fundamental part of its national policy. Secondly, the global political environment plays an important role in shaping both foreign and domestic policy which, thirdly, plays an important role in shaping foreign policy. The conditions that allowed China to flourish over the past 40 years, emphasized Fingar, are very different from those of the present. In the 1970s and 80s, China was able to take advantage of Cold War bipolarity, globalization was in its infancy, and “China was the only significant developing country willing to embark, at that time, on the export-led path of development.” In recent years, though, China’s behavior internationally has alienated other countries; there are many competitors pursuing its style of development; and its needs and aspirations have changed, requiring more raw materials and depending upon multi-national economic agreements. Fingar suggests two potential foreign policy options: China could continue with its wolf warrior diplomacy, which has “alienated essentially all China’s neighbors to some degree,” or it could return to a style more similar to that of the 1980s and 90s Reform and Opening era. It remains to be seen which style will win out.

Finally, Professor Andrew Walder concluded the program with his discussion of China’s political future at large. His chapter, “China’s National Trajectory,” follows China’s remarkable advancement in recent years and “tr[ies] to divine what a lower growth era will mean for China’s political future.” The last 40 years of rapid growth have generated support for China’s political system, more patriotism, the near eradication of democracy movements, and an elite unity not seen in the 1970s and 80s. However, low growth rates could mean a reversal for many of these trends, says Walder. While the aforementioned support for and stability of the Chinese government was maintained by ever-improving living standards and upward mobility, a low growth period (coupled with an aging population) means the government will no longer be able to rely on these trends for popular support. Rather, it will need to improve its provision of public services to address present-day challenges. Regardless, argues Walder, the low growth era will undoubtedly lead to “dynamic changes underneath the façade of stability of Chinese politics….”

Estimation of pollution impacts on health is critical for guiding policy to improve health outcomes. Estimation is challenging, however, because economic activity can worsen pollution but also independently improve health outcomes, confounding pollution–health estimates. We leverage variation in exposure to local particulate matter of diameter <2.5 μm (PM2.5) across Sub-Saharan Africa driven by distant dust export from the Sahara, a source uncorrelated with local economic activity. Combining data on a million births with local-level estimates of aerosol particulate matter, we find that an increase of 10 μg m3 in local annual mean PM2.5 concentrations causes a 24% increase in infant mortality across our sample (95% confidence interval: 10–35%), similar to estimates from wealthier countries. We show that future climate change driven changes in Saharan rainfall—a control on dust export—could generate large child health impacts, and that seemingly exotic proposals to pump and apply groundwater to Saharan locations to reduce dust emission could be cost competitive with leading child health interventions.

Millions of Americans have experienced the coronavirus pandemic directly, as they or their loved ones suffered through infection. But for most of us, the experience is defined by weeks and months on end stuck at home. The shut-ins are testing the safety of our home environments. Stress and isolation combined with another feature of American life — easy access to firearms — could form a deadly brew.

Last week we released results of a new study — the largest ever on the connection between suicide and handgun ownership — in The New England Journal of Medicine revealing that gun owners were nearly four times as likely to die by suicide than people without guns, even when controlling for gender, age, race and neighborhood.

In this New York Times OpEd piece by myself, Matthew Miller and Garen Wintemute, we write that suicide attempts are often impulsive, prompted by fleeting crises. A vast majority of people who attempt suicide survive and do not go on to die in a future suicide. But whether attempters get that second chance at life depends a lot on the method they use, which in turn depends on what is readily at hand. Firearms afford few second chances. In sum, methods matter.

Our study compiled information on 26 million Americans over 12 years. We tracked handgun acquisitions in a large sample of California residents and then compared the frequency of death among those who did and didn’t own them.

The elevated suicide rates among handgun owners were driven by their higher rates of suicide by firearm — eight times higher for men and 35 times higher for women, compared with non-owners of the same gender. By contrast, handgun owners did not have higher rates of suicide from other methods or higher rates of death by other causes. These results are consistent with those from every serious study that has examined the relationship between gun access and suicide in the United States. If anything, we find a stronger connection than most others have.

Owning Handgun Associated With Dramatically Higher Risk of Suicide

Men who own handguns are eight times more likely to die of suicide by handgun than men who don’t have one — and women who own handguns are 35 times more likely than women who don’t, according to startling new research led by SHP's David Studdert.

The Ethics and Law Behind So-Called Immunity Passports

David Studdert writes in this JAMA Viewpoint that, ideally, a clear scientific understanding and careful deliberation would precede any public or private policy that selectively relaxes restrictions based on positive tests for COVID-19 antibodies. But a measured, evidence-based approach to policymaking is likely to be overrun by hopes and demands for antibody testing.

Several myths cloud public understanding of the connection between guns and suicide. Perhaps the most pernicious is the idea that people who really want to end their lives will find a way to do it, making the presence or absence of a gun somewhat irrelevant. Decades of research on suicide tell a different story.

Owning a handgun is associated with a dramatically elevated risk of suicide, according to new Stanford research that followed 26 million California residents over a 12-year period. The higher suicide risk was driven by higher rates of suicide by firearm, the study found.

Men who owned handguns were eight times more likely than men who didn’t to die of self-inflicted gunshot wounds. Women who owned handguns were more than 35 times more likely than women who didn't to kill themselves with a gun.

While prior studies have found higher rates of suicide among people who live in homes with a gun, these studies have been relatively small in scale and the risk estimates have varied. The Stanford study is the largest to date, and it’s the first to track risks from the day of an owner’s first handgun acquisition.

“Our findings confirm what virtually every study that has investigated this question over the last 30 years has concluded: Ready access to a gun is a major risk factor for suicide,” said the study’s lead author, David Studdert, LLB, ScD, MPH, professor of medicine at Stanford Health Policy and of law at Stanford Law School.

The study published in The New England Journal of Medicine analyzed data on handgun acquisitions and deaths in a cohort of 26.3 million adult residents of California who had not previously owned handguns. The researchers followed the cohort from 2004 through 2016, and compared death rates among those who did and didn’t acquire handguns, with a particular focus on suicides by firearm versus other methods.

More than 1.4 million cohort members died during the study period. Nearly 18,000 of them died by suicide, of which 6,691 were suicides by firearms.

Often Impulsive Acts

“Suicide attempts are often impulsive acts, driven by transient life crises,” the authors write. “Most attempts are not fatal, and most people who attempt suicide do not go on to die in a future suicide. Whether a suicide attempt is fatal depends heavily on the lethality of the method used — and firearms are extremely lethal. These facts focus attention on firearm access as a risk factor for suicide especially in the United States, which has a higher prevalence of civilian-owned firearms than any other country and one of the highest rates of suicide by firearm.”

There were 24,432 gun suicides in the United States in 2018, according to the Centers for Disease Control and Prevention. Three-quarters of them involved handguns. 

Handgun ownership may pose an especially high risk of suicide for women because of the pairing of their higher propensity to attempt suicide with access to and familiarity with an extremely lethal method.

The Stanford study took advantage of the unusually comprehensive body of information on firearm sales in California. All lawful gun purchases and transfers must be transacted through a licensed firearms dealer, who then relays the information to the state’s Department of Justice, where it is archived. The research team obtained records of all firearm acquisitions dating back to 1985, then linked them to death records. 

The researchers found that people who owned handguns had rates of suicide that were nearly four times higher than people living in the same neighborhood who did not own handguns. The elevated risk was driven by higher rates of suicide by firearm. Handgun owners did not have higher rates of suicide by other methods or higher rates of death generally.

The researchers said the very high risk of suicide for female handgun owners, relative to female nonowners, was particularly noteworthy. It has long been known that women attempt suicide more frequently than men but have fewer completed suicides. The standard explanation is that the methods women tend to use are less lethal than those men tend to use. However, the study showed that this is not true for female gun owners.

“Women in our cohort who owned guns and died by suicide usually used a gun,” said Yifan Zhang, PhD, a biostatistician at Stanford Health Policy and co-author of the study. “Handgun ownership may pose an especially high risk of suicide for women because of the pairing of their higher propensity to attempt suicide with access to and familiarity with an extremely lethal method.”

Disentangling Competing Explanations

One major challenge with studies examining the relationship between gun access and suicide risk has been determining whether people who purchase handguns already have plans in place to harm themselves, or whether the presence of a handgun creates new risks.

The unique, longitudinal nature of the Stanford study helped to disentangle these competing explanations.

“There appears to be some of both happening,” said senior author Matthew Miller, professor of health sciences and epidemiology at Northeastern University. “New handgun buyers had extremely high risks of dying by firearm suicide immediately after the purchase. However, more than half of all firearm suicides in this group occurred a year or more later. Consistent with prior work, our findings indicate that gun access poses a substantial and enduring risk.” 

Other Stanford co-authors of the study are research analyst Lea Prince, PhD, and research assistant Erin Holsinger, MD — both at Stanford Health Policy; and Jonathan Rodden, PhD, professor of political science.

Researchers at Erasmus University, in the Netherlands, and the University of Melbourne, in Australia, also contributed to the work.

The research was supported by the Fund for a Safer Future and the Joyce Foundation, as well as Stanford Law School and the Stanford University School of Medicine.
