The Lancet: 1.5 million children worldwide have lost parent, grandparent, caregiver due to COVID-19

( Study offers first global estimates of the number of children who experienced the death of a parent, grandparent, or primary caregiver from COVID-19. Researchers estimated figures based on COVID-19 mortality data from March 2020 through April 2021, and national fertility statistics for 21 countries, and extrapolated findings to produce global estimates. Findings suggest 1 million children have lost a parent, 1.1 million have lost a parent or custodial grandparent, and more than 1.5 million have lost a parent, custodial grandparent, or other secondary familial caregiver from COVID-19. Authors call for urgent investments in services to support children who have lost their parents and caregivers.

An estimated 1.5 million children worldwide have experienced the death of a parent, custodial grandparent, or other relative who cared for them, as a result of COVID-19, according to a new study published in The Lancet.

Of those, more than 1 million children experienced the death of one or both parents during the first 14 months of the pandemic, and another half a million experienced the death of a grandparent caregiver living in their own home, the study estimates.

Children who have lost a parent or caregiver are at risk of profound short- and long-term adverse effects on their health, safety, and wellbeing, such as increasing the risk of disease, physical abuse, sexual violence, and adolescent pregnancy. The researchers call for urgent action to address the impact of caregiver deaths on children into COVID-19 response plans.

Dr Susan Hillis, one of the lead authors on the study, from the U.S. Centers for Disease Control and Prevention COVID-19 Response Team says: "For every two COVID-19 deaths worldwide, one child is left behind to face the death of a parent or caregiver. By April 30, 2021, these 1.5 million children had become the tragic overlooked consequence of the 3 million COVID-19 deaths worldwide, and this number will only increase as the pandemic progresses [1]. Our findings highlight the urgent need to prioritize these children and invest in evidence-based programs and services to protect and support them right now and to continue to support them for many years into the future - because orphanhood does not go away." [2]

Before the pandemic, there were an estimated 140 million orphaned children worldwide. These children have greater risks of mental health problems, family poverty, and physical, emotional, and sexual violence. They are also more likely to die by suicide or develop a chronic disease, such as heart disease, diabetes, cancer, or stroke.

The COVID-19 pandemic has resulted in more children facing the loss of a parent or caregiver. In addition, as older adults are the most vulnerable to COVID-19, many children living in multigenerational families will have experienced the death of a grandparent. Evidence shows that grandparents are increasingly playing key roles in providing care and financial support for their grandchildren worldwide. [3]

Study author Professor Lucie Cluver, Oxford University, UK, and the University of Cape Town, South Africa, says: "We have strong evidence from HIV and Ebola to guide solutions. We need to support extended families or foster families to care for children, with cost-effective economic strengthening, parenting programs, and school access. We need to vaccinate caregivers of children - especially grandparent caregivers. And we need to respond fast because every 12 seconds a child loses their caregiver to COVID-19." [2].

Before this report, there were no global figures to quantify how many children have been affected by the loss of a caregiver during the COVID-19 pandemic, either directly (due to the virus) or indirectly (due to another condition that was exacerbated due to the pandemic). The study's researchers developed mathematical models using the best available data as an initial attempt to estimate the magnitude of this hidden impact of the pandemic on children.

Implementing methods similar to those used by the UNAIDS Reference Group on Estimates, Modelling and Projections for estimating the number of children orphaned by AIDS [4], the authors based the COVID-19 orphanhood estimates on mortality data for 21 countries that account for 77% of global COVID-19 deaths [5]. The analysis included both reported COVID-19 deaths between 1 March 2020 and 30 April 2021 and the number of excess deaths (when such data were available), during the same time-period, to account for variations in country-specific reporting systems.

The researchers linked COVID-19 death rates to fertility data for males and females from those 21 countries [6] to estimate the number of children who had lost a parent as a consequence of COVID-19. Loss of both parents was accounted for so that children were not counted twice.

The researchers extended their analysis to include deaths of grandparents or other older adults aged 60 to 84 years who were living in the same household as the children, based on United Nations Population Division's statistics on household composition. These figures take into account custodial grandparents (living with grandchildren in absence of parents), who have primary responsibility for their grandchildren's care, as well as co-residing grandparents and other older family members, who live in the same household (with grandchildren and parents) and have secondary, but not primary caring responsibilities.

Mathematical modelling was used to extrapolate the findings from these 21 countries to the rest of the world, using country-level data on COVID-19 deaths and fertility rates. The model showed a high correlation between female fertility rate and the ratio of orphans to deaths.

The findings suggest that at least 1,134,000 children experienced the death of their mother, father, or custodial grandparents, as a consequence of COVID-19. Of these, an estimated 1,042,000 lost their mother or father, or both. Overall, 1,562,000 children are estimated to have experienced the death of at least one parent or a custodial or other co-residing grandparent (or other older relative).

Countries with the highest rates of children losing their primary caregiver (parent or custodial grandparent) included: Peru (1 child per 100, totalling 98,975 children), South Africa (5 children per 1,000, totalling 94,625 children), Mexico (3 children per 1000, totalling 141,132 children), Brazil (2 children per 1,000, totalling 130,363 children), Colombia (2 children per 1,000, totalling 33,293 children), Iran (>1 child per 1,000, totalling 40,996 children), USA (>1 child per 1,000, totalling 113,708 children), and Russian Federation (1 child per 1,000, totalling 29,724 children).

In April 2021, in India, the researchers estimate an 8.5-fold increase in the numbers of children newly orphaned (43,139) compared to March 2021 (5,091).

For almost every country, deaths were greater in men than women, particularly in middle and older ages. Overall, up to five times more children lost their fathers than lost their mothers.

The authors note that children experiencing COVID-19-associated deaths of parents or caregivers are at greater risk of family separation and institutionalization, such as being placed in orphanages or care homes. They argue this should be avoided because it has negative effects on social, physical, and mental development.

Dr Seth Flaxman, one of the study's lead authors, from Imperial College London, UK, says: "The hidden pandemic of orphanhood is a global emergency, and we can ill afford to wait until tomorrow to act. Out of control COVID-19 epidemics abruptly and permanently alter the lives of the children who are left behind. Tomorrow is too late for the child institutionalized in an orphanage, who will grow up profoundly damaged by the experience. We urgently need to identify the children behind these numbers and strengthen monitoring systems, so that every child can be given the support they need to thrive." [2]

The researchers say their findings are likely underestimates because figures for a number of countries included in the study were based on COVID-19 mortality only and excess death data were unavailable. COVID-19 deaths may be underreported because of variability in SARS-CoV-2 testing and reporting systems.

Dr Juliette Unwin, another lead author from Imperial College London, UK, adds, "Our study establishes minimum estimates--lower bounds--for the numbers of children who lost parents and /or grandparents. Tragically, many demographic, epidemiological, and healthcare factors suggest that the true numbers affected could be orders of magnitude larger. In the months ahead variants and the slow pace of vaccination globally threaten to accelerate the pandemic, even in already incredibly hard-hit countries, resulting in millions more children experiencing orphanhood." [2]

The authors note some limitations to their results. Their study is based on the best available data, but many countries do not have robust reporting systems for deaths or fertility. Additionally, data on country-specific prevalence of orphans before the pandemic was lacking, so their estimates of double orphans are limited to deaths of both parents during the pandemic.

Writing in a linked Comment, Assistant Professor Rachel Kentor of Baylor College of Medicine, USA and Amanda Thompson of Inova Schar Cancer Institute, USA, (who were not involved in the study), say: "By answering the authors' call to expand our worldwide pandemic response to include caring for children, the global community can capitalise on this momentum; we can harness the current global attention on children bereaved by the pandemic to mobilise resources and implement systemic, sustainable supports for bereaved youth around the world."

As part of this work, the authors developed a real-time COVID-19 calculator [7], providing ongoing updated estimates of COVID-19-associated orphanhood and death of caregivers for every country in the world. These estimates as of the end of April 2021, along with an evidence-based strategy for action as described in the paper, can also be found in a policy report authored by the Global Reference Group for Children Affected by COVID: "Children: The Hidden Pandemic 2021 - A joint report of COVID-19-associated mortality and a strategy for action."

New research could help clear backlog of surgery since it shows use of airway device in

New research published in Anaesthesia (a journal of the Association of Anaesthetists) by researchers from the University of Bristol can help to improve the efficiency of surgery and help tackle the growing backlog of surgery caused by the COVID-19 pandemic. During the pandemic, the number of patients waiting for routine surgery in the UK has almost doubled with more than 5.3 million people awaiting surgery including more than 300,000 waiting more than a year. A contributory factor is that COVID-19 precautions have led to many operating theatres working at 75-50% of normal working efficiency. Staff working in operating theatres have been required to take special precautions at the start and end of operations to allow viral particles ...

More than 1.5M children lost a primary or secondary caregiver due to the COVID-19 pandemic

More than 1.5 million children around the world are estimated to have lost at least one parent, custodial grandparent, or grandparent who lived with them due to death related to COVID-19 during the first 14 months of the pandemic, according to a study published today in The Lancet. The study highlights orphanhood as an urgent and overlooked consequence of the pandemic and emphasizes that providing evidence-based psychosocial and economic support to children who have lost a caregiver must be a key part of responding to the pandemic. The analysis used mortality and fertility data to model rates of COVID-19-associated orphanhood (death of one or both parents) and deaths of custodial and co-residing grandparents (ages 60-84) from March 1, 2020 to April 30, 2021, across 21 countries. This study ...

A substance from Saussurea controversa will help bone tissue regeneration

Metabolic bone diseases, including osteoporosis, when bones lose their mass and become so fragile that they could be damaged while sneezing or under little stress, are called the silent epidemic of the 21st century. A person does not even know about his illness before the first symptom - it can be a fracture of the spine or the neck of the hip. According to statistics, every third woman and every fifth man after 50 have osteoporosis. Thus, it is promising to search for and obtain substances and materials for implants that have osteoinductive properties and are capable of initiating the processes of transformation of stem cells into bone. Certain trace elements, such as calcium and magnesium, influence the processes of bone regeneration ...

Virginia Tech's COVID-19 testing demonstrates power, versatility of academic labs

Virginia Techs COVID-19 testing demonstrates power, versatility of academic labs
In the early days of the pandemic, scientists at Virginia Tech created a COVID-19 testing laboratory and novel test for the virus from scratch. They not only developed a test in-house that avoided the reagent supply shortages that hampered testing efforts nationwide, but also used 3D-engineered supplies and stable storage media, enabling samples to be transported to rural sites in Virginia without the need for constant refrigeration. This novel protocol for transforming a research laboratory into a testing operation capable of processing more than 130,000 ...

Microbially produced fibers: Stronger than steel, tougher than Kevlar

Microbially produced fibers: Stronger than steel, tougher than Kevlar
Spider silk is said to be one of the strongest, toughest materials on the Earth. Now engineers at Washington University in St. Louis have designed amyloid silk hybrid proteins and produced them in engineered bacteria. The resulting fibers are stronger and tougher than some natural spider silks. Their research was published in the journal ACS Nano. To be precise, the artificial silk -- dubbed "polymeric amyloid" fiber -- was not technically produced by researchers, but by bacteria that were genetically engineered in the lab of Fuzhong Zhang, a professor ...

Small-scale worker resistance impacts food delivery economy in China

ITHACA, N.Y. - Small-scale. Short-lived. All digital. Out of public view. That's how a new form of collective worker resistance is unfolding in China's app-based food delivery economy, new Cornell University research finds. Though highly fragmented and not always successful, "mini-strikes" by small groups of food couriers - conducted via WeChat - reflect a new form of leverage, suggest Chuxuan "Victoria" Liu and Eli Friedman, associate professor in the ILR School. Food couriers are able to maintain complete physical invisibility, and each individual worker can 'strike' from anywhere, they write. The scholars interviewed couriers, in-person and online, who delivered food for, an Alibaba-owned company that controlled ...

Research shows employer-based weight management program with access to anti-obesity medications results in greater weight loss

Tuesday, July 20, 2021, CLEVELAND: A Cleveland Clinic study demonstrates that adults with obesity lost significantly more weight when they had access to medications for chronic weight management in conjunction with their employer-based weight management program, compared to adults who did not have access to the medications. The study was published in JAMA Network Open. Obesity is a complex disease that is caused by multiple factors, including genetic, environmental, and biological. A lifestyle intervention with a focus on nutrition and exercise is often not enough to treat obesity, which is a chronic disease that requires long-term therapy. The U.S. Food and Drug ...

Study: Wireless radiation exposure for children is set too high

WASHINGTON - A peer-reviewed study by the Environmental Working Group recommends stringent health-based exposure standards for both children and adults for radiofrequency radiation emitted from wireless devices. EWG's children's guideline is the first of its kind and fills a gap left by federal regulators. The study, published in the journal Environmental Health, relies on the methodology developed by the Environmental Protection Agency to assess human health risks arising from toxic chemical exposures. EWG scientists have applied the same methods to radiofrequency radiation from wireless devices, ...

Strong immune response underlies acute kidney injury related to COVID-19

ROCHESTER, Minn. -- Mayo Clinic researchers have found that acute kidney injury associated with COVID-19 resembles sepsis-caused kidney injury, and the immune response triggered by the infection plays a pivotal role. The findings, published in Mayo Clinic Proceedings, also suggest that mitochondrial dysfunction -- a loss of function in cellular energy production -- is commonly found in kidney injury related to COVID-19. More than one-third of hospitalized COVID-19 patients report acute kidney injury, and sudden kidney failure is a risk factor for in-hospital mortality, according to studies published last ...

Muddied waters: Sinking organics alter seafloor records

The remains of microscopic plankton blooms in near-shore ocean environments slowly sink to the seafloor, setting off processes that forever alter an important record of Earth's history, according to research from geoscientists, including David Fike at Washington University in St. Louis. Fike is co-author of a new study published July 20 in Nature Communications. "Our previous work identified the role that changing sedimentation rates had on local versus global controls on geochemical signatures that we use to reconstruct environmental change," said Fike, professor of earth and planetary sciences and director of environmental studies in Arts & Sciences. "In this study, we investigated organic carbon loading, or how much ...
