Preventing loneliness in children of depressed mothers may reduce adolescent suicidality
2021-01-25
(Press-News.org) Children of mothers experiencing depressive symptoms are more at risk, as adolescents, of experiencing suicidal thoughts and attempting suicide.
New research suggests that this link may be explained by loneliness, potentially opening new ways for youth suicide prevention.
The study - by the universities of Exeter, Montréal, Laval and McGill - used data from more than 1,600 families from the Québec Longitudinal Study of Child Development, a representative sample of new-borns in Quebec followed from birth to 20 years of age.
Mothers were asked about depressive symptoms (such as sadness and losing interest in formerly pleasurable activities) at regular intervals while their children were aged five months to seven years.
The resulting information gave a measure of depressive symptoms - not a clinical diagnosis of depression.
Adolescents completed self-reports about suicidal thoughts and attempts at age 13-20 years.
Children of mothers with higher levels of depressive symptoms were approximately 15% more likely to have suicidal thoughts and/or attempt suicide as adolescents compared to children of mothers with lower levels of depressive symptoms.
"We cannot say to what extent this association is due to childhood experiences, genetics or other factors," said lead author Dr Lamprini Psychogiou, of the University of Exeter.
"But identifying some of the mechanisms explaining why those children are at increased suicide risk later in life is essential to understand how to prevent suicide among children of mothers with depression."
To this aim, the authors investigated whether feeling of loneliness and social withdrawal reported by the adolescents at age 10-13 years may account for this association.
"We found that maternal depressive symptoms in the early years of a child's life are associated with those children self-reporting elevated levels of loneliness as adolescents, which, in turn, is associated with suicidality," said Dr Psychogiou.
"We do know that social relationships in general, and peer relationships in particular, are really important for adolescents. Feeling lonely in early adolescence may influence how one perceives life as being worth living.
"Our findings are important because they suggest that interventions targeting loneliness in young adolescence for children of mothers with depression, may potentially help reduce their risk of suicidal thoughts or suicide attempts later in life.
"It's important to note that our study did not examine cause and effect."
Further studies are needed to quantify to what extent reducing feeling of loneliness translates into a decrease in suicide risk for those adolescents.

As the world becomes aware of the imminent environmental crisis, scientists have begun a search for sustainable energy sources. Rechargeable batteries like lithium-ion batteries are seeing a popularity surge, concurrent with production of "greener" technologies such as electric propulsion ships (which are being developed to meet the environmental regulations by the International Maritime Organization) and other electric vehicles. But, lithium is rare and difficult to distribute, putting its sustainability in doubt while also risking sharp increases in cost. Researchers have thus turned ...

To predict when earthquakes are likely to occur, seismologists often use statistics to monitor how clusters of seismic activity evolve over time. However, this approach often fails to anticipate the time and magnitude of large-scale earthquakes, leading to dangerous oversights in current early-warning systems. For decades, studies outside the seismology field have proposed that these major, potentially devastating seismic events are connected to a range of non-seismic phenomena - which can be observed days or even weeks before these large earthquakes occur. So far, however, this idea hasn't caught on in the wider scientific community. In this special issue, EPJ Special Topics proposes the Global Earthquake Forecasting System (GEFS): the first collaborative initiative ...

Scientists have shown where bird species would exist in the absence of human activity under research that could provide a new approach to setting conservation priorities.
A study by Durham University, UK, in collaboration with the Royal Society for the Protection of Birds (RSPB), investigated how human activities such as agriculture, deforestation, and the drainage of wetlands have shaped where bird species are found in Great Britain today.
Researchers used data on the geographical distributions of bird species alongside simulation models to predict where bird species would exist today if the effects of human activities on the landscape were removed.
In this scenario there were winners ...

Public health researchers, led by UNSW Sydney, have estimated the number of cancer cases requiring surgery globally each year, predicting the number will rise from 9.1 million to 13.8 million from 2018 to 2040 - an increase of 52 per cent or 4.7 million cases.
Their research shows the greatest relative increase will occur in 34 low-income countries, where the number of cases requiring surgery is expected to more than double by 2040 (314,355 cases to 650,164, or 107 per cent).
The modelling study, published in The Lancet Oncology on Friday, analysed global demand for cancer surgery and estimated surgical and anaesthesia ...

Research team at Seoul National University (Prof. Tae-Woo Lee) and University of Pennsylvania (Prof. Andrew M. Rappe) developed perovskite light-emitting diodes (PeLEDs) with an external quantum efficiency (EQE) of 23.4%. The research results were published in Nature Photonics, which is the world-renowned international academic journal, on January 4th (Title: Comprehensive defect suppression in perovskite nanocrystals for high-efficiency light-emitting diodes).
Metal halide perovskites have very narrow spectral emission, excellent color purity, low material cost, and wide and easy color-tunability. ...

Greater sports participation among Aboriginal and Torres Strait Islander children is linked with better academic performance, according to new research from the University of South Australia.
Conducted in partnership with the University of Sydney and the University of Technology Sydney, the world-first study found that Aboriginal and Torres Strait Islander children who played organised sports every year over four years, had numeracy skills which were advanced by seven months, compared to children who did less sport.
The study used data from four successive waves of Australia's Longitudinal Study of Indigenous Children, following 303 students (with a baseline age of five to six years old) to assess cumulative sports participation against ...

A world-first discovery by researchers at Monash University and The University of Queensland could lead to faster and more effective treatments for chronic health complications, such as cardiovascular disease and cancer, with 'fluorescent' in vivo biosensors.
The research team, led by Dr Simon Corrie from Monash University's Department of Chemical Engineering and the ARC Centre of Excellence in Convergent Bio-Nano Science and Technology, took an antibody that binds EGFR (epidermal growth factor receptor) proteins and engineered it to monitor the concentration of EGFR proteins in serum solutions over time.
Co-authors of the paper, published in ACS Sensors, are Dr Christian Fercher, Dr Martina ...

They are among the largest predators ever to walk the Earth, but experts have discovered that some baby tyrannosaurs were only the size of a Border Collie dog when they took their first steps.
The first-known fossils of tyrannosaur embryos have shed light on the early development of the colossal animals, which could grow to 40 feet in length and weigh eight tonnes.
A team of palaeontologists, led by a University of Edinburgh researcher, made the discovery by examining the fossilised remains of a tiny jaw bone and claw unearthed in Canada and the US.
Producing 3D scans of the delicate fragments revealed that they belonged to baby tyrannosaurs ...

Scientists from UNSW Sydney have developed a ceramic-based ink that may allow surgeons in the future to 3D-print bone parts complete with living cells that could be used to repair damaged bone tissue.
Using a 3D-printer that deploys a special ink made up of calcium phosphate, the scientists developed a new technique, known as ceramic omnidirectional bioprinting in cell-suspensions (COBICS), enabling them to print bone-like structures that harden in a matter of minutes when placed in water.
While the idea of 3D-printing bone-mimicking structures is not new, this is the first time such material can be created at room temperature - complete with living cells ...
