Different types of teenage friendships critical to wellbeing as we age – study
Being a teenager is hard, confusing — and crucially important.
Scientists studying teenage socialising have found that teenaged friendships could lay essential foundations for wellbeing in later life, and that not just the kinds of friendships teenagers experience but the timing of those friendships is critical.
Emily Shah of the University of Arkansas is first author of the article in Frontiers in Developmental Psychology.
The researcher said: “A teen’s perception of how broadly socially accepted they are by their peers in early adolescence is particularly influential in predicting adult wellbeing.
“Conversely, in late adolescence, the quality of their more intimate close friendships is more influential for predicting adult wellbeing.”
Coming of age
Our relationships with other people affect how we feel about ourselves, how we function in society, and our psychological wellbeing; that in turn affects our physical wellbeing.
This is especially true in our teenage years, when we start to rely on our peers’ support, and when puberty puts our bodies under strain.
Relationships can also help manage the stressful transitions teenagers deal with, from exams to new jobs to leaving home.
Dr David Szwedo of James Madison University, corresponding autho, said: “Friendships during the teenage years provide youth with one of their first forays into intimate consensual relationships.
“Because friends may come and go, friendships are a context in which teens must develop skills to maintain and grow the friendship or risk its loss.
“These skills are likely to be subsequently helpful for forming future friendships and longer-term romantic relationships.”
The researchers recruited 184 participants attending an American middle school.
They surveyed these students at ages 13-14, then again at ages 17-18, measuring the quality of their close friendships, their perceived social acceptance, and their likability as reported by their peers.
Finally, the researchers caught up with these teenagers as adults aged 28-30 to ask them about their physical and mental health, job satisfaction, romantic insecurity, and experience of aggression.
Friendships are teenagers’ foundations
Overall, the researchers found that perceived social acceptance was the best predictor of adult wellbeing.
When contacted as adults, teenagers who thought their peers liked them reported lower levels of social anxiety and aggression, better physical health, professional and romantic satisfaction, and feeling more socially connected.
However, likability as reported by teenagers’ peers did not predict any facet of adult wellbeing well — possibly suggesting that a teenager’s own perception of their social success is particularly important.
However, when the authors examined the two stages of adolescence separately, adult wellbeing was best predicted by social acceptance for young teenagers and close friendships for older teenagers.
Close friendships predicted lower social anxiety and romantic insecurity and higher job satisfaction.
The difference between the two stages of adolescence also suggests that timing is critical.
While self-perception of success could stop younger teenagers developing social anxiety, and contribute to preventing stress-linked poorer health, lower levels of social acceptance in later teenage years didn’t predict health outcomes.
The authors cautioned that, although the longitudinal design allowed them to track how wellbeing changed over time, it meant that the participants weren’t in school during the Covid-19 pandemic, which could significantly impact teenagers’ social experiences and their future wellbeing.
Additionally, the study was largely based on self-reported measures; future research might complement these with observational measures.
Shah said: “I want teens to know that they aren’t alone.
“It’s not easy being a teenager in this world, and I choose to believe that teens are doing the best that they can with the skills that they have.
“I hope that adults who interact with teenagers consider sharing that perspective, to hold space for empathy and compassion.”
Szwedo added: “It’s always helpful to keep in mind that studies such as this point to things that happen on average, and that things could be different for any individual child or teenager.
“This study reinforces the importance of caregivers being aware of their children’s social lives by talking to their kids, talking to their teachers, and knowing who they are talking to online.
“It’s helpful for parents to not only ask about who their teens’ friends are, but also how socially accepted they feel.”
Gut-friendly foods such as kimchi and kombucha may carry hidden risks for heart health when eaten in excess, the British Heart Foundation (BHF) has warned.
The charity said foods marketed as prebiotic, probiotic or otherwise good for the gut can support the microbiome, but some may also be high in salt or sugar, which can raise the risk of cardiovascular disease.
Products highlighted by the British Heart Foundation included kimchi, kombucha, fruit yoghurts, smoothies and sauerkraut. It said there is no harm in including them as part of a healthy diet, but advised people to check labels for added salt and sugar and eat them in moderation.
Tracy Parker, the charity’s nutrition lead, said: “We encourage everyone to choose foods that can keep their gut microbiome healthy. The benefits are clear, and we are continuing to improve our understanding of how a gut-friendly diet may help our hearts.
“A lot of these products can contain high levels of salt or sugar though, so it is important to be aware of the potential drawbacks.
“By ensuring you check package labels for added salt and sugars, and eat each in moderation, you can make sure the risks do not outweigh the benefits for your heart health.”
Fermented foods such as kimchi and sauerkraut are rich in probiotics, the healthy bacteria produced during fermentation that can help support a diverse and healthy gut microbiome.
However, both are traditionally made using a lot of salt, which can raise blood pressure if eaten frequently or in large quantities. High blood pressure is known to increase the risk of heart attack and stroke.
Kombucha, a fermented tea, also contains probiotics and can be a healthier alternative to fizzy drinks, but many commercial and shop-bought versions contain added sugar.
Eating too much sugar can lead to weight gain, which can increase the risk of heart attack, stroke and other cardiovascular disease.
Fruit yoghurts can contain probiotic live bacteria cultures, but may also be high in sugar and have fewer live cultures than plain versions.
The charity said plain yoghurt with live and active cultures on the label can be a lower-sugar option, with whole fruit added at home for sweetness.
Smoothies made with whole fruits provide prebiotic fibre, which feeds beneficial gut bacteria and supports digestive health.
They can also provide vitamins and antioxidants, especially when made with a variety of plant-based ingredients.
But blending breaks down the structure of fruit, releasing free sugars that behave like added sugars in the body and can cause faster rises in blood sugar levels.
Regularly consuming too much sugar can lead to weight gain, which can increase the risk of developing type 2 diabetes, heart disease and kidney disease.
The charity said only one 150ml serving of any smoothie counts towards five-a-day, and suggested adding nuts or seeds for extra protein and fibre to help keep blood sugar levels more stable.
The BHF also noted that some shop-bought sauerkraut is pasteurised, which removes most of the live bacteria.
It advised checking the label, eating small portions and choosing unpasteurised products for those seeking the probiotic benefits.
The charity said beneficial gut bacteria produce short-chain fatty acids during digestion, which are linked to reduced inflammation, better metabolism and better heart and circulatory health.
These good bacteria also help digest polyphenols, natural plant chemicals thought to have antioxidant properties and which may help lower blood pressure.
By contrast, harmful gut bacteria, which thrive on diets high in fat and red meat, produce chemicals that can cause problems in the heart and blood vessels by increasing inflammation and altering how cholesterol is processed in the body.
Beneficial bacteria thrive on varied diets high in prebiotics, non-digestible fibres found in foods such as wholegrains, oats, beans, lentils, bananas and onions.
People with diabetes may have undiagnosed heart failure that could be detected by a simple screening blood test, research suggests.
The TARTAN-HF trial found that one in four patients with diabetes who had at least one other risk factor for heart failure had undiagnosed heart failure detected through screening with a blood test and ultrasound scanning of the heart.
Experts said the findings show the extent of unrecognised heart failure in people with diabetes, and how the condition can be detected using a widely available blood test called NT-proBNP, which measures how much strain the heart is under.
They suggest a heart failure screening programme for diabetics could improve diagnosis rates, lead to earlier treatment and potentially reduce the risk of hospitalisation and death.
The study, involving 700 patients, was led by the University of Glasgow in collaboration with AstraZeneca, Roche Diagnostics, Us2.ai, NHS Greater Glasgow and Clyde and NHS Lanarkshire.
Dr Kieran Docherty, clinical senior lecturer at the University of Glasgow’s School of Cardiovascular and Metabolic Health, said: “Our results from the landmark TARTAN-HF trial identified heart failure in a large proportion of people living with diabetes, emphasising the need for a heart failure screening strategy in this group of patients.
“We know that many of the symptoms and signs of heart failure are non-specific, and may go unrecognised as potentially being due to heart failure for a long time.
“The strategy used in our trial is simple and easy to implement in clinical practice, and will aid in the early identification of heart failure in people with diabetes, and facilitate the initiation of medications that we know improve outcomes in patients with heart failure.”
The study, which began more than three years ago, involved more than 700 people with diabetes from the two health board areas who had at least one other risk factor for heart failure.
They were randomly assigned either to receive heart failure screening or to continue with their usual care.
Researchers found screening uncovered a large number of previously unrecognised cases of heart failure. Around one in four, or 24.9 per cent, of those screened were found to have the condition within six months, compared with 1 per cent in the group continuing their usual care.
The study, involving patients with type 1 and type 2 diabetes, found almost all of the participants found to have heart failure had preserved ejection fraction, which can be difficult to detect without dedicated testing.
The findings of the TARTAN-HF trial were presented at the American College of Cardiology conference taking place from 28 to 30 March in New Orleans in the US.
Dr Edward Piper, medical director at AstraZeneca UK, said: “Delayed diagnosis and treatment of heart failure in people with type 2 diabetes contributes to poor long-term outcomes. TARTAN-HF demonstrates that targeted, risk-based screening can identify previously undiagnosed heart failure in approximately one in four high-risk patients with diabetes, enabling earlier intervention with guideline-directed therapy.”
Dr Christian Simon, head of global medical affairs at Roche Diagnostics, said: “We are proud to have supported the landmark TARTAN-HF trial. These findings demonstrate the transformative power of early, accessible diagnostics like the NT-proBNP blood test.
“By identifying unrecognised heart failure in people with diabetes, we enable clinicians to initiate appropriate treatments sooner, ultimately improving patient outcomes and lives.”
The UK has launched a £6.3m men’s health fund to back local projects aimed at helping men and boys live longer, healthier lives.
The Men’s Health Community Fund is a partnership between the Department of Health and Social Care, Movember and People’s Health Trust.
The government is contributing £3m, while the two charities are more than doubling that to take the total to £6.3m.
Grants will support community projects reaching underserved men and boys aged 16 and over, particularly in the most disadvantaged areas and at key points in their lives such as becoming a father, losing a job or retiring.
Projects could include support for new fathers, activities for men facing loneliness and social isolation, services to help young men engage with the health system, and support for men in work, out of work and moving into retirement.
The programme will bring together voluntary, community and social enterprise organisations to test new ways of reaching men who are least likely to use traditional health services.
An evaluation funded through the National Institute for Health and Care Research will assess what works and help inform future policy and delivery.
Health and social care secretary Wes Streeting said: “Too many men across the country are living shorter, less healthy lives, particularly those in our most disadvantaged communities.
“This new partnership will help men get the support they need in the places they feel most comfortable, their communities, among people they trust.
“By working with expert charities and local organisations, we can reach the men who are too often missed by traditional services and help them take better care of their mental and physical health.”
“It is a key step in delivering our first ever Men’s Health Strategy and driving forward our ambition to halve the gap in healthy life expectancy between the richest and poorest areas.”
The Men’s Health Strategy sets out plans to tackle the physical and mental health challenges men and boys face.
Men can be less likely to seek help and more likely to suffer in silence, while higher rates of smoking, drinking, gambling and drug use are damaging men’s health and affecting families, workplaces and communities.
The government is also investing £3.6m over the next three years in suicide prevention projects for middle-aged men in local communities across areas of England where men are most at risk, many of which are also among the most deprived. Suicide is one of the biggest killers of men under 50, and three-quarters of all suicides are men.
The projects will aim to break down barriers middle-aged men face in seeking support, including stigma around asking for help and a lack of awareness of what is available and how to access it.
They will be co-designed with experts and men with lived experience of mental health crises and suicidal thoughts.
