According to a comprehensive new meta-study, social isolation and loneliness both raise the risk of all-cause mortality.

Additionally, loneliness and social isolation are connected to an increased chance of passing away in cancer patients.

Social isolation, not loneliness, is linked to a higher mortality risk in people with heart disease. A link between social isolation, loneliness, and death has been confirmed by a recent study.

The authors looked into the connections between the two events and deaths from breast cancer, cardiovascular disease, and all other causes.

According to the extensive meta analysis, having a socially isolated lifestyle was linked to a 26% higher chance of dying from any cause than persons who did not have a socially isolated lifestyle.

Although the impact of loneliness was slightly less severe, it was nonetheless alarming: compared to those who were not lonely, those who were lonely for an extended period of time had a 14% increased chance of dying.

An increase in the probability of dying from any cause or from cancer was associated with both social isolation and loneliness. For those with cardiovascular illness, social isolation was likewise linked to an increased chance of passing away.

The meta-study examined the results of 90 distinct research with 2,205,199 participants.

Social isolation vs. loneliness

The study’s finding that social isolation had a bigger impact on mortality than loneliness is one of its more intriguing findings. The two ailments could appear to be similar. But they are not equivalent:

The term “social isolation” is used in the study to describe “an objective lack of (or limited) social contact with other people, and is characterized by a person having a small social network, having infrequent social contacts, or possibly living alone.”

On the other side, “loneliness” is “a subjective feeling of distress, emerging when there is a mismatch between desired and actual social relationships.”

For instance, it is possible to feel lonely in a group of people, even if those people are known, and it is also possible to be socially isolated without experiencing emotions of loneliness.

Effects of social isolation on health

According to Dr. Rosanne Freak-Poli, a senior research fellow in epidemiology at Monash University who was not involved in the study, “two landmark meta-analytical studies have identified that social isolation is a stronger risk factor for mortality than loneliness.”

Without being part in the study, Dr. Angelina R. Sutin, a professor at Florida State University’s College of Medicine, informed us that social isolation can be detrimental for at least a few reasons even when it does not result in loneliness in the individual.

One is that socially isolated person might not have somebody to drive them to the doctor regularly, either because they don’t have transportation or because some procedures call for an assistant.

People are not always aware of changes that are happening to them or when it is time to consult a doctor, Dr. Sutin continued.

Others may be better able to spot changes and obtain the care they require. Dr. Sutin noted that “delaying care can have significant consequences in both cases.”

According to Dr. Freak-Poli’s research, social isolation might lead to some of the harmful reactions linked with loneliness. According to her studies, social isolation and loneliness both have negative consequences on one’s health, including:

  • a high blood pressure level
  • elevated triglycerides
  • obesity and excess weight
  • a lower standard of living
  • unsound mental state

Someone who is socially isolated or lonely is more likely to engage in harmful lifestyle choices, which may exacerbate their situation and make them feel even more alone and alienated, said epidemiologist Dr. Rosanne Freak-Poli.

The impact of technology on social isolation

Our growing reliance on online connections is one reason for social isolation that is frequently brought up in discourse.

For some people, using devices can be socially isolating, while for others it can be a lifeline.

The difficulty now is figuring out when and how online interactions can be good, as well as who will get the most from real-world social interaction as opposed to virtual interaction, she continued.

Dr. Freak-Poli pointed out that the method of internet communication affects whether it is beneficial or harmful.

“Social media can have advantages if it is being used to directly and meaningfully communicate with people,” she said.

According to study, apps like Teams, Zoom, or FaceTime that allow users to see each other’s faces while speaking can increase social interaction, reduce loneliness, and improve overall wellbeing.

Social connections and relationships are beneficial to health

The current meta-study, according to Dr. Sutin, is “a nice summary of that literature and calls attention to the harmful effects of both loneliness and social isolation.”

Additionally, it provides more detailed evidence showing, among particular patient populations, social isolation and loneliness raise the risk of cause-specific mortality. The study emphasises the importance of relationships and social connection as well as the serious implications of not meeting social requirements, according to Dr. Sutin.

Dr. Freak-Poli remarked, “Since they are a part of the human condition, experiencing social isolation and loneliness are regrettably likely inevitable at some point in one’s life.”

Dr. Freak-Poli declared that she thought “initiating social interaction is an achievable goal.”

She claimed to have discovered that engaging in community events at least once a month and keeping in touch with five or more close family members or friends each month can have a significant positive impact on one’s health.

Health effects of severe loneliness

According to Dr. Sutin, loneliness can have a negative impact on health in a number of ways. She noted that lonely people frequently adopt harmful lifestyle habits like:

  • smoking
  • misuse of drugs
  • a rise in sedentary behaviour
  • abandoning activities that stimulate the mind

Dr. Sutin issued a warning that lonely persons “may also be less likely to participate in preventive care and screenings that can both prevent and detect disease at its earliest possible stage, when it is most likely to be treatable.”

We learned about the negative impacts of loneliness on mental health from Dr. Mary Louise Pomeroy, Ph.D., MPH, a postdoctoral research fellow at Johns Hopkins University:

“Loneliness is of particular concern for poor mental health (depression, stress, anxiety), which may lead to a higher risk of mortality through negative health behaviors, either directly (i.e., suicide) or indirectly (e.g., smoking as a social activity or to alleviate boredom or distress).”

Of course, being alone is unpleasant, and persistent stress has been related to a number of health problems.

Although the study’s authors concluded that social isolation posed a higher risk to health than loneliness did, they did not downplay the negative effects of chronic loneliness, which can have an impact on anyone.

Extreme versus infrequent loneliness

Dr. Freak-Poli made the observation that the study is focused on extreme loneliness. “For instance, from a health perspective, feeling lonely one day a week, even if it is regular, is not all that concerning.”

However, Dr. Freak-Poli said, “There is evidence that it is likely to have an impact on their health and well-being if they experience lonely three or more days a week over time. Other studies have shown that the COVID-19 pandemic was associated with an increase in loneliness.”

The majority, if not all, COVID-related social constraints, however, no longer apply depending on where you live. She also mentioned that, in contrast to pre-pandemic days, we are now more aware of how we communicate and socialise.

For instance, after getting perspective from their previously overly busy lives, some people may prefer to socialise less.

In spite of this, the U.S. Surgeon General has issued a warning about a “loneliness epidemic” and a recommendation on the value of social connection. According to Dr. Freak-Poli, she is not shocked.

“COVID-19 altered the way we live our daily lives and increased our awareness of interpersonal interactions. It is now impossible to ignore this awareness of human social interaction, she remarked.

Dr. Freak-Poli came to the conclusion that community services and programmes are gradually being reestablished, and that this may enable people who have recently experienced loneliness make social ties.

How can loneliness affect bone health in males?

How can loneliness affect bone health in males?

Comments 0 Comment

The impact of social isolation on bone loss in mice was examined by researchers. They discovered that social isolation increased bone loss in male mice, but not in female mice.

To determine whether the same occurs in humans, more research is required. Poorer health outcomes, such as an increase in all-cause mortality, cardiovascular issues, and mental health issues, are associated with social isolation.

Psychological stress has also been connected to risk factors in previous studies.reputable source for information on osteoporosis and weak bones.

Social isolation, which is closely related to loneliness, can cause mental suffering. The relationship between social isolation and bone health is still unclear, though.

Researchers recently looked into how social isolation impacts the bone health of male and female mice. They discovered that in male mice, but not in female mice, social isolation was linked to bone loss.

The research was introduced in Chicago at ENDO 2023, the Endocrine Society’s annual meeting. The study’s non-participant assistant professor of geriatrics at McGovern Medical School at UTHealth Houston, Dr. Nahid Rianon, was our source for information on the results.

Lead author of the study and postdoctoral fellow at MaineHealth Institute for Research’s Centre for Molecular Medicine, Dr. Rebecca Mountain, also provided the following information to us.

Future research is required to fully understand the effects on humans, but the findings “may also have clinical implications as we grapple with the long-term health impacts of the rise in social isolation related to the COVID-19 pandemic.”

The bone density was decreased in isolated mice.

32 male and female mice aged 16 weeks were divided into two groups for this investigation. One mouse per cage was used in one group’s simulation of social isolation. Four mice shared one cage in the other group.

The mice were observed by the researchers in their separate environments for 4 weeks. Finally, the bone mineral density of solitary male mice decreased. Less dense and therefore more likely to break, bones with fewer minerals are less dense.

Additionally, the researchers discovered that in solitary male mice, bone volume fraction and cortical bone thickness decreased by 26% and 9%, respectively. Both measurements point to a decline in bone quality.

Further investigation found that male mice showed impaired bone remodelling, which includes the production of new bone and raises the risk of fracture.

The scientists observed that the bone loss seen in guys who were kept alone was comparable to that shown in earlier studies after orchiectomy (removal of the testicles) and ovariectomy (removal of the ovaries).

In contrast, there was no bone loss after social isolation in the present study’s female mice.

However, despite the fact that their bone mass was unaltered, the researchers discovered that isolated females exhibited higher bone resorption-related gene expression. Increased bone resorption can cause bones to degrade more quickly than they can regenerate, raising the risk of fracture.

Underlying processes

Dr. Mountain pointed out that it is unknown exactly how social isolation may cause bone loss. Her team is investigating many hypotheses, including the function of various stress hormones and the sympathetic nervous system of the body.

We also discussed the mechanisms underlying the effects of social isolation on bone health with Dr. William Buxton, a board-certified neurologist and the director of Neuromuscular and Neurodiagnostic Medicine and Fall Prevention at Pacific Neuroscience Institute at Providence Saint John’s Health Centre in Santa Monica, California, who was not involved in the study.

“My initial reaction to the connection is that performing weight-bearing workouts is one of the finest methods to preserve bone health and fend off osteoporosis. One is less inclined to leave their home if they are isolated, and as a result, they are less likely to be on their feet, he explained.

“Both depression and weight loss can result in frailty, disability, and decreased mobility, which can contribute to bone loss,” continued Dr. Rianon. Future study is required to understand the underlying metabolic alterations that cause bone loss in various medical diseases, as they are all risks for bone loss.

Why is there a sex difference?

Dr. Mountain mentioned that they are currently looking into why social isolation had distinct effects on men and women. She mentioned that oestrogen is known to protect bones, suggesting that it might be involved.

It’s also plausible that male and female mice experience solitude on different time scales or in various ways, she added.

We also discussed the sex disparities with Dr. Douglas Landry Jarvis, an orthopaedic surgeon with Novant Health in Charlotte, North Carolina, who was not involved in the study.

The synthesis of testosterone and hormonal balances may have been disrupted by a lack of social engagement, which would have had a negative impact on bone metabolism. Over a 4-week period, the female hormonal cycle may be less impacted.

Study restrictions

The study’s weaknesses, according to Dr. Mountain, are its small sample size and lack of behavioural information on how isolation influenced mice’s depressive or anxious behaviour.

Dr. Buxton said that the study’s use of caged animals meant that it was not a perfect representation of human behaviour. I don’t know if the authors documented how frequently the animals in the cages were on their feet, but I would anticipate that the community animals would be more mobile.

Dr. Rianon continued by saying that although the study suggested that male and female mice may have different bone-forming processes, it does not specify how these variations arise.

Nevertheless, she added, “It’s pretty normal to not have [such] details in the early stages of any research.”

Research implications for the future

Dr. Buxton added, “I also guess that alcohol plays a role if these results are later demonstrated in humans.”

“We are aware that drinking makes osteoporosis more likely. Alcohol is probably a link between isolation and lower bone mineral density in individuals because isolation is a risk factor for increased alcohol consumption“, the scientist hypothesized.

According to the study, no one should alter their routines, Dr. Jarvis continued. The study’s sole recommendation is that more research be done. The variable of social engagement is too broad. The amount by which the mice’s cortisol levels changed will determine if the study can be generalized to primates and perhaps even humans.
