正文 Passage

A. Two different things

You can spend every day surrounded by other people and still feel lonely. You can also spend long periods alone without finding the experience distressing.

That difference may help explain why loneliness affects health differently from social isolation. In a new study, my colleagues and I found evidence that loneliness may contribute to poorer mental health and wellbeing, and to some measures of poorer general health. Social isolation appeared to have a narrower influence, with the clearest evidence involving poorer wellbeing.

B. Definitions

Around one in six people worldwide experiences loneliness, according to the World Health Organization. Loneliness is the distress someone feels when their relationships do not provide the closeness or connection they want. Social isolation describes the number and frequency of a person's social contacts. The experiences can overlap, although a person may experience either one without the other.

Previous research has linked loneliness and social isolation with poorer mental and physical health, including depression and cardiovascular disease.

C. Two-way relationship

These patterns cannot establish cause and effect. Loneliness might contribute to ill health, while illness can restrict someone's activities and relationships. Poverty, disability and childhood circumstances may also influence both health and social connection.

Our study used several statistical approaches with different strengths and sources of bias. Taken together, the results suggest that loneliness may contribute to depression and increase the risk of self-harm or a suicide attempt. It may also reduce life satisfaction and other aspects of wellbeing.

We found evidence that the relationship can operate in the opposite direction. Depression may increase loneliness, while poorer wellbeing may increase both loneliness and social isolation.

D. Physical health links

Loneliness was linked to poorer general health, including multimorbidity, which means living with two or more long-term health conditions. We found no consistent evidence that loneliness or social isolation affected the specific physical-health outcomes examined. These were coronary artery disease, heart failure, stroke, systolic blood pressure and type 2 diabetes.

This does not rule out an effect. Some estimates were too imprecise to support a firm conclusion, and previous longitudinal studies have reported links between loneliness, isolation and physical illness.

E. Combining evidence

In the study, we used an approach known as triangulation. This involves studying the same question using methods affected by different potential sources of bias. When several approaches produce similar results, researchers can be more confident that the conclusion is not driven entirely by the limitations of one method.

First, we analysed information from UK Biobank, which has collected health, lifestyle and genetic information from around 500,000 people in the UK.

We then compared siblings from the same families. Because siblings often share aspects of their childhood environment and genetic background, these comparisons can help account for family influences that might otherwise distort the results.

F. Limitations and implications

The research has several limitations. Loneliness was measured using one question asking whether participants often felt lonely. Social isolation was assessed through household size and the frequency of visits from friends or family.

This measure did not include contact through work, group activities or other parts of social life. The findings therefore relate to these particular measures and may not capture every form of loneliness or isolation.

However, it strengthens the evidence that loneliness may contribute to poorer mental health and wellbeing, and that loneliness and social isolation should be examined separately.

This distinction may affect how support is designed. Increasing opportunities for social contact may reduce isolation. Addressing loneliness may require support focused on the quality of relationships and whether people experience them as close, trusting and meaningful.
