Summary: A new study across 20 European countries reports that people in the lowest income deciles are far more likely to experience loneliness than those in higher income groups, even though they spend similar amounts of time socialising. Loneliness and poverty were both strongly linked to a cluster of defensive symptoms—pain, fatigue, and low mood—that were most severe among people with the least income.
The research also found that social connections reduce these symptoms, and that the protective effect of relationships is strongest for those living in poverty. These findings underscore the importance of social support as a buffer against the health impacts of economic disadvantage and point to the value of targeted community interventions for low-income populations.
Key facts:
- Income–loneliness gap: 49% of individuals in the lowest income decile reported feeling lonely in the previous week, compared with 15% in the highest decile.
- Health burden: Those who were lonely and poor showed the highest levels of pain, fatigue, and low mood.
- Social buffering: Strong social relationships most effectively reduced symptom scores among the poorest participants.

Overview: A team at the University of Oxford, publishing in Public Health, analysed data from the European Social Survey to examine links between income, loneliness, and a defensive symptom cluster characterised by pain, fatigue and low mood. The investigators report that people in lower income groups were much more likely to feel lonely despite reporting similar amounts of social contact, and that loneliness and low income combined to produce the highest symptom burden.
These results have clear implications for social, health and economic policy. They suggest that fostering strong social networks in low-income communities may help reduce the physical and mental health harms associated with poverty.
The defensive symptom cluster describes a group of frequently co-occurring symptoms—pain, fatigue, and low mood—that can be interpreted from an evolutionary perspective as the body’s response to perceived danger or scarcity. Historically, being part of a social group provided access to resources and protection; social exclusion or isolation can trigger physiological and psychological responses that conserve energy or protect the injured body, manifesting as increased pain sensitivity, lethargy and depressed mood.
The study was led by Dr Arran Davis from the School of Anthropology and Museum Ethnography at the University of Oxford. The team analysed responses from 24,505 participants across 20 European countries, drawing on round 7 of the European Social Survey.
Major findings:
- People in the lowest income decile were far more likely to report feeling lonely in the past week than those in the highest decile (49% versus 15%), despite no measurable difference in reported time spent socialising with family, friends or colleagues.
- Lonely participants had higher average scores on the symptom cluster—on average, a lonely individual scored higher than approximately two thirds of non-lonely peers. That gap was wider in the lowest income decile: a lonely person in the lowest decile had a symptom score higher than roughly 73% of non-lonely people in the same decile, compared with about 65% in the highest income decile.
- About 30% of lonely individuals in the lowest income decile had high symptom cluster scores, compared with only 2% of non-lonely people in the highest decile, highlighting how social relationships particularly influence health outcomes among those living in poverty.
- These relationships between income, loneliness and symptoms persisted even after controlling for factors such as living arrangements and marital status.
Previous research has shown that supportive social relationships can buffer the negative health effects of poverty. This analysis adds to that evidence by quantifying how the protective value of social ties increases as material resources decline, and by showing that people who are both poor and lonely experience the greatest symptom burden.
Lead author Dr Arran Davis, an evolutionary anthropologist, commented that the link between poverty and poor health is well established, and that loneliness can be as harmful to health as other well-known risk factors. He emphasised that people who are both low-income and socially disconnected face particularly marked health costs and called for more research into the causes of social disconnection and policies that bolster community support in socioeconomically disadvantaged areas.

Original research (open access): “Associations amongst poverty, loneliness, and a defensive symptom cluster characterised by pain, fatigue, and low mood” by Arran Davis et al., published in Public Health. The authors analysed a 20-country cross-sectional sample from the European Social Survey to examine how loneliness and income interact to affect a symptom cluster built from self-reported pain, fatigue and low mood.
Abstract
Associations amongst poverty, loneliness, and a defensive symptom cluster characterised by pain, fatigue, and low mood
Objective
Perceived social isolation is associated with increased pain, fatigue and depression. Prior work shows that pain and depression are more common among people with lower socio-economic status, and that social relationships can buffer some of these negative health effects. This study tested whether loneliness and low income interact to predict higher scores on a symptom cluster composed of pain, fatigue and low mood.
Study design
Cross-sectional analysis of a multi-country survey.
Methods
The analysis used a 20-country sample of 24,504 respondents from the European Social Survey round 7. Multilevel linear regression models tested the effects of loneliness, income decile, and their interaction on a symptom cluster variable calculated as the average of respondent z-scores for self-reported pain, fatigue and low mood. The authors hypothesised that loneliness and low income would interact to produce higher symptom cluster scores.
Results
Respondents in lower income deciles were substantially more likely to report loneliness (48.7% in the lowest decile versus 15.2% in the highest decile), even though reported socialising time did not differ across income groups. Multilevel regression showed: (1) lonely individuals scored about 0.447 standard deviations higher on the symptom cluster, (2) each step up in income decile corresponded to a decrease of about 0.022 standard deviations in symptom scores, and (3) a statistically significant interaction indicating that the association between loneliness and symptoms was strongest in lower income deciles.
Conclusions
Both loneliness and low income were independently associated with higher symptom cluster scores, and social relationships provided especially strong buffering effects for people experiencing poverty. These results contribute to understanding social and economic gradients in health and highlight the potential value of community-based interventions to mitigate the health consequences of socio-economic disadvantage.
