As reported by the National Health Executive, loneliness and social isolation are placing a growing strain on public health in Wales, according to a new report that draws on global evidence from the World Health Organization and national data
The World Health Organization has identified social disconnection as a major public health issue worldwide, with far-reaching effects on physical, mental and social wellbeing. Public Health Wales’ latest analysis applies that global evidence to Wales, examining who is most affected and where action could make the greatest difference.
Survey data suggests loneliness remains a significant issue. Thirteen per cent of people aged 16 and over in Wales say they feel lonely, according to the National Survey for Wales. Findings from the Time to Talk Public Health panel indicate that the same proportion are socially isolated, although 71% report feeling fairly or very socially connected.
The report sets out the wide-ranging consequences of social disconnection, extending beyond health alone. It links loneliness and isolation to reduced academic achievement, higher unemployment and lower income, underlining the social and economic impact.
The physical and mental health effects are also significant. Evidence associates loneliness with a 14% increase in all-cause mortality, while social isolation is linked to a 32% rise. Both are connected to elevated risks of cardiovascular disease, diabetes, depression, anxiety and dementia.
Public Health Wales concludes that tackling social disconnection must be a priority, arguing that stronger community ties are central to improving wellbeing and building a more resilient nation.
