Perceived social isolation in a community sample: its prevalence and correlates with aspects of peoples' lives.

Although there are many studies reporting perceived social isolation or loneliness and their correlates in specific groups, there are few modern prevalence studies. This study reports on the prevalence of perceived social isolation in an Australian community sample. Randomly sampled Australian adults (n = 3,015) were interviewed using a standard questionnaire. In addition to perceived social isolation assessed by the Friendship Scale, data were collected on socio-demographic variables and chronic health conditions. The findings suggest that while most participants were socially connected, 9% reported some social isolation and 7% were isolated or very isolated. Perceived social isolation varied by gender and age group, region of birth, relationship, labourforce, and income status. A key finding was that younger adults had higher probabilities of being classified as being socially isolated than did older participants. Depression was very strongly associated with perceived social isolation. Other health conditions or life experiences associated with it were hearing, incontinence and lifetime trauma exposure. The demographic characteristics and chronic health conditions associated with perceived social isolation are structural circumstances of peoples' lives. Given there are poor long-term health outcomes, including early death and suicide, there are clear public health implications for those trapped by these life circumstances.
