Social isolation and multiple chronic diseases after age 50: A European macro-regional analysis

Abstract

BackgroundDifferent studies have found that socioeconomic determinants influence the prevalence of chronic diseases in older people. However, there has been relatively little research on the incidence of how social isolation may affect them. We suggest that social isolation is a serious concern for people living with chronic illnesses.MethodIn this paper, we examine whether there is an increase in the propensity of being diagnosed with chronic illnesses because of a decrease in social relations for elderly Europeans. We have used a panel data for Waves 1–6 (2004–2015) of Survey on Health, Ageing and Retirement in Europe (SHARE) and logistic regressions. Besides, we have studied three geographic macro-areas (Nordic, Continental and Southern). Being diagnosed with three or more chronic diseases is considered as a dependent variable, and as social control variables we have used three isolation proxies (living alone, providing help to family, friends or neighbours and participation-club activities). Other socio-demographic variables are included (gender, age, educational level, job situation, area of location and quality of life).ResultsOur results for the full sample indicate that people who participate in social activities have fewer probability of suffering from chronic diseases (OR = 0.70, 95% CI 0.54, 0.92). For people who live alone the reverse effect is observed (OR = 1.20, 95% CI 1.04, 1.39). Differences are shown by macro-areas, e.g. providing help (OR = 0.58, 95% CI 0.34, 0.97) isolation proxy is significant for the Nordic macro-area. Club-participation activities and living alone are significant for Continental and Southern macro-areas, respectively (OR = 0.65, 95% CI 0.55, 0.82; OR = 1.46, 95% CI 1.21, 1.77).ConclusionsSocial isolation increases the risk of being diagnosed with chronic illnesses. That is, people with greater social participation have lower risk of suffering from multiple chronic diseases. This risk linked to isolation, together with the traditional one associated with lifestyles, should be considered in the development of new public policies.

Loneliness and ED Visits in Chronic Obstructive Pulmonary Disease

“…Finally, it has been found that social isolation is linked to mortality 24 . Our findings on the association loneliness with health status perception extend previous report regarding social isolation and a higher disease burden 6, 25…”

First insights on value-based healthcare of elders using ICHOM older person standard set reporting

“…A meta-analysis study of 19 studies reported moderate to severe chronic pain in 10-14% participants [25], which was similar to our findings. Participation and social inclusion are key components of healthy aging; 26.8% prevalence of loneliness was consistent with previous reports [26]. Although measuring physical performance is not always easy in daily practice, the ICHOM included walk speed as a Tier 3 metric because it matters to older adults [27]; the mean speed of 0.9 m/s in this sample was much lower than reported in older healthy adults [28], reflecting that all participants were multimorbid.…”

The association of multimorbidity, loneliness, social exclusion and network size: findings from the population-based German Ageing Survey

“…Social exclusion is associated with poor self-rated health and depression in old age [26]. Furthermore, a longitudinal study by Cantarero-Prieto and colleagues showed that socially isolated people have a higher probability of being diagnosed with three or more chronic conditions [27]. A larger social network, a somewhat more objective measure [28], is associated with a reduced risk of subsequent mortality in older women [29].…”
