Several studies have demonstrated a global increase in morbidity and mortality in elderly subjects with low social support or high comorbidity.

Thus, the present study was performed to evaluate the relationship between social support and comorbidity on 12-year mortality of elderly people. A random sample of 1288 subjects aged 65-95 years interviewed in 1992 was studied. Comorbidity by Charlson Comorbidity Index (CCI) score and Social Support by a scale in which total score ranges from 0 to 17, assigning to lowest social support the highest score, were evaluated. At 12-year follow-up, mortality progressively increase with low social support and comorbidity increasing (from 41.5% to 66.7% and from 41.2% to 68.3%, respectively; p < 0.001). Moreover, low social support progressively increases with comorbidity increasing (and 12.4 +/- 2.5 to 14.3 +/- 2.6; p < 0.001). Accordingly, multivariate analysis shows an increased mortality risk of 23% for each increase of tertile of social support scale (Hazard ratio = HR = 1.23; 95% CI = 1.01-1.51; p = 0.045). Moreover, when the analysis was performed considering different degrees of comorbidity we found that social support level was predictive of mortality only in subjects with the highest comorbidity (HR = 1.39; 95% CI = 1.082-1.78; p = 0.01). Thus, low social support is predictive of long-term mortality in the elderly. Moreover, the effect of social support on mortality increases in subjects with the highest comorbidity.

Abstract

Several studies have demonstrated a global increase in morbidity and mortality in elderly subjects with low social support or high comorbidity. However, the relationship between social support and comorbidity on long-term mortality in elderly people is not yet known. Thus, the present study was performed to evaluate the relationship between social support and comorbidity on 12-year mortality of elderly people. A random sample of 1288 subjects aged 65-95 years interviewed in 1992 was studied. Comorbidity by Charlson Comorbidity Index (CCI) score and Social Support by a scale in which total score ranges from 0 to 17, assigning to lowest social support the highest score, were evaluated. At 12-year follow-up, mortality progressively increase with low social support and comorbidity increasing (from 41.5% to 66.7% and from 41.2% to 68.3%, respectively; p < 0.001). Moreover, low social support progressively increases with comorbidity increasing (and 12.4 +/- 2.5 to 14.3 +/- 2.6; p < 0.001). Accordingly, multivariate analysis shows an increased mortality risk of 23% for each increase of tertile of social support scale (Hazard ratio = HR = 1.23; 95% CI = 1.01-1.51; p = 0.045). Moreover, when the analysis was performed considering different degrees of comorbidity we found that social support level was predictive of mortality only in subjects with the highest comorbidity (HR = 1.39; 95% CI = 1.082-1.78; p = 0.01). Thus, low social support is predictive of long-term mortality in the elderly. Moreover, the effect of social support on mortality increases in subjects with the highest comorbidity.
