Impact of Loneliness and Social Support on Acute Health Service Use and Symptom Exacerbation Among Adults with Asthma and COPD.

Abstract

Loneliness and low social support are associated with negative health outcomes among adults with asthma or COPD. Although social support is correlated with loneliness, low social support is neither necessary nor sufficient for the experience of loneliness. This study compares the relative association of loneliness and social support on symptom exacerbation (i.e., acute deteriorations in respiratory health) and acute health service utilization (i.e., hospitalizations, emergency department visits) among 206 adults with asthma and 308 adults with COPD. Separate logistic regression models were used to simultaneously examine the association of loneliness and social support with each outcome. Among adults with asthma, loneliness was associated with greater odds of hospitalization (AOR = 2.81, 95%CI [1.13, 7.02]), while low social support was not (AOR = 1.44, 95%CI [0.78, 2.65]). However, neither loneliness nor social support were associated with any other acute health service use or symptom exacerbation among adults with asthma. Among adults with COPD, loneliness, and greater social support were associated with increased odds of symptom exacerbation (AOR = 1.67, 95%CI [1.03, 2.69]; AOR = 1.36, 95%CI 1.02, 1.83]) and hospitalization (AOR = 3.46, 95%CI [1.65, 7.24]; AOR = 1.92, 95%CI [1.15, 3.22]), but only social support was significantly associated with ED visits (AOR = 1.72, 95%CI 1.12, 2.66]). These findings support prior research demonstrating that loneliness and social support are related but separate determinants of patients' physical symptoms and service utilization.
