Is informal caregiving at odds with optimal health behaviour? A cross-sectional analysis in the caregiving partners of persons with spinal cord injury

Abstract

ABSTRACT Background The intricate relationship between caregiving and health may to some extent be determined by the burden and restrictions imposed on informal caregivers, and the impact these experiences have on health behaviours. It is assumed that a positive caregiver experience leads to health promoting behaviours in caregivers, whereas a negative experience induces the opposite. The objective of this study is to test these assumptions and to investigate the association between the caregiver experience and health behaviours in the caregiving partners of persons with severe physical impairment, due to spinal cord injury. Methods Cross-sectional survey data from 133 couples of caregiving partners and persons with spinal cord injury living in Switzerland was used. We employed multivariable regression to evaluate the associations of the caregiver experience (objective and subjective caregiver burden, and satisfaction with caregiving) with health behaviours (physical activity, fruit and vegetable consumption, alcohol consumption, smoking, and sleep duration). Results The most robust associations were found between subjective caregiver burden and health behaviours, whereby caregivers reporting a higher burden reported less physical activity (Incidence Rate Ratio [IRR]:0.41; 95% CI 0.35-0.49), more alcohol consumption (IRR: 1.46; 1.20-1.77), greater smoking intensity (IRR: 1.29; 0.95-1.73), and a higher likelihood of insufficient sleep duration (Odds Ratio [OR]: 4.98; 1.58-15.74). Caregivers, who reported high objective burden, i.e. invested long hours in caregiving, were more prone to partake in health adverse behaviours, in particular greater alcohol consumption. Results also suggested that caregivers who were satisfied in their role and who received social support in caregiving were more likely to be physically active. Conclusion Caregivers suffering from high emotional and time burden may benefit from both practical and psychological support. This support may release resources enabling individuals to partake in health promoting behaviours, or to develop coping strategies to better deal with the burden of caregiving.
