Kinship and cohabitation in caregiver burden 1 Viñas-Diez V, Turró-Garriga O, Portellano-Ortiz C, Gascón-Bayarri J, Reñé Ramírez R, Garre-Olmo J, Conde-Sala JL. Kinship and cohabitation in relation to caregiver burden in the context of Alzheimer's disease: a 24-month longitudinal study.
Key points• The results of the longitudinal analysis established a greater burden (ZBI) on live-in adult-child caregivers, and a smaller burden on non-live-in adult-child caregivers, with stable scores on the follow-up for both groups. Spouses had a low burden in the early stages, with a significant increase during the follow-up.• Variations between spouses and adult-child caregivers are attributable to the different nature of the marital and child-parent relationship, and to the cohabitation factor.• The different types of caregivers have relevant socio-demographic and clinical features which help to characterize them: gender, cohabitation with persons with dementia, education, marital status, sole caregiver or not sole caregiver, and the use of external resources. Generalized estimating equations (GEE) were used for longitudinal data analysis.Results: Spouse caregivers were 45.0% men, sole caregivers (> 80%), used few external resources, and had worse physical health. The number of female adult-child caregivers was higher (>75%). The live-in adult-child group, compared with the non-live-in adult-child group, were less likely to be married, had a lower level of education, were more commonly the sole caregiver, and used fewer external resources. The greatest burden was observed in live-in adult-child caregivers, and the lowest in the non-live-in adult-child group, with no significant variation in the follow-up for both groups. Spouses had an intermediate level of perceived burden, which rose significantly during follow-up (p <0.001).Conclusions: Kinship and cohabitation with the PwD were associated with different scores and evolution of the burden, with an increase in the follow-up of the spouses, and with more or less burden, depending on cohabitation, in the adult-child groups. Interventions to reduce the level of burden on caregivers should consider these differences.
