Psychiatric Morbidity and Subjective Burden Among Carers of Outpatients of a Psychogeriatric Clinic in Southwestern Nigeria.

Few studies in Nigeria have investigated the burden of caring for elderly persons with mental illness. The aim of this study was to examine psychiatric morbidity and burden of care among caregivers of outpatients of a psychogeriatric clinic. Burden of care was evaluated with Zarit Burden Interview. A questionnaire was also used to elicit caregivers' sociodemographic and caregiving variables while psychological well-being was assessed with the General Health Questionnaire (GHQ). Overall, 52.3% had high care burden. High care burden was associated with financial difficulty (χ(2) = 9.37; df = 1; p = 0.002; OR = 3.1; 95% CI = 1.50-6.4), restrictions on caregivers' social activity (χ(2) = 4.87; df = 1; p = 0.027; OR = 2.4; 95% CI = 1.09-5.27), lack of support from relatives (χ(2) = 6.85; df = 1; p = 0.009; OR = 6.3; 95% CI = 1.35-29.6), physical health problems (χ(2) = 10.52; df = 1; p = 0.001; OR = 4.7; 95% CI = 1.75-12.7), and psychiatric morbidity (χ(2) = 4.05; df = 1; p = 0.044; OR = 2.62; 95% CI = 1.00-6.85). Psychiatric morbidity was predicted by physical health problems (OR = 3.0; 95% CI = 1.1-8.1), financial difficulty (OR = 17.2; 95% CI = 3.8-77.5), and job loss (OR = 5.3; 95% CI = 2.0-13.8). Care burden is a significant problem among caregivers of elderly persons with mental illness attending the clinic. This may have important implications for the mental well-being of the patients.
