Prevalence of loneliness and association with depressive and anxiety symptoms among retirees in Northcentral Nigeria: a cross-sectional study.

backgroundRetirees face numerous challenges, including disassociation from persons in their social networks in Nigeria. Perceived social isolation or loneliness could impair the quality of life in old age, and lead to mental disorders. However, it is uncertain whether perceived loneliness has an independent association with depressive and anxiety symptoms and comorbid conditions in Nigerian retirees. Therefore, we aimed at examining the association between perceived loneliness, depressive and anxiety symptoms, including comorbid conditions among retirees in Northcentral Nigeria.

methodsThis community-based cross-sectional study enrolled retirees aged 60 years and above in different pension zones from February 2019 to August 2019. A two-stage sampling procedure was used to select the study participants. Data on perceived loneliness, depressive, and anxiety symptoms were collected using the 8-item University of California, Los Angeles Loneliness Scale (ULS-8), and the DASS 21-depression and anxiety subscales, respectively. We collected information on the demographic characteristics using a well-validated structured questionnaire. Descriptive statistics, binary and multivariable logistic regression were used to examine the independent associations between loneliness, depression, anxiety, and anxious depression. P-values below 0.05 were considered statistically significant.

resultsThe mean age of participants was 71.3 (± 6.01) years, and 54.4% were men. The prevalence of loneliness, depression, anxiety, and anxious depression was 21.8, 52.0, 27.7, and 20.5%, respectively. Retirees with depression or anxiety symptoms perceived that they were lonelier than those without depression or anxiety. The multivariable logistic regression model showed that female gender (AOR 1.49; 95% CI (1.09, 2.00), having secondary education (AOR 2.24, 95% CI (1.40, 3.57) and having higher education (AOR 3.82, 95%CI (2.37, 6.16) were significantly associated with depression. Also, lonely retirees are 1.19 times (AOR 1.19; 95% CI (0.84, 1.69) more likely to be depressed compared to retirees that are not lonely, and the anxious depressed retirees are 314.58 times (AOR 314.58; 95% CI (508.05, 1941.70) more likely to be depressed than those without anxious depression.

conclusionThe prevalence of loneliness, depression, anxiety, and anxious depression were relatively high among the older retirees. Female gender and advanced age were significantly associated with perceived loneliness, depression and anxiety.
