Predictors of Sleep Quality in Older Persons Attending the Outpatient Clinics in a Tertiary Hospital in Nigeria.

Abstract

Background: Good quality sleep is critical to human functioning as decline in sleep quality has been linked with health issues. One of the factors that has been identified with decline in sleep quality is increasing age, making older persons at risk of significant deleterious consequences on their physical, social, and mental spheres of well-being when they have poor sleep quality.

Objectives: This study aimed at determining the predictors of sleep quality among older persons aged 60 years and above attending the outpatient clinics of a tertiary hospital in Uyo, South-South Nigeria with a view to suggesting appropriate recommendations for health improvement of participants and clinical practice, where necessary.

Methodology and methods: This was a cross-sectional study involving two hundred and fourteen (214) respondents. Those who met the inclusion criteria were interviewed with the aid of a semi- structured questionnaire containing items on socio-demographic characteristics, clinical data, and items from the Pittsburgh sleep quality index. Data was analysed using Epi info® version 3.5.1.

Results: Of the 214 respondents recruited, the prevalence of good sleep quality was 63.1% with a higher rate of poor sleep quality observed in males (57%). Factors affecting sleep quality after bivariate analysis in this study were age group (70-74 years), polygamous family type, significant stress, sleep problems, chronic medical illness, routine medication, high blood pressure, overweight and obesity. However, when multiple logistic regression was done on these factors, family type, sleep problems, and chronic medical illness were still statistically significant.

Conclusions: More than one-third of the older persons had poor quality of sleep in this study, and the predictors of sleep quality were family type (polygamous), sleep problems, and chronic medical illness. Therefore, there is need for a careful routine assessment of sleep among older persons and this should include comprehensive sleep history as well as evaluation and treatment of various co-morbidities in order to improve sleep quality among them.
