Insomnia and quality of life of prisoners at a Nigerian maximum-security prison

Abstract

Purpose

This study aims to determine the prevalence of insomnia as well as its association with the quality of life of the inmates in a Nigerian prison. Prisoners are a disadvantaged group of people whose needs are often unmet. Many authors have focussed on investigating the prevalence and pattern of psychiatric morbidity, as well as substance use among prisoners. However, sleep disorders, which can predispose or precipitate psychiatric disorders, have been largely neglected in research. The relationship between insomnia and quality of life (QoL) among the general population has been documented but similar investigations have yet to be conducted among the prisoner population.

Design/methodology/approach

This was a cross-sectional study with 300 male prisoners at the Ibara prison, Abeokuta, Nigeria who were not diagnosed with depressive, generalized anxiety or post-traumatic stress disorders. Each respondent was interviewed with a sociodemographic proforma, Insomnia module of the Schedule for Clinical Assessment in Neuropsychiatry and the brief World Health Organisation Quality of Life questionnaire.

Findings

About half of the respondents (45.7%) met diagnostic criteria for insomnia. A diagnosis of insomnia and some sleep-related variables were significantly associated with QoL.

Research limitations/implications

All the possible correlates of insomnia could not be investigated. Further research should be conducted to identify more correlates and investigate the impact of insomnia on prisoners’ lives.

Practical implications

Improvement of prison climate (relationships in prison, safety and order, contact with the outside world, facilities, meaningful activities and autonomy) may mitigate insomnia among prisoners. Prison psychiatry in Nigerian correctional centres should be made a priority.

Social implications

The findings have brought to light the need to address the current social welfare system in place for Nigerian correctional centres.

Originality/value

The study provided information on the prevalence of insomnia and poor QoL among prisoners in a Nigerian correctional facility.
