The relationship between personal unsecured debt and mental and physical health: a systematic review and meta-analysis

摘要

This paper systematically reviews the relationship between personal unsecured debt and health. Psychinfo, Embase and Medline were searched and 52 papers were accepted. A hand and cited-by search produced an additional 13 references leading to 65 papers in total. Panel surveys, nationally representative epidemiological surveys and psychological autopsy studies have examined the relationship, as have studies on specific populations such as university students, debt management clients and older adults. Most studies examined relationships with mental health and depression in particular. Studies of physical health have also shown a relationship with self-rated health and outcomes such as obesity. There is also a strong relationship with suicide completion, and relationships with drug and alcohol abuse. The majority of studies found that more severe debt is related to worse health; however causality is hard to establish. A meta-analysis of pooled odds ratios showed a significant relationship between debt and mental disorder (OR = 3.24), depression (OR = 2.77), suicide completion(OR = 7.9), suicide completion or attempt (OR = 5.76), problem drinking (OR = 2.68), drug dependence (OR = 8.57), neurotic disorder (OR = 3.21) and psychotic disorders (OR = 4.03). There was no significant relationship with smoking (OR = 1.35, p N .05). Future longitudinal research is needed to determine causality and establish potential mechanisms and mediators of the relationship.
