Background The reasons why people live in squalor have been the subject of
much debate but little systematic research other than reports of case serie
s from secondary health-care services. We did a study in the community usin
g standardised instruments to investigate the relation between squalor and
mental and physical disorders.
Methods We did a cross-sectional study of the clients of a local-authority
special cleaning service. Levels of domestic squalor and self neglect were
measured with the living conditions rating scale, and diagnoses of mental d
isorder were made by use of WHO's schedules for clinical assessment in neur
opsychiatry (SCAN).
Findings 91 individuals were eligible for inclusion; 81 from 76 households
consented and were interviewed (a response rate of 89%). 41 (51%) were youn
ger than 65 years of age. 57 individuals (70%) were diagnosed as having a m
ental disorder at interview, as defined by the SCAN, and 21 participants (2
6%) had a physical health problem which contributed significantly to the un
clean state of their living environment. Those with a contributory physical
disorder had a lower severity of domestic squalor. People older than 65 ye
ars were less likely to have a mental disorder than those younger than 65 y
ears, but a contributory physical disorder was not associated with the pres
ence of active mental disorder. Only 30 (53%) of the 57 individuals with ac
tive mental disorder had had any contact with mental-health services in the
previous year.
Interpretation People who live in squalor and who receive special cleaning
services have high rates of mental disorder, and squalor affects younger as
well as older people. Living in squalid conditions in the group was genera
lly associated with a mental or physical disorder. and there were possible
deficits in the health care received. The extent to which these disorders m
ight respond to more assertive treatment from health services requires furt
her study, but questions are raised about the adequacy of their current hea
lth care.
