Background
Risk factors for Sudden
Unexpected Death in Infancy (SUDI) are well described, and such cases are now investigated
according to standard protocols. In London, Project Indigo of the Metropolitan
Police provides a unique, detailed framework for such data collection. We
investigate such data to provide a contemporary account of SUDI in a large city
and further link data to publically available datasets to investigate
interactions with social factors.
Methods
Retrospective analysis
of data routinely collected by the Metropolitan Police Service in all cases of
non-suspicious SUDI deaths in London during a six year period.
Results
SUDI deaths are
associated with markers of social deprivation in London. A significant
proportion of such deaths are associated with potentially modifiable risk
factors such as cigarette smoking and co-sleeping, such behaviour also being
associated with social factors, including accommodation issues.
Conclusions
Routinely collected data
provide valuable insight into patterns and associations of mortality, with SUDI
remaining a significant issue in London. Risk factors include social disadvantage,
which may manifest in part by affecting behavioural patterns such as
co-sleeping and public health interventions to reduce rates require significant
social modification.
