Social and behavioural factors in Non suspicious unexpected death in infancy; experience from metropolitan police project indigo investigation
BackgroundRisk 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.MethodsRetrospective 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.ResultsSUDI 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.ConclusionsRoutinely 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.
