Background
There is a paucity of data describing how general practitioners (GPs) label or record depression.
Aims
To determine incidence and sociodemographic variation in GP-recorded depression diagnoses and depressive symptoms.
Method
Annual incidence rates calculated using data from 298 UK general practices between 1996 and 2006, adjusted for year of diagnosis, gender, age and deprivation.
Results
Incidence of diagnosed depression fell from 22.5 to 14.0 per 1000 person-years at risk (PYAR) from 1996 to 2006. The incidence of depressive symptoms rose threefold from 5.1 to 15.5 per 1000 PYAR. Combined incidence of diagnoses and symptoms remained stable. Diagnosed depression and symptoms were more common in women and in more deprived areas.
Conclusions
Depression recorded by general practitioners has lower incidence rates than depression recorded in epidemiological studies, although there are similar associations with gender and deprivation. General practitioners increasingly use symptoms rather than diagnostic labels to categorise peoples illnesses. Studies using standardised diagnostic instruments may not be easily comparable with clinical practice.
