Abstract
BackgroundThere are concerns that the prevalence of mental disorder is
increasing.AimsTo determine whether the prevalence of common adult mental disorders has
increased over time, using age–period–cohort analysis.MethodThe study consisted of a pseudocohort analysis of a sequence of three
cross-sectional surveys of the English household population. The main
outcome was common mental disorder, indicated by a score of 12 or above
on the Revised Clinical Interview Schedule (CIS-R). Secondary outcomes
were neurotic symptoms likely to require treatment, indicated by a CIS-R
score of 18 or over, and individual subscale scores for fatigue, sleep
problems, irritability and worry.ResultsThere were 8670 participants in the 1993 survey, 6977 in the 2000 survey
and 6815 in the 2007 survey. In men a significant increase in common
mental disorder occurred between the cohort born in 1943–9 and that born
in 1950–6 (odds ratio 1.4, 95% CI 1.1–1.9) but prevalence in subsequent
cohorts remained largely stable. More extended increases in prevalence of
sleep problems and mental disorders were observed in women, but not
consistently across cohorts or measures.ConclusionsWe found little evidence that the prevalence of common mental disorder is
increasing.
