Face to face interviews were done with a two stage design. Prevalence studies are a subgroup of cross sectional studies in which the disease outcome is dichotomous. On the other hand a cross sectional study is a perfectly fine tool for descriptive epidemiology purposes.

A cross sectional study also known as a cross sectional analysis transverse study prevalence study is a type of observational study that analyzes data from a population or a representative subset at a specific point in time. Methods we did a cross sectional epidemiological survey of the prevalence of mental disorders mood disorders anxiety disorders alcohol use and drug use disorders schizophrenia and other psychotic disorders eating disorder impulse control disorder and dementia in a multistage clustered area probability sample of adults from 157 nationwide.
