The incidence and prevalence of depression

Depression is a metal disturbing disease that disrupts your life mentally, physically and in many other aspects of life life. The prevalence of depression is based on the approximation that relates the number of people suffering from various forms of depression research any given time. According to studies, more than ten million Americans including men, women and children suffer from depression at any given moment of time.


The incidence of depression by the annual rate of diagnosis of depression and the prevalence of depression by the number of people who suffer from depression at any given time. The incidence and prevalence of depression are the statistics of the results of various investigations and studies, these statistics are useful in approximating the onset of depression in people a year. These statistics are not quite concise, but are good enough to measure the prevalence and incidence of depression at any given point of time. The statistics for both the incidence and prevalence may vary from one another, as the incidence of a disease may be higher compared to the prevalence of the disease. For example, a patient can get diagnosed with depression but which is not necessary for the diagnosis result in prevalence. Statistics on the prevalence of various forms of depression as various research and studies in the United States are:

According to the National Institute of Mental Health (NIMH), approximately 6.5 of the women suffer from major depressive disorder at any given point of time in America, and comparatively 3.3 male population suffers from major depressive disorder at any given point of the time. According to studies by the National Institute of Mental Health Global approximately 5.3 adults and 4 teenagers suffer serious depression each year. The prevalence of postpartum depression is approximately 1 in 679 people, which is very low compared with other forms of depression.

The prevalence of dysthymia, a mild form of depression is approximately 1 in 24 people or 4.01, of which 1.6 percent of the adult population is affected population, and by the National Institute of Mental Health. The prevalence rate of depression in America is 5.30, according to various surveys and studies of NIMH. The prevalence of depression is specific for each specific country or region. The prevalence of depression vary from one country to another or from one region to another, it would be wrong to go by the statistics of a country. The incidences of depression are calculated according to the estimate of new cases of depression diagnosed by specialists. These cases are not considered to have already been diagnosed and treated while calculating the incidence of depression.

The incidence and prevalence of depression may have some problems. Such as the data source is sometimes unclear and estimating data is an approximation. Problems with how to calculate statistics, some resources are based on surveys and some of them are based on experimental studies. Experimental studies give exact statistics telephone survey or any other source does not give accurate data. Statistics could be from different years, different regions or countries. Therefore, it is not easy to say that the statistics for both the incidence and prevalence of depression are accurate.
