Depression is a life disturbing metal illness that disturbs your life mentally, physically and in so many other aspects of life. Depression prevalence is the research based approximation that refers to number of people suffering from various forms of depression at any given point of time. According to studies, more than ten million Americans including men, women and kids suffer from depression at a given point of time.
Incidence of depression means the annual rate of diagnosis of depression and prevalence of depression means the number of people suffering from depression at any given point of time. Incidence and depression prevalence statistics are the results of various researches and studies, these stats are helpful in approximating the depression occurrence in people yearly. These stats are not completely concise, but are good enough to measure the prevalence and incidences of depression at a given point of time. The stats for both incidence and prevalence may differ from each other, as the incidences of a disease can be higher compared with the prevalence of the disease. For example A patient might get diagnosed with depression but its not necessary that the diagnose will result in prevalence. Prevalence stats of various forms of depression as per various researches and studies performed on Americans are:
According to National institute of mental health (NIMH), approximately 6.5% of women suffer from major depressive disorder at a given point of time in America, and comparatively 3.3% of male population suffers major depressive disorder at any given point of time. As per studies performed by National institute of Mental health overall approximately 5.3% adults and 4% adolescents suffer from serious depression annually. The prevalence of postpartum depression is approximately 1 out of 679 people, which is very low as compared to other forms of depression.
The prevalence of dysthymia a mild form of depression is approximately 1 out of 24 people or 4.01%, out of which 1.6% percent affected population is adult population, as per the National institute of mental health. The prevalence rate of depression in Americans is 5.30% according to various researches and studies by NIMH. Prevalence of depression is country specific or region specific. Prevalence of depression may differ from country to country or region to region, it would be wrong to go by the statistics of one country. Incidences of depression are calculated according to the estimated new cases of depression diagnosed by specialists. Those cases are not considered that have already been diagnosed and getting treated while calculating incidences of depression.
The incidence and prevalence data for depression may have some problems. Such as, the source of data is not clear at times and the estimation of data is an approximation. Problems with the way of calculating stats, some resources rely on surveys and some of them are based on experimental studies. Experimental studies give accurate stats whereas survey over the phone or any other source does not give accurate data. Stats might be of different years, different regions or countries. So it is not easy to say that the stats for both incidence and prevalence of depression are accurate.
