Lifetime prevalence (LTP) is the proportion of individuals in a population that at some point in their life (up to the time of assessment) have experienced a "case" (e.g., a disease, a traumatic event, or, a behavior, such as committing a crime). Often, a 12-month prevalence (or some other type of "period prevalence") is provided in conjunction ...
The average lifetime prevalence found was 6.7% for MDD (with a relatively low lifetime prevalence rate in higher-quality studies, compared to the rates typically highlighted of 5–12% for men and 10–25% for women), and rates of 3.6% for dysthymia and 0.8% for Bipolar 1. [18]
Incidence is usually more useful than prevalence in understanding the disease etiology: for example, if the incidence rate of a disease in a population increases, then there is a risk factor that promotes the incidence. For example, consider a disease that takes a long time to cure and was widespread in 2002 but dissipated in 2003.

Specific phobias have a lifetime prevalence rate of 7.4% and a one-year prevalence of 5.5% according to data collected from 22 different countries. [22] The usual age of onset is childhood to adolescence. During childhood and adolescence, the incidence of new specific phobias is much higher in females than males.
A review of anxiety disorder surveys in different countries found average lifetime prevalence estimates of 16.6%, with women having higher rates on average. [151] A review of mood disorder surveys in different countries found lifetime rates of 6.7% for major depressive disorder (higher in some studies, and in women) and 0.8% for Bipolar I disorder.
The study found that an average global citizen lives 9.6 fewer healthy years than they live altogether — so, for example, someone who lived to 80 might have spent the last decade of their life ...
For example, among 15–29 year olds, suicide is much more prominent; this being the third leading cause [1] of death within this age group. Suicide is a worldwide issue which is disproportionally affecting developed countries , with 23% of the total suicide rate despite having only 17% of global population.
