The average
50% of mental health problems are established by age 14 and 75% by age 24.
Adults ages 30 to 60 tend to have a lot going on that can trigger depression: caring for children as well as aging parents, financial stress, isolation, work and relationship issues, menopause and perimenopause, dealing with major illnesses, and lots of responsibilities with no relief in sight.
For example, depression is more common among women than men. The median age of onset for depression is 32 years, meaning that half of people who will ever have a depressive episode will have had their first episode by this age.
Depression (also called major depressive disorder or clinical depression) is different. It can cause severe symptoms that affect how you feel, think, and handle daily activities, such as sleeping, eating, or working. It is an illness that can affect anyone—regardless of age, race, income, culture, or education.
Latest Federal Data Show That Young People Are More Likely Than Older Adults to Be Experiencing Symptoms of Anxiety or Depression.
In their lifetimes, about one in five Australians will experience depression. Around the world, depression affects around 300 million people.
This could mean that in most cases of depression, around 50% of the cause is genetic, and around 50% is unrelated to genes (psychological or physical factors). Or it could mean that in some cases, the tendency to become depressed is almost completely genetic, and in other cases it is not really genetic at all.
The available data suggests that age three is the lowest threshold at which childhood depression appears, but that doesn't mean it can't be identified earlier or that there aren't risk signs earlier.
Age group: Young adults ages 18 to 25 in the U.S have the highest rate of experiencing mental health conditions (30.6%), followed by those ages 26 to 49 (25.3%) and adults ages 50 and over (14.5%).
Overall, those aged 15–24 years had the highest proportion of mental or behavioural conditions (28%) while those aged 0–14 years had the lowest (13%).
Research also indicates that Gen Zers are currently the most stressed demographic of people. The American Psychological Association (APA) reports that: 90% of Gen Z experienced psychological or physical symptoms as a result of stress in the last year. ²
Researchers have known for years that women are about twice as likely to be diagnosed with depression as men, with depression being the leading cause of disease burden among women. But the differences don't end there. Depression also looks different in men.
There's no single cause of depression. It can occur for a variety of reasons and it has many different triggers. For some people, an upsetting or stressful life event, such as bereavement, divorce, illness, redundancy and job or money worries, can be the cause. Different causes can often combine to trigger depression.
Research suggests that depression doesn't spring from simply having too much or too little of certain brain chemicals. Rather, there are many possible causes of depression, including faulty mood regulation by the brain, genetic vulnerability, and stressful life events.
Anxiety disorders affect about 40 million American adults every year. Anxiety disorders also affect children and teens. About 8% of teens ages 13 to 18 have an anxiety disorder, with symptoms starting around age 6. Women are more than twice as likely as men to get an anxiety disorder in their lifetime.
Among the big five personality traits, conscientiousness is one of the two strongest predictors of depression, second only to neuroticism. Low conscientiousness leads to a more disorganized and poorly planned life, creating more stressful life circumstances and higher levels of depression.
Women are more likely to have depression than men. An estimated 3.8% of the population experience depression, including 5% of adults (4% among men and 6% among women), and 5.7% of adults older than 60 years. Approximately 280 million people in the world have depression (1).
Anxiety disorders (such as Social Phobia) are the most common type of disorder, affecting 1 in 6 (17%, or 3.3 million) Australians, followed by Affective disorders (such as Depressive Episode) (8%), and Substance Use disorders (such as Alcohol Dependence) (3. %).
Studies done by Ndetei & Vadher (1982), and Hanus Grosz (1968) have shown results of the first-born showing signs of depression than middle and youngest children.
The prevalence of past-year depression increased from 7.3% (SE=0.15) in 2015 to 8.6% (SE=0.18) in 2019 (Figure 1 ), and this monotonic increase from 2015 to 2019 remained after adjusting for sociodemographic characteristics. The prevalence of past-year depression in 2020 was 9.2% (SE=0.31).
