In the UK, children and young people (roughly ages 8-25) are disproportionately affected by mental health issues, with high prevalence rates for probable mental disorders and anxiety, especially among young women, although older age groups also face significant challenges, and suicide is a leading cause of death for young people. While young people show high rates of anxiety, and young women face particular risks like eating disorders and self-harm, mental health challenges are rising across working-age adults too, with increasing NHS demand.
We take a life-course approach to mental health because good mental health begins in infancy. 20% of adolescents may experience a mental health problem in any given year. 50% of mental health problems are established by age 14 and 75% by age 24.

Whilst boomers and millennials may use the 😂 emoji, this has long since been deemed 'uncool' (or 'cheugy') by Gen Z. Instead, this has been replaced by the skull (💀) or the crying emoji (😭), dramatising the idea of 'dying with laughter'.
The report shows that while prevalence of mental health disorders can vary by sex, women are disproportionately impacted overall. Anxiety and depressive disorders are the most common types of mental health disorders among both men and women.
Globally, Ischaemic Heart Disease (Coronary Artery Disease) remains the world's biggest killer, but regionally, Dementia (including Alzheimer's) has recently become the leading cause of death in countries like Australia, surpassing heart disease for females and overall, while heart disease leads for males. Other top causes globally include stroke, respiratory infections, lung cancer, and chronic obstructive pulmonary disease (COPD).
Each year, millions of lives in the UK are impacted or cut short from the effects of three modifiable risk factors: tobacco, alcohol and overweight/obesity.
Most common causes of death
While heart disease may be the most common reason for death in all males taken together, accidents occupy the top spot for those under 45 years of age. In males between the ages of 45 and 85, it is cancer. Once men reach 85 years old, heart disease is the most common cause of death.
In 2021, a meta-analysis done on 192 studies showed that the peak age of mental illness onset was around 14 ½ years old. As we discussed above, the onset of mental illness typically occurs in young childhood and adolescence, and the study shows that different mental disorders typically onset at different ages.

The 5 C's of Mental Health provide a framework for well-being, often cited as Competence, Confidence, Connection, Character, and Caring, focusing on feeling capable, believing in oneself, nurturing relationships, living by values, and showing empathy.

For a start, the UK's population is ageing. Age is the biggest risk factor for developing dementia, so it's expected that we'll see rates of people with dementia increasing and, unfortunately, deaths from it rising too.
It basically is an app where you feed in all your health information, personal information, social information — any fact about you — and it promises to tell you your death date." Ethicist Art Caplan discusses the potential accuracy of a death clock app and the need for related health counseling.

Research on high-IQ society members showed they had much higher rates of mood disorders, ADHD, and anxiety than national averages. These mixed findings suggest intelligence affects mental health in many ways rather than through a simple direct relationship.
