1 Population’s health

Life expectancy in Switzerland is one of the highest in the world. Between 1990 and 2022, it increased by 7.6 years among men and by 4.6 years among women. Healthy life expectancy roughly stands at around age 71. In terms of this measure, the gap between men and women is small.   

86% of men and 84% of women assessed their state of health as good or very good. With age, these proportions decrease and the general health worsens. From the age of 65, half of the population suffers from long-standing health problems.

Limitations in activities people usually do, as well as functional limitations affecting eyesight, hearing and speech, increase with age. In 2022, 8% of persons aged 65 or over had been severely limited in their activities for at least six months. Approximately 1 572 000 persons, or 22% of the population, are considered to be disabled under the Disability Discrimination Act, of whom 339 000 are severely limited in activities people usually do.

The vast majority of the population say that they experience posi­tive emotions far more often rather than negative emotions: 84% of the population say that they are happy, while only 3% say they feel down or depressed. 90% of the population also have sufficient social support to cope with life’s difficulties. 18% of the population, however, show signs of medium (14%) or high psychological distress (4%). Depression is the most common mental disorder. 8% of men and 12% of women suffered from moderate to serious depression in 2022. Young people aged 15 to 24 are the most frequently affected.

In 2022, 8% of the population were in treatment for psychological problems and 9% used at least one psychotropic drug (antidepressant, sleeping pill, sedative). Women use psychotropic drugs more often than men, and older people significantly more than younger people. In addition, just over 1% of persons in the age group 15 – 24 years took medication for attention disorders in 2022.

In 2022, 111 840 hospitalisations due to mental and behavioural disorders were recorded. It is common for the same person to be hospitalised several times for different mental or behavioural disorders. Mood disorders (mainly depression) are the most frequent cause (30%) of these hospitalisations. The share of hospitalisations due to mental disorders, such as schizophrenia, is 14%. Men in the 25–44 age group are most frequently affected by these disorders. Disorders related to the consumption of alcohol and other psycho­active substances are the cause of 22% of these hospitalisations; men are affected 2.0 times as often as women.

1.3 Cardiovascular disease and diabetes

Cardiovascular diseases are the first most common cause of death – and the third most common cause of hospitalisation. Since 2002, the number of hospitalisations for cardiovascular diseases has increased by 18% very likely as a result of increasing population numbers and an ageing population. Over the same period, the number of deaths caused by these illnesses however has fallen by 14%. In 2022, 19 534 people (two thirds of whom were men) suffered an acute myocardial infarction and 2250 people died from this. The respective numbers for strokes are 21 797 (slightly over half of which are men) and 2535.   

The share of persons suffering from hypertension was 20% in 2022. Men are more affected than women until the age of 75. From the age of 75 onwards, more than half the population has blood pressure that is too high. The share of people whose cholesterol level was too high was 15% in 2022.

In 2022, 6% of men and 4% had diabetes. People with a low level of education are almost three times as likely to suffer from diabetes as those with a high-level education (11% compared with 4%).

More than 45 000 new cases of cancer are diagnosed every year. More than one in five will develop a cancer before the age of 70. Men are more affected by cancer and die from cancer more often than women do. During the period under observation (1991–2020), the rate of new cases increased up to 2005 among men, then fell. Among women, the rate of new cases rose up to 2015 and tended to diminish for the last period observed.   

Prostate cancer is the most common cancer among men but it is cancer of the lung, bronchi and trachea that cause the most deaths. Breast cancer is the most common cancer among women. Along with lung cancer, it is also responsible for the most deaths.

Every year between 2016 and 2020, about 246 children aged 14 and under got cancer and about 25 died from this disease. Leukaemia (30%) and tumours of the central nervous system (24%) are the two most common types of cancer in children.

1.5 Infectious diseases

The number of new cases of infection with the HIV virus has fallen sharply since 2009. Other cases of other sexually transmitted diseases are not decreasing.

The main infectious diseases transmitted by ticks are Lyme disease (8000 to 15 000 cases per year) and meningoencephalitis (388 cases in 2022). The latter affects men about 1.5 times more often than women.

The number of new cases of tuberculosis has decreased over the past ten years; the majority of cases occur in people of foreign origin who come from a country with a high incidence of tuberculosis.

Until the appearance of COVID-19, influenza was the main seasonal infectious disease. It may require hospitalisation, especially among older persons (3850 cases per year on average from 2018 to 2022). Winters with strong influenza epidemics are marked by excess mortality.

Diseases of the respiratory system can be chronic or acute. Among chronic diseases, 6% of the population suffered from asthma in 2022 and 2.5% from a chronic obstructive bronchial or pulmonary disease. Asthma is more common in people aged under 35. In contrast, people aged at least 75 are most affected by chronic obstructive disease. The latter are the cause of more hospitalisations than asthma and of a greater number of deaths (1958 compared with 68 in 2022).

Among acute diseases of the respiratory system, pneumonia is the cause of the greatest number of people hospitalised (28 644 in 2022) and deaths (1312 in 2022). Acute respiratory disease is extremely seasonal in nature, leading to increased take up of health care services during the winter months.

Back pains or kidney pains are the most common physical problems: 45% of the population suffer from these. The proportion of the popu­lation affected by osteoarthritis or arthritis increases sharply with age, reaching 42% from the age of 75.

Musculoskeletal disorders are the second most common cause for hospitalisation after traumatic injuries. Disorders of the limb joints (osteoarthritis, arthritis) and back problems are the reasons for 53% and 23% of these hospitalisations. The use of protheses is sometimes necessary. In 2022, 28 452 persons were hospitalised for hip replacements. This is 36% more than in 2010. Knee protheses are slightly less common (25 288).

The average age of mothers at maternity has continued to increase since the 1970s. In 2022, the share of women under the age of 30 who had given birth was 25% compared with 70% in 1970. 95% of births take place at the hospital and a third of deliveries are by caesarean. The rate of caesareans vary by up to 100% depending on the region.

311 infants and children under the age of one died in 2022. This corresponds to a rate of 3.8 deaths per thousand live births. Almost 60% of these deaths occurred in the 24 hours following birth. Above all infant deaths affect children with a very low birth weight or those born very prematurely. The same year 359 stillbirths were registered.

3.0% of children were born as twins and 0.07% as triplets. 2487 children were born as a result of a treatment in 2021 using assisted reproduction technology by in-vitro fertilisation, i. e. 2.8% of live births.

In 2022, 74 425 deaths were recorded. This was 5% more than in 2021. COVID-19 caused 5.5% of deaths in 2022, placing it fifth among causes of death, behind respiratory disease (6.1%). The graphic shows the main causes of death which vary greatly by age group. The areas are proportional to the absolute number of deaths.

Perinatal causes of death predominate in the first year of life, followed by congenital diseases. Although death from the age of 1 to 14 is uncommon, there are many different causes. The majority of deaths from the age of 15 to roughly 45 are caused by accidents and suicide. After this age, the most common cause of death is cancer. From around the age of 80 this is overtaken by cardiovascular diseases. In 2020, it was observed that COVID-19 related deaths also varied by age: the percentage of people who died from COVID-19 was greater among those aged 65 and over than among younger people.

958 people committed suicide in 2022. The vast majority were men (73%) and almost half (44%) were under 55. In the same year, the number of assisted suicides was 1594. Women account for the majority (59%) and almost nine out of ten (88%) persons seeking assisted suicide are over 64. Assisted suicide is mostly requested by persons suffering from serious and incurable diseases such as cancer (39%) or neurodegenerative diseases (13%). From the age of 65, assisted suicides outnumber suicides.
