Adolescent health and well-being
Technology, immigration and other factors are drastically changing the health needs of adolescents.
The world is now home to the largest cohort of adolescents in history – 1.2 billion people between the ages of 10 and 19. How they develop and grow has implications that reverberate across generations.
Just some of the factors that impact the development of today’s adolescents include social media, urbanization, unhealthy diets, armed conflict, climate change and migration.
While adolescents have a better chance of improving their health and well-being now more than ever, an estimated 1.2 million still die each year – mostly from preventable causes. Many lack access to the essential information, quality services and protective environments they need to stay healthy and well.
An estimated 1.2 million adolescents die every year – mostly from preventable causes.
Diseases like malaria and cholera still take the lives of adolescents worldwide, especially in humanitarian settings, where health supplies and services, and water, sanitation and hygiene facilities are scarce. In low- and middle-income countries, home to 90 per cent of today’s adolescents, young people are among the populations most at risk of contracting HIV, and the group least likely to have access to treatment. Adolescents are the only age group for whom AIDS deaths are on the rise.
Increasingly unhealthy diets, inactive lifestyles, mental ill-health, alcohol and tobacco use, and environmental risks such as air pollution are some of the most prominent issues facing adolescents today.
For adolescent girls, the onset of puberty brings additional threats. Poverty and discriminatory social and gender norms can restrict girls’ life choices and exclude them from educational, social and economic opportunities. Each year, an estimated 23 million adolescent girls become pregnant. Maternal mortality – in many cases linked to child marriage – is a leading cause of death for girls aged 15–19. Female genital mutilation can also cause life-threatening health complications.
Self-harm is a leading cause of death for adolescents between the ages of 15 and 19.
Mental health conditions also take an immense toll. Over half of these conditions surface during the second decade, with depression emerging as a leading cause of adolescent illness and disability. For 15- to 19-year-olds worldwide, self-harm is a top killer.
What’s more, some 70 per cent of premature deaths are associated with behaviours, like smoking or binge drinking, that arise during adolescence. Most are linked to non-communicable diseases, including diabetes and pollution-related conditions.
Around the world, UNICEF partners with adolescents to improve the policies, programmes and services that affect their health and well-being. We work with Governments in health and other areas – like education; nutrition; gender; child protection; HIV and AIDS; and water, sanitation and hygiene – to increase investments and help countries develop comprehensive plans that address the needs of all adolescents, especially the most marginalized. Our efforts:
- Fight communicable diseases, like malaria and diarrhoeal diseases.
- Support HIV and AIDS prevention programmes tailored to local needs.
- Strengthen gender-responsive health services through programmes that promote gender equality, reduce stigma and discrimination, and provide adolescents with the information they need to make decisions that affect their own health, including their sexual and reproductive health.
- Meet the menstrual health and hygiene needs of adolescent girls, including by preventing and responding to early and unintended pregnancy, conducting evidence-based advocacy to address stigma and providing menstrual hygiene supplies and facilities – especially in emergency settings.
- Promote mental well-being and address mental health conditions through global advocacy, awareness-raising, and evidence-building to support the implementation and scale-up of effective interventions.
- Promote good nutrition, including by providing counseling and other services that support healthy eating and physical activity.
- Prevent and respond to non-communicable diseases by promoting healthy behaviours, the prevention of substance use, increased physical activity, and youth-led policy action. We also help reduce the risk of cervical cancer through Human Papillomavirus (HPV) vaccines.
- Prevent and respond to violence at home, in school and throughout communities, and protect adolescents from unintended injuries.

This package of guidance, tools, activities and supplies aims to promote positive outcomes for adolescents’ psychological well-being. It was developed through human centered-design processes with adolescents aged 10-19 and focuses on developing their skills to express themselves, participate in decisions that affect them, and contribute to positive change in their communities.
