Investing in adolescent health is critical for SA’s future, as closing gaps now drives long-term wellbeing, equity, and economic growth.
Each year on World Health Day, we are called to reflect on what Health for All truly means in practice. While early childhood and ageing populations rightly command attention, the group between these two life stages, adolescents, remains persistently overlooked in policy, planning, and investment.
In South Africa, adolescents aged 10–19 account for nearly one in five people, more than ten million young citizens. Yet they exist in a structural blind spot; too old for paediatric care, too young to be adequately prioritised within adult-oriented health services. From a health systems and leadership perspective, this is not simply an equity gap. It is a strategic failure.
Every adult was once an adolescent; navigating identity, ambition, risk, and decision-making. Adolescence is a period of rapid physical, emotional, and social development, during which experiences set trajectories for lifelong health, productivity, and wellbeing. Neglect at this stage reverberates for decades; across labour markets, healthcare systems, and social cohesion.
South Africa’s adolescents are growing up in a country of striking diversity and inequality. Where a young person is born shapes the quality of schooling they receive, the safety of their community, their exposure to digital spaces, and their access to health information and support. These contexts in turn determine who is protected from risk and who is exposed to it. For those of us trained in systems thinking, this should sound familiar: outcomes are shaped less by individual choices alone than by the environments in which those choices are made.
Health services reflect many of these broader disparities. Although urban areas appear better resourced on paper, access within cities is far from equal. Historical spatial planning continues to determine where clinics and hospitals are located, while townships and peri-urban settlements expand faster than health infrastructure can keep pace. Geography remains a powerful predictor of adolescent access to care.
Adolescents also encounter a structural disconnect within the healthcare system itself. In many settings, paediatric services end around age 13, well before adolescence does. Young people are expected to transition abruptly into adult services that were never designed for their developmental stage. The result is predictable; disengagement, missed prevention opportunities, and late presentation for care. In any other sector, we would describe this as a failure of continuity and customer-centered design. Yet in healthcare, it is often accepted as normal.
At the same time, today’s adolescents are navigating pressures unlike those faced by previous generations. Global digital connectivity accelerates trends in identity, behaviour, and risk. While teenagers strive to be unique and independent, peer norms frequently converge; shaping shared patterns around relationships, substance use, and health-seeking behaviour. Vulnerability and opportunity coexist, amplified by technology and social media.
These dynamics intersect with stark health realities in South Africa. Adolescent pregnancy remains common, with more than 117,000 girls aged 10–19 giving birth in the most recent financial year. Adolescent girls and young women continue to shoulder a disproportionate burden of HIV infections. Mental health challenges among adolescents are rising, with implications for educational attainment, economic participation, and long-term wellbeing.
For business-school alumni and healthcare leaders, this should prompt a familiar conclusion; risk left unaddressed upstream becomes cost downstream. Poor adolescent health outcomes drive higher spending on avoidable complications, constrain future workforce participation, and entrench intergenerational inequality. Conversely, timely investment yields compounding returns.
It is normal and developmentally appropriate for adolescents to test boundaries and embrace a sense of invincibility. The role of adults and institutions is not to suppress this exploration, but to guide it. Adolescent-responsive health services, safe spaces for learning, accurate information, and trusted relationships help young people navigate risk without stifling creativity, ambition, or individuality. This guidance builds resilience and supports healthier transitions into adulthood.
Evidence consistently shows that investing in adolescent health improves school completion, employment prospects, and long-term health outcomes. From a strategic perspective, adolescence represents one of the highest-return investment windows in the life course. Yet it remains under-financed and under-prioritised relative to its long-term impact.
Our adolescents form a bridge between the systems we manage today and the society we hope to lead tomorrow. Neglecting this stage undermines human capital development, strains future health systems, and weakens economic resilience. Thoughtful, coordinated investment, across health, education, and social protection, strengthens the foundations of a more equitable and prosperous South Africa.
On this World Health Day, achieving Health for All requires more than moral commitment. It requires strategic leadership and long-term vision. Healthy adolescents do not emerge by chance; they are built through deliberate choices.
Healthy adolescents become healthy societies.
Our future depends on what we choose to build with them today.
