Ground-breaking global study shows how fitter SA bodies could lead to a fitter SA economy with potential growth of $500 million (+R7 billion) a year
The results of a ground-breaking academic study on the relationship between global economic growth and exercise, carried out by Vitality and RAND Europe, reveal significant benefits to the economy and life expectancy if physical activity levels increase globally.
The study finds that the world’s GDP would gain more than USD$100bn (£80bn or R1,5trn) each year until 2050 if people:
- walked 15 minutes more a day;
- did a slow jog of half a mile (one kilometre) a day, or;
- took 1 500 extra steps a day.
The economic improvement arises from lower mortality rates (more people alive and contributing to the economy), reduced absenteeism, and lower presenteeism driven by the impact of physical activity on mental health.
Dinesh Govender, Discovery Vitality
Chief Executive, says; “Physical inactivity, and the devastating impact it has on people’s quality of life, mortality and morbidity, is one of the key public health challenges we face. Considering that 28% of the global population are not physically active enough – 38% in South Africa – Vitality’s commitment to get people moving is more relevant than ever.”
Vitality has been successfully incentivising people to lead fitter and healthier lives and ultimately transforming the way insurance works, for over 20 years. The insurers connected by Vitality, now collectively accountable for more than 35% of the world’s individual protection market, are committed to addressing significant global challenges like inactivity. This is evidenced by the network’s commitment last year to make 100 million people 20% more active by 2025.
In South Africa specifically, Vitality has over many years designed interventions that have a tangible impact on health outcomes. Govender said; “In 2015, we pioneered a step-change in how people tracked their physical activity and health with our Vitality Active Rewards with Apple Watch benefit. Vitality members bought over 231 000 fitness devices in 2019 alone.”
Independent research has validated the efficacy of incentives combined with a behaviour-change programme. “In 2018, we released the largest study on behaviour change and incentives with RAND Europe. This study showed that members with Vitality Active Rewards and Apple Watch were 34% more active – illustrating the power of incentives designed to achieve lasting behaviour change,” Govender explains.
Similarly, the 2019 study aims to further deepen the global understanding of the real economic impact of a physically inactive population. It assesses how different physical activity improvement scenarios may affect the economy of countries up to 2050 and shows the significant influence of regular exercise on economic growth, workforce productivity and life expectancy.
Govender continues: “This ground-breaking study provides proof of the relationship between exercise, productivity, mortality and economic growth. It strengthens our resolve to continue to encourage people to Move More and become part of a global health movement.”
Some of the findings show that:
- If the physically inactive were to reach the World Health Organization’s recommended levels of exercise, employees would gain up to five additional days of productive time each year, and the global economy would grow by an estimated $220bn every year.
- Life expectancy could increase by at least 2.5 years, on average, for a person aged 40 years in this scenario.
- In addition to getting inactive people active, if those currently active increased their physical activity levels by 20%, the global economy could grow by in excess of $360bn every year; equivalent to the size of Singapore’s economy. Economic gains for the US economy would $95bn (£73bn) a year until 2050, and $11bn (£8.5bn) a year for the UK economy, in this scenario.
- Economic gains can be attributed to the reduction of premature deaths in the working age population, improving rates of sick leave and improved levels of workplace productivity associated with regular exercise.
Hans Pung, President of RAND Europe, comments on the significance of the study; “This is the first time that a multi-country macroeconomic model has been applied to the area of physical activity, facilitating a detailed assessment of the current and future implications of insufficient physical activity.”
Pung also highlights the relevance for policymakers and employers, “The study points to a significant relationship between inactivity and productivity loss, driven largely by ill-health related presenteeism. We hope that these insights will support policy makers and employers with new perspectives on how to enhance the productivity of their populations.”
For South Africa, the positive knock-on effect on the economy of an increase in physical activity, is equally acute. The RAND study shows that if South Africa succeeds in getting 20% of adults more active over the next 30 years, the average GDP will increase by USD$500 million; and if all inactive people reach the minimum WHO physical activity levels, GDP will increase by between USD$1.6 and USD$2.1 billion.

Colorectal cancer, one of the most prevalent yet preventable cancers, can develop in the colon or rectum, often starting as small polyps that can quietly become malignant if left unchecked. Dr Mpho Ramabulana, a colorectal surgeon and gastroenterologist at Netcare Akasia Hospital, underscores the life-saving power of vigilance and the importance of early detection.

The lives of millions of South Africans with a litany of rare diseases can be vastly improved, and even saved, by addressing challenges in identifying, studying and treating their conditions. With Rare Disease Day on the 28th of February 2025, the Rare Diseases Access Initiative (RDAI) is driving an evolution of the country’s healthcare, through innovative strategies to better care for over 4.2million people living with an estimated 7000 rare diseases. “As our healthcare system faces significant changes in the years ahead, it is vital that we also advocate for people living with rare diseases in South Africa, especially those with limited healthcare access,” said Kelly du Plessis, CEO of Rare Diseases South Africa (RDSA), a member of RDAI. “As part of our ongoing research and awareness efforts, RDAI has conducted an initial analysis of the incidence and prevalence of rare diseases within the country.” This research will assist in improving access to healthcare, policy development, and patient advocacy, while giving critical insight into the challenges faced by patients. “According to research, some rare diseases affect fewer than 1 in a million people, while others, such as Down syndrome, cystic fibrosis, and haemophilia, have a more recognisable prevalence,” says Dr. Helen Malherbe, RDAI lead researcher on rare disease prevalence data. “Many conditions are undetected, underdiagnosed or misdiagnosed, with too many having no information available about them at all.” The RDAI was formed in 2019 to promote a more favourable environment for those impacted by rare diseases in South Africa. Participants include Ampath, the Board of Healthcare Funders (BHF), Discovery Health, Genetic Counsellors South Africa (SASHG), the Government Employees Medical Scheme (GEMS), Health Funders Association (HFA), Medihelp, Medscheme, North-West University (NWU), Rare Diseases South Africa (RDSA), the South African Medical Association (SAMA) and The South African Medical Technology Industry Association (SAMED). The Council for Medical Schemes (CMS) participates as an observer. In the same year, Rare Disease International signed a memorandum of understanding with the World Health Organisation leading to an international rare disease policy framework. In 2021, the United Nations General Assembly moved to adopt a resolution recognising 300 million people living with rare diseases worldwide. “A general lack of awareness and delayed diagnosis remain major hurdles for those affected by rare diseases. Policymakers and healthcare stakeholders need to prioritise access to treatment, diagnosis, and support for rare disease patients,” says Bada Pharasi, CEO of IPASA, “Through this initiative, working collaboratively with stakeholders at every level of the healthcare supply chain, we can bring real and meaningful change to those affected, including family members and care givers, through smart and efficient strategies.” The globally agreed definition of a rare disease is any medical condition with a specific pattern of clinical signs, symptoms, and findings that affects fewer than or equal to 1 in 2000 persons in a population. “Most are genetic, and some are inherited and passed down in families,” Malherbe says. “Some affect only the patient’s genetic recipe, while others may be acquired during life due to infection, trauma, or environmental effects. For many, the cause is still unknown. “These conditions mainly affect children, as they are largely incurable and many are life-threatening. Some require specialised and co-ordinated care, some have limited and expensive treatment options, while others have no information or effective treatments at all,” she adds. The RDAI is calling for a patient-centred care model built on equitable access, transparency and efficiency. Naturally, this model calls for the open participation of patients, the healthcare industry, health professionals, and the Government. “The most critical elements are robust diagnosis standards, improved access to treatment, data collection and management, co-ordination of care, measurement of outcomes and ongoing collaborative research,” du Plessis says. “We need to establish rare disease advisory committees, map gaps and opportunities, establish system requirements, create a roadmap and plan a phased implementation with clear timelines.” The RDAI states that these policy development steps would be a start in quantifying the disease burden and defining standards of care. This would be followed by building and strengthening the capacity to facilitate appropriate diagnosis, treatment, continuity and data monitoring. Thoneshan Naidoo, Chief Executive Officer of the Health Funders Association noted that, “We appreciate the unique opportunity provided by RDAI which enables stakeholders across the industry to work together and identify strategies that improve equitable access to the appropriate diagnosis, treatment and healthcare services for rare disease patients, in an affordable and sustainable manner, taking account of the other pressing needs across the healthcare system.” “True innovation in healthcare is only possible through partnerships and joint advocacy efforts that raise awareness and improve access to treatment. Our long-term goal is the development of a rare diseases policy framework and guidelines for coordinated care,” says Pharasi. “Our members are united in the commitment to unlocking improved patient outcomes and improving access to services and robust health needs assessment facilities.” he concludes.
