Non-communicable diseases (NCDs) such as heart disease, diabetes and dementia accounted for 74 per cent of global deaths in 2023, up from 58 per cent in 2000, according to the latest estimates released by the World Health Organisation (WHO).

The findings, contained in the WHO’s latest Global Health Estimates released on Friday, show that although global life expectancy has largely recovered from the disruption caused by the COVID-19 pandemic, the world’s disease burden is increasingly shifting towards chronic illnesses and mental health conditions.

According to the report, global life expectancy reached 73.3 years in 2023, almost returning to the 73.4 years recorded in 2019 before the pandemic. However, healthy life expectancy, which measures the number of years people live in good health, recovered more slowly, reaching 62.8 years in 2023, still 0.4 years below its pre-pandemic level.

The WHO noted that eight of the world’s 10 leading causes of death were NCDs in 2023, highlighting a long-term global shift away from communicable diseases.

Cardiovascular diseases remain leading killer

The report identified cardiovascular diseases as the leading cause of death and disease burden worldwide.

It said ischaemic heart disease alone caused approximately 9.5 million deaths and 210 million disability-adjusted life years (DALYs) in 2023. DALYs measure years of healthy life lost due to illness, disability or premature death.

While many parts of the world have made significant progress in reducing the burden of ischaemic heart disease since 2000, the WHO reported rising individual-level risks in the Western Pacific and South-East Asia regions, highlighting persistent inequalities in cardiovascular health outcomes.

The organisation also reported substantial increases in the burden of other chronic diseases.

According to the report, the risk of dying from diabetes has risen considerably since 2000, particularly in South-East Asia.

Alzheimer’s disease and dementia have also become more prominent.

Dementia rose from the 19th leading cause of death globally in 2000 to the fifth in 2023, while deaths linked to the condition tripled during the period.

Mental health concerns

The WHO also highlighted the growing impact of mental health conditions on global health.

Between 2019 and 2023, the global age-standardised DALY rate increased by approximately 20 per cent for depressive disorders and nearly 45 per cent for anxiety disorders.

Together, depression and anxiety accounted for an estimated 110 million years of healthy life lost through premature death and disability in 2023.

The report further showed changing patterns in drug use disorders across regions.

Between 2000 and 2023, the WHO Region of the Americas recorded the largest increases in mortality risk and healthy life loss associated with drug use disorders, while the Western Pacific region experienced substantial declines.

Need for stronger health data systems

Speaking further on the findings, Alani Labrique, Director of WHO’s Department of Data, Digital Health, Analytics and AI, described rising life expectancy as one of public health’s greatest achievements.

However, Mr Labrique noted that the next challenge is ensuring that the additional years people live are spent in good health, while health systems adapt to the changing needs of ageing populations and the growing burden of chronic diseases.

He said the estimates provide countries with evidence on how patterns of death and disease burden are changing over time, helping governments shape health policies, strengthen digital and data infrastructure, and improve their ability to generate insights needed for targeted health interventions.

A military cardiologist, Life Ajemba, has warned that hypertension, prolonged stress, and inadequate sleep could increase the risk of cardiovascular disease among serving military personnel and veterans.

Mr Ajemba, a major-general, said hypertension remains one of the most common cardiovascular conditions among serving personnel and military retirees.

Speaking in an interview with the News Agency of Nigeria on Wednesday in Abuja, he urged military personnel and veterans to prioritise their heart health through regular medical checks, physical exercise, healthy diets and adequate rest.

He cited studies which showed that hypertension accounted for 15.31 per cent of cases treated among mainly military retirees between 2015 and 2020.

He also referenced another study which found a hypertension prevalence of 34.3 per cent among military personnel.

He noted that major risk factors included alcohol consumption, tobacco smoking, family history of cardiovascular disease and being overweight.

According to him, the demanding nature of military service could also increase cardiovascular risks due to physical stress, psychological trauma, irregular schedules and inadequate sleep.

“Military duties affect heart health through a combination of extreme physical stress, psychological trauma and environmental exposures that increase the risk of cardiovascular disease,” he said.

The military cardiologist explained that prolonged stress could increase the release of hormones such as adrenaline and cortisol, leading to increased heart rate and blood pressure.

He added that sleep deprivation, anxiety and other psychological pressures could further increase the risk of hypertension, coronary artery disease, heart attack and stroke.

Mr Ajemba stressed the importance of regular medical screening among military personnel, saying early detection could help identify silent conditions such as high blood pressure, abnormal cholesterol levels and elevated blood sugar.

He said routine medical checks could include blood pressure and heart rate monitoring, blood tests, lipid profiles, electrocardiograms (ECGs), chest X-rays, and echocardiography where necessary.

“Early detection ensures that soldiers receive treatment while remaining fit for duty, preventing medical evacuation and safeguarding their long-term health,” he said.

He also encouraged military personnel to maintain regular physical exercise, saying fitness helped reduce blood pressure, improve heart efficiency and increase resistance to operational fatigue.

Mr Ajemba, however, advised personnel to combine physical fitness with healthy eating, adequate rest and avoidance of smoking and excessive alcohol consumption.

He said maintaining a healthy lifestyle could help military personnel reduce cardiovascular risks and remain fit both during active service and after retirement.

Plateau develops five-year plan as HIV donor funding declines

The Plateau State Government and health stakeholders are developing a five-year transition plan to sustain HIV prevention, treatment and care as international donor funding for HIV programmes in Nigeria declines.

Ibinibo Chukwuemeka, Director of Health Systems Strengthening at APIN Public Health Initiatives, said the changing funding landscape would require greater government ownership and stronger measures to sustain HIV services as donor support winds down, according to a report by the Africa Independent Television (AIT) on Wednesday.

The AIDS Prevention Initiative in Nigeria, now known as APIN Public Health Initiatives, has supported HIV prevention, treatment and care in Plateau State for about 25 years.

APIN says its programmes have expanded HIV treatment access to rural and peri-urban communities, including through primary healthcare facilities.

The proposed five-year framework is expected to guide the state in assuming greater responsibility for financing and coordinating HIV services while protecting gains recorded in prevention, testing, treatment and care.

Health officials, representatives of relevant government ministries and other stakeholders are working on strategies to mitigate the impact of the anticipated reduction in donor support and prevent disruption of services for people living with HIV.

Among the measures under consideration is the integration of HIV and AIDS services into the Plateau State Health Insurance Scheme.

Stakeholders are also exploring local sources of antiretroviral drugs to help ensure uninterrupted access to treatment as external funding declines.

The proposed transition framework would provide a roadmap for sustaining HIV interventions and clarifying the responsibilities of the state government and other stakeholders in financing and delivering essential services.

The development comes amid a broader shift in Nigeria’s HIV response towards greater domestic financing and government ownership.

In June, the Federal Government launched the National HIV and AIDS Strategic Plan 2026–2030, which prioritises domestic financing, expansion of health insurance and integration of HIV services into the broader healthcare system as the country seeks to reduce dependence on donor-supported interventions.

The need for alternative financing has become more pressing as international support for HIV programmes declines.

Nigeria’s existing national HIV financing framework has also identified locally produced antiretroviral drugs and increased government investment as potential ways of reducing the country’s funding vulnerability.

Plateau has previously taken steps towards greater domestic ownership of its HIV response.

At the state’s 2025 World AIDS Day commemoration, officials disclosed that 51,370 people were living with HIV in the state as of September 2025, while 47,056 adults and 1,835 children were receiving antiretroviral therapy.

The state’s HIV response recorded 2,786 new infections and 460 HIV-related deaths in 2024, according to figures presented by the Plateau State Commissioner for Health, Nicholas Ba’amlong, in December 2025.

The success of the proposed transition will depend largely on sustained government funding, effective planning and the ability of the state health system to absorb services previously supported by external partners.

For people living with HIV, stakeholders say ensuring uninterrupted access to antiretroviral treatment and other essential services must remain central to the transition.
