Mental health disorders, malaria, and heart disease most affected by covid pandemic

Findings provide a roadmap to help strengthen health systems for future crises

2025-07-02
(Press-News.org) Disrupted care during the covid-19 pandemic led to sharp increases in other non-covid causes of illness and death, particularly mental health disorders, malaria in young children, and stroke and heart disease in older adults, finds a study published by The BMJ today.

For example, new cases of depressive disorders rose by 23% in 5-14 year-olds and malaria deaths rose by 14% in children under five years old from 2020-2021.

The researchers say future responses to potential pandemics or other public health emergencies of international concern “must extend beyond infection control to address long term, syndemic health impacts.”

Most healthcare services were severely affected during the pandemic, hindering efforts to prevent and control many conditions. Yet an in-depth analysis of the pandemic's impact on other causes of illness and death is still needed.

To address this, researchers in China used data from the Global Burden of Disease Study 2021 to simulate the burden of 174 health conditions in 2020 and 2021 across various regions, age groups, and sexes.

A total of 204 countries and territories were included in the analysis. The main measures of interest were incidence (number of new cases), prevalence (number of people living with a condition), deaths, and disability adjusted life years (DALYs) - a combined measure of quantity and quality of life.

Depressive and anxiety disorders, along with malaria, were the most notably affected, with a significant rise in disease burden compared with other causes.

For example, age standardised DALY rates for malaria rose by 12% (to 98 per 100,000). DALY rates for depressive and anxiety disorders also rose by 12% (to 83 per 100,000) and 14% (to 74 per 100,000), respectively, especially among females.

Age standardised incidence and prevalence rates for depressive disorders rose by 14% (to 618 per 100,000) and 10% (to 414 per 100,000), respectively, while anxiety disorders saw a 15% rise (to 102 and 628 per 100,000).

Prevalence rates for heart disease also saw notable increases, particularly among individuals aged 70 and above (169 per 100,000 for ischaemic heart disease and 27 per 100,000 for stroke). 

There was also a significant (12%) increase in the age standardised death rate due to malaria, particularly among children under five years old in the African region.

The researchers acknowledge that their methods may not fully capture the complexity and variation of pandemic-related disruptions, and say factors such as uneven quality of data across regions, potential underreporting, and delayed diagnoses during the pandemic, may have affected the accuracy of their results.

However, they say their analysis offers broader scope than previous studies and provides actionable, policy relevant recommendations to improve health system preparedness.

As such, they conclude: “These findings underscore the urgent need to strengthen health system resilience, enhance integrated surveillance, and adopt syndemic-informed strategies to support equitable preparedness for future public health emergencies.”

This study highlights how data can guide smarter recovery to ensure that future health crises disrupt lives less and afflict populations more evenly, say researchers in a linked editorial.

By integrating these insights into post-pandemic plans, countries can improve resilience, they write. Concrete steps include allocating budgets for essential services in emergencies, reinforcing primary health care, expanding disease surveillance networks, and prioritising universal health coverage with a focus on disadvantaged or marginalised communities.

“Ultimately, recognising and planning for the pandemic’s indirect toll will save lives and leave health systems stronger and fairer for future public health emergencies,” they conclude.

Green transition will boost UK productivity

2025-07-02
The green transition will boost productivity across the UK economy, new research suggests. Researchers analysed the impacts of the low-carbon transition in power, transport and heating. With renewable energy now cheaper than fossil fuels in most of the world – and still getting cheaper – the findings show these three industries benefit directly from the transition. But the far larger knock-on effect is an economy-wide productivity boost, as all businesses gain from cheaper power, transport and heating. The research team – led by the universities of Exeter and Manchester – warn that this boost depends on cheaper ...

Billions voted in 2024, but major new report exposes cracks in global democracy

2025-07-02
A new report from the University of East Anglia has raised concerns about the state of democracy around the world during 2024’s ‘Super Cycle’ of elections. Described by Time Magazine as the ‘Year of Elections’, 2024 saw 1.6 billion people head to the polls across 74 national elections in 62 countries - an unprecedented concentration of democratic activity in a single year. But a global report from the Electoral Integrity Project, released today, paints a mixed and often troubling picture of how those ...

Researchers find “forever chemicals” impact the developing male brain

2025-07-02
“Forever chemicals” or per- and polyfluoroalkyl substances (PFAS) have been widely used in consumer and industrial products for the better part of a century, but do not break down in the natural environment. One PFAS, perfluorohexanoic acid or PFHxA, is made up of a shorter chain of molecules and is thought to have less of an impact on human health. New research from the Del Monte Institute for Neuroscience at the University of Rochester suggests otherwise, finding that early life exposure to PFHxA may increase anxiety-related behaviors and memory deficits in male ...

Quantum leap in precision sensing across technologies

Quantum sensing:  Researchers at the Niels Bohr Institute, University of Copenhagen, have developed a tunable system that paves the way for more accurate sensing in a variety of technologies, including biomedical diagnostics. The potential range of technologies is large, stretching from the largest scales – detecting gravitational waves in space over environmental monitoring to the tiny fluctuations in our own bodies – biomedical sensing for imaging and diagnostics in e.g. magnetic scanners. The result is now published in Nature. Quantum limit – this is where it gets really tricky Optical sensing ...

Upgrading biocrude oil into sustainable aviation fuel using zeolite-supported iron-molybdenum carbide nanocatalysts

2025-07-02
Wet wastes, including food waste and biomass, are promising candidates for sustainable aviation fuel (SAF) production due to their triglyceride content, which can be converted into biocrude via hydrothermal liquefaction (HTL). SAF precursors must meet criteria derived from conventional fuels (e.g. Jet A), including complete oxygen removal to prevent jet engine corrosion and a higher heating value (HHV) close to Jet A. Currently, no HTL-derived biocrude meets these. This study, with contributions from researchers at the Center for Advanced Bioenergy and Bioproducts Innovation ...

For effective science communication, ‘just the facts’ isn’t good enough

2025-07-02
In a new communications landscape that feasts on polarization, the science community needs to rethink how it engages society in scientific discovery, controversy and policy. The authors of a report in this week’s Proceedings of the National Academies of Science (PNAS) argue that the standard communication model of disseminating the facts and assuming “the truth will prevail” is increasingly falling on deaf ears.  Instead, the science community needs to create a “collaboration model” that invites more public conversations, incorporates personal morals and values, creates a level playing field for input, and embraces uncertainty.
