Beyond sugarcane fields and dreamy beaches, Mauritius secures first place in mobile connectivity Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Mauritius's rise as African leader of mobile networks Last updated: 08/06/25, 11:12 Published: 05/06/25, 07:00 Beyond sugarcane fields and dreamy beaches, Mauritius secures first place in mobile connectivity Background: GSMA ranking In the bustling capital city of Port Louis, commuters check the latest news updates using mobile data on their phones. Across the busy, connecting streets, a handful of tourists video call their family back home, asking them what souvenirs they would like- also on mobile data. Apart from idyllic holiday scenes and solid sugar exports, the island nation of Mauritius has recently become number one in Africa for mobile connectivity- as scored by the Global System for Mobile Communications Association (GSMA). The small island is now at the forefront of telecommunication development, with the increasing rollout of 5G networks. How did this touristic country become a leader in mobile connectivity? On the 13th of August 2024, the GSMA announced its yearly index for mobile connectivity. The GSMA looks at 41 African countries and ranks them based on: internet accessibility, prices of mobile devices, relevant services and political environments. Scoring 62.7 points out of the possible 100, Mauritius took the first spot, in front of South Africa. This result also places the island country 76th in the world. Remarkably, this is the third consecutive year that Mauritius is leading in mobile connectivity in Africa. Moreover Mauritius, with a population of 1.26 million, boasts an average of 1.7 phones per person, compared to only 1.2 phones per person in the US (according to 2023 data). Connecting the island: 5G is nearly everywhere Three companies provide mobile phone networks on Mauritius island: Emtel, MTML (Chili) and state-owned My.t. At present, 5G is widely available in Mauritius, thanks to Emtel supplying it to approximately 80% of the island for both residential and commercial usage. Though Emtel is the biggest network in the country, My.t is the most popular provider currently, and it also offers 5G to its users. A closer look at 4G and 5G 3G (and 3G High-Speed Packet Access, HSPA), 4G (Long Term Evolution, LTE) and 5G are wireless mobile networks, where the ‘G’ in these networks means ‘generation’ and indicates the strength of the signal on the mobile device. Hence, each mobile network is an improvement since the last generation of network. These mobile networks aim for high quality, reliable communication, and are based on radio signals. Each generation has evolved to achieve this. Table 1 compares the differences between all of these networks. The original 1G network from 1979 used analogue radio signals, while subsequent network generations use digital radio signals. Table 1: A comparison of 2G, 3G, 4G and 5G mobile networks 2G 3G HSPA+ 4G LTE 5G Speed 64Kbps 8Mbps 50Mbps 10Gbps Bandwidth 30- 200 kHz 15- 20 MHz 100 MHz 30- 300 GHz Features Better quality video calls than before Can send and receive larger emails Higher speeds and capacities Much faster speeds and capacities; high resolution video streaming SMS and MMS Larger capacities Low cost per bit Low latency Interactive multimedia, voice, video Allows remote control of operations e.g. vehicles, robots, medical procedures It is evident from Table 1 that not only have speeds and capacities increased with each generation, but new features have also been implemented such as video calls, interactive multimedia, streaming, and remote control of operations. Introduced in 2019, 5G is thought to be the most ambitious mobile phone network- almost revolutionary in its benefits since 1G. Usually, mobile carriers operate on a 4G LTE and 5G coexistence. This means that 5G phones can switch to 4G if 5G isn’t available in the region. Top of the tower- how? Since the 5G rollout in 2021, Mauritius has been enjoying the larger capacities and speeds of the network. The same question arises: how did this touristic country become a leader in mobile connectivity? There are several factors: - Tourist hotspot - Government initiatives - Improving local infrastructure - General advancements in mobile network technologies - High penetration rates and mobile ownership - Increasing number of connections - Geography Each factor will be considered in turn. Factor 1- Tourist hotspot Every year, Mauritius attracts visitors far and wide to enjoy its mesmerising beaches, luscious escapes and tantalising wildlife. Therefore, over time, mobile network technology has had to improve to meet the communicative needs of tourists. Put differently, tourism significantly supports the telecom industry on the island. Factor 2- Government initiatives As well as providing free, public WiFi hotspots around the island, the government is committed to bridging the digital divide and increasing access to all of its population. Thus, it was announced that, eligible citizens between the ages of 18 and 25 will receive a free, monthly mobile data package (with 4G and 5G capabilities)- starting from the 1st of September 2024. It is an endeavour to include young people in the government’s digital plans, i.e. digital inclusion. Factor 3- Improvements in local infrastructure In recent years, My.t and EmTel have been upgrading their equipment to ensure better coverage and access to 5G in the country. Infrastructure must have improved so that the three mobile operators on the island were granted the license for 5G rollout in June 2021. The current goal is to fully expand 5G coverage in Mauritius. Factor 4- General advancements in mobile network technologies Since its inception in 2019, 5G has had a profound impact on consumers around the globe with its low latency, high resolution streaming, and insanely high speeds and capacities. This pioneering mobile network has rolled out to millions of people, including the citizens of Mauritius island. The government has utilised this new technology to empower its people and pave a way for the country to become a leader in mobile connectivity. Factor 5- High penetration rates and mobile ownership Early 2025 data shows that the East African nation has over 2.1 million active mobile connections, when its population is half of that, a mere 1.261 million. (More mobile connections is not a usual thing as people may have separate connections for personal and work use, for example. Embedded SIMs – eSIMs- have made this possible recently). With this statistic, Mauritius has a high degree of mobile ownership and network connection density. Factor 6- An increase in the number of connections Another recent event is that the number of mobile connections in the nation has been increasing gradually: between 2024 and 2025, the number has increased by 1.9%. Factor 7- Geography It is known that less land- especially less rural land- makes deployment of cell phone towers and installation of masts much easier. Therefore, spanning an area of 2,040 squared kilometres, the main island of Mauritius can enjoy adequate mobile coverage- being one of the smallest African countries. Small island, big signal. To summarise, the above factors contribute to the number one ranking in mobile connectivity for Mauritius. What does Mauritius’s rise mean for the future? If these advancements in infrastructure and technology continue on the island, then there is a brighter outlook for the future. 5G coverage in Mauritius is on its way to completion, ensuring all districts have access to the latest mobile network. Geography, government initiatives, improvements in infrastructure by mobile operators, high number of mobile connections and ownership, are some of the factors that enabled 5G rollout in Mauritius in the first instance. Mauritius is leading by example to the other countries in Africa and is additionally performing well on the global stage for mobile networks. This small island country, usually known for its exotic sights and sugarcane landscape, is quickly overtaking its African neighbours in the race to become the leader in mobile phone connectivity.

Rising temperatures can affect brain health Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link The Brain-Climate Connection: The Hidden Impact of Rising Temperatures 19/06/25, 10:14 Last updated: Published: 24/05/23, 09:55 Rising temperatures can affect brain health Global warming is not only disrupting ecosystems, affecting the food we eat and the air we breathe, but it’s also impacting our neurological health. According to the 2022 Global Climate Report from NOAA National Centers for Environmental Information , 2022 was the sixth warmest year since 1880. To understand this better, let’s start with the basics. The brain is made up of billions of tiny cells called neurons that communicate with each other by generating electrochemical signals. Think of neurons as small batteries capable of producing electricity when triggered by electrically charged chemicals, called ions. When a neuron is at rest, so when it’s not transmitting an electrical signal, it maintains a negative charge inside compared to the outside. This difference in charge is created by the selective movement of ions across the neuron’s membrane through ion channels and pumps. The resting membrane potential of a neuron is typically around -70 millivolts (mV). When a neuron needs to send information, it generates electrical activity called action potential , which causes the electrical charge to become less negative and closer to zero. To trigger a full-sized action potential, the electrical charge needs to reach a threshold of approximately -55 mV. If the charge reaches this threshold, a full-sized action potential is triggered and the neuron will send a signal down to other neurons. However, if the electrical charge does not reach this threshold, the neuron will not send a signal at all. This is known as the “ALL OR NONE” principle. The action potential is a crucial part of the neuron’s communication process, as it allows the neuron to send signals quickly and efficiently to other neurons. But here’s the catch: temperature fluctuations can affect the ion channels that generate and propagate action potentials, which are critical for the neuron’s communication process. It turns out that an increase in temperature can influence the generation , speed , and duration of action potentials. But that’s not all! Hotter temperatures can trigger seizures in individuals with epilepsy or a history of seizures. One of the most concerning findings from scientific research is that climate change, among other factors, may contribute to an increase in seizure severity and frequency, as well as the development of cerebrovascular and neurodegenerative diseases, such as strokes or dementia . Triggering stress and sleep deprivation, heat waves can also exacerbate the symptoms of such pre-existing disorders. The good news is that we can take action to address the direct impact of climate change on our planet and health. Joining initiatives like Climatematch Academy (CMA) , a 2-week interactive online summer school, can help you learn more about climate science and become part of a global community that is working towards a more sustainable future. CMA is an all-volunteer organization run by dozens of science enthusiasts. It aims at introducing computational methods for climate science taking advantage of available open-source tools and datasets to make science accessible to students worldwide. This is your chance to learn cutting-edge techniques from climate science experts and make a difference in the world, ensuring a brighter future for ourselves and future generations.

The specific research that was recognised for a Nobel Prize in Physics was the discovery of radioactivity. Radioactivity is the spontaneous emission of energy, in the form of radiation, a term that Curie herself coined. Marie Curie researched whether uranium, a weakly radioactive element, was found in other materials. She then analysed pitchblende, Go Back Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link The Women who have won the Nobel Prize in Physics Last updated: 13/11/24 Published: 01/03/23 March is International Women’s month, so it seems like the perfect time to celebrate the women who have been awarded Nobel Prizes in Physics. There have only been a total of four women to receive this prestigious award, namely Marie Curie, Maria Goeppert Mayer, Donna Strickland, and Andrea Ghez. This article will detail the research each woman did to achieve the Nobel Prize, as well as the context of their discoveries. Marie Curie (1903) Arguably the most famous of these Nobel Prize winners, Marie Curie won her award for research on radioactive phenomena. Curie received half the Nobel Prize for Physics, shared with her husband, but at first, the committee had only intended to award it to him. This was the first Nobel Prize for Physics ever awarded to a woman. The specific research that was recognised for a Nobel Prize in Physics was the discovery of radioactivity. Radioactivity is the spontaneous emission of energy, in the form of radiation, a term that Curie herself coined. Marie Curie researched whether uranium, a weakly radioactive element, was found in other materials. She then analysed pitchblende, a mineral made partially of uranium but had a higher amount of radiation. Curie investigated other elements that pitchblende could be made up of and, as a result of this, discovered new elements: polonium and radium. Following this, she had ambitions of obtaining pure radium, and following this achievement, she was awarded the Nobel Prize in Physics in 1903. Maria Goeppert Mayer (1963) 60 years after Marie Curie was awarded her Nobel Prize for Physics, Maria Goeppert Mayer became the second female recipient. She received the Prize for her work in 1963 on the nuclear shell model of the atomic nucleus. Goeppert Mayer shared her award with two other physicists who came to the same conclusion as her. The nuclear shell model describes the exact makeup of the atomic nucleus, through the exact numbers of protons and neutrons. Maria Goeppert Mayer’s mathematical work on this model described why there are certain amounts of neutrons and protons in stable atoms. She beautifully described the model in terms of waltzers dancing and spinning in circles. Donna Strickland (2018) The next female Nobel Prize in Physics award winner wouldn’t be until another half-century later, with Donna Strickland. Strickland was awarded the Prize for her work on chirped pulse amplification and its applications. Although the research itself was published in 1985, she didn’t receive the award until 2018. Chirped pulse amplification (CPA) is a technique that takes a very short laser pulse (a light flash) and makes it brighter. The technique is useful for making extremely precise cuts, so is used for many laser-related applications, such as laser eye surgery. The wide range of uses CPA has in medicine makes this an important discovery for physics which led to Strickland being awarded the Nobel Prize award. Andrea Ghez (2020) The result of the work of Andrea Ghez, the fourth female Nobel Prize in Physics recipient, may be the most exciting conclusion of the research described in this article. Ghez won the award for her role in discovering a black hole in the centre of our galaxy. A black hole is a very dense, compact object with gravity so strong that not even light can escape it. Until recently, physicists have not been able to visually observe black holes but instead can detect them by looking at how other objects, such as stars, behave around one. Andrea Ghez and her team used the movement of Sagittarius A* to prove that there was a black hole in the centre of the Milky Way.

Non-cell-autonomous cancer progression from chromosomal instability Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Immune signals initiated by chromosomal instability lead to metastasis 09/07/25, 14:23 Last updated: Published: 14/09/24, 21:17 Non-cell-autonomous cancer progression from chromosomal instability Unravelling the intricate relationship between immune cells and cancer cells through STING pathway rewiring. Introduction Chromosomal instability ( CIN ) has long been recognised as a prominent feature of advanced cancers. However, recent research has shed light on the intricate connection between CIN and the STING (Stimulator of Interferon Genes) pathway. Researchers at Memorial Sloan Kettering Cancer Center (MSK) and Weill Cornell Medicine conducted this ground-breaking study, which has provided fascinating insights into the function of the immune system and its interactions with cancer cells. In this article, we will delve into the findings of this study and explore the implications for future cancer treatments. STING pathway The STING pathway plays a crucial role in the response to cellular stress and the innate immunity response to DNA damage and chromosomal instability. Chromosomal instability refers to the increased rate of chromosomal aberrations, such as mutations, rearrangements, and aneuploidy, within a cell population. This instability can lead to genomic alterations that contribute to the initiation and evolution of cancer. This pathway is activated when the presence of cytosolic DNA is detected, which can be indicative of cellular damage or infection, triggering a cascade of signalling events leading to the production of type I interferons and other inflammatory cytokines. Many recent studies have revealed an intriguing relationship between chromosomal instability and the STING pathway, including the STING pathway’s ability to be activated by the accumulation of micronuclei resulting from chromosomal instability in cancer cells. This activation can lead to the promotion of anti-tumour immunity and the suppression of tumourigenesis. The Promise and Limitations of STING Agonist Drugs STING-agonist drugs have shown great potential in preclinical studies, arousing optimism for their use in cancer therapy. However, clinical trials have yielded disappointing results, with low response rates observed in patients. Dr. Samuel Bakhoum, an assistant member at MSK, highlights the discrepancy between lab findings and clinical outcomes. Only a small fraction of patients demonstrated a partial response, leading researchers to question the underlying reasons for this disparity. The Sinister Cooperation: CIN and Immune Cells Chromosomal instability acts as a driver for cancer metastasis, enabling cancer cells to spread throughout the body. The STING pathway, specifically, is where Dr. Bakhoum's team discovered that the immune system has a significant impact on this process. The cooperation between cancer cells with CIN and immune cells is orchestrated by STING, resulting in a pro-metastatic tumour microenvironment. This finding provides a crucial understanding of why STING-agonist drugs have not been effective in clinical trials. Introducing Contact Tracing: Unravelling Cell-to-Cell Interactions Researchers utilised a newly developed tool called ContactTracing to examine cell-to-cell interactions and cellular responses within growing tumours. By analysing single-cell transcriptomic data, they gained valuable insights into the effects of CIN and STING activation. The tool's capabilities allowed them to identify patients who could still mount a robust response to STING activation, enabling the selection of better candidates for STING agonist therapy. STING Inhibition: A Potential Solution Interestingly, the study suggests that patients with high levels of CIN may actually benefit from STING inhibition rather than activation. Treatment of study mice with STING inhibitors successfully reduced metastasis in models of melanoma, breast, and colorectal cancer. These findings open up new possibilities for personalised medicine, where patients can be stratified based on their tumour's response. By identifying the subset of patients whose tumours can still mount a strong response to STING activation, doctors could select better candidates for STING agonists. This biomarker-based approach could help figure out which patients would benefit from turning on STING and which would benefit from turning it off. This could lead to more targeted and effective treatments for people with advanced cancer that is caused by chromosomal instability. Conclusion Based on the research findings, it can be concluded that chronic activation of the STING pathway, induced by CIN, promotes changes in cellular signalling that hinder anti-tumour immunity and facilitate cancer metastasis. This rewiring of downstream signalling ultimately renders STING-agonist drugs ineffective in advanced cancer patients. However, the study also suggests that STING inhibitors may benefit these patients by reducing chromosomal instability-driven metastasis. The research highlights the importance of identifying biomarkers to determine which patients would benefit from STING activation or inhibition. Overall, these findings provide valuable insights into the underlying mechanisms of cancer progression and offer potential opportunities for improved treatment strategies for patients with advanced cancer. The study shown in figure 1, analysed 39,234 single cells within the tumour microenvironment (TME), categorised by cell subtype assignment. It showed that tumour cell rates of CIN were genetically dialled-up or dialled-down. The study also showed CIN-dependent effects on differential abundance at the neighbourhood level, grouped by cell subtype and ranked by mean log2 (FC) within each cell subtype. Node opacity was scaled by the p-value.

The newest pillar of chemical research Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Not all chemists wear white coats: computational organic chemistry Last updated: 01/02/26, 19:59 Published: 01/02/26, 19:42 The newest pillar of chemical research Introduction 'Not all chemists wear white coats,' aptly describes the newest pillar of chemical research. Coined by the Royal Society of Chemistry, computational modelling has become an essential tool across all areas of traditional chemistry. As artifical intelligence (AI) and machine learning become increasingly prevalent in research, the future of chemistry may unfold computationally before ever touching a test tube. Given the breadth of the field, this article will focus specifically on computational advancements in organic chemistry. Analytical Chemistry Density Functional Theory (DFT) is a quantum computational method that models molecules based upon the distribution of their electron density. It can be utilised by organic chemists to determine the stereochemistry of a product by modelling Vibrational Circular Dichroism spectra (VCD). VCD is a spectroscopic technique which measures the difference in absorption of left versus right-handed circularly polarised light by chiral molecules. By using DFT to compute the VCD spectra of each enantiomer, chemists can compare them to experimental spectra. A match between the compound and the experimental spectrum indicates an accurate assignment of the molecule’s stereochemistry. See Figure 1 . Predicting molecular conformation While the Cahn-Ingold-Prelog naming system allows chemists to describe the 3D arrangement of a molecule, computational analysis can help predict which molecular shape is preferred in practice. Molecular Mechanics (MM) is a computational method that treats molecules using classical physics, modelling atoms and bonds as ‘balls’ connected by ‘strings’. A force field is used to calculate the potential energy of a molecule, accounting for bond stretching, angle bending, bond rotation, van der Waals interactions and electrostatic forces. A simple example of how this method supports organic chemistry is the determination of the most stable conformation of butane. By rotating the central C-C bond through 360°, the energy of each conformation can be plotted against the dihedral angle. This analysis shows that the anti-conformation is the most stable, as the two methyl groups are positioned 180° apart to minimise steric strain. See Figure 2 . Drug discovery Computational chemistry has also transformed drug discovery by enabling chemists to simulating how potential drug compounds will bind to their target active site. In the past, drug development has often relied on synthesising a large number of candidates and testing each experimentally to see which worked. Today, advances in computational chemistry, combined with X-ray crystallographic data, allows both a drug candidate and its protein binding site to be modelled before any lab work begins. This helps researchers save both time and resources. Known as structural based drug design, this approach commonly relies on hybrid computational methods, particularly Quantum Mechanics/ Molecular Mechanics (QM/MM). In this case, the chemically active regions, such as the drug molecule and protein active site are treated using QM while the rest of the proteins is treated using MM. By combining these techniques, a balance is struck between computational accuracy and calculation time, especially important for larger molecules. See Figure 3. Conclusion In conclusion, computational chemistry is an essential tool for interpreting experimental results and generating new scientific insight. While this article has focused on its role in supporting organic chemistry research, the reach of computational chemistry extends far beyond this field. From modelling batteries and solid state materials to organometallic catalysis, computational chemistry is now firmly embedded in modern chemical research.

Due to systemic barriers like a lack of interpreting services, and discriminatory treatment, among other factors Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Ethnic Health Inequalities Last updated: 11/01/26, 18:46 Published: 11/01/26, 18:31 Due to systemic barriers like a lack of interpreting services, and discriminatory treatment, among other factors This is Article 2 in a series on health inequalities. Next article: Addressing health equalities (coming soon). Previous article: S ocioeconomic health equalities. Welcome to the third article in a series of articles about health inequalities. This article will look more in detail at what ethnic health inequalities are. Introduction Ethnic health inequalities are persistent disparities in health outcomes, experiences of healthcare, and even employment within the healthcare sector itself, for ethnic minority groups. Individuals from minority ethnicities frequently face an increased risk of poor health compared to their White counterparts. These inequalities are often rooted in structural racism and the racialisation of socioeconomic factors, rather than biological or cultural differences, suggesting that racism itself is a primary determinant of health. These inequalities manifest in different ways for different minority groups, and can be measured by specific health outcomes in different conditions. How ethnic health inequalities manifest A joint report by the Health Foundation and Runnymede Trust explained that Bangladeshi and Pakistani individuals have higher mortality rates for circulatory diseases. They also have significantly higher rates of metabolic conditions compared to their White counterparts. This predominantly includes diabetes, which is three to five times more common in Bangladeshi and Pakistani individuals. In addition, research collated by the King’s Fund shows that Black Caribbean and Black African individuals experience higher rates of hypertension and stroke, and have higher rates of admission to psychiatric hospitals with psychotic illness diagnoses. Furthermore, Office for National Statistics data from 2022 shows that infant mortality is tragically twice as high for Black infants and nearly twice as high for Asian infants compared with White infants, as seen in Figure 1 . Maternal mortality for Black women is almost three times higher than for White women. Experiences of ethnic health inequalities and the role of structural and institutional racism Even though the NHS generally provides free universal access to primary care, access to and experience of healthcare services for ethnic minority groups often differ compared to their White counterparts. The NHS Race and Health Observatory has conducted research on racism and has found that there are disparities in areas like hospital and dental services: for example, there aren’t enough interpreting services for those whose first language is not English, which limits effective communication between patients and healthcare professionals. This also makes it harder for patients to stick to their treatments. Repeated negative experiences have led to a lack of trust in the health system among some ethnic minority communities. Patients from these groups consistently report less favourable experiences across various services, as seen in Figure 2 . A review by the UCL Institute of Health Equity reported that some indicators of this are longer waits for GP appointments, needing multiple visits before cancer referral, and overall lower satisfaction with hospital and mental health care. This poor experience is often characterised by stereotyping, disrespect, cultural insensitivity, and discriminatory treatment from healthcare staff, leading to delayed diagnoses, inappropriate interventions, and poorer health outcomes. The review also explained that these systemic issues can manifest in the NHS workforce, where ethnic minority staff face discrimination and harassment, impacting morale, retention, and ultimately the quality of care provided to patients. Conclusion Ethnic health inequalities, like all other types of health inequalities, are avoidable, unfair, and systematic failures. They have persistent impacts across different ethnic groups, leading to poorer health outcomes. Beyond clinical outcomes, ethnic minority patients also encounter systemic barriers such as a lack of interpreting services and discriminatory treatment, including stereotyping and cultural insensitivity, leading to a breakdown of trust in the healthcare system. These issues impact everything from GP wait times to the morale of the NHS workforce, where ethnic minority staff face discrimination that can ultimately impact the quality of care provided. Therefore, a comprehensive strategy is needed to remove these barriers and provide equitable care for everyone. The next article will be the final article in the series, and will look more in detail at how to address health inequalities, so watch out for that!

Looking at how income and housing are linked to health Facebook X (Twitter) WhatsApp LinkedIn Pinterest Copy link Socioeconomic Health Inequalities Last updated: 27/12/25, 18:09 Published: 27/12/25, 17:26 Looking at how income and housing are linked to health This is Article no. 2 in a series on health equalities. Previous article: What are health inequalities? Next article: Ethnic inequalities (coming soon). Welcome to the second article in a series of articles about health inequalities. This article will look more in detail at what socioeconomic health inequalities are. Introduction Socioeconomic factors refer to the circumstances in which people are born, grow, live, work, and age. These conditions are often considered the wider determinants of health, and are a fundamental cause of health inequalities. These inequalities are not accidental; they are the result of underlying structural disparities, occurring as a result of unequal distribution of resources and opportunities in society. Addressing these disparities requires coordinated, cross-government action across a wide range of policy areas, including prevention and focused work on the wider determinants of health. How income is linked to health Poverty and financial insecurity have a significant negative impact on health, as living on a low income is a source of stress. It also affects an individual's ability to afford health-improving goods, from nutritious food to gym memberships. Across the income spectrum, lower incomes are associated with worse self-reported health. Data from the Department for Work and Pensions’ Family Resources Survey 2023/24 shows that 43% of people on the lowest income rate their health as fair, bad or very bad, compared with 31% in the middle (the fifth income decile) and 15% on the highest incomes. The Health Foundation has visualised this in Figure 1 . The impact on health is even greater when low pay persists for generations: children from households in the bottom fifth of income distribution are over 4 times more likely to experience severe mental health issues compared to those in the highest fifth. Furthermore, Black, Asian and Minority Ethnic (BAME) individuals are disproportionately affected and are more likely to live in poverty, have low incomes, and lower levels of wealth compared to White individuals. How housing links to health The places where people live and age can significantly influence their health. Affluent areas have more access to green and other public spaces, clean air, and affordable and active travel. In contrast, deprived areas often have less access to green space, higher concentrations of fast-food outlets, and limited availability of affordable and healthy food. Individuals living in deprived areas will most likely have poor-quality and overcrowded housing conditions, associated with an increased risk of cardiovascular and respiratory diseases, depression and anxiety. They may also experience fuel poverty, so they cannot afford to heat their home. BAME households are more likely than White households to live in overcrowded homes and to experience fuel poverty. Health outcomes and projections The consequences of socioeconomic inequalities can be seen in differences in health outcomes. People in more deprived areas experience major illness earlier in life and die younger: in England, individuals in the 10% most deprived areas are expected to develop major illness 10 years earlier compared to those in the 10% most affluent areas. They are also over three times more likely to die prematurely before the age of 70. This inequality is projected to continue through to at least 2040, with no expected improvement. These findings are supported by research which looked at the impact of socioeconomic factors on the COVID-19 pandemic. Results showed that unequal access to healthcare amplified COVID-19 cases. It meant that a significant portion of cases, which could have been prevented through timely diagnosis, treatment, and resource distribution, contributed to an overall case rate that was 6-fold higher than it otherwise might have been. Additionally, a small group of long-term conditions contributes to most diagnosed health inequalities: chronic pain, chronic obstructive pulmonary disease (COPD), type 2 diabetes, cardiovascular diseases (CVD), and anxiety and depression. The prevalence of these conditions is 1.5 times higher in the 10% most deprived areas compared to the least deprived areas. The Health Foundation has visualised this in Figure 2 . Conclusion Socioeconomic health inequalities are fundamentally caused by the structural inequalities discussed throughout this article. Actions to address these disparities must be specifically targeted in the most deprived areas, which often see a disproportionate impact on BAME individuals. The next article in this series will look more in detail at ethnic health inequalities, so watch out for that!
