Global Diabetes Cases Top 800 Million Amid Soaring Rates in Low-Income Nations, Study Finds

Published

on

The number of people living with diabetes has surpassed 800 million worldwide, a figure that has more than doubled over the past three decades, according to a new study published in The Lancet. Conducted by the NCD Risk Factor Collaboration and the World Health Organization (WHO), the analysis highlights alarming disparities in diabetes prevalence and treatment across regions.

Drawing on data from over 140 million adults across 200 countries and territories, the study revealed that global diabetes rates rose from 7% in 1990—approximately 198 million cases—to 14% in 2022, amounting to 828 million people.

Rising Prevalence and Treatment Challenges

The findings underscore a troubling trend: more than half of all individuals with diabetes, particularly in low- and middle-income countries, lack access to treatment. This is especially concerning as diabetes remains a leading cause of severe health complications, including blindness, kidney failure, and heart disease, and was responsible for more than 2 million deaths in 2021.

“There’s a growing gap in diabetes treatment between high- and low-income countries,” said Majid Ezzati, senior author of the study from Imperial College London. “This inequality is especially alarming for younger individuals, who face a lifetime of health risks without proper intervention.”

The study attributed the rise in Type 2 diabetes—responsible for the majority of cases—to factors such as obesity and poor dietary habits. Unlike Type 1 diabetes, which is an autoimmune disease, Type 2 diabetes can often be prevented through healthier lifestyles, including balanced diets, regular physical activity, and avoiding tobacco use.

Global Disparities in Diabetes Rates

Diabetes prevalence varies significantly across the globe. Over half of all cases were concentrated in four countries: India (212 million), China (148 million), the United States (42 million), and Pakistan (36 million). Other nations with high numbers of cases include Indonesia (25 million) and Brazil (22 million).

The highest diabetes rates were reported in Pacific island nations, the Caribbean, and countries in the Middle East, North Africa, and Southeast Asia. Conversely, several high-income countries in Europe, such as France, Denmark, and Spain, recorded some of the lowest diabetes rates, with prevalence ranging from 2% to 4%.

Treatment Gaps and Regional Variations

The report highlighted stark differences in diabetes care. Belgium led in treatment coverage, with 86% of women and 77% of men receiving care. Other countries with strong treatment rates included Poland, Finland, and Portugal. However, less than half of those with diabetes in France, Latvia, and Lithuania were receiving treatment.

WHO Director-General Dr. Tedros Adhanom Ghebreyesus emphasized the urgent need for global action. “To control the diabetes epidemic, countries must implement policies promoting healthy diets, physical activity, and robust health systems for prevention and early treatment,” he stated.

The study’s findings serve as a stark reminder of the escalating global health crisis and the need for coordinated international efforts to address the growing burden of diabetes.

German Consumer Group Warns Against Children’s Dietary Supplements

Published

By

A leading German consumer group has raised concerns about the safety and necessity of dietary supplements for children, after testing 18 common products and finding issues in 17 of them. The findings highlight the potential risks of excessive vitamin intake and misleading advertising by supplement manufacturers.

High Dosages and Questionable Claims

Berlin-based consumer organization Stiftung Warentest conducted an analysis of 18 widely available children’s dietary supplements. The group examined their ingredients, compared them with recommended nutrient intake levels, and evaluated the accuracy of their advertised benefits. The results were alarming—15 of the products contained dosages exceeding recommended levels for children, while five had vitamin A levels higher than the maximum safe limit for adults.

The group concluded that these supplements are “unnecessary at best and risky at worst.” Their findings align with the stance of the German Federal Institute for Risk Assessment (BfR), which states that food supplements are generally not needed for healthy individuals with balanced diets and cannot compensate for poor nutrition.

Growing Popularity Despite Risks

Dietary supplements, regulated as food products in the European Union, have gained widespread popularity in recent years. A 2022 survey across 14 EU countries found that 93% of adults had used supplements in the past year, primarily for perceived health benefits.

For children, supplements are often marketed as tools to enhance growth, cognitive function, or immune strength. However, Stiftung Warentest’s analysis suggests that some of these claims may be misleading.

“Manufacturers use enticing messages and suggestive images to make their products appealing to parents—sometimes using advertising claims that are illegal,” the group reported.

When Supplements Might Be Necessary

While Stiftung Warentest’s findings highlight significant concerns, some experts caution against completely dismissing dietary supplements. Dr. Berthold Koletzko, president of the European Academy of Paediatrics (EAP) and a paediatric gastroenterologist at Ludwig Maximilian University of Munich, acknowledges that most children do not require supplements but notes exceptions.

“There are young children and adolescents with suboptimal supplies of critical nutrients and even deficiencies,” Koletzko said, pointing to vitamin D, calcium, and omega-3 fatty acids as examples.

Certain dietary restrictions, such as vegetarian or gluten-free diets, may increase the need for supplementation. A 2017 study found that 3.4% of German children aged 6 to 17 were vegetarians, a number Koletzko believes has since increased. Additionally, children living in areas with limited sunlight may require vitamin D supplementation.

However, Koletzko warns that not all supplements are equal. Gummy vitamins, for instance, are often high in sugar and may encourage overconsumption due to their candy-like appearance. Excessive vitamin and mineral intake can lead to digestive issues, including stomach discomfort and loose stools.

Expert Advice is Essential

For parents concerned about their child’s nutrition, Koletzko emphasizes the importance of consulting a trusted healthcare professional.

“If you choose a supplement, it’s crucial to select the right one and get advice from your paediatrician,” he advised.

As the debate over dietary supplements continues, Stiftung Warentest’s findings serve as a reminder that parents should approach them with caution, prioritizing a balanced diet over unnecessary supplementation.

US Tariffs on Pharmaceuticals Could Spark Global Trade Disruptions

Published

By

The pharmaceutical industry is bracing for potential upheaval as the United States considers imposing tariffs on drug imports, a move that could send shockwaves across global markets. President Donald Trump has signaled his intent to impose a 25% tariff on pharmaceuticals as part of a broader strategy to bring drug manufacturing back to the US.

Speaking from the Oval Office on Wednesday night, Trump confirmed his administration’s plans to target the pharmaceutical sector.

“We’re going to be doing tariffs on pharmaceuticals to bring our pharmaceuticals back,” he stated.

While the move aims to bolster domestic production, experts warn that the tariffs could lead to unintended consequences, including higher drug prices and supply chain disruptions that would impact both American and European companies. The US, a major importer of pharmaceuticals, heavily depends on European manufacturers for specialized medications. In 2023 alone, the US imported $170 billion (€157 billion) worth of pharmaceutical products, with $127 billion (€117 billion) coming from the EU.

European Markets at Risk

European pharmaceutical firms are particularly vulnerable to the proposed tariffs. Ireland, a key hub for American pharmaceutical companies, could face severe economic repercussions. In 2023, Ireland exported over €80 billion worth of pharmaceuticals to the US, accounting for more than half of its total exports. Major US firms like Pfizer, Johnson & Johnson, and Eli Lilly have significant operations in Ireland, and potential tariffs could lead to job losses and reduced investment.

Denmark’s pharmaceutical sector, especially Novo Nordisk, is also at risk. The company, a leader in diabetes and obesity treatments, generates over 50% of its revenue from the US market. Increased costs due to tariffs could impact American patients while also denting Denmark’s economic growth. The success of Novo Nordisk’s weight-loss drugs like Ozempic and Wegovy has been a major driver of Denmark’s GDP, contributing nearly half of its economic growth in 2023.

Impact on Other European Nations

Beyond Ireland and Denmark, other European pharmaceutical hubs would also feel the strain. Belgium, home to Pfizer’s major European production facilities, exported over $73 billion in pharmaceuticals in 2024, with a quarter of those exports going to the US. Germany’s pharmaceutical and biotech industries, including major players like Bayer and BioNTech, could also face setbacks. France, Italy, and Switzerland—key exporters of vaccines, generics, and high-value specialty drugs—would experience supply chain disruptions and financial strain.

EU Retaliation on the Horizon?

If the US proceeds with tariffs, the European Union may impose retaliatory measures targeting American pharmaceutical companies. The European Commission is reportedly exploring countermeasures, including higher export costs for US firms such as Pfizer, Merck, and Johnson & Johnson.

Additionally, the EU could prioritize domestic pharmaceutical companies in government contracts and revive stalled regulatory reforms, such as the General Pharmaceutical Legislation (GPL) reform, which aims to strengthen Europe’s pharmaceutical sovereignty. The recently proposed Critical Medicines Act could also serve as a framework to counterbalance US trade policies.

With negotiations ongoing, the global pharmaceutical industry is closely watching developments, as any trade war in this sector would have far-reaching consequences for businesses, patients, and healthcare systems on both sides of the Atlantic.

Scientists Discover Drug That Makes Human Blood Lethal to Mosquitoes

Published

By

Researchers have identified a promising new method to combat mosquito-borne diseases such as malaria by making human blood toxic to mosquitoes. Their study, published in Science Translational Medicine, suggests that a drug commonly used for rare diseases could help eliminate mosquitoes when ingested through a blood meal.

Nitisinone: A Potential Weapon Against Malaria

The study focused on nitisinone, a medication prescribed for individuals with rare inherited metabolic disorders that affect amino acid breakdown. The drug functions by blocking a specific enzyme, preventing harmful byproducts from accumulating in the human body.

When mosquitoes feed on blood containing nitisinone, the drug disrupts their digestion, ultimately leading to their death. This discovery could pave the way for a novel mosquito control strategy.

“One way to stop the spread of diseases transmitted by insects is to make the blood of animals and humans toxic to these blood-feeding insects,” said Lee R. Haines, associate research professor at the University of Notre Dame and co-lead author of the study.

The findings suggest that nitisinone could serve as an effective and complementary tool in the fight against malaria, which remains a major global health concern.

A Growing Need for Mosquito Control Solutions

Currently, personal protective measures such as bed nets, insect repellents, and window screens help reduce mosquito bites. Another approach involves the use of ivermectin, a drug that kills parasites and is sometimes used to target mosquitoes. However, repeated use of ivermectin can lead to drug resistance and environmental concerns.

Nitisinone, on the other hand, demonstrated significant advantages over ivermectin.

“Nitisinone performance was fantastic,” said Álvaro Acosta Serrano, professor of biological sciences at Notre Dame and co-corresponding author of the study. “It has a much longer half-life in human blood than ivermectin, meaning its mosquito-killing activity lasts much longer. This is critical when applied in the field for safety and economic reasons.”

Crucially, the drug proved effective in eliminating mosquitoes across all age groups, including older mosquitoes, which are the most likely to transmit malaria. It also showed effectiveness against insecticide-resistant mosquitoes.

A New Approach to Mosquito-Borne Disease Prevention

Haines suggested that in the future, alternating between nitisinone and ivermectin could enhance mosquito control efforts.

“For example, nitisinone could be used in areas where ivermectin resistance persists or where the drug is already heavily used for livestock and humans,” he said.

Mosquito-borne diseases, including malaria, dengue, West Nile virus, chikungunya, and yellow fever, continue to pose a growing health threat. The European Centre for Disease Prevention and Control (ECDC) has warned that climate change is creating more favorable conditions for invasive mosquito species in Europe, even though malaria was eradicated from the continent decades ago.

This new discovery offers a promising avenue for combating the spread of these diseases, potentially reducing the global burden of mosquito-borne infections.
