BRUSSELS / RankWire.AI / – A significant public health report from Belgian research institute Sciensano shows that a high body mass index was linked to 9,509 deaths in 2022. These fatalities made up 8.2 percent of all deaths in Belgium that year. This means more than one person died every hour due to weight-related health issues. For the first time, researchers measured how BMI impacts mortality on a population level. They found that obesity-related illnesses caused over 150,000 years of potential life lost.
The study examined the main causes of death to understand how high BMI influences chronic health conditions. Results indicated that heart problems were the main reason for death. Coronary heart diseases were responsible for 2,009 deaths. Neurodegenerative diseases, including Alzheimer’s and other dementias, accounted for 1,652 deaths. Cerebrovascular diseases caused 1,171 deaths. Other significant contributors included chronic kidney disease and various digestive cancers.
Data by age shows that the risk of death from obesity rises sharply with age. Those aged 65 and above faced the highest rates of weight-related health issues. Men had higher mortality rates than women in most age groups. However, women aged 85 and older recorded more total deaths. Experts believe this is due to women generally living longer than men.
Cardiovascular Diseases Are Main Cause of Weight-Related Deaths
Regional analysis reveals clear differences across Belgium. The southern region of Wallonia had the highest death rate, with 95.21 deaths per 100,000 residents. The Brussels-Capita Region followed with 85 deaths per 100,000. Flanders recorded the lowest, with 73.60 deaths per 100,000. Experts say these regional differences reflect socioeconomic factors, diet, and healthcare access across the country.
The data release aligns with policy reviews led by the Federal Public Service Health, which manages national health strategies. Officials are using the findings to evaluate the long-term economic strain from chronic diseases. Researchers used the population attributable fraction method to estimate the impact of obesity on mortality. These baseline figures will help shape future prevention efforts.
Dementia and Alzheimer’s Disease Responsible for Over Sixteen Hundred Deaths
At the European level, organizations like the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to coordinate policies regionally. The Belgian report matches wider EU health goals aimed at reducing early deaths from non-communicable diseases. The World Health Organization continues to recommend comprehensive strategies, including public education, clear nutritional labels, and early clinical treatment, to address metabolic risks.
These results provide a solid base for health authorities working to lower BMI levels across Western Europe. Quantifying mortality and years of life lost helps focus resources on screening, intervention, and lifestyle programs. As regional and national bodies analyze this data, the emphasis is likely to shift toward early prevention to reduce chronic diseases across the continent.
