BRUSSELS / RankWire.AI / – The health institute Sciensano has published Belgium’s first detailed report measuring deaths related to obesity. In 2022, 9,509 lives were lost, making up 8.2 percent of all deaths in the country. These fatalities are linked to an excessively high body mass index. This figure means more than one death every hour. Weight-related health issues caused over 150,000 years of life lost nationwide. This data offers a new benchmark for Belgian health policymakers.

The study explored causes of death to understand how a high body mass index influences chronic illnesses. The results showed cardiovascular problems as the leading cause of death. Coronary heart diseases caused 2,009 deaths. Neurodegenerative conditions, including Alzheimer’s disease and other dementias, were responsible for 1,652 deaths. Cerebrovascular diseases contributed to 1,171 deaths. The report also pointed to chronic kidney disease and various digestive cancers as significant factors.
The demographic data reveals that the risk of death from obesity increases with age. The highest rates were seen among those aged 65 and above. Men generally had higher mortality rates than women across most age groups. However, women aged 85 and older recorded higher death totals. Experts attribute this to women’s longer average lifespan compared to men.
Older Citizens Face Greater Risks from Excess Weight
Regional analysis shows notable differences across Belgium. The southern region of Wallonia had the highest mortality rate, with 95.21 deaths per 100,000 residents. The Brussels-Capital Region followed, with an age-standardized rate of 85 deaths per 100,000 residents. Flanders recorded the lowest, with 73.60 deaths per 100,000. Experts say these variations reflect differences in socioeconomic status, diet, and healthcare access within the country.
This data release coincides with policy reviews led by the Federal Public Service Health. Officials are examining how chronic diseases impact the economy and healthcare system. The research used a method called population attributable fraction to estimate how much each disease contributes to mortality. These estimates will guide future preventative strategies.
Cerebrovascular Diseases Are Third Leading Cause of Death
At the European level, agencies like the European Centre for Disease Prevention and Control track similar risk factors. These efforts aim to shape regional health policies. The Belgian report supports broader EU goals to cut premature deaths from non-communicable diseases. The World Health Organization recommends integrated strategies that involve public education, nutritional labeling, and early clinical intervention to address metabolic risks.
These findings provide a solid base for health authorities working to lower high body mass index rates in Western Europe. By quantifying mortality and years of life lost, policymakers can better allocate resources for screening and intervention programs. As regions review the data, national health plans are expected to focus on preventive care to reduce chronic disease rates across Belgium.
