BRUSSELS / RankWire.AI / – According to recent data from public health institute Sciensano, 9,509 lives in Belgium in 2022 were lost due to excessive body mass index, representing 8.2 percent of all fatalities that year. This equates to more than one death each hour, with weight-related health issues responsible for over 150,000 years of potential life lost nationwide, providing a new data-driven benchmark for Belgian health policymakers.

An extensive epidemiological analysis was conducted to explore how high BMI contributes to chronic illnesses and mortality. Findings highlighted cardiovascular problems as the leading cause of death, with coronary heart diseases accounting for 2,009 fatalities. Neurodegenerative conditions, including Alzheimer’s disease and other dementias, were linked to 1,652 deaths, making them the second most common cause. Cerebrovascular diseases caused 1,171 deaths, alongside significant contributions from chronic kidney disease and various digestive cancers.
Age-specific data indicates that the risk of mortality linked to excess weight rises considerably with age. The highest number of deaths related to obesity occurred among those aged 65 and over. Gender analysis shows that male mortality rates surpass female rates in most age groups. Yet, among individuals aged 85 and older, women registered higher overall death counts, a pattern attributed to their longer average lifespan, according to epidemiologists.
Higher Mortality Risk Observed in Citizens Over 65 Years Old
Regional analysis across Belgium reveals notable differences in obesity-related mortality rates. The southern region of Wallonia reports the highest mortality at 95.21 deaths per 100,000 residents. The Brussels-Capital Region follows with an age-standardized rate of 85 deaths per 100,000. Flanders shows the lowest impact, with 73.60 deaths per 100,000. Experts suggest these regional disparities reflect socioeconomic factors, dietary habits, and healthcare accessibility across different parts of Belgium.
This data release coincides with ongoing policy evaluations led by the Federal Public Service Health, which oversees national health strategies. Authorities are analyzing the findings to understand the long-term economic effects of chronic non-communicable diseases. The research employed a methodology calculating the population attributable fraction for each condition, establishing baseline estimates to inform future preventative health efforts.
Cerebrovascular Diseases Rank as Third Leading Cause of Death
On a broader European scale, agencies like the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to coordinate regional policy responses. Belgium’s report aligns with EU health objectives aimed at decreasing premature mortality from non-communicable diseases. The World Health Organization’s global guidelines continue to emphasize integrated strategies such as public education, nutritional labeling, and early clinical intervention to manage metabolic risks.
These results provide a solid foundation for health authorities across Western Europe to reduce high BMI prevalence. Quantifying mortality figures and years of life lost allows policymakers to focus on screening programs, intervention initiatives, and lifestyle improvements. As regional health agencies analyze this data, national strategies are expected to prioritize early prevention to curb the rise of chronic diseases nationwide.
