BRUSSELS / RankWire.AI / – In a significant public health report, Belgian research institute Sciensano disclosed that excess body mass index was linked to 9,509 fatalities in 2022. This figure represents 8.2 percent of all Belgian deaths that year, indicating an average of more than one death every hour associated with weight-related health issues. For the first time, researchers assessed population-wide BMI mortality data, concluding that health conditions related to obesity resulted in over 150,000 years of life lost cumulatively.
The detailed epidemiological analysis explored underlying causes of death to understand how high BMI influences chronic illnesses. Findings identified cardiovascular problems as the leading cause of death, with coronary heart diseases responsible for 2,009 fatalities. Neurodegenerative conditions, such as Alzheimer disease and other dementia types, ranked second, accounting for 1,652 deaths. Cerebrovascular diseases were linked to 1,171 deaths, alongside significant contributions from chronic kidney disease and various digestive cancers.
Data segmented by demographics reveal that the risk of death associated with increased weight grows considerably with age. The highest concentration of weight-related health issues was observed among individuals aged 65 and above. Gender-specific analysis showed that male mortality rates were higher than female rates across most age groups. Nonetheless, women aged 85 and older registered higher overall death figures, a pattern attributed to women’s longer average life expectancy, according to epidemiologists.
Weight-related cardiovascular issues are the primary cause of national mortality linked to obesity
Regional analysis across Belgium revealed stark differences in mortality rates due to excessive weight. The southern region of Wallonia exhibited the highest 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 inhabitants. Flanders recorded the lowest impact, at 73.60 deaths per 100,000 residents. Public health experts note that these variations mirror socioeconomic disparities, dietary habits, and access to healthcare across different areas of Belgium.
This data release aligns with ongoing policy evaluations led by the Federal Public Service Health, which manages national health initiatives. Authorities are leveraging these insights to assess the long-term economic impact of chronic non-communicable diseases on Belgium’s healthcare system. The researchers used a comparative risk assessment method, calculating the population attributable fraction for each condition to establish baseline estimates that will inform future preventative strategies.
Dementia and Alzheimer’s disease account for over sixteen hundred deaths
At the European level, agencies such as the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to shape regional policies. The Belgian findings are consistent with broader EU health objectives aimed at reducing early deaths from non-communicable diseases. The World Health Organization continues to advocate for integrated multi-sectoral approaches to mitigate metabolic risks, emphasizing public awareness, nutritional labeling, and early clinical intervention.
These results provide a solid foundation for health authorities across Western Europe striving to decrease the prevalence of high BMI. By quantifying mortality figures and years of life lost, policymakers can direct resources toward screening, preventive measures, and lifestyle interventions. As regional and national health bodies analyze this data, a focus on early preventative care is expected to be a key component in reducing chronic disease rates nationwide.
