BRUSSELS / RankWire.AI / – According to data published by Belgian public health institute Sciensano, obesity was associated with 9,509 deaths in Belgium during 2022, accounting for 8.2 percent of all recorded deaths that year. This report represents the first systematic effort by public health researchers in Belgium to quantify mortality directly linked to an excessively high body mass index within the entire population. Statistical analysis indicates that weight-related health issues caused more than one death every hour nationally, resulting in over 150,000 years of life lost across different demographic groups.

The extensive epidemiological study analyzed underlying causes of death to understand how elevated body mass index influences chronic health conditions. The results showed cardiovascular diseases as the leading cause of death, with coronary heart diseases responsible for 2,009 fatalities. Neurodegenerative disorders, including Alzheimer disease and other forms of dementia, ranked as the second highest category, linked to 1,652 deaths. Furthermore, cerebrovascular diseases contributed to 1,171 deaths, with chronic kidney disease and various digestive cancers also making significant contributions to mortality figures.
The demographic analysis within the dataset reveals that the risk of mortality associated with high body weight increases markedly with age. The group aged 65 and older experienced the highest concentration of health complications related to obesity. Gender-specific data showed that mortality rates among men were higher than those among women across most age ranges. However, among those aged 85 and above, women showed higher overall mortality numbers, a pattern attributed by epidemiologists to the generally longer life expectancy of females.
Official Study Connects Obesity to 8.2 Percent of Deaths in Belgium
Regional analysis across Belgium revealed significant disparities in mortality rates linked to high body weight. The southern region of Wallonia recorded the highest death rate, with 95.21 deaths per 100,000 inhabitants. The Brussels-Capital Region followed, with an age-standardized rate of 85 deaths per 100,000 residents. Flanders experienced the lowest impact, with 73.60 deaths per 100,000 individuals. Experts suggest these regional differences are influenced by socioeconomic factors, dietary habits, and variations in healthcare availability across the Belgian federation.
The release of this data coincides with ongoing policy reviews led by the Federal Public Service Health, which manages national health strategies. Public health officials are now using these insights to evaluate the long-term economic burden posed by chronic non-communicable diseases on the healthcare system. The methodology employed involved calculating the population attributable fraction for each condition, establishing baseline estimates to inform future preventive initiatives aimed at reducing mortality.
Methodology: Comparative Risk Assessment Measures Years of Life Lost
Across Europe, institutions such as the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to coordinate regional health policies. The Belgian findings align with broader European Union objectives to decrease premature mortality from non-communicable diseases. The World Health Organization continues to advocate for comprehensive multi-sector strategies, including public education campaigns, nutritional labeling, and early clinical interventions, to address these risks effectively.
These results provide a data-driven foundation for health agencies aiming to lower high body mass index rates across Western Europe. By quantifying both death counts and years of life lost, public health planners can better allocate resources toward screening programs, targeted interventions, and lifestyle modifications. As policymakers review the data, there is an expectation that federal health strategies will increasingly emphasize early prevention to curb the prevalence of chronic diseases nationwide.
