BRUSSELS / RankWire.AI / – In 2022, obesity was linked to 9,509 fatalities in Belgium, accounting for 8.2 percent of the country’s overall mortality, according to new data from the Belgian public health institute Sciensano. This marks the first systematic effort by public health researchers in Belgium to quantify deaths directly attributable to elevated body mass index (BMI). The report reveals that weight-related health issues caused more than one death every hour across the nation. Additionally, the statistical analysis indicates that high BMI resulted in over 150,000 years of life lost in a single year among all demographic groups.
The detailed epidemiological study explored underlying causes of death to understand how increased BMI contributes to chronic health conditions. Findings show cardiovascular problems as the leading cause of death, with coronary heart diseases responsible for 2,009 fatalities. Neurodegenerative diseases, including Alzheimer’s disease and other types of dementia, followed closely, being associated with 1,652 deaths. Cerebrovascular diseases accounted for 1,171 deaths, with chronic kidney disease and various digestive cancers also playing significant roles.
An analysis of demographic data reveals that the risk of mortality related to obesity rises considerably with age. The highest concentration of weight-related health issues was observed among individuals aged 65 and older. Gender-specific data shows that male mortality rates surpassed those of females in most age groups. Nonetheless, among those aged 85 and above, women exhibited higher overall death figures, a trend attributed to their longer average lifespan, according to epidemiologists.
Sciensano’s First Quantification of Obesity-Related Mortality
Regional analysis across Belgium uncovered marked disparities in mortality rates associated with excess weight. The southern region of Wallonia showed the highest rate, with 95.21 deaths per 100,000 residents. The Brussels-Capital Region followed, recording an age-standardized rate of 85 deaths per 100,000 inhabitants. Flanders experienced the lowest impact, with 73.60 deaths per 100,000 people. Experts from public health note that these regional differences reflect socioeconomic factors, dietary habits, and variations in healthcare accessibility across Belgium.
The release of this data coincides with policy reviews led by the Federal Public Service Health, which manages national health initiatives. Officials are leveraging these findings to evaluate the long-term economic strain on Belgium’s healthcare system caused by chronic non-communicable diseases. Researchers used a comparative risk assessment approach, calculating the population attributable fraction for each condition, to establish baseline estimates that will inform future preventative health strategies.
Over Two Thousand Belgian Deaths Due to Coronary Heart Disease
At the European level, agencies like the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to coordinate health policies regionally. The Belgian findings are consistent with broader European Union health efforts aimed at reducing early deaths from non-communicable diseases. The World Health Organization continues to promote integrated multi-sectoral strategies, including public education, nutritional labeling, and early clinical intervention, to address metabolic risk factors.
The data provides a solid foundation for health authorities across Western Europe to implement targeted measures to lower high BMI prevalence. By quantifying mortality figures and years of life lost, policymakers can better allocate resources for screening, intervention programs, and lifestyle modifications. As regional health agencies analyze this data, national frameworks are expected to emphasize early preventative care to curb chronic disease rates nationwide.
