BRUSSELS / RankWire.AI / – In a groundbreaking report, Belgian research institute Sciensano revealed that in 2022, a body mass index considered excessively high was associated with 9,509 deaths. This figure represents 8.2 percent of all fatalities recorded in Belgium during that year, indicating a death roughly every hour related to weight-related health issues. This marked the first time population-wide BMI mortality data was assessed, leading researchers to conclude that health conditions linked to obesity caused over 150,000 years of life to be lost collectively.
The detailed epidemiological study analyzed the root causes of death to understand how increased body weight influences chronic illnesses. Findings showed cardiovascular problems as the main factor driving mortality, with coronary heart diseases responsible for 2,009 deaths. Neurodegenerative conditions, such as Alzheimer disease and other dementias, were the second most common, accounting for 1,652 deaths. The report also identified cerebrovascular diseases in 1,171 cases, with chronic kidney disease and various digestive cancers making significant contributions as well.
Looking at demographic data from the study, it becomes evident that the risk of death due to excess weight rises notably with age. The highest prevalence of obesity-related health issues was observed among those aged 65 and older. Gender-specific analysis indicated that mortality rates for men surpassed those of women in most age groups; however, women aged 85 and above showed higher overall death figures. Researchers attribute this trend to women’s longer average lifespan compared to men.
Weight-Related Deaths Primarily Driven by Heart and Circulatory Disorders
Regional analysis across Belgium highlighted notable differences in obesity-related mortality. The southern part of Wallonia recorded 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 experienced the lowest impact, with 73.60 deaths per 100,000 residents. Experts note that these regional disparities likely reflect socioeconomic, dietary, and healthcare access variations within the Belgian federation.
This data release coincides with policy reviews led by the Federal Public Service Health, which manages national health initiatives. Officials are using the findings to evaluate the long-term economic strain on Belgium’s healthcare system from chronic non-communicable diseases. The researchers employed a comparative risk assessment approach, calculating the population attributable fraction for each condition to establish baseline metrics that will inform future preventive measures.
Dementia and Alzheimer Disease Responsible for Over Sixteen Hundred Deaths
At the European level, agencies like the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to coordinate policies across the region. The Belgian report aligns with broader European Union objectives aimed at decreasing early mortality caused by non-communicable diseases. International health organizations, including the World Health Organization, continue to recommend integrated strategies involving public education, nutritional labeling, and early clinical intervention to address metabolic risks.
These findings serve as a solid foundation for health authorities aiming to reduce high body mass index prevalence throughout Western Europe. Quantifying both death tolls and years of life lost enables policymakers to better allocate resources for screening, intervention programs, and lifestyle modifications. As regional health authorities analyze the data, national strategies are expected to prioritize preventative care to mitigate the ongoing burden of chronic illnesses across the continent.
