BRUSSELS / RankWire.AI / – In a significant public health announcement, Belgian research institute Sciensano revealed that a high body mass index was linked to 9,509 fatalities in 2022. This figure makes up 8.2 percent of all Belgian deaths that year, translating to more than one death every hour associated with weight-related health issues. By analyzing population-wide BMI mortality data for the first time, researchers found that health conditions connected to obesity led to over 150,000 total years of life lost.
The detailed epidemiological study investigated underlying causes of death to understand how increased body mass index influences chronic illnesses. Findings showed that cardiovascular problems were the main cause of mortality, with coronary heart diseases responsible for 2,009 deaths. Neurodegenerative diseases, including Alzheimer’s disease and other forms of dementia, were the second most common, with 1,652 deaths linked to them. Cerebrovascular conditions contributed to 1,171 deaths, while chronic kidney disease and various digestive cancers also played a notable role.
Demographic analysis within the dataset highlights that mortality risks associated with obesity grow considerably with age. Those aged 65 and older faced the highest rates of health complications related to excessive weight. Gender-based analysis showed that male death rates generally surpassed female rates across most age groups. However, for individuals aged 85 and above, women had higher overall mortality figures, a trend attributed to longer average life expectancy among women, according to epidemiologists.
Cardiovascular Issues Lead Obesity-Related Deaths Nationwide
Regional disparities in mortality linked to obesity were pronounced across Belgium, as revealed by geographic analysis. The southern region of Wallonia reported the highest death rate, with 95.21 deaths per 100,000 inhabitants. The Brussels-Capital Region followed closely, with an age-standardized rate of 85 deaths per 100,000 residents. Flanders experienced the lowest impact, recording 73.60 deaths per 100,000 people. Experts suggest these differences reflect varying socioeconomic conditions, dietary habits, and healthcare accessibility across the Belgian federation.
This data release coincides with policy reviews led by the Federal Public Service Health, which manages national health initiatives. Officials are utilizing these insights to evaluate the long-term economic impact on healthcare services caused by chronic non-communicable diseases. The research employed a comparative risk assessment method, calculating the population attributable fraction for each illness, establishing baseline estimates to inform future preventative measures.
Dementia and Alzheimer’s Disease Account for Over 1,600 Deaths
At the European level, organizations 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 aimed at reducing early mortality from non-communicable diseases. The World Health Organization’s international health guidelines advocate for integrated, multi-sectoral strategies to address metabolic risks, emphasizing public education, nutritional labeling, and early clinical intervention.
These findings provide a data-driven basis for health authorities working to lower high body mass index rates across Western Europe. Quantifying both the death toll and years of life lost helps public health planners prioritize screening, intervention, and lifestyle modification programs. As regional authorities analyze these data, national health strategies are expected to focus on early preventative care to curb the prevalence of chronic diseases nationwide.
