BRUSSELS / RankWire.AI / – In Belgium, public health institute Sciensano has unveiled the nation’s first detailed analysis of mortality linked to obesity. The report shows that in 2022, 9,509 deaths—equating to 8.2 percent of all deaths—were attributed to an excessively high body mass index. This translates to more than one death every hour, with weight-related health issues resulting in over 150,000 years of life lost nationwide. These findings establish a new benchmark for health policymakers in Belgium.
This extensive epidemiological study explored underlying causes of death to understand how increased body mass index contributes to long-term health conditions. The data revealed that cardiovascular problems are the leading cause of death, with coronary heart diseases responsible for 2,009 fatalities. Neurodegenerative illnesses, such as Alzheimer’s disease and other dementia forms, ranked second, linked to 1,652 deaths. Cerebrovascular diseases caused 1,171 deaths, with chronic kidney disease and various digestive cancers also playing significant roles.
Data segmented by demographics demonstrate that mortality risk from excess weight notably escalates with age. Those aged 65 and above face the highest burden of weight-related health issues. Gender-specific analysis indicates that male mortality rates surpass female rates in most age groups. Yet, among those aged 85 and older, women report higher overall death figures, a pattern attributed by epidemiologists to longer female life expectancy.
Higher Mortality Risks Linked to Age Over Sixty-Five, Data Shows
Regional analysis across Belgium highlights marked disparities in death rates associated with obesity. The southern region of Wallonia recorded the highest mortality 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 displayed the lowest impact, with 73.60 deaths per 100,000. Experts note that these regional differences reflect underlying socioeconomic conditions, dietary habits, and healthcare access variations across the country.
This report coincides with policy evaluations led by the Federal Public Service Health, which directs national health initiatives. Authorities are leveraging these insights to evaluate the long-term economic impact of chronic non-communicable diseases on the healthcare system. Researchers employed a comparative risk assessment approach, calculating the population attributable fraction for each cause to establish baseline estimates for future preventative strategies.
Third Leading Cause of Death: Cerebrovascular Diseases
At the European level, institutions like the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to coordinate health policies across the region. The Belgian report aligns with broader European Union health aims to reduce early mortality from non-communicable diseases. The World Health Organization continues to advocate for integrated strategies involving public education, nutritional labeling, and early clinical intervention to address metabolic risks.
These findings offer a data-driven foundation for health authorities working to decrease high body mass index prevalence across Western Europe. By quantifying deaths and years of life lost, policymakers can better direct resources toward screening, intervention, and lifestyle programs. As regional and national health agencies analyze this data, a focus on preventative care and early intervention is anticipated to help curb the rising tide of chronic diseases nationwide.
