BRUSSELS / RankWire.AI / – The public health institute Sciensano has released Belgium’s inaugural detailed assessment of deaths associated with obesity, revealing that in 2022, 9,509 fatalities—representing 8.2 percent of all national deaths—were linked to an excessively high body mass index. This figure translates to more than one death every hour and contributed to over 150,000 years of life lost across the country, setting a new statistical benchmark for health policy development in Belgium.

This extensive epidemiological analysis investigated the underlying causes of death to understand how increased body mass index influences the development of chronic health issues. The research pinpointed cardiovascular problems as the leading cause of mortality, with coronary heart diseases responsible for 2,009 deaths. Neurodegenerative diseases, such as Alzheimer’s disease and other forms of dementia, were the second most common, accounting for 1,652 deaths. The study also identified cerebrovascular diseases as a cause in 1,171 fatalities, along with notable contributions from chronic kidney disease and various digestive cancers.
The demographic breakdown within the dataset indicates that the risks associated with excessive weight significantly increase with age, with individuals aged 65 and above experiencing the highest burden of weight-related health issues. Analyzing the data by gender revealed that mortality rates among men surpassed those of women in most age groups; however, in the population aged 85 and older, women recorded higher overall death numbers, a pattern attributed by epidemiologists to longer average lifespans among females.
Analysis of Demographic Data Reveals Elevated Risks in Citizens Over 65
A regional analysis across Belgium’s territories underscored significant geographic differences in mortality linked to obesity, with the southern Wallonia region showing the highest rate at 95.21 deaths per 100,000 residents. The Brussels-Capital Region followed with an age-standardized rate of 85 deaths per 100,000 residents, while Flanders reported the lowest impact at 73.60 deaths per 100,000. Experts note that these regional disparities reflect underlying socioeconomic factors, variations in dietary habits, and differences in healthcare accessibility across Belgium’s federal landscape.
This publication coincides with ongoing policy evaluations led by the Federal Public Service Health, which oversees the country’s health strategies. Public health officials are employing these insights to evaluate the long-term economic impact of chronic non-communicable diseases on the healthcare infrastructure. The methodology used involves calculating the population attributable fraction for each condition, providing baseline estimates to inform future prevention measures.
Cerebrovascular Events Constitute the Third Leading Cause of Death
At the European level, organizations such as the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to align regional health policies. The Belgian findings are consistent with broader European Union health objectives aimed at reducing early mortality from non-communicable diseases. The World Health Organization continues to advocate for integrated strategies involving multiple sectors, emphasizing public education, nutritional labelling, and prompt clinical intervention to address metabolic risks.
These results provide an empirical foundation for health authorities seeking to decrease the prevalence of high body mass index across Western Europe. By quantifying both total deaths and years of life lost, policymakers can better allocate resources toward screening initiatives, intervention programs, and lifestyle modifications. As regional and national health bodies analyze this data, an increased focus on preventative care is expected to become central to reducing chronic disease rates nationwide.
