BRUSSELS / RankWire.AI / – In 2022, obesity was associated with 9,509 deaths in Belgium, accounting for 8.2 percent of the nation’s overall mortality, according to recent data from the Belgian public health institute Sciensano. This marks the first systematic attempt by Belgian public health researchers to quantify deaths directly linked to high body mass index (BMI). The report highlights that weight-related health issues caused more than one death every hour across the country. Moreover, the analysis shows that elevated BMI contributed to over 150,000 years of life lost among all demographic groups in a single year.
The detailed epidemiological study examined underlying causes of death to understand how high BMI influences chronic health problems. Cardiovascular issues emerged as the leading cause, with coronary heart diseases responsible for 2,009 deaths. Neurodegenerative conditions, particularly Alzheimer’s disease and other dementias, accounted for 1,652 deaths. Cerebrovascular diseases contributed to 1,171 fatalities, along with significant numbers from chronic kidney disease and various digestive cancers.
Data broken down by demographics indicates that mortality risks related to excess weight grow substantially with age. The highest burden was observed among those aged 65 and above. Gender analysis shows men generally had higher mortality rates than women across most age groups, but among those aged 85 and older, women recorded higher total death figures. Experts attribute this to women’s longer average life expectancy.
Sciensano Reports First Quantification of BMI-Related Mortality in Belgium
Regional data across Belgium’s territory reveal stark differences in obesity-related death rates. The southern region of Wallonia reported the highest rate, with 95.21 deaths per 100,000 residents. The Brussels-Capital Region followed, with an age-standardized rate of 85 per 100,000. Flanders had the lowest impact, recording 73.60 deaths per 100,000 residents. Public health experts note these regional disparities likely reflect socioeconomic factors, dietary habits, and healthcare access across Belgium’s regions.
This data release coincides with ongoing policy reviews led by the Federal Public Service Health, which manages national health initiatives. Officials are using these insights to evaluate the long-term economic pressures on healthcare caused by chronic diseases. The methodology involved calculating the population attributable fraction for each health condition, establishing baseline estimates to inform future prevention strategies.
Over Two Thousand Deaths in Belgium Linked to Coronary Heart Disease
On a European scale, agencies such as the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to coordinate regional policies. The Belgian report aligns with broader EU health goals aimed at reducing early deaths from non-communicable diseases. The World Health Organization’s guidelines continue to advocate comprehensive strategies, including public education, nutritional labeling, and early clinical intervention, to address these risks.
These findings provide a factual basis for health authorities working to lower BMI-related mortality in Western Europe. By quantifying both death counts and years of life lost, policymakers can better allocate resources for screening, intervention, and lifestyle programs. As regional and national health bodies analyze this data, there is an increasing emphasis on early preventative measures to curb chronic disease prevalence across Belgium and beyond.
