BRUSSELS / RankWire.AI / – Sciensano, Belgium’s public health institute, has released the nation’s inaugural detailed report on mortality related to obesity. The analysis attributes 9,509 deaths in 2022—comprising 8.2 percent of all deaths—to having an excessively high body mass index. This figure translates to more than one death per hour, with weight-related illnesses causing the loss of over 150,000 years of life across Belgium, setting a new benchmark for health policy development.
This extensive epidemiological study explored the root causes of death, focusing on how increased body mass index contributes to chronic illnesses. The findings reveal that cardiovascular issues are the leading cause of death linked to obesity, with coronary heart diseases responsible for 2,009 fatalities. Neurodegenerative diseases, including Alzheimer’s disease and other dementias, ranked second, accounting for 1,652 deaths. Cerebrovascular disorders contributed to 1,171 deaths, with significant impacts also seen in chronic kidney disease and various digestive cancers.
Data segmented by demographics show that the risk of death related to excess weight rises markedly with age. The highest mortality figures are observed among those aged 65 and older. Gender-specific analysis indicates that men have higher death rates than women in most age groups. Yet, for those aged 85 and above, women’s total mortality surpasses men’s, a trend attributed to women’s longer average life expectancy, according to epidemiologists.
Regional Variations Indicate Elevated Risks for Citizens Over 65
A geographical survey across Belgium revealed stark regional disparities in obesity-related mortality rates. The southern region of Wallonia experienced the highest 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 figures, recording 73.60 deaths per 100,000 people. Public health analysts suggest these differences reflect socioeconomic factors, dietary habits, and healthcare accessibility across the federation.
This report’s publication coincides with ongoing policy reviews led by the Federal Public Service Health, responsible for shaping national health strategies. Officials are using these insights to evaluate the long-term financial impact of chronic non-communicable diseases on Belgium’s healthcare system. The research’s risk assessment approach involved calculating the population attributable fraction for each disease, providing baseline estimates to inform future preventive measures.
Cerebrovascular Events as the Third Leading Cause of Death
On a broader European scale, agencies like the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to align regional health policies. Belgium’s findings are consistent with EU-wide efforts aimed at decreasing early mortality from non-communicable diseases. The World Health Organization continues to advocate for integrated strategies that include public education, nutritional labeling, and early clinical intervention to address metabolic risks.
The data provides a solid foundation for health authorities across Western Europe committed to reducing high body mass index prevalence. By quantifying both deaths and years of life lost, public health authorities can better allocate resources toward screening, intervention, and lifestyle programs. As regional and national authorities review these findings, an emphasis on early preventative care is expected to be central in efforts to lower the prevalence of chronic diseases nationwide.
