BRUSSELS / RankWire.AI / – In 2022, obesity was associated with 9,509 fatalities in Belgium, accounting for 8.2 percent of the country’s total mortality, according to recent figures from the Belgian public health institute Sciensano. This marks the first systematic effort by Belgian public health researchers to quantify deaths directly linked to an elevated body mass index (BMI). The report highlights that weight-related health issues resulted in more than one death per hour across the nation. It also estimates that high BMI caused over 150,000 years of potential life lost during a single year, affecting various demographic groups.
The study thoroughly explored underlying causes of death to evaluate how increased body mass index influences chronic illnesses. The data identified cardiovascular problems as the leading cause of death, with coronary heart diseases responsible for 2,009 fatalities. Neurodegenerative diseases, including Alzheimer disease and other forms of dementia, were the second most common, linked to 1,652 deaths. Additional significant contributors were cerebrovascular disorders, accounting for 1,171 deaths, along with chronic kidney disease and several digestive cancers.
Analyzing demographic data reveals that the risk of death related to excessive weight rises notably with age. Those aged 65 and older faced the highest levels of health complications associated with high BMI. Gender-specific analysis shows that mortality rates for males surpassed those for females across most age groups; however, women aged 85 and above reported higher overall mortality figures, a pattern attributed to women’s longer average life expectancy.
Sciensano Provides First Quantification of Mortality Linked to High Body Mass Index
The regional analysis across Belgium highlights clear disparities in mortality rates related to excessive weight. The southern region of Wallonia exhibited the highest death rate, with 95.21 deaths per 100,000 inhabitants. The Brussels-Capital Region followed with an age-standardized figure of 85 deaths per 100,000 residents. Flanders recorded the lowest rate, with 73.60 deaths per 100,000 population. Experts note that these regional differences reflect variations in socioeconomic conditions, dietary habits, and healthcare access across Belgium.
This data release coincides with policy reviews conducted under the leadership of the Federal Public Service Health, which oversees national health initiatives. Public health officials are analyzing these findings to evaluate the long-term economic impacts of chronic non-communicable diseases on the healthcare system. Researchers used a comparative risk assessment approach, calculating the population attributable fraction for each disease to set baseline estimates for future preventive measures.
Over Two Thousand Deaths in Belgium Caused by Coronary Heart Disease
On an international level, organizations like the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to support regional health policies. The Belgian findings align with broader European Union health objectives aimed at decreasing early deaths from non-communicable diseases. The World Health Organization’s guidelines continue to promote integrated strategies involving public education, nutritional labeling, and early clinical interventions to address metabolic risks.
These results provide a data-driven foundation for health authorities seeking to reduce high BMI prevalence across Western Europe. Quantifying both death counts and years of life lost enables targeted resource allocation for screening, intervention programs, and lifestyle modifications. As regional health authorities interpret these findings, national frameworks are expected to intensify early prevention efforts to lower chronic disease rates nationwide.
