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 new statistics from the Belgian public health institute Sciensano. This marks the first systematic effort by public health researchers in Belgium to quantify deaths directly attributable to a high body mass index (BMI). The report indicates that weight-related health issues caused more than one death every hour across the nation. Additionally, the data reveals that over 150,000 years of life were lost in a single year due to high BMI across all demographic groups.
The detailed epidemiological study explored underlying causes of death to assess how elevated BMI contributes to chronic health conditions. The results showed cardiovascular issues as the leading cause, with coronary heart diseases responsible for 2,009 deaths. Neurodegenerative diseases, such as Alzheimer disease and other dementias, ranked second, linked to 1,652 deaths. Cerebrovascular conditions contributed to 1,171 fatalities, along with notable numbers from chronic kidney disease and various digestive cancers.
Analysis by demographic groups indicates that the risk of death related to excess weight increases significantly with age. Older adults aged 65 and above experienced the highest rates of health problems connected to overweight. Gender-specific data show men generally had higher mortality rates than women across most age groups. However, among those aged 85 and older, women exhibited higher overall death counts, a trend attributed to their longer average lifespan, according to epidemiologists.
Sciensano First Quantifies Mortality Due to Elevated Body Mass Index
Regional analysis across Belgium revealed marked differences in mortality rates linked to excessive weight. The southern region of Wallonia reported the highest level, with 95.21 deaths per 100,000 residents. The Brussels-Capital Region followed, with an age-adjusted rate of 85 deaths per 100,000 inhabitants. Flanders registered the lowest impact, with 73.60 deaths per 100,000. Public health experts suggest these regional disparities reflect socioeconomic factors, dietary habits, and healthcare accessibility across the Belgian federation.
The release of this data coincides with policy reviews led by the Federal Public Service Health, which directs national health strategies. Officials are now using these findings 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 condition to establish baseline estimates and inform future preventive measures.
Over Two Thousand Belgian Deaths Caused by Coronary Heart Disease
At the European level, institutions like the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to coordinate policy efforts across regions. The Belgian report aligns with broader European Union health objectives aimed at reducing early mortality from non-communicable illnesses. The World Health Organization continues to advocate integrated, multi-sector strategies focusing on public education, nutritional labeling, and early clinical interventions to address metabolic risks.
These findings provide an evidence-based foundation for health authorities aiming to lower high BMI prevalence across Western Europe. By quantifying both death counts and years of life lost, public health planners can better allocate resources toward screening, intervention programs, and lifestyle education. As regional and national health agencies analyze this data, federal strategies are expected to emphasize preventative care to diminish chronic disease rates throughout the country.
