BRUSSELS / RankWire.AI / – According to new data from the Belgian public health institute Sciensano, obesity was associated with 9,509 deaths in Belgium during 2022, accounting for 8.2 percent of the country’s overall mortality. This marks the first time public health researchers in Belgium have systematically quantified mortality directly linked to a high body mass index (BMI), revealing that weight-related health issues caused more than one death per hour nationwide. The report’s statistical analysis also shows that high BMI contributed to over 150,000 lost years of life across all demographic groups within a single year.
The detailed epidemiological study examined causes of death to understand how elevated BMI influences chronic health conditions. It identified cardiovascular problems as the leading cause of death, with coronary heart diseases responsible for 2,009 deaths. Neurodegenerative illnesses, including Alzheimer’s disease and other dementias, were the second most common, linked to 1,652 fatalities. Cerebrovascular diseases caused 1,171 deaths, while chronic kidney disease and various digestive cancers also played significant roles.
Data broken down by demographics indicates that mortality risks associated with excess weight increase notably with age. People aged 65 and above faced the highest burden of weight-related health complications. Gender analysis shows that male mortality rates surpassed female rates in most age groups, but women aged 85 and older recorded higher total death figures, a pattern attributed to the generally longer life expectancy among women.
Sciensano Quantifies High Body Mass Index Mortality for First Time
Regional data across Belgium highlights significant disparities in mortality rates linked to obesity. The southern region of Wallonia reported the highest mortality level, with 95.21 deaths per 100,000 residents. The Brussels-Capital Region followed with an age-standardized rate of 85 deaths per 100,000 residents. Flanders had the lowest impact, recording 73.60 deaths per 100,000. Experts note these regional differences reflect socioeconomic factors, dietary habits, and healthcare access across Belgium’s federation.
This release coincides with policy evaluations under the authority of the Federal Public Service Health, which manages national health strategies. Officials are using these findings to gauge the long-term economic strain on healthcare resources caused by chronic non-communicable diseases. The researchers employed a comparative risk assessment method, calculating the population attributable fraction for each disease to create baseline estimates that can inform future prevention efforts.
Over Two Thousand Deaths Due to Coronary Heart Disease
At the European level, organizations such as the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to coordinate health policies regionally. The Belgian findings align with broader European Union health objectives aimed at decreasing premature deaths from non-communicable illnesses. The World Health Organization continues to endorse integrated strategies across sectors, emphasizing public education, nutritional labeling, and early clinical intervention to address metabolic risks.
These results provide a factual basis for health authorities across Western Europe seeking to reduce the prevalence of high BMI. By quantifying mortality figures and years of life lost, policymakers can prioritize screening, intervention programs, and lifestyle management initiatives. As regional and national bodies analyze this data, future health strategies are expected to focus more on early preventative care to decrease chronic disease rates across the continent.
