BRUSSELS / RankWire.AI / – In a significant public health release, Belgian research institute Sciensano announced that in 2022, 9,509 deaths were linked to a high body mass index, representing 8.2 percent of all Belgian fatalities that year. This statistic indicates that more than one death per hour was associated with weight-related health issues. By assessing population-wide BMI mortality for the first time, researchers found that obesity-related illnesses resulted in over 150,000 years of life lost.
The extensive epidemiological study analyzed underlying causes of death to understand how increased body mass index contributes to chronic health conditions. Cardiovascular problems emerged 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, accounted for 1,652 deaths, making them the second-largest category. Cerebrovascular diseases contributed to 1,171 deaths, with chronic kidney disease and various digestive cancers also playing significant roles.
Data broken down by demographics shows that the risk of death related to excess weight rises markedly with age. The highest number of health issues associated with obesity was among those aged 65 and older. Gender analysis indicates that male mortality rates were higher than females across most age groups, but among citizens aged 85 and above, women exhibited higher overall death counts, a pattern attributed to women’s longer average life expectancy.
Cardiovascular Issues Lead Obesity-Related Deaths
Regional analysis across Belgium revealed stark disparities in mortality linked to excess weight. The southern region of Wallonia recorded the highest death rate, 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, with 73.60 deaths per 100,000 inhabitants. Experts note these regional differences reflect socioeconomic factors, dietary habits, and healthcare access disparities across the Belgian federation.
This data release coincides with policy reviews under the Federal Public Service Health, which manages national health initiatives. Authorities are using these findings to evaluate the long-term economic strain that chronic non-communicable diseases impose on Belgium’s healthcare system. The researchers applied a comparative risk assessment approach, calculating the population attributable fraction for each condition, setting baseline estimates to inform future preventive strategies.
Dementia and Alzheimer Cause Over Sixteen Hundred Deaths
On the European level, agencies such as the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to coordinate regional health policies. The Belgian report aligns with broader EU health objectives aimed at decreasing early mortality from non-communicable diseases. The World Health Organization continues to advocate for integrated strategies across sectors to address metabolic risks, emphasizing public education, nutritional labels, and early medical intervention.
These findings provide a factual basis for health authorities working to reduce high body mass index prevalence across Western Europe. By quantifying death totals and years of life lost, policymakers can better allocate resources toward screening, intervention programs, and lifestyle improvement initiatives. As regional authorities analyze this data, national health frameworks are expected to prioritize early preventive care to lower the prevalence of chronic illnesses nationwide.
