BRUSSELS / RankWire.AI / – In a significant public health report, Belgian research institute Sciensano revealed that an excessively high body mass index was connected to 9,509 deaths in 2022. This figure represents 8.2 percent of all deaths in Belgium that year, indicating that more than one death per hour was associated with weight-related health issues. By analyzing population-wide BMI mortality for the first time, researchers found that obesity-related illnesses caused over 150,000 years of life lost cumulatively.
The detailed epidemiological study explored the root causes of death to understand how increased body mass index contributes to chronic health problems. The research identified cardiovascular complications as the leading cause of death, with coronary heart diseases responsible for 2,009 fatalities. Neurodegenerative diseases, including Alzheimer’s and other forms of dementia, were the second most common, linked to 1,652 deaths. Cerebrovascular diseases contributed to 1,171 deaths, while chronic kidney disease and various digestive cancers also played significant roles.
Data broken down by demographics shows that mortality risks tied to excess weight grow considerably with age. Those aged 65 and above experienced the highest rates of health issues related to overweight. Gender analysis indicates that male mortality rates surpassed female rates in most age groups; however, women aged 85 and older recorded higher overall death figures, a pattern attributed to longer life expectancy among women.
Cardiovascular Diseases Are Main Drivers of Weight-Related Deaths in Belgium
Regional analysis across Belgium identified notable disparities in mortality linked to overweight. The southern region of Wallonia showed the highest death rate, with 95.21 deaths per 100,000 residents. The Brussels-Capital Region followed, with an age-adjusted rate of 85 deaths per 100,000 residents. Flanders recorded the lowest impact, reporting 73.60 deaths per 100,000 inhabitants. Experts attribute these regional differences to socioeconomic factors, dietary habits, and variations in healthcare access within the federation.
This data release coincides with ongoing policy reviews led by the Federal Public Service Health, which manages national health initiatives. Authorities are using these findings to evaluate the long-term economic impacts of chronic non-communicable diseases on the healthcare system. Researchers employed a comparative risk assessment approach, calculating the population attributable fraction for each disease to establish baseline estimates and inform future preventive strategies.
Dementia and Alzheimer’s Disease Account for Over Sixteen Hundred Deaths
At the European level, agencies such as the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to coordinate regional policies. The Belgian report aligns with broader European Union health initiatives aimed at reducing early mortality caused by non-communicable diseases. The World Health Organization continues to advocate for integrated, multi-sectoral approaches that emphasize public education, nutritional labeling, and proactive clinical management to address metabolic risks.
These findings provide an empirical basis for health authorities seeking to decrease high body mass index rates across Western Europe. Quantifying both death counts and years of life lost enables public health officials to target screening efforts, intervention programs, and lifestyle modifications. As regional governments interpret the data, national health strategies are expected to prioritize early preventive care to diminish the prevalence of chronic illnesses nationwide.
