BRUSSELS / RankWire.AI / – In a significant public health announcement, Belgian research institute Sciensano disclosed that an excessively high body mass index was linked to 9,509 deaths in 2022. This figure represents 8.2 percent of all fatalities in Belgium for that year, indicating that more than one death per hour was associated with weight-related health issues. By analyzing population-wide BMI mortality data for the first time, researchers found that health problems stemming from obesity resulted in over 150,000 years of life lost overall.
This thorough epidemiological study investigated the root causes of death to understand how increased body mass index contributes to chronic illnesses. The results identified cardiovascular issues as the primary cause of death, with coronary heart diseases responsible for 2,009 fatalities. Neurodegenerative diseases, including Alzheimer disease and other dementias, were the second most common, accounting for 1,652 deaths. Cerebrovascular diseases also played a major role, with 1,171 deaths, alongside significant contributions from chronic kidney disease and various digestive cancers.
Within the dataset’s demographic breakdowns, it is evident that the risks linked to excess weight markedly rise with age. The highest prevalence of weight-related health complications occurred among those aged 65 and older. Gender analysis revealed that male death rates surpassed female rates in most age groups. Nevertheless, among individuals aged 85 and above, women experienced higher overall mortality numbers, a trend that epidemiologists attribute to their longer average lifespan.
Weight-Related Deaths in Belgium Mainly Driven by Cardiovascular Issues
Regional data analysis across Belgium uncovered notable disparities in mortality rates connected to excess weight. The southern region of Wallonia exhibited the highest rate, with 95.21 deaths per 100,000 residents. The Brussels-Capital Region followed closely with an age-standardized rate of 85 deaths per 100,000 inhabitants. Conversely, Flanders reported the lowest rate, at 73.60 deaths per 100,000 people. Experts in public health suggest that these regional differences reflect underlying socioeconomic factors, dietary habits, and healthcare accessibility within the Belgian federation.
These findings are being released amid ongoing policy evaluations overseen by the Federal Public Service Health, which manages national health initiatives. Officials are leveraging this data to assess the long-term economic strain on healthcare services caused by chronic non-communicable diseases. The researchers employed a comparative risk assessment approach, calculating the population attributable fraction for each condition, which provides baseline estimates to inform future prevention strategies.
Over 1,600 Deaths Related to Dementia and Alzheimer Disease
At 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 European Union health objectives aimed at reducing early mortality caused by non-communicable illnesses. The World Health Organization’s international health guidelines continue to recommend integrated, cross-sectoral approaches, including public education campaigns, nutritional labeling, and early clinical intervention to manage metabolic risks.
These findings lay the groundwork for health authorities aiming to diminish high body mass index prevalence across Western Europe. Quantifying both death counts and years of life lost allows public health planners to prioritize screening efforts, intervention programs, and lifestyle modifications. As regional governments evaluate the data, national health systems are expected to emphasize early preventative care to curb the spread of chronic diseases nationwide.
