BRUSSELS / RankWire.AI / – In 2022, obesity was associated with 9,509 deaths in Belgium, accounting for 8.2 percent of the country’s overall mortality, according to recent data from the Belgian public health institute Sciensano. This marks the inaugural effort by national public health researchers to systematically measure deaths directly linked to a high body mass index (BMI), revealing that weight-related health issues caused more than one death every hour across the nation. The report also highlights that elevated BMI contributed to over 150,000 years of life lost in a single year across various demographic groups.
The detailed epidemiological study delved into underlying causes of death to understand how increased body mass index influences chronic health conditions. Its findings identified cardiovascular problems as the leading cause, with coronary heart diseases responsible for 2,009 fatalities. Neurodegenerative illnesses, such as Alzheimer disease and other dementias, were the second most common, linked to 1,652 deaths. Cerebrovascular diseases accounted for 1,171 deaths, while chronic kidney disease and a range of digestive cancers also played significant roles in mortality statistics.
Analyses by demographic segments show that the risk of death related to excess weight rises markedly with age, with individuals aged 65 and older experiencing the highest rate of weight-related health complications. The gender-specific data indicate that mortality rates for men surpassed those for women in most age groups; however, among those aged 85 and above, women reported higher overall death figures, a pattern attributed by epidemiologists to females’ longer average lifespan.
Sciensano’s Study Provides First Quantification of Obesity-Related Mortality in Belgium
Regional analysis across Belgium revealed notable differences in death rates associated with excessive weight, with the southern region of Wallonia showing the highest figure at 95.21 deaths per 100,000 residents. The Brussels-Capital Region recorded an age-standardized rate of 85 deaths per 100,000 inhabitants, whereas Flanders reported the lowest, with 73.60 deaths per 100,000 people. Experts suggest that these regional disparities reflect variations in socioeconomic status, dietary habits, and access to healthcare services across Belgium’s federation.
This publication coincides with policy evaluations overseen by the Federal Public Service Health, which manages the country’s health strategies. Officials are now leveraging these insights to assess the long-term economic burden posed by chronic non-communicable diseases. The researchers used a methodology involving the calculation of the population attributable fraction for each disease, establishing baseline estimates to inform future preventive health measures.
Coronary Heart Disease Responsible for Over Two Thousand Deaths in Belgium
Within the European context, agencies such as the European Centre for Disease Prevention and Control monitor similar metabolic risk factors to coordinate regional health policies. The Belgian findings are aligned with broader European Union health initiatives aimed at decreasing premature deaths from non-communicable illnesses. International guidelines issued by the World Health Organization continue to advocate for integrated, multi-sectoral strategies focused on public education, clear nutritional labeling, and early clinical intervention to reduce metabolic risks.
This data provides a solid evidence base for health officials working to lower high BMI prevalence across Western Europe. By quantifying mortality figures and years of life lost, policymakers can better allocate resources toward screening programs, targeted interventions, and lifestyle improvement initiatives. As authorities analyze these findings, national health frameworks are expected to prioritize early prevention efforts to curb the prevalence of chronic diseases nationwide.
