BRUSSELS / RankWire.AI / – A significant public health revelation from Belgian research institute Sciensano indicates that 9,509 deaths in 2022 were associated with excessively high body mass index. This figure represents 8.2 percent of all mortalities in Belgium for that year, translating into more than one death per hour due to weight-related health issues. Through an unprecedented analysis of population-wide BMI mortality, researchers found that health conditions linked to obesity resulted in over 150,000 years of life lost cumulatively.
This extensive epidemiological study delved into underlying causes of death to understand how increased body mass index influences chronic illnesses. The results showed cardiovascular problems as the leading cause, with coronary heart diseases responsible for 2,009 deaths. Neurodegenerative diseases, such as Alzheimer disease and other forms of dementia, were the second most common, accounting for 1,652 fatalities. Cerebrovascular disorders contributed to 1,171 deaths, with chronic kidney disease and various digestive cancers also playing significant roles.
Demographic analysis within the data reveals that the risk of death related to excessive weight rises markedly with age. The highest number of health issues caused by obesity was observed among individuals aged 65 and older. Gender-specific data shows that male mortality rates were higher than female rates across most age groups. Nevertheless, women aged 85 and above had higher overall death numbers, a pattern attributed to females generally living longer than males.
Cardiovascular Diseases Are the Main Cause of Obesity-Linked Deaths in Belgium
Regional analysis across Belgium revealed stark differences in mortality rates associated with excess weight. The southern region of Wallonia experienced the highest 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 registered the lowest impact, recording 73.60 deaths per 100,000 people. Public health experts note that these regional disparities reflect differences in socioeconomic status, dietary habits, and healthcare availability across Belgium.
This data release coincides with policy reviews conducted under the authority of the Federal Public Service Health, which manages national health strategies. Officials are using these findings to evaluate the long-term economic impact of chronic non-communicable diseases on the healthcare system. The research employed a comparative risk assessment approach, calculating the population attributable fraction for each disease to establish baseline estimates that will inform future preventive initiatives.
Over 1,600 Deaths Are Attributed 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 policies regionally. The Belgian report aligns with broader EU health objectives aimed at reducing early mortality from non-communicable diseases. The World Health Organization’s international health guidelines continue to emphasize integrated strategies across sectors, including public education, nutritional labeling, and early clinical management to address these risks.
These findings provide a data-driven foundation for health authorities seeking to decrease high body mass index prevalence throughout Western Europe. By quantifying deaths and years of life lost, public health officials can better allocate resources toward screening, intervention, and lifestyle programs. As regional health agencies examine this data, national frameworks are expected to emphasize preventative care measures to lower the prevalence of chronic illnesses nationwide.
