BRUSSELS (AP) — A recent study reveals a concerning trend in Belgium: an increase in chronic diseases, particularly among younger adults, a surge in depression rates among young people, and a growing number of belgians reporting oral health problems.
Multimorbidity on the Rise
Public health researcher Rana Charafeddine at Sciensano noted a notable increase in multimorbidity – the presence of two or more chronic diseases – among adults. “In 2018, 31% of people aged 25 to 44 reported at least two chronic diseases, compared to 33.4% in 2023. A similar trend was observed for 45- to 64-year-olds, with the rate increasing from 53% to 58%,” Charafeddine said.
Data from 2023-2024 indicates that over half of Belgians aged 45 to 54 are already experiencing multimorbidity. Moreover, among those aged 25 to 34, more than 45% of women and nearly 35% of men are affected.
Allergies, Back Pain, and Hypertension Common
The most prevalent chronic conditions include allergies, back pain, osteoarthritis, and hypertension. Since 2001, the percentage of Belgians suffering from allergies (including hay fever, dust mite allergies, and contact allergies) has doubled, climbing from 13.9% to 25.3%. Similarly, the prevalence of diabetes has risen from 3.4% to 6.9% during the same period. Sciensano suggests these figures may underestimate the true extent of these conditions.
while rates of back problems and osteoarthritis have remained relatively stable as 2018, they continue to affect a significant portion of the population, with approximately 25% and 19% of individuals aged 15 and over reporting these conditions, respectively.
Hypertension affects 16% of Belgians aged 15 and older, with the rate climbing to 44% among those aged 75 and older. This condition rounds out the top four most frequent chronic diseases in both men and women.
The most common combinations of chronic conditions are back and neck pain combined with joint disease, and back and neck pain combined with allergies.
Depression Doubles Among Young Adults
While the prevalence of depression has remained stable or slightly decreased among older adults,there has been a significant increase among young people,particularly those aged 15 to 24. Between 2018 and 2023-2024, the rate of depression in this age group doubled, rising from 3.0% to 6.7% across all regions.
Among the population aged 15 and over, 8.1% reported experiencing depression in the past year, while 6.6% reported generalized anxiety. Additionally, 3.1% of individuals in this age group reported suffering from both conditions concurrently.
Generalized anxiety disorder is significantly more prevalent in Wallonia (11.0%) and Brussels (9.2%) compared to flanders (3.8%).A similar trend is observed for depression, with lower prevalence in Flanders (7.0%) than in Brussels (9.5%) and Wallonia (9.7%).
Physical pain a Major Concern
Physical pain is a significant health issue for Belgians aged 15 and over.in 2023-2024,almost one in three people (28%) reported experiencing physical pain,compared to 28% in 2008.
Women are more likely to suffer from physical pain than men, with 38% of women and 25% of men reporting such issues. Back pain is the most frequent type of physical pain for both men (32.2%) and women (26.2%), followed by neck and shoulder pain (12.0% and 15.6%, respectively).
Women aged 55 to 64 report the highest pain scores (38.5) and the highest prevalence of physical pain (46.4%). Those aged 45 to 54 are most often bothered by these pains (43.7%).
Oral Health Problems Affect nearly One in Three
Approximately one in four Belgians perceive their oral health as poor, a proportion that has remained relatively stable since 2018, increasing slightly from 24.0% to 25.8% in 2023-2024.
The number of people who have lost their natural teeth has decreased from 15.9% in 2001 to 9.7% in 2023-2024. the use of removable dental prostheses has also declined, from 28.8% in 2004 to 18.1%. However, the proportion of people reporting oral health problems, such as cavities, periodontal diseases, tooth loss, and mouth cancer, has increased from 13.7% in 2018 to 32.5% in 2023-2024.
Perceptions of oral health vary with age, with 12.1% of 15- to 24-year-olds considering their oral health poor, compared to 33.0% of those aged 75 and over. Oral health perception also varies by education level: 21.4% of senior graduates consider their oral health poor, compared to 36.7% of people without a higher secondary diploma.
