There has been a continuous rise in the aged population due to rising life expectancy, with improved healthcare quality, urbanization, and growing income levels leading to greater survival rates. According to the United Nations, there were 727 million people aged 65 years or over globally in 2020. The global share of the aged population (65 years or over) is expected to increase from 9.3% (727 million) in 2020 to 16.0 % (1,548.9 million) by 2050. By 2050, one in four persons living in Europe and North America could be aged 65 years or over. This remarkable growth in the geriatric population is driven by declining fertility rates and improvements in longevity. According to the World Health Organization (WHO), in 2020, for the first time in history, persons aged 65 or above outnumbered children under five globally.
With the rapid growth in the global geriatric population, cases of age-related chronic diseases are expected to increase globally. This demographic shift is leading to the increased prevalence of various chronic diseases. According to the WHO, in 2021, 41 million people died due to chronic diseases, which is equivalent to 74% of deaths all over the world. Cardiovascular diseases account for the majority of chronic disease deaths, which is 17.9 million individuals per year, followed by chronic respiratory diseases (4.1 million), cancers (9.3 million), and other diseases.
Additionally, the elderly population is also affected by cardiovascular diseases (CVD), resulting in increased hospital admissions. For instance, according to the Australian Institute of Health and Welfare (AIHW) National Hospital Morbidity Database, acute care cardiovascular disease hospitalizations increased from 454,653 in 2010-11 to 542,491 in 2020-21. Furthermore, According to the World Health Organization (WHO) 2021 data, in 2019, 17.9 million people died from cardiovascular diseases, representing 32% of deaths all over the world, and 85% were due to stroke and heart attack. For diagnosis of CVDs, chest X-rays of the patients are widely preferred.
Breast cancer is also one of the most prevalent diseases. X-ray imaging is commonly used for the diagnosis of breast cancer. This diagnosis is known as mammography. The adoption of this diagnosis is expected to increase with the rise in breast cancer cases. According to GLOBOCAN 2020, it is estimated that new breast cancer cases will reach 2.7 million cases by 2030 from 2.4 million in 2020. Thus, the rising geriatric population and the burden of chronic diseases are expected to boost the adoption of digital X-ray systems.
Dental caries, also known as tooth decay, is the most prevalent non-communicable disease (NCD) that affects all age groups. According to Global Burden of Disease 2019, untreated dental caries in permanent teeth is the most common health condition observed. Globally, it is estimated that 2 billion people suffer from caries of permanent teeth, and 520 million children suffer from caries of primary teeth (source: WHO). In the diagnosis of dental problems, dental X-rays are used to evaluate dental issues. As tooth decay may not be visible during an oral examination, intraoral X-rays are commonly used. Thus, the high prevalence of dental problems is also expected to drive market growth.
The rising geriatric population, coupled with the growing burden of chronic diseases. This is expected to drive the global digital X-ray systems market at a CAGR of 7.8% to reach $13.29 billion by 2030, according to Meticulous Research®.
