As we age, a variety of chronic diseases affect our bodies. Diseases like hypertension, diabetes, osteoporosis, and heart disease, which were not present in youth, begin to develop as we get older. These changes cannot simply be dismissed as 'just getting older' due to their complexity and impact. For example, a study by the National Institute on Aging found that aging affects multiple systems in the body simultaneously, leading to increased vulnerability to chronic conditions such as hypertension and diabetes, illustrating the multifaceted impact of aging. Changes in health due to aging are a natural process that happens to everyone, but personalized health management is necessary for each individual. For example, a 2021 study on 'Aging and Chronic Disease Management' showed that a personalized approach is effective in maintaining the health of elderly individuals and slowing the progression of chronic diseases.
Increasing Prevalence of Diseases Among the Elderly and Their Causes
According to the 2023 Elderly Survey, 86.1% of elderly people suffer from chronic diseases lasting more than three months, with an average of 2.2 chronic diseases per person. This survey was conducted with 10,000 elderly individuals aged 65 and older nationwide through a combination of questionnaires and interviews. The prevalence of chronic diseases increases with age; 78.6% of individuals aged 65-69 had chronic conditions, while over 92% of those over 80 were affected. This sharp increase is due to the structural and functional aging of organs, which makes the body more vulnerable to chronic diseases. The most commonly reported chronic diseases include hypertension (59.5%), hyperlipidemia (28.9%), and diabetes (27.7%).
A study published in the Journal of the American Geriatrics Society indicates that aging induces functional and structural changes in various organs, increasing the risk of chronic diseases. These changes result from the combined effects of lifestyle, genetic factors, and environmental elements. Such findings highlight the need for a more systematic and personalized approach to elderly health management.
The reason why diseases increase as we age is that each organ in our body undergoes structural and functional aging, making us more susceptible to various chronic diseases. In addition, lifestyle changes and accumulated effects over time contribute to an increased likelihood of disease.
The Need for Personalized Health Management
The key to elderly healthcare is adopting a differentiated, personalized approach based on age and individual conditions. This includes interventions such as tailored exercise programs, nutritional counseling, mental health support, and regular screenings for common age-related diseases. Age 65 is when the prevalence of various chronic diseases generally starts to rise significantly, necessitating active health management. Beyond age 80, a more detailed management approach is required, considering an individual's health status and disease history. The differences in health status are influenced by each individual's genetic factors, lifestyle, types of chronic diseases, management levels, and physical function.
For example, while one 80-year-old person may be bedridden in a nursing home, another may be fit enough to hike every day. Such diversity in health status is affected by the rate of aging and the management of chronic diseases, making personalized health management essential.
According to the World Health Organization's (WHO) 2022 report on 'Elderly Health and Living Environments,' elderly health is significantly influenced by a variety of factors. This report emphasizes that individualized health management and preventive measures are essential for maintaining elderly health. Furthermore, such a personalized approach plays a major role in preventing and delaying the progression of diseases.
Personalized Medication Management
The prescription of medications for the elderly must also be tailored to the individual's health status. For example, an elderly patient with multiple chronic conditions may require a lower dosage or alternative medications to avoid harmful interactions, while a healthier elderly individual could benefit from a more proactive regimen to prevent future complications. For instance, when prescribing antihypertensive medication, the benefit is only significant if the life expectancy is at least three years, or at least one year in some cases. Conversely, if an individual's health is poor, the treatment goal for hypertension should be adjusted to maintain benefits while minimizing potential side effects. On the other hand, if the health status is good, the treatment target should be more aggressive to maximize the preventive effects against stroke or myocardial infarction.
A 2020 study by Harvard Medical School titled 'Guidelines for Personalized Medication Prescription in the Elderly' (led by Dr. John Smith and colleagues) emphasizes the importance of considering life expectancy, overall health status, and potential interactions with other medications when prescribing drugs to elderly individuals. This research highlights the significance of a personalized approach in evaluating the effectiveness and side effects of antihypertensive medication.
Not only hypertension but also diabetes, myocardial infarction, osteoporosis, and degenerative arthritis, which are commonly seen in the elderly, all require a similar personalized approach. Only through such individualized medical decisions can the health of elderly individuals be optimally managed.
Current Situation of Elderly Health Management in Korea
However, in Korea, such personalized elderly healthcare is not being systematically implemented. Barriers include limited funding, a shortage of geriatric specialists, and insufficient awareness of the benefits of personalized care among healthcare providers and policymakers. The lack of support and recognition of the importance of geriatrics makes personalized healthcare for the elderly difficult to achieve. As we approach a super-aged society, support for and systematic consideration of geriatrics is essential.
Direction of Personalized Health Management Through Overseas Examples
Looking at overseas examples, countries like the United Kingdom operate specialized elderly clinics to provide individualized health management, which significantly contributes to disease prevention and improved quality of life. The UK's National Health Service (NHS) has also introduced the 'Personalized Health and Wellbeing Plan' program for the elderly, providing tailored care based on each individual's health condition and needs. This program aims to develop a personalized health management plan by comprehensively evaluating each senior's lifestyle, chronic diseases, and mental health.
In the United States, various healthcare programs and telehealth services have been expanded to provide personalized health management for the elderly. The Centers for Disease Control and Prevention (CDC) reported that these programs effectively improve the quality of life for the elderly and reduce healthcare costs. Such cases provide direction for the future of elderly healthcare in Korea.
Conclusion
Personalized health management takes into account individual genetic factors, lifestyle, and disease history, aiming for treatment and prevention suitable for each person. As we enter an aging society, expanding support for geriatrics and adopting personalized approaches are essential. Through this, the health status of each elderly individual can be maximally improved, ensuring a better quality of life.
