Young diabetics in Korea double in 10 years: study
The number of Koreans in their 20s and 30s diagnosed with Type 2 diabetes has more than doubled in a decade, with approximately 370,000 people in this age group now living with the disease, a recent study shows.
According to research published in the Diabetes and Metabolism Journal of the Korean Diabetes Association, 2.02 percent of Koreans aged 19-39 had Type 2 diabetes in 2020, up from 1.02 percent in 2010. The increase of diabetes cases among young adults is especially noticeable among those in their 30s, where the rate increased from 2.9 percent to 3.9 percent in the same period.
Type 2 diabetes refers to a chronic condition characterized by high blood sugar levels stemming from the body's inability to use insulin correctly, which can eventually cause damage to the eyes, kidneys, nerves and heart. Obesity and lack of physical exercise are among factors linked to diabetes, along with family history, poor diet and certain medications.
The researchers found that a significant number of those with Type 2 diabetes had a high body mass index. Some 67.8 percent of young adults with diabetes here had a BMI of 25 kilograms per square meter, while 31.6 percent had a BMI of at least 30. BMI is calculated by dividing a person's weight (in kg) by their height in meters squared.
A substantial number of young adults with diabetes also had other metabolic conditions, including dyslipidemia (79.8 percent), fatty liver (78.9 percent) and high blood pressure (34.2 percent). Several cases of heart-related diseases were also found in diabetic patients in the 19-39 age group.
Researchers noted that the recent rise of Type 2 diabetes among young adults here reveals a need for government attention, such as programs tailored specifically for young vulnerable groups and systems to support those with obesity.
South Korea has recently seen increases in the diabetes prevalence rate. The Health and Insurance Review and Service report in November revealed that 7.46 percent of the population, or 3.82 million, have diabetes. The number of people with diabetes here increased by 18.6 percent between 2019 and 2023, with male patients rising by 19.6 percent and female patients by 17.3 percent in the same period.
Despite the rising number of people with diabetes in their 20s and 30s, studies have shown that only one-third of such cases are being treated. According to the Diabetes Fact Sheet 2024 by the Korean Diabetes Association, 35 percent of diabetes patients in their 20s and 30s were receiving treatment.

South Korea pays just a quarter of US drug prices: report
Prescription drug prices in South Korea are among the lowest in the developed world, with Koreans paying just 25.6 percent of what Americans pay on average for the same medicines, according to new data released by the Korea Biotechnology Industry Organization. The analysis, published Monday by KoreaBIO's Bio-Economic Research Center, compares 2022 prescription drug prices across 33 OECD member countries. Based on a February 2024 study by the RAND Corporation, supported by the US Department of Health and Human Services and using IQVIA MIDAS data, the report confirms what many in the industry have long suspected: South Korea remains one of the most affordable countries in the world for pharmaceuticals. On average, drug prices in the US are 3.9 times higher than in South Korea. For brand-name drugs, the gap grows to 7 times. Among the top 60 revenue-generating medicines in the US, prices are 8.4 times higher. Biologics are also significantly more expensive, costing over 5.7 times more than in Korea. The report also highlighted US price premiums over other major markets: 3.5 times higher than Japan, 3.3 times higher than France, 2.9 times higher than Germany, and 2.7 times higher than the United Kingdom. Turkey showed the greatest disparity, with US drug prices more than 10 times higher than those in Turkey. The report comes days after US President Donald Trump issued letters to 17 global pharmaceutical firms demanding that they lower US prices to match the 'most favored nation' level, referring to the lowest price charged in any OECD country. The companies have been given a 60-day deadline to respond.

10 deaths a day as S. Korea's suicide fight falls short among seniors
With few visible signals, more fatal methods, senior suicides underscore need for tailored mental health interventions, report finds An average of nearly 10 older South Koreans died by suicide every day between 2019 and 2023, according to a sobering new report that underscores the growing mental health crisis among the country's aging population. In total, 18,044 seniors aged 65 and older took their own lives during that five-year period, amounting to over 3,000 deaths each year, the report said. The findings, published in the Journal of the Korean Medical Association and authored by Dr. Oh Dae-jong of the Workplace Mental Health Institute at Kangbuk Samsung Hospital, point to the urgent need for improved suicide prevention efforts targeting vulnerable seniors in South Korea. In 2023 alone, the suicide mortality rate — the number of deaths per 100,000 people —stood at 40.6 among seniors, 45 percent higher than the rate of 28 observed among people aged 15 to 64. "Older adults are less likely than younger people to seek psychiatric help before attempting suicide, and many take their own lives after only one or a few attempts, making early identification of high-risk seniors important," Oh wrote in the report. Depression in older adults is often driven by factors such as the loss of a spouse, financial stress, loneliness, family conflict as well as a lingering sense of guilt over being a burden on their families — all of which can deepen suicidal thoughts. Alongside mental health conditions, chronic physical illnesses are also major contributors to suicide among older adults. The risk of suicide rises significantly in the period shortly after a diagnosis. Compared to younger people, older adults tend to use more fatal means of suicide, such as ingesting pesticides or hanging, making survival much less likely. 'It is essential to have trained gatekeepers across the medical field who can identify and respond to early verbal, emotional and behavioral warning signs in older adults at risk of suicide. Effective suicide prevention requires a comprehensive, collaborative strategy between health professionals and the community," the report stressed. Meanwhile, the country's senior population surpassed the 10 million mark for the first time last November, reaching 10.12 million, an increase of 513,000 from a year earlier, according to Statistics Korea. Older adults now account for 19.5 percent of the total population of 51.81 million, up from 18.6 percent the previous year, indicating that some 1 in 5 Koreans are now 65 or older.

Koreans may have to pay as much as 25% of income for health benefits by 2072: report
Increasing medical costs due to population aging likely to lead to bigger financial burden South Koreans' financial burden for maintaining the National Health Insurance Service could rise to a quarter of income due to population aging and increasing life expectancy, a study showed Sunday. The study, carried out by Seoul National University's Tech-biz Innovation Platform, estimated the financial impact of population aging on the state-run health insurance. As of last year, South Korea officially became a "superaged" society by the United Nations' definition, as one out of every five Koreans was at least 65. The team derived three possible scenarios, and the most probable of the three showed the mandated insurance rate for those employed full-time for at least one month — currently sitting at 7.09 percent, split between employer and employee — would rise to 10.04 percent by 2035, 15.81 percent by 2050, and to 25.09 percent by 2072. The Ministry of Health and Welfare sets the rate for the state-run health insurance program annually as a proportion of income. The rate was frozen for the third straight year in 2025, but had risen consistently since 5.33 percent in 2010. Researchers noted that this was a conservative estimate, which did not factor in possibilities such as a rise in the cost of medical services or a decrease in general wages due to economic slump. The study was commissioned by the Presidential Committee on Aging Society and Population Policy, which is under the presidential office, but is mainly handled by the Health Ministry. Health fees projected to skyrocket in 'super-aged' Korea The NHIS is part of the country's public health safety net, to which all Koreans and many foreigners are mandated to subscribe. The legal limit for the insurance rate is 8 percent of income, but there is an ongoing discussion about raising the cap. With more senior citizens in the country than ever before, the ratio of the current health expenditure to gross domestic product has been consistently rising. It was 2.6 percent of the GDP throughout the 1970s, according to the Health Ministry, but it has climbed to 7.9 percent in 2020 and to 9.2 percent in 2023. Advances in modern medicine have extended life expectancy, but the ongoing slump in total fertility rate — the number of children a woman is expected to have during her lifetime — has resulted in an overall aging population. The total fertility rate for 2024 inched up slightly to 0.75 from 0.72 in 2023, but it was still the lowest figure among the members of the Organization for Economic Cooperation and Development. The NHIS sets aside a portion of premiums to cover elderly medical fees, which is currently set at 0.91 percent of each subscriber's income. This rate is expected to steeply climb to 1.95 percent by 2035, 5.84 percent by 2050, and 13.97 percent by 2072, which would be over 15 times the figure in 2025. The number of senior citizens needing long-term care is also expected to spike in that time, from 7.14 percent of the population in 2023 to 16.4 percent by 2072. "Without a sustainable national health insurance program and the long-term care insurance program, the social security system will weaken and lead to the deteriorated quality of life for seniors in the superaged society," the researchers noted. Possible responses to this issue include expanding senior care services alongside systemic changes to more effectively manage health-related spending. The study also suggested an adjustment in the legal definition of the "senior citizen," which is set at 65.
