A new long-term health dataset is giving researchers a closer look at how Korean students’ health habits and wellbeing change as they move from elementary school into high school.
The Korea Disease Control and Prevention Agency (KDCA) released new raw data Tuesday from its sixth annual Youth Health Panel Survey, which follows the same group of students over several years rather than relying only on one-time snapshots.
The study began in 2019 with 5,051 sixth-grade students. By 2024, 4,141 students — about 82 percent of the original cohort — remained in the study, reaching their second year of high school. The cohort is scheduled to be followed through high school graduation in 2028.
What Changes as Students Get Older?
The latest dataset contains 29 core health indicators covering five major areas: diet, physical activity, tobacco use, alcohol consumption and general illness.
Researchers also added measures for smartphone overdependence and high-caffeine energy-drink consumption, reflecting newer concerns surrounding adolescent lifestyles.
The survey identifies frequent energy-drink consumption as three or more times per week. Among the findings highlighted by the agency, frequent energy-drink intake and smartphone overdependence emerged as notable health-related risks among students in their second year of high school.
The longitudinal dataset also tracks changes involving exercise, sleep and exposure to cigarettes, e-cigarettes and alcohol, alongside self-reported stress and depression indicators. Because the same cohort is followed over time, researchers can examine how behaviors and experiences change as students move through adolescence.
Why the Long-Term Data Matters
The release gives researchers access to anonymized information that can be analyzed across medicine, statistics, economics and other fields.
The agency said the goal is to help researchers study youth health from a developmental perspective, rather than examining isolated measurements from different groups of students.
The data release follows an August symposium where researchers presented 95 studies based on the survey’s first five years of information.
KDCA Director Lim Seung-kwan said the continued release of the dataset is intended to support evidence-based policies addressing youth health.
The findings come as Korean students navigate increasingly demanding academic years, but the dataset itself does not establish that academic pressure alone causes the health changes observed. Instead, it provides researchers with a detailed record of multiple lifestyle, environmental and behavioral factors that can be studied over time.
With the cohort continuing to be tracked until 2028, researchers will have more data to examine as these students move toward adulthood.
The bigger question now is what the next stages of the study will reveal — and whether the warning signs identified during adolescence will lead to measurable changes in how Korea approaches youth health.
