Health screening provides information on disease risk and diagnosis, but whether this promotes health is unclear. We estimate the impacts of information provided by Korea's National Health Screening Program by applying a regression discontinuity design around different biomarker thresholds of diabetes, obesity, and hyperlipidemia risk using administrative data that includes medical claims, biomarkers, and behavioral surveys over four years after screening. Generally, we find limited responses to disease risk information alone. However, we find evidence for weight loss around the high risk threshold for diabetes, where information is combined with active prompting for a secondary examination for diagnosis and treatment.
健康筛查提供了有关疾病风险和诊断的信息，但这是否能促进健康尚不清楚。我们利用包括医疗索赔、生物标志物和行为调查在内的四年筛查后行政数据，通过在糖尿病、肥胖症和高血脂风险的不同生物标志物阈值附近应用回归不连续性设计，估计韩国国家健康筛查计划提供的信息的影响。一般来说，我们发现单独的疾病风险信息反应有限。然而，我们发现有证据表明，在糖尿病高危阈值附近体重会减轻，在这种情况下，信息与主动提示进行二次检查以进行诊断和治疗相结合。
