Kang T, Hong J, Radnaabaatar M, et al. - Researchers undertook this nationwide population-based ecological study to ascertain if and how meteorological factors and air pollutants (MFAPs) were related to fracture as well as to estimate the effect size/time lag. In the Korea National Health Insurance database, there were 8,093,820 patients with fractures, of those, 2,129,955 were analyzed after the data set comprising patient data (age, gender and site of fractures) were combined with MFAPs. This study sample consisted of 370,344, 187,370, 173,100, 140,358, 246,775, 6501, 228 346, 57,183 and 719,978 patients with hip, knee, shoulder, elbow, wrist, hand, ankle, foot and spine fractures, respectively. Findings revealed that fracture occurrence could be impacted by several MFAPs. Factors that were identified to be most closely associated with fracture included average temperature, daily rain, wind speed, daily snow and PM _2.5 (atmospheric particulate matter ≤2.5 µm in diameter). Therefore, there is a need for improved public awareness on these MFAPs in order to clinically prevent and manage fractures.
