Health characteristics, knowledge, and attitude towards basic life support among marathon runners in Thailand: a population-based survey.

Abstract

Out-of-hospital cardiac arrest (OHCA) is not common but associated with a low survival rate. There is no evidence investigating the effects of previous Basic Life Support (BLS) training among long-distance runners. The goal of this study is to demonstrate the health characteristics, knowledge, and attitudes towards BLS among marathon runners. An online cross-sectional survey was asked to all 2019 Chiang Mai University marathon participants as a part of the running registration. Details of health characteristic, running history, and BLS training details were requested. The primary outcomes were knowledge and attitude towards BLS among marathon runners. Of all 10,507 questionnaires sent, the response rate was 92.9%. One-nineth of participants were 50 years of age or above. The mean age was 36.8±9.9 years. Most were male (56.1%) and Thai (99.4%). Only a quarter (2454 out of 9761 runners) of study population had previous BLS training. Family history of sudden cardiac death or cardiac death with unknown causes was more in participants with previous BLS training than those without (1.1% vs. 0.6%, P=0.01). Previous BLS training group answered the national emergency call number correctly more than those without (90.4% vs. 73.0%, P<0.001) and previous BLS training group were more likely to initiate CPR than those without (median self-confidence 8 vs. 5, respectively, P<0.001). Only a quarter of running participants have participated in BLS training before entering a marathon running. Having previous BLS training is associated with higher self-confidence to attempt CPR. Organized planning including trained medical staff, adequate equipment, and qualified bystanders is recommended.
