Prevalence of Heat-Related Illnesses from Occupational Heat Exposure Among Motorcycle Riders in Bangkok

Abstract

This study aims to examine the prevalence of heat-related illnesses among motorcycle riders in Bangkok using a cross-sectional study design. Data were collected from 417 riders who primarily work outdoors and
are exposed to high temperatures. The study employed a questionnaire to assess individual factors, health status, behaviors, Work, environmental conditions, and symptoms of illness.

The results indicate that the majority of participants were male 94%, aged 45 - 59 years 43.6%. Most worked as full-time motorcycle riders 96.2%, worked more than eight hours per day 94.0%, and primarily worked outdoors 71.2%. The heat index in Phaya Thai District reached a maximum of 56.4°C. Regarding heat-related symptoms, on the day of the study, the most commonly reported conditions included confusion or difficulty speaking, shortness of breath, and rapid heartbeat 17.3%. Within the past month, the most prevalent symptom was headache 38.8%, while within the past year, headache remained the most frequently reported condition 37.9%.

The findings of this study provide valuable insights for developing effective strategies to mitigate heat-related health risks among motorcycle riders. This includes implementing preventive measures, particularly in urban areas where accumulated heat from road surfaces and buildings exacerbates temperature conditions. Moreover, the study highlights the need to raise awareness about appropriate health management practices during extreme heat conditions.
