BackgroundMillions of community-dwelling individuals run marathons each year. There are infrequent deaths, which are often reported widely, and may create unnecessary alarm about the potential risks. Equally, sensible planning for such eventualities is important when staging an event.ObjectiveThe aim of the review was to determine the risk of death from running a marathon and the likely location of such deaths in order to inform the public of the likely risks and improve planning for such events.DesignNarrative review.Data sourcesPrimary: PubMed. Secondary: contact was made with the organisers and medical teams of specific marathons and online data sought where necessary.Eligibility criteria for selecting studiesStudies had to report the number of participants and deaths during, or within 24 hours of completing the marathon. Results relevant to half marathons or ultramarathons or other endurance events, such as triathlons, were not included. Deaths due to terrorist activity were not included.ResultsThe risk of death estimated by these studies was approximately 0.67 per 100 000 finishers, that is, 1 death per 149 968 participants. From those studies that reported deaths by sex, the rate of male deaths was 0.98/100 000 (1 per 102 503) vs 0.41/100 000 (1 per 243 879) in females. Deaths tended to occur in the last quarter of the race.Summary/conclusionThe risk of death from participating in a marathon is small. Men are more at risk than women. Deaths tend to occur later in the race.

The purpose of this study was to identify AIDS-related knowledge, attitudes, beliefs, and short-term behavioral intentions of adolescents attending five Seventh-day Adventist (SDA) parochial high schools in the Republic of Trinidad and Tobago. This is the first known research on AIDS to be conducted in parochial and specifically, SDA schools in the Caribbean and particularly, Trinidad and Tobago. Information gathered from this research will be useful in planning appropriate AIDS education and prevention programs for the schools represented in this survey.
