Fig 1.
Surfing and bodyboarding deaths over time by incident type.
Mortality rates have been calculated using the Australian population (black) and using average surfing and bodyboard participants aged 16 years and older (dotted line).
Table 1.
Non-parametric analyses of observed proportions of the person and incident profiles of surfer and bodyboarder fatalities compared to expected proportions from various sources.
Further statistical details of expected models are denoted for each variable and described as table footnotes. Bold type indicates significance, deemed at p = 0.01 after Bonferroni correction.
Table 2.
Comparative chi-squared analyses of surfing and bodyboarding deaths to other in-water coastal activity deaths (swimming/wading, snorkelling, diving, and other watercraft, excluding surfing and bodyboarding).
Bold type indicates significance, deemed at p = 0.01 after Bonferroni correction. Unknown cases were excluded from analyses and are denoted with an asterisk (*).
Table 3.
Surfing and bodyboarding causes of death by age group drawn from coronal ICD-10 coding.
Sum of total numbers are greater than total number of deaths as some cases listed multiple causes of death, this is denoted with an asterisk(*).
Table 4.
Data and calculations used to explore estimated mortality rates per 100,000 resident and exposed populations and per one million hours of participation per participant.
Table 5.
Detailed comparison of age- and sex- specific mortality rates and 95% confidence intervals of SAB deaths and Australian deaths from all causes.
