Abstract [en]

Previous studies have shown that runners differ in terms of sociodemographic characteristics. However, given the increase in participants at running races, the question arises whether these sociodemographic differences have been erased and if the second running boom has democratized running. An online questionnaire was sent to a randomized sample (n = 2378) of finishers at the 2017 Gothenburg half marathon (Göteborgsvarvet). The self-reported sociodemographic variables were then compared to Swedish national averages. The results show that Göteborgsvarvet finishers are considerably more likely to be men, well-educated and employed, compared to the general population of Sweden. This study indicates, therefore, that half marathon finishers are still distinctly different in terms of sociodemographic variables compared to the general population. These differences need to be taken into consideration when conclusions are drawn concerning running and its health effects on runners.

Abstract [en]

Background Whilst many health benefits are associated with regular exercise, medical complications may occur during higher-intensity activities, such as long distance running contests. The most common complication is collapse. However, the incidence and characteristics of these collapses are not very well studied. Method This is a retrospective study of severe collapse, defined as a patient in need of advanced medical care after a collapse, during the large Gothenburg's half marathon, Goteborgsvarvet. The study included 230,501 competitors during the study-period of 5 years (20132017) with data being collected from medical race tents and using ambulance data. Vital signs, treatment and blood gas samples were noted and analyzed. Results The incidence of severe collapse was 1.53 per 1000 starting runners. The average age for patients was 34 years old and no difference in incidence were seen between male and female runners. The typical collapsed runner presented with tachycardia, normal systolic blood pressure, elevated body temperature and metabolic acidosis. The most common medical encounter was exercise-associated collapse. Conclusion The incidence of severe collapse was similar to findings in other studies, even though this study was set in different part of the world. Typical characteristics of a collapsed runner were identified providing new information which could be beneficial in the medical planning of larger running competitions and future preventative interventions. Importantly, life threatening conditions seem uncommon; no case of hyponatremia and only two cases of hypoglycemia were seen.

Abstract [en]

The aim was to analyze the influence of weather conditions on medical emergencies in a half-marathon, specifically by evaluating its relation to the number of non-finishers, ambulance-required assistances, and collapses in need of ambulance as well as looking at the location of such emergencies on the race course. Seven years of data from the world's largest half marathon were used. Meteorological data were obtained from a nearby weather station, and the Physiological Equivalent Temperature (PET) index was used as a measure of general weather conditions. Of the 315,919 race starters, 104 runners out of the 140 ambulance-required assistances needed ambulance services due to collapses. Maximum air temperature and PET significantly co-variated with ambulance-required assistances, collapses, and non-finishers (R (2) =0.65-0.92; p=0.001-0.03). When air temperatures vary between 15-29 degrees C, an increase of 1 degrees C results in an increase of 2.5 (0.008/1000) ambulance-required assistances, 2.5 (0.008/1000) collapses (needing ambulance services), and 107 (0.34/1000) non-finishers. The results also indicate that when the daily maximum PET varies between 18-35 degrees C, an increase of 1 degrees C PET results in an increase of 1.8 collapses (0.006/1000) needing ambulance services and 66 non-finishers (0.21/1000).

Abstract [en]

Background

Fall injuries affect the lives of older people to a substantial degree. This quasi-experimental observational study investigates the potential fall injury reducing effect of a compliant flooring in a residential care setting.

Methods

The allocation of the compliant flooring was non-random. Data on fall-events and individual characteristics were collected in a residential care unit during a period of 68 months. The primary outcome was the fall injury rate per fall, and a logistic regression analysis was used to test for the effect of complaint flooring. Falls per 1000 bed days was the secondary outcome, used to measure the difference in fall risk on compliant flooring versus regular flooring.

Results

The event dataset is an unbalanced panel with repeated observations on 114 individuals, with 70% women. The mean age was 84.9 years of age, the average Body Mass Index (BMI) was 24.7, and there was a mean of 6.57 (SD: 15.28) falls per individual. The unadjusted effect estimate showed a non-significant relative risk injury reduction of 29% per fall (RR 0.71 [95% CI: 0.46–1.09]) compared to regular flooring. Re-estimating, excluding identified outliers, showed an injury risk reduction of 63% (RR 0.37 [95% CI: 0.25–0.54]). Falls per 1000 bed days showed that individuals living in apartments with compliant flooring had a fall rate of 5.3 per 1000 bed days compared to a fall rate of 8.4 per 1000 bed days among individuals living in regular apartments. This corresponds to an incidence rate ratio (IRR) of 0.63 (95% exact Poisson CI: 0.50–0.80).

Conclusion

The results of this non-randomized study indicate that compliant flooring has the potential to reduce the risk of fall injury without increasing the fall risk among older people in a Swedish residential care setting.

Abstract [en]

OBJECTIVE: To estimate the effects of fire safe cigarette laws on fire mortality and cigarette-related fires in the USA.

METHODS: We examined the gradual implementation of the laws to identify their average effects, using difference-in-differences analysis to account for common year effects, time-invariant state effects, state-specific trends and observable time-varying state-level covariates.

RESULTS: We found no statistically significant effects on all-cause fire mortality, residential fire mortality or cigarette-caused fire rates. The estimates for cigarette-caused fire deaths were significant under some specifications, but were not robust to the inclusion of state-specific trends or comparisons to effects on other cause-determined fires.

CONCLUSIONS: Given the mixed state of our results, we conclude that previous claims regarding the effects of fire safe cigarette laws may be premature.

Abstract [en]

Background During the last decade, an increasing popularity of marathons has been seen. Although running has been shown to have considerable positive health effects, the risk of sudden death, most often due to sudden cardiac arrests, is also a risk runners expose themselves to. Whilst there are some studies on the mortality amongst long-distance runners, much of the evidence is dated. Given the increased popularity in running during the 21st century as well as the improvements in medical care at marathons, more knowledge is required on the mortality risk. Materials and method Publicly available racing and news databases were used to identify the number of entrants and finishers in half to full marathons in Sweden between 2007 and 2016 and the number of deaths that occurred in conjunction with the races. Results A total of 1,156,271 runners entered a long distance (21-42km) running race in Sweden between 2007 and 2016, and 834,412 runners finished the races (72.2%). A large majority of the finishers (677,050 (81%)) competed in distances under a full marathon. Two deaths occurred during the time period, meaning that the death rate was 0.24 (95% confidence interval 0.04–0.79) per 100,000 finishers. Conclusions This study can show that death rates in long distance running races between 2007 and 2016 in Sweden are very low, compared to previous studies. When added to the existing literature, the combined picture suggests a general downward trend in the risk of death during marathons since the 1980s.
