The following information was supplied regarding data availability:. The raw data are provided in a Supplemental File. Undisputedly, traffic crashes constitute a public health concern whose impact and importance have been increasing during the past few decades. Specifically, road safety data have systematically shown how cyclists are highly vulnerable to suffering traffic crashes and severe injuries derived from them. Furthermore, although the empirical evidence is still very limited in this regard, in addition to other human factors involved in cycling crashes, distractions while cycling appear to be a major contributor to the road risk of cyclists.

The main objectives of this study were, first, to explore the prevalence and trends of cycling distractions within an international sample of bike users, and second, to determine the influence of such distractions on road crashes suffered by cyclists, simultaneously considering the explanatory role of risky behaviors errors and traffic violations as potentially mediating variables between cycling distractions and traffic crashes.

For this cross-sectional study, we analyzed the data obtained from 1, cyclists— The prevalence of different cycling distractions oscillated between The most common distractions were those related to the behavior of other users, physical elements of the road, weather conditions and phone calls. Age trends and differences were also found, thus establishing a positive association between age and distractibility during cycling. Furthermore, the effect of distractions on traffic crashes of cyclists was significant when tested together with age, risk perception and risky behaviors on the road.

The results of this study support the hypotheses that distractions have a major prevalence among bike users, and that they play a significant role in the prediction of the traffic crash rates of cyclists, through the mediation of risky behaviors. At the same time, traffic crashes bearing in mind their real consequences and features represent a serious public health concern WHO, ; WHO, ; Gopalakrishnan, For instance, more than 1. Nevertheless, most of the available research on traffic safety has been based on motorized vehicles and their users only, without considering the many factors affecting the road safety and the health of those users who choose emerging sustainable means of transport such as bicycles, i.

In other words, cyclists need not to get distracted while riding. Overall, road distraction —in short, a deviation of attention, which shifts from tasks critical to safe driving, riding or walking, to another marginal activity—is an increasing and deadly threat to road safety Stavrinos et al. Considering the habitual overstimulation implied by the road environment—especially for what concerns the urban context—distractions not only constitute an everlastingly latent factor for road users, but they also have a proven association with the probability of being involved in a traffic crash Oviedo-Trespalacios et al.

Considering statistics, cyclists represent around 7. In a study on North American cyclists, Wolfe et al. Another factor which is worth mentioning is that some of the many cyclist causalities even those involving injuries are usually under-reported, thus biasing the official statistics on the issue RoSPA, However, most of them have been related to the same result: traffic crashes potentially cause preventable injuries among the involved road users Kahn et al.

In the first place, cycling while being distracted by technology, especially for what concerns the use of cellphones, headphones and navigators, constitutes a relevant factor whose impact on the road safety of cyclists has been demonstrated by empirical studies such as the one performed by Ethan et al.

Decker et al. Other relevant external sources of distraction are related to the behavior of other road users, that, as in the case of distracted pedestrians or drivers, may influence the attention of cyclists during the riding task, causing potential impairments in their cycling performance and thus explaining many operational errors, subsequently deriving in potential traffic crashes.

Also, it is known that, although cyclists are highly prone to experience distractions on the road, there are some mitigating factors that differentiate them from motor vehicle drivers: bicycles are usually exempt from some typical distractors present in heavier vehicles e. Furthermore, the average low speed at which cyclists circulate, often related to the high density of traffic in urban areas, constitutes a factor which reduces the objective risk of crash and injury.

For what concerns the existing empirical studies on road distractions, most of them agree on the fact that distraction may explain a large part of traffic crashes suffered by road users, and their results have been useful for the improvement of policy and decision making regarding traffic accidents and their associated positive outcomes for traffic safety. For instance, following the results obtained by Dukic et al. Also, in Spain, billboards on the sides of inter-urban roads were prohibited in as a way of reducing the negative effects of road distractions on the performance of drivers.

Also, Stutts et al. Furthermore, road safety education of cyclists and drivers, together with a successful integration of cycling into normal traffic patterns, might help decrease the morbidity and mortality on the road Kiburz et al. To sum up, these have been our main practical motivations for developing the present study, focusing on the specific case of bicycle users.

The main purposes of this study were: first, to explore the prevalence and trends of cycling distractions in an international sample of bike users, and second, to determine their influence on road crashes involving cyclists, simultaneously considering the explanatory role of risky behaviors errors and traffic violations as potentially mediating variables between cycling distractions and traffic crashes.

The data was obtained from a full sample of 1, bike users from 20 different Latin American countries participants, representing A graphic contextualization of the geographical coverage of the project can be seen in the Fig. Differential colors indicate a greater red or lesser blue proportion of participants by country.

Regarding the educational level of participants, approximately half of the respondents A total of 9. For this research, a convenience non-probabilistic sampling method was used, grounded on the availability and accessibility to the study population, and on their willingness to participate or not in the research.

For this purpose, we designed an online electronic form in order to collect the data, and this was individually sent through an e-mail invitation to a wide sample of subjects contained in a pre-existent mailing list used for research purposes, composed of institutional members staff, students and collaborators and individuals who had previously participated in other studies. During the presentation of the survey, potential participants accessing the online form were informed about the existing laws on data protection and about the fact that the collected information would only be used for statistical and research purposes.

The questionnaire Appendix I was administrated in Spanish, and consisted of four sections: The first part asked about individual and demographic variables, such as age, gender, region of provenance, educational level and occupation. As for the second part, self-reported risky cycling behaviors were assessed using the raw item bank of the Cyclist Behavior Questionnaire CBQ Useche et al. This Likert scale is originally composed of 44 items distributed along three factors: Violations V , consisting of 16 items; Errors E , composed of 16 items; and Positive Behaviors PB , consisting of 12 items.

A global score of Risk Behaviors was built through the sum of Errors and Violations reported by respondents. Additionally, this scale includes a supplementary factor positive of protective behaviors for measuring behaviors that, unlike the first two dimensions, may help to prevent the occurrence of traffic accidents.

The last part of the questionnaire consisted of a series of questions related to the use of bikes, such as the average use of the bicycle including average distances traveled and length of trips and reasons for using it as a mode of transportation. Finally, this section of the questionnaire also included two questions about the traffic crashes suffered by participants, as cyclists: first, if they had suffered or not cycling crashes during the previous five years—regardless of their severity, but specifying that they were non-fatal crashes—and, second, in case of an affirmative answer, the number of crashes suffered during this period while cycling.

They certified that the research responded to the general ethical principles, was currently relevant for research in Social Sciences, and accorded with the Declaration of Helsinki, thus issuing a favorable opinion IRB approval number H Furthermore, an informed consent statement containing ethical principles and data treatment details was used for all participants, explaining the objectives of the study, the average duration of the survey, the treatment of personal data and the voluntary participation, and it was always provided to the participants before they answered the questionnaire.

In addition to the descriptive analyses, conducted in order to obtain the frequencies of distractions experienced by cyclists, and to the average scores for the used scales, a correlation analysis was performed to establish potential relationships among the variables of the study.

Furthermore, the association between distractions, age and risk perception, traffic crashes suffered while cycling during the previous five years, and the potential mediation of this relationship with cycling errors and normative violations, were tested using structural equation modeling SEM. The model fit was evaluated through several statistics and indices from different logics and families. Fit was decided based on the cut-off criteria expanded in the literature.

A CFI above. SEM were estimated in Mplus 8. Finally, and regardless of the severity, Table 1 summarizes the first block of descriptive statistics i. Overall, all the distractors had a relevant influence over cyclists, in a rage between Specifically, and based on the list contained in the table, the most frequently reported distracting sources which affected cyclists were the behaviors of other road users On the other hand, the least reported distracting sources were: billboards visual elements with It is worth mentioning that, although they are part of the same potentially distracting element i.

A shows the prevalence frequencies and percentages of different distractors on the road potentially affecting cyclists. B presents the number of reported distractions. Overall, the most prevalent rate by participant was to experience between four and five distractions while cycling As for the number of distracting sources reported by each participant, Table 1B shows that Also, it shows that only 1.

For what concerns the second block of descriptive analysis, a continuous variable was built i. In this regard, both cyclists who consider that they do not experience any of the distractions when using the bicycle and cyclists that report being affected by all of them were found. Furthermore, age comparisons were performed in order to determine the hypothesized differences in distractions among different age groups.

For this reason, five different age intervals were created for conducting the comparative analysis, as summarized in Table 2. The mean values on cycling distractions sum , according to the age group of cyclists, distributed in year intervals.

Comparatively the average score on cycling distractions of each age group or interval. Overall, this value seems to be increased according to the age of cyclists. Specifically, distractions were significantly related to cycling intensity i.

In A , one can see the entire set of correlations between numerical variables of the study that arose from the analysis of a full participant sample 1, individuals.

Although directions and significance levels are mostly coincidental a few differences can be observed, especially the relationship between demographic factors such as age and cycling habits.

It is interesting to note how traffic crash rates of Latin American participants show differential values of significance if compared to cyclists from Europe and North America in the case of demographic age and cycling-related factors cycling intensity.

Despite the initial disproportionality of sub-samples used for this complementary analysis, most of the significance levels and magnitudes keep similar values, as shown in Table 3B. With the aim of testing the hypothesis of the effect of cycling distractions, age and risk perception in traffic crashes involving cyclists, and the potential mediating role of errors and traffic violations within an explicative dynamic, a structural equation model SEM was built according to the empirical directions reported in the introduction.

Age, distractions built up through the sum of an eight-item scale, as shown in Fig. Therefore, several modifications were made. Firstly, two non-significant and very low paths from distractions to traffic crash rates and to violations were set to zero. Secondly, a very large modification index that pointed out a relevant relationship between the two first indicators of distractions was included. All standardized parameter estimates are presented in Fig.

The directions and significances of the variables contained in the path SEM analysis. Both cycling errors and violations mediate the predictive role of distractions on traffic crash rates. In other words, the higher the age of cyclists, the less prone to experience cycling accidents they are.

As for the second mediating variable traffic violations while cycling , this relationship follows the predictive model when considering age, i. In other words, the observed relationships between study variables suggest that both errors and violations need to be kept in mind when considering the causal chain, in order to establish a predictive link between distractions and risk perception independent variables , and the number of crashes suffered by cyclists during the last five years: a younger age and risk perception, and a higher score in cycling distractions predict more traffic crashes, through the commission of both non-deliberate errors and deliberate violations risky behaviors while riding.

Bearing in mind the first objective of the study, i. Overall, the results of this research support the existence of a relationship between cycling distractions, individual variables, road behaviors and traffic crashes experienced by bicycle users. In this regard, and although the accumulated evidence on this subject principally for what concerns the specific case of cyclists is relatively limited, some key theoretical facts may enhance the comprehension of these relationships in the light of other empirical findings gathered in groups of cyclists from different countries.

For instance, Montoro et al. Also, Wolfe et al. However, traffic policies aimed at cyclists are notably scarce and remain a pending issue in most countries Lang, ; Useche et al. Summarizing the data, our first relevant point was the fact that, as for other groups of road users, distractions affect most cyclists with different frequencies and at different degrees.

In this sense:.

So before I began buying dirt bikes for my kids, my wife, and myself, I studied out the risks. There are three problems with the risk avoidance approach; it does not teach necessary cycling skills, it does not reflect the broader cycling environment and it creates a false sense of security at the possible cost of taking time to learn good bike handling and road cycling skills.

Hand-held radar speed metres were used to read travelling speeds of E-bikes and a pro forma observation checklist was used to collect data on road riding practice. Mixed-effect logistic regressions were used to calculate adjusted ORs and 95 CIs for the association between speeding, road rule violations and helmet use and their influencing factors.

Results: Among E-bikes with a speed reading, Among a further 20 E-bikers observed, No regional variation was identified between urban and rural areas. Male E-bikers were associated with more speeding and road rule violations, whereas riding a pedal-equipped E-bike was associated with less road rule violations and less helmet use. Conclusions: Unsafe riding practices such as speeding, road rule violations and lack of helmet use were commonplace among E-bikers, especially among men.

The study findings indicate that measures aimed at improving E-bike safety are required in China. AB - Background: Electric bike E-bike -related deaths have been increasing rapidly in China and such injuries may be partly attributable to unsafe riding practice.

The Most Dangerous Things You Can Do on a Bike

Bicycling is a common form of transportation and recreation and has gained popularity among the elderly patients. In recent years, the number of elderly cyclists has increased steadily and studies have cited ease of use, need for exercise, and enjoyment as important contributing factors. The benefits of physical activity on health is well-documented, and elderly individuals are encouraged to remain active to reduce the progression of age-related weakness and loss of muscle mass.

Safety concerns, however, have been a prevalent public health issue. According to the Center for Disease Control and Prevention, elderly and teenage cyclists account for the highest number of head injuries and fatalities among all cyclists.

Safety measures that include wearing protective gear such as helmets and choosing the appropriate bicycle have been recommended to minimize the risk of sustaining injuries while riding. Despite these concerns, bicycling has remained a popular and exciting activity for the elderly patients. The population is aging, and increased susceptibility to falls is a common hallmark of aging.

However, bicycle users are also prone to cycling-related injuries that have been documented. Acute trauma may involve both upper and lower extremities, head, and thoracoabdominal injuries.

There are several contributing factors associated with increased risks involved with cycling among elderly patients. However, given the extensive scope of that endeavor, the goal of this article is to address a few of those problems. These include visual, strength, and cognition-related issues Table 1. Moreover, we will provide recommendations for cycling in addition to addressing safety factors to optimize bicycling for elders interested, or already involved in the activity.

Individuals within the geriatric community may have decreased peripheral vision, coordination, and balance, as well as reduced cognitive function and judgment. Due to the previously mentioned modifications associated with senescence, it may prove difficult for the elderly patients to simultaneously maintain balance, exert force, and display swift decision-making while bicycling.

Cycling injuries produce significant morbidity and mortality. Sparse data are available in the literature to discern specific injuries suffered by the elderly patients while cycling. Robinson et al deduced that the rate of nonunion following clavicular fractures is significantly increased with advancing age. In regard to chronic injury, common overuse injuries in cyclists result in anterior knee pain and patellofemoral pain syndrome PFPS.

For mild cases, patients make adjustments to the bicycle fit and ensure the exercise intensity and distance are appropriate. Recommending quadriceps, hamstring, and iliotibial band stretches and exercises may reduce symptoms via decreasing the stress at the patellofemoral joint.

For refractory neuropathies, operative management yields optimal results. Optimizing benefits and minimizing risks are important to enjoying cycling as an elderly individual. Safety measures of cycling must be taken at all times to reduce the incidence of sustaining debilitating injuries while cycling Table 2. However, data are scare regarding which specific type of helmet to wear for elderly patients. Although all helmets offer protection, it is our opinion that properly fitted helmet will best protect the cyclist from loose head movements that may contribute to head injuries upon impact.

Vision checks are particularly important as well, given the age-related visual decline associated with the elderly patients. In these examinations, paying attention to footwear is vital. Loose or poor-fitting footwear can be associated with increased risks of falls and sustaining injuries. Types of bicycles also play a role in safety of the cyclist. In a study done by Twisk et al, it was found that pedelecs bicycles with electric component were associated with higher injury risks than conventional bicycles.

Outdoor cycling, though enjoyable, is associated with ancillary risk factors that may pose safety hazards. The weather and road conditions pose unfavorable conditions to cycling.

For example, heavy winds, rain, snow, and nighttime riding should be avoided when cycling to reduce risk of falls and other injuries. Literature is scarce regarding specific recommendations for those who should not be allowed to cycle. However, recommendations based on results from annual physical examination should provide an adequate assessment. Furthermore, it is our opinion that elderly individuals with physical impairments, recent injuries, notable cognitive decline, or those requiring assistance with activities of daily living should not be allowed to cycle without further assessment.

Although there is a rich supply of literature explaining the risks and benefits of cycling within the general community, limited data depict the additional risk the elderly patients are subjected to during cycling. Recent strides in geriatric wellness have contributed to the stable increase in individuals living beyond the age of However, Olmedillas et al reported that biking may not be ideal for bone health as bikers have generally shown lower bone mass than nonbikers.

Overall, bicycling should be encouraged in elderly individuals under safe conditions, given the several benefits it provides. To that end, safety measures should be followed at all times while cycling to avoid potential debilitating injuries. Hershey Medical Center. National Center for Biotechnology Information , U.
