Household youth on minority operated farms in the United States, 2000: exposures to and injuries from work, horses, ATVs and tractors

INTRODUCTION: It is likely that youth living on minority operated farms (<3% of U.S. farms) face hazards similar to the general farm population; however, since minority youth are not well represented by general farm surveys, this information hasn't been confirmed. METHOD: Nonfatal injury and exposure data were obtained from the 2000 Minority Farm Operator Childhood Agricultural Injury Survey (M-CAIS). RESULTS: On racial minority farms, there were an estimated 28,600 household youth. Of these, about 41% worked, 26% rode a horse, 23% drove an ATV, and 23% operated a tractor. On Hispanic farms, there were an estimated 17,998 household youth. Of these, 44% worked, 30% rode a horse, 27% drove an ATV, and 25% operated a tractor. CONCLUSIONS: These results show the value of conducting a survey of minorities to identify high risk groups and target issues that may be unique to the minority farm population.     

Marketing and alcohol-related traffic fatalities: Impact of alcohol advertising targeting minors

Problem

Alcohol-related youth traffic fatalities continue as a major public-health concern. While state and federal laws can be useful in tackling this problem, the efficacy of many laws has not been empirically demonstrated. We examined the impact of state laws prohibiting alcohol advertising to target minors. Method: Using statistics obtained from the Fatality Analysis Reporting System (FARS), youth alcohol-related, single-vehicle, driver traffic fatalities were compared by state as a function of whether the state has a law prohibiting alcohol advertising that targets minors. Results: Overall, states possessing this law experienced 32.9% fewer of the above specified traffic fatalities. Discussion and Impact on Industry: The results suggest that not only are youth drinking rates affected by alcohol advertisements targeting youth, but also drink-driving behaviors. Indeed, we estimate that if this type of legislation were adopted in the 26 states that do not prohibit targeting of minors with alcohol advertising, then 400 youth lives could be saved annually.     

Children's behavioral traits and risk of injury: Analyses from a case-control study of agricultural households

Problem

Children on family agricultural operations have high risk of injury. The association between children's behavioral traits and their risk of injury is not well understood.

Method

Data from the Regional Rural Injury Study-II were used to assess behavioral risk factors for injury to children ages six to < 20 years. A total of 379 injury events (cases) and 1,562 randomly selected controls were identified. Adjusted odds ratios (OR) and 95% confidence intervals (CI), calculated using logistic regression, were used to estimate injury risk in reference to behavioral traits.

Results

Injury risks were greater for children with high levels of depressive symptoms (OR = 1.9, CI = 1.0-3.7) and aggression (OR = 1.6, CI = 0.9-2.7), and low levels of careful/cautious behavior (OR = 1.8, CI = 1.1-2.9). Children with low levels of self-regulation had reduced risks (OR = 0.4, CI = 0.2-0.8).

Discussion

Results suggest that children's behaviors affect their risk of agricultural injury. Additional research could elucidate mechanisms and inform interventions.

Impact on industry

The development of multifaceted, sustainable approaches for prevention is necessary for this unique population. These findings suggest a need for interventions that incorporate specific behavior-related risk factors in the context of family farms and ranches.     

Persistence of Violation and Crash Behavior Over Time

This analysis examines the ability of previous offenses to predict future high-risk offenses, and similarly, the ability of crashes to predict future high-risk crashes, using the complete driver history data (up to 9 years) for a set of young Michigan subjects. As expected, those with previous ticketed offenses or reported crashes are at greater risk for future offenses or crashes; with a previous-year serious offense doubling the odds of serious offenses during the subsequent year, and a previous-year at-fault crash increasing the odds of subsequent-year at-fault crashes by nearly 50%. There is modest evidence that serious offenses and at-fault crashes may better predict subsequent behavior in females and in more experienced drivers. This latter finding is also evidenced by the fact that records of these young drivers are less predictive of subsequent driving history than is true for records of all drivers in general found in other studies. This suggests that, in the early stages of driving, offenses and crashes are, at least in part, attributable to inexperience, and hence, characteristic of all beginning drivers.     

Sport participation and injury rates in high school students: A Canadian survey of 2029 adolescents

Introduction: The objective of this study is to examine sport and recreational (S&R) activity participation and injury rates (IR) in high school students (ages 14–19). Methods: High school students (N = 24 schools, n = 2,029; 958 male, 1,048 female, 23 identified ‘other’ or missing; ages 14–19) in Alberta completed a web-based survey during class (October 2018–March 2019). Students identified their top three sports for participation in the past year. Primary outcome measures included IR for (a) any S&R-related injury, (b) most serious S&R-related injury resulting in medical attention, and (c) most serious injury resulting in restriction from S&R for at least one day. Results: In total, 1763/2029 (86.89%) respondents [861/958 (89.87%) male, 886/1048 (84.54%) female, 16/23 (69.57%) identifying as ‘other’ or missing] participated in an S&R activity in the past year. Top sports for male participation were basketball (33.08%; 95% CI 27.67–39.00), ice hockey (20.46%; 95% CI 14.87–27.47), and soccer (19.42%; 95% CI 15.67–23.80). Top sports for female participation were dance (22.52%; 95% CI 17.98–27.82), basketball (18.32%; 95% CI 14.32–23.14), and badminton (17.84%; 95% CI 13.35–23.43). Of the 1,971 students completing the S&R injury question, 889 reported at least one injury during the past year [(IR = 45.10 injuries/100 students/year (95% CI 39.72–50.61)]. The medical attention IR was 29.09 injuries/100 students/year (95% CI 24.49–34.17) and time loss IR was 36.00 injuries/100 students/year (95% CI 30.47–41.93). Conclusions: High school student S&R IRs are high with 29% of adolescents reporting at least one medical attention injury within the past year. Injury prevention strategies targeting youth are necessary. Practical Application: Participation in S&R activities has multiple physical, psychological, and health benefits for adolescents, but some S&R activities also have greater risks of injury. This study informs the next sports to target for implementation of optimal prospective surveillance and injury prevention strategies among high school aged students.     

Antecedents of injury among youth in agricultural settings: a longitudinal examination of safety consciousness,dangerous risk taking,and safety knowledge

PROBLEM: Injuries are the leading cause of death for adolescents in the United States. METHODS: This study longitudinally examined three psychological mediators of injury among 3,081 youths in agricultural settings: (a) safety consciousness, (b) dangerous risk taking, and (c) safety knowledge. These variables are examined within a nomological network of contextual variables. RESULTS: Cross-sectional results revealed that safety consciousness and dangerous risk taking were the strongest predictors of reported injury at Time 1 and Time 2. Safety knowledge had an unexpected negative association with injury, albeit weak. As predicted, participating in safety activities was positively associated with safety consciousness, and time spent working was strongly associated with safety knowledge. Furthermore, self-esteem had both positive and negative safety outcomes, suggesting a more complex functioning. Males exhibited fewer safety cognitions than females as predicted. Longitudinal data also revealed that injury at Time 1 and dangerous risk taking were the strongest predictors of Time 2 injury. IMPACT ON INDUSTRY: Results from this study emphasize the importance of assessing dangerous risk-taking perceptions when attempting to predict future injuries.     

Assessment of HEADS UP online training as an educational intervention for sports officials/athletic trainers

Background: Sports- and recreation-related concussions are a common injury among children. Sports officials (SOs) and athletic trainers (ATs) are integral to setting the stage for safe play and managing concussions when they occur, and significant numbers of both groups have completed the Centers for Disease Control and Prevention’s HEADS UP online concussion training course. However, the utility of the course for these audiences has not been assessed. We hypothesized that sports officials’ and athletic trainers’ concussion-related knowledge, attitudes, and behavioral intentions will improve from pre- and post-test after completing CDC’s HEADS UP online concussion training course. Method: Respondents’ concussion-related knowledge, attitudes, and behavioral intentions were assessed both before and after taking the training course. Differences between pre- and post-test scores were calculated based on the Wilcoxon Signed Rank Test Z-score or McNemar’s test. Effect sizes were interpreted. Results: The SOs and ATs who participated in the HEADS UP online training had a high level of concussion knowledge before taking the course: 90% or more of respondents could identify the correct response for at least seven of the 13 knowledge questions in the pre-test. Still, the course was effective at improving the respondents’ knowledge about return-to-play protocols and concussion reporting. Further, SOs and ATs demonstrated improvement in their concussion-related attitudes and behavioral intentions between the pre- and post-test. Conclusion: SOs’ and ATs’ concussion knowledge, attitudes, and behavioral intentions improved immediately following completion of the CDC HEADS UP online training. Future research could also focus on the long-term retention of this type of training. Practical Applications: This study provides insight into how to better focus concussion-related educational programs to fit SOs’ and ATs’ needs.     

Soccer,concussions, and safety: Perceptions of parents of youth soccer participants

Introduction: The rate of concussions in youth soccer is among the highest of all youth sports. Parents play an important role in caring for their children and making decisions regarding whether they should participate in a sport, such as soccer, where concussions are well known. This study examined parental perceptions regarding: (a) coaches’ role in concussion management, (b) heading restriction policies, and (c) overall concussion risk and participation issues. Method: Online surveys were completed by 419 parents of youth soccer players who participated in the largest U.S. youth soccer programs nationwide. Results: Findings indicated 44.5% of the respondents had considered keeping their children from playing organized soccer and 47.2% were concerned about a potential decline in youth soccer participation due to concussions. Nearly 69% of responding parents agreed that heading should be banned for participants 10 years old or younger, while 56.5% thought heading should not be limited for participants 13 or older. Only 35% of parents were very confident about their child’s coach’s ability to properly identify concussions and remove those suspected of a concussion from play. Parents’ socioeconomic status (SES), soccer coaching and playing experience, and previous history of concussion(s) were key predictors of greater perceived risk about concussions. Conclusions: Findings from this study shed light on parents’ perceptions about concussions and related safety issues in youth soccer. Understanding what parents believe about concussions is vital to preserve youth soccer participation and can be used to strengthen education and policies that promote a safer environment for youth sport participants. Practical Applications: Youth soccer coaches can benefit from stronger, comprehensive educational efforts at the league/club level. Additionally, parents of youth athletes who are in the lower SES communities should be targeted to receive concussion safety information and/or interventions that would improve their knowledge, attitude, and practices regarding concussion safety.     

Predicting Offenses and Crashes from Young Drivers' Offense and Crash Histories

Previous research has indicated that offenses are better predictors of subsequent crashes than crashes themselves. We examined this hypothesis for 13,800 young beginning drivers in Michigan for up to nine years during the initial years of driving. Our analyses indicated that previous-year offenses are better predictors of both subsequent-year offenses and crashes than either previous-year crashes or at-fault crashes. This finding also held for the apparently higher-risk subset of subsequent-year serious offenses and at-fault crashes. Although there were no gender differences in the predictive power of crashes, it was found that the predictive power of previous offenses to subsequent serious offenses was significantly stronger for women than for men. The predictive power of incidents appeared to increase somewhat with increasing driving experience, suggesting that early incidents may be more attributable to inexperience, a characteristic of all beginning drivers, while later incidents may be more attributable to individual differences.

Adolescent noncompliance with age-specific versus universal US motorcycle helmet laws: Systematic review and meta-analysis

Introduction: The U.S. experience with motorcycle helmets affords an important insight into the responses of adolescents to age-specific laws. Political contention has led to a number of U.S. state law changes back and forth between universal and age-specific laws. Because both kinds of law require adolescent motorcyclists to wear helmets, relatively few studies have focused on how the law type affects their behavior. Method: Differential behavior is tested by a systematic review of literature, leading to a meta-analysis, in relation to the experience of various states’ motorcycle helmet laws. An electronic search was conducted for before-and-after studies in U.S. states that include data on adolescent helmet usage – both with a universally applicable motorcycle helmet law, and with an age-restricted law (usually, under-21 or under-18) – from observational, injury or fatality records for a certain period (e.g., 12 months) pre and post the state law change. Results: The search yielded ten studies, including two that compared a set of age-specific law states with a set of universal law states over the same time period. Heterogeneity analysis of seven single-state studies with raw data revealed an acceptable fit for a random-effects model. Additional noncompliance with age-restricted laws was indicated by an attributable percentage among exposed of over 65% and odds ratio exceeding 4. Conclusions: About two-thirds of adolescent noncompliance with age-restricted motorcycle helmet usage laws disappears with universal applicability. Evidence from numerous international studies of youth reaction to helmet laws suggests that a large part of the greater compliance with universal laws is due to their conveying a more convincing message that helmets afford protection against injury. Practical Applications: The meta-analysis provides fresh, young-rider perspective on the continuing debate over motorcycle-helmet laws. Broader insight into adolescent psychology suggests considering alternatives to age-restricted laws more widely in safety and health policy.     

The prediction of safe lifting behavior: an application of the theory of planned behavior

PROBLEM: Injuries resulting from lifting are costly, and create significant pain and discomfort. While engineering controls are the most effective means of reducing risks, most organizations continue to rely on manual lifting techniques. The problem, however, is that the use of safe-lifting techniques is inconsistent and managers have a difficult time motivating use of these techniques. Consequently, it is important to understand the factors driving safe-lifting behaviors. METHODS: This study used a survey to apply the theory of planned behavior (Ajzen., I., 1991. The theory of planned behavior. Organization Behavior and Human Processes, 50, 179-211) to safe-lifting among 136 materials management employees at a heavy manufacturing organization. Structural equation modeling and factor analysis were employed to analyze relationships among constructs. RESULTS: Results revealed that perceived behavioral control and intention were the strongest predictors of safe-lifting behavior. Subjective norms, to a lesser degree, were also important influences on intention. Attitudes did not surface as effective direct predictors of safe-lifting behavior, but did affect behavior and intent via mediating factors (subjective norms and perceived behavioral control). Finally, the theory of planned behavior was supported as an effective model explaining safe-lifting behavior, and had potential application for many other safety-related behaviors. IMPACT ON INDUSTRY: Results from this study emphasize the importance of perceived behavioral control as a factor associated with safety-related behavior.

12-Year longitudinal study linking within-person changes in work and family transitions and workplace injury risk

Introduction: Despite the rich tradition of research on predictors of workplace injury, most studies rely on cross-sectional, between-person designs. Furthermore, prior research has often overlooked the possibility that factors outside the work domain can influence the occurrence of actual injuries at work. To address these limitations, the current study examined the effects of work and family demands on the occurrence of workplace injury. Drawing on the intuition of the work-home resources model (W-HR), we investigated how within-person level changes in demands and resources from both domains influence work injuries over a 12-year period. Method: We used 12 years of longitudinal data (N = 7,820) to study the long-term within-person changes in work and family domains and to capture the event of low frequency incidence such as workplace injury. Specifically, we conducted multilevel analyses to study the links between within-person change in time and energy resources both in work and family domains and within-person change in the likelihood of experiencing a workplace injury. Results and conclusion: The findings showed that within-person changes in work hours, spousal work hours, income and number of children, were significantly associated with changes in the likelihood of experiencing a workplace injury. We conclude with a discussion of implications for theory and future research of workplace injuries. Practical application: The research provided useful insights on the intimate association between work and family domains in the context of safety management.     

The sound of cooperation: Musical influences on cooperative behavior

Music as an environmental aspect of professional workplaces has been closely studied with respect to consumer behavior while sparse attention has been given to its relevance for employee behavior. In this article, we focus on the influence of music upon cooperative behavior within decision‐making groups. Based on results from two extended 20‐round public goods experiments, we find that happy music significantly and positively influences cooperative behavior. We also find a significant positive association between mood and cooperative behavior. Consequently, while our studies provide partial support for the relevance of affect in relation to cooperation within groups, we also show an independently important function of happy music that fits with a theory of synchronous and rhythmic activity as a social lubricant. More generally, our findings indicate that music and perhaps other atmospheric variables that are designed to prime consumer behavior might have comparably important effects for employees and consequently warrant closer investigation.
