A conceptual framework for reducing risky teen driving behaviors among minority youth

Teenage drivers, especially males, have higher rates of motor vehicle crashes and engage in riskier driving behavior than adults. Motor vehicle deaths disproportionately impact youth from poor and minority communities and in many communities there are higher rates of risky behaviors among minority youth. In this paper, the authors review the data on teens, risky driving behaviors, and morbidity and mortality. They identify areas in which known disparities exist, and examine strategies for changing teen driving behavior, identifying what has worked for improving the use of seat belts and for reducing other risky behaviors. A multifaceted, multilevel model based on ecological theory is proposed for understanding how teens make choices about driving behaviors, and to understand the array of factors that can influence these choices. The model is used to create recommendations for comprehensive intervention strategies that can be used in minority communities to reduce disparities in risk behaviors, injury, disability, and death.

Driver and Passenger Seatbelt Use Among U.S. High School Students

BACKGROUND In 2005, 40% of motor-vehicle occupant deaths in the group aged 16-19 years involved passengers. Although seatbelts can reduce crash mortality by 50% or more, little is known about the differences in driver-versus-passenger seatbelt use among teens. METHODS In 2007, data from the 2001 and 2003 Youth Risk Behavior Surveys were analyzed for 12,731 black, white, and Hispanic high school students aged >or=16 years reporting seatbelt use as both drivers and passengers. Seatbelt use was compared for driver- and passenger-seat positions, and stratified by age, gender, race/ethnicity, school grades, and histories of either drinking and driving or riding with a drinking driver. RESULTS Overall, 59% of students always used seatbelts when driving, but only 42% always buckled up as passengers. Across all covariate strata, passenger seatbelt use was significantly less prevalent than driver seatbelt use (p<0.001). A concordance analysis showed that only 38% of students always wore seatbelts both when driving and while riding as a passenger. Multivariate analyses indicated that, regardless of seat position, seatbelt use was lower for young men, blacks, students with poor grades, and students who reported either drinking and driving or riding with a drinking driver. CONCLUSIONS U.S. high school students aged >or=16 years are significantly less likely to wear seatbelts as passengers than as drivers. Interventions designed to promote seatbelt use among teens need to address this disparity.

Increased Black–White Disparities in Mortality After the Introduction of Lifesaving Innovations: A Possible Consequence of US Federal Laws

OBJECTIVES We explored whether the introduction of 3 lifesaving innovations introduced between 1989 and 1996 increased, decreased, or had no effect on disparities in Black-White mortality in the United States through 2006. METHODS Centers for Disease Control and Prevention data were used to assess disease-, age-, gender-, and race-specific changes in mortality after the introduction of highly active anti-retroviral therapy (HAART) for treatment of HIV, surfactants for neonatal respiratory distress syndrome, and Medicare reimbursement of mammography screening for breast cancer. RESULTS Disparities in Black-White mortality from HIV significantly increased after the introduction of HAART, surfactant therapy, and reimbursement for screening mammography. Between 1989 and 2006, these circumstances may have accounted for an estimated 22,441 potentially avoidable deaths among Blacks. CONCLUSIONS These descriptive data contribute to the formulation of the hypothesis that federal laws promote increased disparities in Black-White mortality by inadvertently favoring Whites with respect to access to lifesaving innovations. Failure of legislation to address known social factors is a plausible explanation, at least in part, for the observed findings. Further research is necessary to test this hypothesis, including analytic epidemiological studies designed a priori to do so.

Firearms, Youth Homicide, and Public Health

Homicide is seven times as common among U.S. non-Hispanic Black as among non-Hispanic White youth ages 15 to 24 years. In 83% of these youth homicides, the murder weapon is a firearm. Yet, for more than a decade, the national public health position on youth violence has been largely silent about the role of firearms, and tools used by public health professionals to reduce harm from other potential hazards have been unusable where guns are concerned. This deprives already underserved populations from the full benefits public health agencies might be able to deliver. In part, political prohibitions against research about direct measures of firearm control and the absence of valid public health surveillance are responsible. More refined epidemiologic theories as well as traditional public health methods are needed if the U.S. aims to reduce disparate Black-White youth homicide rates.

Community participation in health initiatives for marginalized populations.

Community-based participatory methods have emerged as a response to conventional approaches that have historically failed to make notable improvement in health status or reduce chronic disease among marginalized populations. The social-ecological model provides a framework to develop and implement strategies directed to affecting multiple levels (societal, community, organizational, and individual) of influence on health status. A systems approach can facilitate the identification of the complex interrelationships of factors at all levels that contribute to health disparities by making use of the unique knowledge, expertise, and resources of community partners. Community engagement in the planning, implementation, and evaluation of health initiatives builds community capacity to create sustainable changes at all levels to achieve and maintain optimal health for those who bear the greatest burden of disease.

BMI and Seatbelt Use

Objective: Seatbelt use among obese persons may be reduced because seatbelts are uncomfortable. We investigated the association between obesity and seatbelt use with data from the 2002 Behavioral Risk Factor Surveillance System Survey.

Improving seat belt use among teen drivers: findings from a service-learning approach.

BACKGROUND Low seat belt use and higher crash rates contribute to persistence of motor vehicle crashes as the leading cause of teenage death. Service-learning has been identified as an important component of public health interventions to improve health behavior. METHODOLOGY A service-learning intervention was conducted in eleven selected high schools across the United States in the 2011-2012 school year. Direct morning and afternoon observations of seat belt use were used to obtain baseline observations during the fall semester and post-intervention observations in the spring. The Mann-Whitney U test for 2 independent samples was used to evaluate if the intervention was associated with a statistically significant change in seat belt use. We identified factors associated with seat belt use post-intervention using multivariable logistic regression. RESULTS Overall seat belt use rate increased by 12.8%, from 70.4% at baseline to 83.2% post-intervention (p<0.0001). A statistically significant increase in seat belt use was noted among white, black, and Hispanic teen drivers. However, black and Hispanic drivers were still less likely to use seat belts while driving compared to white drivers. Female drivers and drivers who had passengers in their vehicle had increased odds of seat belt use. CONCLUSION A high school service-learning intervention was associated with improved seat belt use regardless of race, ethnicity, or gender, but did not eliminate disparities adversely affecting minority youth. Continuous incorporation of service-learning in high school curricula could benefit quality improvement evaluations aimed at disparities elimination and might improve the safety behavior of emerging youth cohorts.

United States Counties with Low Black Male Mortality Rates

OBJECTIVE In the United States, young and middle-aged black men have significantly higher total mortality than any other racial or ethnic group. We describe the characteristics of US counties with low non-Hispanic Black or African American male mortality (ages 25-64 years, 1999-2007). METHODS Information was accessed through public data, the US Census, the US Compressed Mortality File, and the Native American Graves Repatriation Act military database. RESULTS Of 1307 counties with black mortality rates classified as reliable by the National Center for Health Statistics (at least 20 deaths), 66 recorded lower mortality among black men than corresponding US whites. Most notable, 97% of the 66 counties were home to or adjacent a military installation versus 37% of comparable US counties (P<.001). Blacks in these counties had less poverty, higher percentages of elderly civilian veterans, and higher per capita income. Within these counties, national black:white disparities in mortality were eliminated for ischemic heart disease, accidents, diseases of the liver, chronic lower respiratory diseases, and mental disorder from psychoactive substance use. Application of age-, race-, ethnicity-, gender-, and urbanization-specific mortality rates from counties with relatively low mortality would reduce the black:white mortality rate ratio for black men aged 25 to 64 years from 1.67 to 1.20 nationally and to 1.00 in areas outside large central metropolitan areas. CONCLUSIONS These descriptive data demonstrate a small number of communities with low mortality rates among young and middle-aged black/African American men. Their characteristics may provide clinical and public health insights to reduce these higher mortality rates in the US population. Analytic epidemiologic studies are necessary to test these hypotheses.

Reducing Unintentional Injuries on the Nation's Highways: Research and Program Policy to Increase Seat Belt Use

Death, disability, and injury from motor vehicle accidents constitute a public health crisis. The goal of this paper is to describe how Meharry Medical Colleges Center for Community Based Research plans to address this problem. A model of how high-risk groups are influenced to engage in behaviors that increase risk for traffic crashes is articulated. Five strategies for reducing risk for motor vehicle morbidity and mortality are identified: 1) influencing the individual at the point of decision; 2) mobilizing communities and coalitions to support individual and systems changes; 3) modifying environmental factors to modify behaviors; 4) changing laws and public policy; and 5) working towards the elimination of underlying causes. The Center for Community Based Researchs promotion of seat belt use, based on each of these five strategies, is described. Addressing the public health crisis resulting from death and injury on the nations roads and the excess risk faced by minority groups in this country will require the coordinated efforts of many groups. This work must be driven by research, the outcome of which will be a reduction in preventable injury, disability and premature death.

Seat belt use among Hispanic ethnic subgroups of national origin

Objective: Findings from over a dozen studies of Hispanic/white disparities in seat belt use have been inconsistent, variably revealing that seat belt use prevalence among Hispanics is higher, lower, or comparable to use among non-Hispanics. In contrast to previous studies, this study investigates disparities in seat belt use by Hispanic subgroups of national origin. Methods: Data from the US Fatality Analysis Reporting System were used to compare seat belt use among 60 758 non-Hispanic whites and 6879 Hispanics (Mexican American (MA), n = 5175; Central American/South American (CASA), n = 876; Puerto Rican (PR), n = 412; Cuban (CU), n = 416) killed in crashes from 1999–2003. Logistic regression was used to adjust for age, gender, seat belt law, seat position, urban/rural region, and income. Results: Overall adjusted odds ratios for seat belt use among Hispanic subgroups, relative to non-Hispanic whites, were 1.04 (95% confidence interval (CI) 0.85 to 1.28) for CUs, 1.17 (95% CI 0.95 to 1.44) for PRs, 1.33 (95% CI 1.25 to 1.42) for MAs, and 1.66 (95% CI 1.44 to 1.91) for CASAs. Relative to their non-Hispanic white counterparts, odds ratios among MA and CASA Hispanics were highest for men, younger age groups, drivers, primary law states, rural areas, and lower income quartiles. Conclusion: Among all Hispanic subgroups, seat belt use was at least as prevalent as among non-Hispanic whites. In the CASA and MA subgroups, which have the most rapidly growing subpopulations of immigrants, seat belt use was significantly more common than among whites.
