Trends in Fatalities From Distracted Driving in the United States, 1999 to 2008

OBJECTIVES We examined trends in distracted driving fatalities and their relation to cell phone use and texting volume. METHODS The Fatality Analysis Reporting System (FARS) records data on all road fatalities that occurred on public roads in the United States from 1999 to 2008. We studied trends in distracted driving fatalities, driver and crash characteristics, and trends in cell phone use and texting volume. We used multivariate regression analysis to estimate the relation between state-level distracted driving fatalities and texting volumes. RESULTS After declining from 1999 to 2005, fatalities from distracted driving increased 28% after 2005, rising from 4572 fatalities to 5870 in 2008. Crashes increasingly involved male drivers driving alone in collisions with roadside obstructions in urban areas. By use of multivariate analyses, we predicted that increasing texting volumes resulted in more than 16,000 additional road fatalities from 2001 to 2007. CONCLUSIONS Distracted driving is a growing public safety hazard. Specifically, the dramatic rise in texting volume since 2005 appeared to be contributing to an alarming rise in distracted driving fatalities. Legislation enacting texting bans should be paired with effective enforcement to deter drivers from using cell phones while driving.

Trends In Health Care Spending For Immigrants In The United States

The suspected burden that undocumented immigrants may place on the U.S. health care system has been a flashpoint in health care and immigration reform debates. An examination of health care spending during 1999-2006 for adult naturalized citizens and immigrant noncitizens (which includes some undocumented immigrants) finds that the cost of providing health care to immigrants is lower than that of providing care to U.S. natives and that immigrants are not contributing disproportionately to high health care costs in public programs such as Medicaid. However, noncitizen immigrants were found to be more likely than U.S. natives to have a health care visit classified as uncompensated care.

Gasoline Prices and Their Relationship to Rising Motorcycle Fatalities, 1990-2007

Motor vehicle accidents are the leading cause of death among young adults. Although automobile fatalities have declined in recent years, motorcycle fatalities are rapidly increasing. The purpose of our research was to quantify the relationship between changing fuel prices and motorcycle fatalities. Our findings suggest that people increasingly rely on motorcycles to reduce their fuel costs in response to rising gasoline prices. We estimate that use of motorcycles and scooters instead of 4-wheeled vehicles results in over 1500 additional motorcycle fatalities annually for each dollar increase in gas prices. Motorcycle safety should receive more attention as a leading public health issue.

Quality of diabetes care for immigrants in the U.S.

OBJECTIVE To compare achievement of the American Diabetes Association diabetes care recommendations for U.S.- and foreign-born individuals with diabetes. RESEARCH DESIGN AND METHODS Using the 2001–2006 Medical Expenditure Panel Surveys, we report estimates for receipt of a cholesterol test, routine checkup, influenza vaccination, eye examination, dental checkup, foot examination, and two or more A1C tests in 1 year for foreign- (n = 1,272) and U.S.-born (n = 5,811) individuals aged ≥18 years. We define a dichotomous variable representing full compliance with the above examinations. We provide descriptive characteristics of the sample and use multivariable analysis for each procedure with random effects logit regression. RESULTS Compared with U.S.-born individuals with diabetes, foreign-born individuals are younger, have lower education levels and income, are more likely to have public or no insurance, and are less likely to have a usual source of care. With adjustment for all potential confounders, foreign-born individuals are less likely to report having had an influenza vaccination (odds ratio 0.51 [95% CI 0.31–0.71]) or to be compliant with any one of the seven recommendations (0.64 [0.34–0.95]). CONCLUSIONS These findings demonstrate that immigrants are less likely than U.S.-born individuals with diabetes to adhere to any one of seven diabetes care recommendations in general and, specifically, are less likely to report having received an influenza vaccination. Because immigrants are less likely to use health care, clinicians should take advantage of the office visit to effectively communicate to the patient the importance of receiving an influenza vaccination.

Influence of number of children on cancer screening among adults in the United States

Objective To investigate the influence of children in the household on the likelihood of reporting cancer screening among adult men and women living in the United States. Methods 2004–2006 Medical Expenditure Panel Surveys (MEPS) were used to calculate the probability of self-reported cancer screening by number of children for adult men and women with adjustment for age, sex, marital status, race, education, current smoking status, obesity status, health insurance and having a usual health-care provider. Results The largest percentage of persons who had cancer screening was among respondents with no children in the household. In multivariate results, the probability of endoscopy was lower for persons with one child (24%) and two or more children (21%) in comparison with persons with no children living in the household (30%). Prostate-specific antigen (PSA) testing was lower among men with one child (17%) and two or more children (14%) in comparison with no children (22%). Pap smears were lower for women with two or more children (50%) but not different for women with one child (55%) in comparison with no children (56%). Mammograms were lower for women with one child (48%) and two or more children (42%) in comparison with no children in the household (55%). Conclusion Across several different cancer screening modalities, the probability of screening is lower as the number of children in the household increases. Children may be an additional barrier to screening beyond factors such as socioeconomic status and access to care.
