Use Patterns

Objective. To describe and evaluate the helmet use patterns of children younger than 15 years of age in the United States. Methods. A national telephone survey of bicycle riders was conducted by means of the Mitofsky-Waksberg method of random-digit dialing, a survey method intended to give all telephone numbers in the continental United States an equal probability of selection. Based on information collected in the survey, a logistic regression model was used to determine and quantify the factors associated with helmet use. Results. Information was collected on the bicycle and helmet use patterns of a national sample of 399 children younger than 15 years of age who rode bicycles during the year preceding the survey. This sample projects to the approximately 26.4 million children who are estimated to have ridden bicycles in 1991. About 26% of all child riders owned or had the use of bicycle helmets, and about 15% were reported to have used their helmets all or more than half of the time when riding. Information is provided on the reasons the children did or did not wear helmets. The logistic regression analysis shows that helmet use by children is systematically related to their personal characteristics (eg, age and whether they had previously had bicycle-related accidents requiring medical attention), riding patterns (eg, riding surface), and household demographic characteristics (eg, geographic location and whether household members had attended college). Conclusions. Helmet use rates among children remain low. Less than one fifth of the children who rode bicycles wore helmets all or more than half of the time in 1991. However, based on comparisons with earlier studies, the results of the analysis suggest that helmet use rates have been rising.

The Relationship

In the United States, employment rates among individuals with disabilities are persistently low but vary substantially. In this study, we examined the relationship between employment outcomes and features of the state and county physical, economic, and policy environment among a national sample of individuals with disabilities. To do so, we merged a set of state- and county-level environmental variables with data from the 2009–2011 American Community Survey accessed in a U.S. Census Research Data Center. We estimated regression models of employment, work hours, and earnings as a function of disability, personal characteristics, and these environmental features. We found that economic conditions and physical environmental variables had stronger associations than policy variables with employment outcomes. Although the estimated importance of environmental variables was small relative to individual disability and personal characteristics, our results suggest that these variables may present barriers or facilitators to employment that can explain some geographic variation in employment outcomes across the United States.

This study tests a hypothesis that Mexican foreign-born immigrants who came to the United States for economic reasons naturalize less often than Cubans who immigrate for political reasons. It uses information from the Panel Study of Income Dynamics, Latino Sample, a national sample of 7,453 respondents from the 1989 Latino National Political Survey (LNPS) and the 1990 Panel Study of Income Dynamics (PSID). Ordinal logistic regression is used to examine the hypothesis. The results indicate that while more Mexicans plan to apply or have applied for naturalization, proportionately more Cubans than Mexicans have naturalized. Cuban political immigrants who came to the United States during the first half of the 1960s naturalize more often than their Mexican counterparts. However, the effect of ethnic identity on naturalization is mediated by a number of other predictors of naturalization such as gender, race, urban residence, socioeconomic status and acculturation.

Service Attendance

Previous research has shown that Christian nationalism is linked to nativism and immigrant animus, while religious service attendance is associated with pro-immigrant views. The findings highlight the importance of distinguishing between religious ideologies and practices when considering how religion affects politics. Using a national sample of U.S. adults, we analyze immigrant views by measuring levels of agreement or disagreement that undocumented immigrants from Mexico are “mostly dangerous criminals.” We find that Christian nationalism is inversely related to pro-immigrant views for both the religiously active and inactive. However, strongly pro-immigrant views are less likely and anti-immigrant views are more likely among strong Christian nationalists who are religiously inactive compared with strong Christian nationalists who are religiously active. These results illustrate how religious nationalism can weaken tolerance and heighten intolerance most noticeably when untethered from religious communities.

Unexpected Infant Death

AbstractThe effect of altitude on the risk of sudden infant death syndrome (SIDS) has been reported previously, but with conflicting findings. We aimed to examine whether the risk of sudden unexpected infant death (SUID) varies with altitude in the United States. Data from the Centers for Disease Control and Prevention (CDC)’s Cohort Linked Birth/Infant Death Data Set for births between 2005 and 2010 were examined. County of birth was used to estimate altitude. Logistic regression and Generalized Additive Model (GAM) were used, adjusting for year, mother’s race, Hispanic origin, marital status, age, education and smoking, father’s age and race, number of prenatal visits, plurality, live birth order, and infant’s sex, birthweight and gestation. There were 25,305,778 live births over the 6-year study period. The total number of deaths from SUID in this period were 23,673 (rate = 0.94/1000 live births). In the logistic regression model there was a small, but statistically significant, increased risk of SUID associated with birth at > 8000 feet compared with < 6000 feet (aOR = 1.93; 95% CI 1.00–3.71). The GAM showed a similar increased risk over 8000 feet, but this was not statistically significant. Only 9245 (0.037%) of mothers gave birth at > 8000 feet during the study period and 10 deaths (0.042%) were attributed to SUID. The number of SUID deaths at this altitude in the United States is very small (10 deaths in 6 years).

IN ALL COUNTRIES for which there are vital statistics, accidents are a major cause of death and disability among children. In countries where the food supply is adequate and infectious diseases have been brought under control, accidents have become the leading cause of death in the age group 1 to 19 years. For example, in such countries as Australia, Canada, Sweden, West Germany, and the United States, more than one-third of all deaths in this age group are caused by accidents. The number of children who are injured by accidents fan exceeds the number who are killed. Although no accurate international figures are available, the Morbidity Survey conducted by the United States Public Health Service indicates that in the United States, for every child under 15 killed by accident, 1,100 children are injured severely enough to require medical attention or to be restricted in their activity for at least a day.
