Patterns of traffic offenses from adolescent licensure into early young adulthood.

PURPOSE: This article examines adolescent psychosocial and problem behavior characteristics as predictors of traffic offenses from licensure to early young adulthood. METHODS: Data for this study were from a school-based sample that was surveyed in 10th and 12th grades, and again in early young adulthood. In addition, state driver history records were obtained for each participant in the study and provided a complete traffic offense history. RESULTS: Models adjusted for driving exposure showed varying patterns of prediction for men and women across three types of ticketed moving violations (offenses): minor offenses, serious offenses, and alcohol offenses. Although which predictors were significant varied across gender and type of offense, results suggested that more positive psychosocial adjustment predicted lower numbers, greater decreases, and a lower likelihood of increases in offenses from licensure through the early 20s. CONCLUSIONS: Based on this research, implications for intervention include providing parents with the tools and knowledge needed to effectively supervise their teens' driving during the first years of licensure. Also potentially important for their broad positive effects on problem behaviors, including problem driving, are programs that strengthen adolescents' bonds to conventional social institutions and increase their attachment to the people who represent those institutions. Future research should examine the longitudinal sequencing of associations among psychosocial and problem behavior variables, including problem driving.

Childhood and adult socioeconomic conditions and 31-year mortality risk in women.

Links between low socioeconomic position and poor health are well established. Most previous research, however, has focused on middle-aged males and has relied on limited socioeconomic data, usually measured at one point over the life course. This paper examines all-cause, cardiovascular, and noncardiovascular mortality in women in relation to socioeconomic position at different stages of the life course. Information was collected in 1965, 1974, 1983, and 1994 and included recalled father's occupation and education as a measure of childhood socioeconomic position and the respondent's household income, education and occupation, and spouse's occupation from a sample of 3,087 women participating in the Alameda County Study. Cox regression models were used to estimate hazard ratios for risk of death. Lower childhood socioeconomic position was associated with an increased mortality due to cardiovascular disease (hazard ratio (HR) = 1.29, 95% confidence interval (CI): 1.09, 1.54) but was unrelated to death due to other causes (HR = 0.97, 95% CI: 0.82, 1.15). Overall mortality was higher among women reporting the lowest level of education (HR = 1.17, 95% CI: 0.99, 1.39), but education was most strongly related to noncardiovascular disease-related deaths (HR = 1.41, 95% CI: 1.10, 1.81). Low household income was also associated with higher mortality, for both cardiovascular disease-related (HR = 1.47, 95% CI: 1.14, 1.91) and noncardiovascular disease-related (HR = 1.30, 95% CI: 1.03, 1.63) deaths. Both early and later life indicators of socioeconomic position contribute to increased mortality risk among socioeconomically disadvantaged women, but these effects appear stronger for cardiovascular mortality.

Self-esteem and mortality: prospective evidence from a population-based study.

PURPOSE: Self-esteem is considered to be importantly associated with both psychosocial states such as depression as well as physical health. There are no population-based studies that examine the association between self-esteem and mortality. The objective of this study was to assess whether low self-esteem was prospectively associated with increased risk of death in a population-based sample of Finnish men. METHODS: A sample of 2682 male residents of Kuopio, Finland were interviewed and followed prospectively as part of the Kuopio Ischemic Heart Disease Risk Factor Study (KIHD). Characteristics of the KIHD sample at baseline included self-esteem, measured by the Rosenberg ten-item scale, socioeconomic factors, behavioral risk factors, other psychosocial characteristics, and prevalent diseases. Mortality was ascertained through linkage to the Finnish national death registry. We assessed the relationship between self-esteem and all-cause mortality using Cox proportional hazards models. RESULTS: Low self-esteem was associated with a two-fold [hazard ratio (HR)=2.0, 95% confidence interval (CI)=1.3-3.2] increase in age-adjusted mortality. This relationship was partially explained by behavioral and socioeconomic factors, and prevalent diseases, and fully explained by other psychosocial characteristics (hopelessness, depression, cynical hostility, and sullenness). When adjusted for hopelessness alone there was no increased risk associated with low self-esteem (HR=1.3, 95% CI=0.8-2.2). CONCLUSIONS: This study found no association between self-esteem and all-cause mortality after adjustment for other psychosocial characteristics, primarily hopelessness. Our understanding of the observed relationships between some psychosocial factors and mortality may be improved by simultaneous measurement of multiple psychosocial domains, thus diminishing the potential for residual confounding.

Relative or absolute standards for child poverty: a state-level analysis of infant and child mortality.

OBJECTIVES: The purpose of the present study was to compare the associations of state-referenced and federal poverty measures with states' infant and child mortality rates. METHODS: Compressed mortality and Current Population Survey data were used to examine relationships between mortality and (1) state-referenced poverty (percentage of children below half the state median income) and (2) percentage of children below the federal poverty line. RESULTS: State-referenced poverty was not associated with mortality among infants or children, whereas poverty as defined by national standards was strongly related to mortality. CONCLUSIONS: Infant and child mortality is more closely tied to families' capacity for meeting basic needs than to relative position within a state's economic hierarchy.
