Trends and Disparities in TB among U.S.-born Black and White Chicago Residents, 1998-2008
ABSTRACT
OBJECTIVE: To describe the decline of tuberculosis (TB) cases among U.S.-born non-Hispanic (NH) black and white Chicago residents.
METHODS: Data from the National TB Surveillance System was used to analyze trends and characteristics of reported TB cases among U.S.-born NH black and U.S.-born NH white Chicago residents from 1998-2008.
RESULTS: Chicago reported a total of 3,821 TB cases over the 11-year time period. Of these, 1,916 were U.S.-born NH black and 235 were U.S.-born NH white. The proportion of cases attributable to U.S.-born NH blacks was 63% (294/469) in 1998 and 34% in 2008 (72/213). Analysis for trends from 2000-2008 revealed a greater than predicted decrease in rates among U.S.-born NH blacks (p
CONCLUSION: Despite more TB risk factors in Chicago’s U.S.-born black population, there was a narrowing of TB case disparity in Chicago from 1998-2008. Continued focused strategies aimed at controlling TB are needed
Harnessing the strength of families to prevent social problems and promote adolescent well-being
The family context exerts notable influence on many domains of adolescent development and well-being. Recent research indicates that the family has the power not only to help youth get back on course after problems emerge, but that the family can also play a critical role in preventing problems for youth by reducing the severity of a problem or mitigating its occurrence. The purpose of this paper is to outline the promise and challenges of family-based approaches to prevention in social work practice. Research and theory have identified numerous risk and protective factors in the family. Prevention programs that address these risk and protective factors have shown strong evidence of reducing youth risky behavior. Program effects vary based on the strength of program implementation. Agencies often face barriers to implementation including maintaining model fidelity, engaging families, and sustaining funding. Implications for practice and policy are discussed
Patterns of Stepfamily Relationship Quality and Adolescents' Short-Term and Long-Term Adjustment
Stepfamilies experience unique dynamics, with implications for family functioning and youth well-being. Emerging research is incorporating a holistic perspective whereby stepfamily dynamics are viewed more comprehensively, and constellations of stepfamily relationship quality are identified. In the current study, we examined short-term and long-term associations between latent patterns of stepfamily relationships (including the quality of mother–child, stepfather–child, nonresident father–child, and stepcouple dyads) and youth adjustment (i.e., depression, delinquency, self-esteem) across three stages of youth development: adolescence, emerging adulthood, and young adulthood. Using a representative sample of adolescents from the National Longitudinal Study of Adolescent to Adult Health (Harris et al., 2009), results from longitudinal structural equation models and latent-growth curve models indicated that youth adjustment over time is optimized among youth in a residence-centered (i.e., high-quality relationships among mother–child, stepfather–child, and stepcouple dyads) or inclusive (i.e., high-quality relationships across all dyads, including the nonresident father) pattern, as compared with youth in an unhappy-couple (i.e., low-quality stepcouple relationship) or parent–child disconnection (i.e., low-quality relationships between youth and each parental figure) pattern. The results point to many similarities between male and female youth in terms of adjustment responses to patterns of stepfamily relationships, although some differences became apparent. In the context of stepfamily relationships marked by low-quality relationships, male youth might exhibit greater initial levels of externalizing problems than female youth, whereas female youth might exhibit greater initial levels of internalizing problems than male youth. Implications for future research and intervention and prevention efforts are discussed
Day-to-day Consistency in Positive Parent–Child Interactions and Youth Well-Being
The frequency of positive parent–child interactions is associated with youth adjustment. Yet, little is known about daily parent–child interactions and how day-to-day consistency in positive parent–child interactions may be linked to youth well-being. Using a daily diary approach, this study added to this literature to investigate whether and how day-to-day consistency in positive parent–child interactions was linked to youth depressive symptoms, risky behavior, and physical health. Participants were youth whose parents were employed in the IT division of a Fortune 500 company (N = 129, youth’s mean age = 13.39, 55 % female), who participated in an 8 day daily diary study. Analyses revealed that, controlling for cross-day mean levels of positive parent–child interactions, older (but not younger) adolescents who experienced more consistency in positive interactions with parents had fewer depressive and physical health symptoms (e.g., colds, flu). The discussion focuses on the utility of daily diary methods for assessing the correlates of consistency in parenting, possible processes underlying these associations, and intervention implications
Daily parental knowledge of youth activities is linked to youth physical symptoms and HPA functioning.
Considerable evidence documents linkages between parental knowledge of youth activities and youth risky behavior. We extended this research to determine whether parental knowledge was associated with youth physical health, including reports of physical symptoms (e.g., headaches, stomachaches) and a biomarker of hypothalamic pituitary adrenocortical (HPA) axis functioning (i.e., salivary cortisol levels). Participants were children of employees in the Information Technology division of a Fortune 500 company (N = 132, Mean Age Youth = 13.39 years, 55% female) who participated in a daily diary study. Data were collected via telephone calls on eight consecutive evenings. On four study days, cortisol samples were collected at 4 time points (waking, 30 min after waking, before dinner, bedtime). Multi-level models revealed that, at the between-person level, youth whose parents had higher average knowledge about their activities, exhibited lower bedtime cortisol levels. Furthermore, at the within-person level, on days when parents displayed more knowledge than usual (relative to their own eight-day average), youth had lower before-dinner cortisol than usual. Linkages between average parental knowledge and physical health symptoms were moderated by youth age: Younger but not older adolescents whose parents were more knowledgeable had fewer physical health symptoms, on average. A next step is to identify the processes that underlie these associations
Stepfamily Relationship Quality and Children’s Internalizing and Externalizing Problems
The stepfamily literature is replete with between-group analyses by which youth residing in stepfamilies are compared to youth in other family structures across indicators of adjustment and well-being. Few longitudinal studies examine variation in stepfamily functioning to identify factors that promote the positive adjustment of stepchildren over time. Using a longitudinal sample of 191 stepchildren (56% female, mean age = 11.3 years), the current study examines the association between the relationship quality of three central stepfamily dyads (stepparent–child, parent–child, and stepcouple) and children's internalizing and externalizing problems concurrently and over time. Results from path analyses indicate that higher levels of parent–child affective quality are associated with lower levels of children's concurrent internalizing and externalizing problems at Wave 1. Higher levels of stepparent–child affective quality are associated with decreases in children's internalizing and externalizing problems at Wave 2 (6 months beyond baseline), even after controlling for children's internalizing and externalizing problems at Wave 1 and other covariates. The stepcouple relationship was not directly linked to youth outcomes. Our findings provide implications for future research and practice
Knowledge Lability: Within-Person Changes in Parental Knowledge and Their Associations with Adolescent Problem Behavior
Higher levels of parental knowledge about youth activities has been associated with lower levels of youth risky behavior. Yet little is known about how parental knowledge fluctuates during early adolescence and how those fluctuations are associated with the development of problem behavior. We use the term lability to describe within-person fluctuations in knowledge over time with higher lability indicating greater fluctuations in knowledge from year-to-year. This longitudinal study of rural adolescents (N = 840) investigated if change in parental knowledge across four waves of data from Grades 6 to 8 is characterized by lability, and if greater lability is associated with higher youth substance use, delinquency, and internalizing problems in Grade 9. Our models indicated that only some of the variance in parental knowledge was accounted for by developmental trends. The remaining residual variance reflects within-person fluctuations around these trends, lability, plus measurement and occasion-specific error. Even controlling for level and developmental trends in knowledge, higher knowledge lability (i.e., more fluctuation) was associated with increased risk for later alcohol and tobacco use, and for girls, higher delinquency and internalizing problems. Our findings suggest that lability in parental knowledge has unique implications for adolescent outcomes. The discussion focuses on mechanisms that may link knowledge lability to substance use. Interventions may be most effective if they teach parents to consistently and predictably decrease knowledge across early adolescence
Daily stressor reactivity during adolescence: The buffering role of parental warmth.
This study examined youth stressor reactivity in the form of links between daily stressors and adolescents’ negative affect, physical health symptoms, and cortisol patterns. We also tested whether youth gender and parental warmth moderated these linkages

Differentiating anxiety from fear: An experimental-pharmacological approach
Gray’s theory of personality postulates that fear and anxiety are distinct emotional systems with only the latter being sensitive to anxiolytic drugs. His work was mainly based on animal research and translational studies validating his theory are scarce. Previous work in humans showed an influence of the benzodiazepine lorazepam on both systems, however, dependent on dosage (1 and 2mg) and personality differences in negative emotionality. The present study aims to replicate these findings, and in addition tests the drug threshold effect by introducing a lower dosage of 0.5mg lorazepam.
Fifty healthy adults (23 males, agemean 22.40, SD±3.68) participated in an experimental threat-avoidance paradigm designed to dissociate risk assessment intensity (RAI, reflecting anxiety) and flight intensity (FI, reflecting fear) and completed two self-report questionnaires assessing facets of negative emotionality (Spielberger Trait Anxiety Inventory and Fear Survey Schedule). In a randomized placebo-controlled within-subject design, 0.5mg and 1mg of lorazepam were applied per os. Saccadic peak velocity was assessed by means of eye-tracking in order to control for sedating drug effects.
Results showed the expected and specific anxiolytic effect of lorazepam on RAI, however only in the 0.5mg condition. FI was not influenced by lorazepam and previous findings of interaction effects of lorazepam with self-reported negative emotionality could not be corroborated.
Overall, this study demonstrates anxiolytic effects of lorazepam in dosages ≤ 1mg in the absence of a drug effect on fear using a translational behavioural task. However, a putative moderating role of personality on defensive behaviour has to be clarified in future research
Experiences With Parents and Youth Physical Health Symptoms and Cortisol: A Daily Diary Investigation
Using daily diary data, this study examined the associations between positive and negative parent-youth experiences and youth cortisol and physical health symptoms among a sample of adolescents (N=132, Mean Age = 13.39). On days when girls reported more negative experiences than usual, they exhibited more physical health symptoms and flatter evening cortisol slopes than usual. Negative experiences with mothers were associated with higher dinner and bedtime youth cortisol levels (between-person). Daily positive experiences with fathers were linked with lower dinner cortisol levels. Youth with high levels of negative experiences, on average, were less sensitive to daily variation in negative experiences than youth who experienced lower parental negativity. We discuss the benefits of a daily diary approach
