The hidden war: Crime and the tragedy of public housing in Chicago

Focusing on three developments, this study chronicles the many failed efforts of the Chicago Housing Authority to combat crime and improve its high-rise developments. The authors reveal the dilemmas facing women and children who are often victims or witnesses of violent crime.

Duration of a Well-Child Visit: Association With Content, Family-Centeredness, and Satisfaction

BACKGROUND: Studies of pediatric primary care suggest that time is an important limitation to the delivery of recommended preventive services. Given the increasingly frenetic pace of pediatric practice, there is an increased need to monitor the length of pediatric visits and the association of visit length with content, family-centered care, and parent satisfaction with care. OBJECTIVE: To examine the length of well-child visits and the associations of visit length with content, family-centered care, and parent satisfaction among a national sample of children. METHODS: We conducted a cross-sectional telephone survey of parents of children aged 4 to 35 months from the 2000 National Survey of Early Childhood Health (n = 2068). RESULTS: One-third (33.6%) of parents reported spending ≤10 minutes with the clinician at their last well-child visit, nearly half (47.1%) spent 11 to 20 minutes, and 20.3% spent >20 minutes. Longer visits were associated with more anticipatory guidance, more psychosocial risk assessment, and higher family-centered care ratings. A visit of >20 minutes was associated with 2.4 (confidence interval [CI]: 1.5–3.7) higher odds of receiving a developmental assessment, 3.2 (CI: 1.7–6.1) higher odds of recommending the clinician, and 9.7 (CI: 3.5–26.5) higher odds of having enough time to ask questions. CONCLUSIONS: Many well-child visits are of short duration, and shorter visits are associated with reductions in content and quality of care and parent satisfaction with care. Efforts to improve preventive services will require strategies that address the time devoted to well-child care. The results of this study should be interpreted in light of changes in practice standards, reimbursement, and outcome measurement that have taken place since 2000 and the limitations of the measurement of utilization solely on the basis of parent report.

Changing Trends of Childhood Disability, 2001–2011

BACKGROUND: Over the past half century the prevalence of childhood disability increased dramatically, coupled with notable increases in the prevalence of mental health and neurodevelopmental conditions. This study provides a detailed assessment of recent trends in childhood disability in relation to health conditions and sociodemographic factors. METHODS: Secondary data analysis of National Health Interview Survey (NHIS) datasets 2001–2002, 2004–2005, 2007–2008, and 2010–2011 (N = 198 888) was conducted to calculate the prevalence, rate of change, severity, and sociodemographic disparities of parent-reported childhood disability. RESULTS: The prevalence of childhood disability has continued to increase, growing by 15.6% between 2001–2002 and 2010–2011. Nearly 6 million children were considered disabled in 2010–2011. Children living in poverty experienced the highest rates of disability, 102.6 cases per 1000 population in 2010–2011, but unexpectedly, children living in households with incomes ≥400% above the federal poverty level experienced the largest increase (28.4%) over this 10-year period. The percentage of disability cases related to any physical health condition declined 11.8% during the decade, whereas cases related to any neurodevelopmental or mental health condition increased by 20.9%. CONCLUSIONS: Over the past decade, parent-reported childhood disability steadily increased. As childhood disability due to physical conditions declined, there was a large increase in disabilities due to neurodevelopmental or mental health problems. For the first time since the NHIS began tracking childhood disability in 1957, the rise in reported prevalence is disproportionately occurring among socially advantaged families. This unexpected finding highlights the need to better understand the social, medical, and environmental factors influencing parent reports of childhood disability.

Classifying undetermined poisoning deaths

Objective: To classify poisoning deaths of undetermined intent as either suicide or unintentional and to estimate the extent of underreported poisoning suicides. Methods: Based on 2002 statewide death certificate and medical examiner data in Utah, the authors randomly selected one half of undetermined and unintentional poisoning deaths for data abstraction and included all suicides. Bivariate analyses assessed differences in demographics, death characteristics, forensic toxicology results, mental health history, and other potentially contributing factors. Classification and regression tree (CART) analysis used information from unintentional and suicide poisoning deaths to create a classification tree that was applied to undetermined poisoning deaths. Results: The authors analyzed 41 unintentional, 87 suicide, and 84 undetermined poisonings. Undetermined and unintentional decedents were similar in the presence of opiates, physical health problems, and drug abuse. Although none of the undetermined decedents left a suicide note, previous attempt or intent to commit suicide was reported for 11 (13%) of these cases. CART analysis identified suicidal behavior, drug abuse, physical health problems, depressed mood, and age as discriminating between suicide and unintentional poisoning. It is estimated that suicide rates related to poisoning are underreported by approximately 30% and overall suicide rates by 10%. Unintentional poisoning death rates were underreported by 61%. Conclusions: This study suggests that manner of death determination relies on circumstance dependent variables that may not be consistently captured by medical examiners. Underreporting of suicide rates has important implications in policy development, research funding, and evaluation of prevention programs.

Mediators of asthma outcomes

BACKGROUND Patient adherence, the level of asthma self-management skills, exposure to stress, and depression can have considerable influence on a wide range of asthma outcomes and thus are considered asthma outcome mediators. OBJECTIVE National Institutes of Health institutes and other federal agencies convened an expert group to recommend standardized measures for 7 domains of asthma clinical research outcomes measures. Although the review of mediators of these outcomes was not within the scope of any specific outcome topic, a brief summary is presented so that researchers might consider potential mediators. METHODS We prepared a summary of key mediators of asthma outcomes based on expertise and knowledge of the literature. RESULTS The rationale for including measures of adherence, self-management skills, and exposures to stress in asthma clinical research is presented, along with a brief review of instruments for collecting this information from clinical research participants. CONCLUSIONS Appropriate measurement of adherence, self-management skills, and exposures to stress will enhance characterization of study participants and provide information about the potential impact these factors can have on mediating the effects of treatment interventions.

Part-time Work Among Pediatricians Expands

OBJECTIVE: The objective of this study was to track trends in part-time employment among pediatricians from 2000 to 2006 and to examine differences within subgroups of pediatricians. METHODS: As part of the Periodic Survey of Fellows, national random samples of American Academy of Pediatrics members were surveyed in 2000, 2003, and 2006. These surveys shared questions concerning working part-time and other practice characteristics. Roughly 1600 pediatricians were included in each random sample. Totals of 812 (51%), 1020 (63%), and 1013 (62%) pediatricians completed the surveys in 2000, 2003, and 2006, respectively. Analyses were limited to nonretired, posttrainee pediatricians. RESULTS: The number of pediatricians who reported that they work part-time increased from 15% in 2000, to 20% in 2003, to 23% in 2006. The pattern of increased part-time work from 2000 to 2006 held for many subgroups, including men, women, pediatricians who were younger than 40 years, pediatricians who were aged ≥50 years, pediatricians who worked in an urban inner city, pediatricians who worked in suburban areas, general pediatricians, and subspecialist pediatricians. Those who were working part-time were more satisfied within their professional and personal activities. Part-time pediatricians worked on average 14.3 fewer hours per week in direct patient care. CONCLUSIONS: Increases in part-time work are apparent throughout pediatrics. The possible continued growth of part-time is an important trend within the field of pediatrics that will need to be monitored.

At What Age Can Children Report Dependably on Their Asthma Health Status

OBJECTIVE. This study examined psychometric properties and feasibility issues surrounding child-reported asthma health status data. METHODS. In separate interviews, parents and children completed 3 visits. Child questionnaires were interviewer administered. The primary instrument was the Childrens Health Survey for Asthma–Child Version, used to compute 3 scales (physical health, activities, and emotional health). The following were assessed: reliability (internal consistency and test-retest reliability), validity (general health status, symptom burden, and lung function), and feasibility (completion time, missing data, and inconsistent responses). RESULTS. A total of 414 parent-child pairs completed the study (mean child age: 11.5 years). Reliability estimates for the activities and emotional health scales were >.70 in all but 1 age category; 5 of 9 age groups had acceptable internal consistency ratings (≥.70) for the physical health scale. Cronbachs α tended to increase with child age. In general, test-retest correlations between forms and intraclass correlation coefficients were strong for all ages but tended to increase with child age. Correlations between forms ranged from .57 (7-year-old subjects, physical health) to .96 (14-year-old subjects, activities). Intraclass correlation coefficients ranged from .76 (13-year-old subjects, emotional health) to .94 (15–16-year-old subjects, physical health). Children with less symptom burden reported higher mean Childrens Health Survey for Asthma–Child Version scores (indicating better health status) for each scale, at significant levels for nearly all age groups. Childrens Health Survey for Asthma–Child Version completion times decreased from 12.9 minutes at age 7 to 6.9 minutes at age 13. CONCLUSIONS. This research indicates that children with asthma as young as 7 may be dependable and valuable reporters of their health. Data quality tends to improve with age.

Measuring Health Status and Quality of Life for US Children: Relationship to Race, Ethnicity, and Income Status

OBJECTIVE Accurately measuring the health of the increasingly diverse population of US children requires instruments that are comparable and valid across cultures, economic background, and language. This paper asks: Has the field of pediatric health status measures reached this level of comprehensiveness? METHODS Childrens health status and quality of life measures commonly used in the United States were reviewed to assess how they have included racial/ethnic minority and low-income groups. Four generic and 2 condition-specific instruments (asthma) were examined for total sample size, percent of sample from racial/ethnic and low-income groups, language availability, translation methods for US-Spanish, reading level, and separately reported psychometric findings and outcomes/scores. RESULTS Most measures have included minority groups, usually African American or Hispanic children, although with little information by Hispanic subgroup. Childrens measures have generally been tested on relatively small samples, without separate analyses by subgroups. When done, tests of reliability and validity find few differences from the general population. Some studies report information on health by racial or ethnic group, but the findings are inconclusive. Economic status is usually measured in some way, but rarely are psychometric findings examined separately by income. When differences in health outcome are reported by income, lower income children usually have poorer health. CONCLUSIONS Much has been accomplished in advancing health status measures for children. Next-generation issues include the influence of race, ethnicity, and income on health and health reports.

The fast and the fatal: street racing fatal crashes in the United States

The objective of this study was to determine the annual incidence of fatal motor vehicle crashes involving street racing and to describe the characteristics of these crashes compared to other fatal crashes in the United States. The National Highway Traffic Safety Administration Fatality Analysis Reporting System data for 1998–2001 were used for the analyses. There were 149 568 fatal crashes and 315 (0.21%) involved street racing and 399 fatalities occurred in these crashes. In contrast to other fatal crashes, street racing fatal crashes were more likely to occur on urban roadways and were nearly six times more likely to occur at travel speeds ≥65 mph. Compared with other drivers involved in fatal crashes, street racers were more likely to be teenagers, male, and have previous crashes and driving violations. Street racing involves risky driving behaviors and warrants further attention.

Cognitive Ability at Kindergarten Entry and Socioeconomic Status

OBJECTIVE: To examine how gradients in socioeconomic status (SES) impact US children’s reading and math ability at kindergarten entry and determine the contributions of family background, health, home learning, parenting, and early education factors to those gradients. METHODS: Analysis of 6600 children with cognitive assessments at kindergarten entry from the US Early Childhood Longitudinal Birth Cohort Study. A composite SES measure based on parent’s occupation, education, and income was divided into quintiles. Wald F tests assessed bivariate associations between SES and child’s cognitive ability and candidate explanatory variables. A decomposition methodology examined mediators of early cognitive gradients. RESULTS: Average reading percentile rankings increased from 34 to 67 across SES quintiles and math from 33 to 70. Children in lower SES quintiles had younger mothers, less frequent parent reading, less home computer use (27%–84%), and fewer books at home (26–114). Parent’s supportive interactions, expectations for their child to earn a college degree (57%–96%), and child’s preschool attendance (64%–89%) increased across quintiles. Candidate explanatory factors explained just over half the gradients, with family background factors explaining 8% to 13%, health factors 4% to 6%, home learning environment 18%, parenting style/beliefs 14% to 15%, and early education 6% to 7% of the gaps between the lowest versus highest quintiles in reading and math. CONCLUSIONS: Steep social gradients in cognitive outcomes at kindergarten are due to many factors. Findings suggest policies targeting levels of socioeconomic inequality and a range of early childhood interventions are needed to address these disparities.
