Objective: Relatively little is known about the intergenerational mechanisms that lead to social disparities in child health. We examined whether the association between low socioeconomic status (SES) and child behavior problems is mediated by maternal health conditions and behavior.

Methods: Prospective cohort data (1979-1998) on 2,677 children and their mothers were obtained from the National Longitudinal Survey of Youth. SES, the Child Behavior Problems Index (BPI), and maternal smoking, depressive symptoms, and alcohol use before, during, and after pregnancy were examined.

Results: Lower income and lower maternal education were associated with increased child BPI scores. Adjustment for maternal smoking, depressive symptoms, and alcohol use attenuated the associations between SES and child BPI by 26% to 49%. These maternal health conditions often occurred together, persisted over time, and were associated with the mother's own childhood SES and pre-pregnancy health.

Conclusions: Social disparities in women's health conditions may help shape the

likelihood of behavior problems in the subsequent generation. Improved public

health programs and services for disadvantaged women across the lifecourse may

not only address their own urgent health needs, but reduce social disparities in the health and well-being of their children.

Background: The reported accuracy of transbronchial needle aspiration (TBNA) for mediastinal staging in non- small cell lung cancer (NSCLC) varies widely. We performed a meta-analysis to estimate the accuracy of TBNA for mediastinal staging in NSCLC.

Methods: We searched Medline, Embase and the bibliographies of retrieved articles, with no language restriction, for studies evaluating TBNA accuracy. We used meta-analytic methods to construct summary receiver- operating characteristic curves and to pool sensitivity and specificity.

Results: Thirteen studies met inclusion criteria, including six studies that surgically confirmed all TBNA results and enrolled at least 10 patients with and without mediastinal metastasis (tier 1). Methodologic quality varied, but did not affect diagnostic accuracy. In tier 1 studies, the median prevalence of mediastinal metastasis was 34%. Using a random effects model, the pooled sensitivity and specificity were 39% (95% CI, 17% to 61%) and 99% (95% CI, 96% to 100%), respectively. Compared with tier 1 studies, median prevalence of mediastinal metastasis (81%; p=0.002) and pooled sensitivity (78%; 95% CI, 71% to 84%; p=0.009) were higher in non-tier 1 studies. Sensitivity analysis confirmed that the sensitivity of TBNA depends critically on the prevalence of mediastinal metastasis. The pooled major complication rate was 0.3% (95%CI, 0.01% to 4%).

Conclusions: When properly performed, TBNA is highly specific for identifying mediastinal metastasis in patients with NSCLC, but sensitivity depends critically on the study methods and patient population. In populations with a lower prevalence of mediastinal metastasis, the sensitivity of TBNA is much lower than reported in recent lung cancer guidelines.

Background: The current national measure set for the quality of health care underrepresents the spectrum of outpatient care and makes limited use of readily available national ambulatory care survey data.

Methods:We examined 23 outpatient quality indicators in 1992 and again in 2002 to measure overall performance and racial/ethnic disparities in outpatient care in the United States. The National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey yielded information about ambulatory services provided in private physician offices and hospital outpatient departments, respectively. Quality indicator performance was defined as the percentage of applicable visits receiving appropriate care.

Results: In 2002, mean performance was 50% or more of applicable visits for 12 quality indicators, 7 of which were in the areas of appropriate antibiotic use and avoiding unnecessary routine screening. The performance of the remaining 11 indicators ranged from 15% to 42%. Overall, changes between 1992 and 2002 were modest, with significant improvements in 6 indicators: treatment of depression (47% vs 83%), statin use for hyperlipidemia (10% vs 37%), inhaled corticosteroid use for asthma in adults (25% vs 42%) and children (11% vs 36%), avoiding routine urinalysis during general medical examinations (63% vs 73%), and avoiding inappropriate medications in the elderly (92% vs 95%). After adjusting for potential confounders, race/ethnicity did not seem to affect quality indicator performance, except for greater angiotensin-converting enzyme inhibitor use for congestive health failure among blacks and less unnecessary antibiotic use for uncomplicated upper respiratory tract infections among whites.

Conclusions: Measurable quality deficits and modest improvements across time call for greater adherence to evidence-based medicine in US ambulatory settings. Although significant racial disparities have been described in a variety of settings, we observed that similar, although less than optimal, care is being provided on a per-visit basis regardless of patient racial/ethnic background.

BACKGROUND: Gender differences in health system usage can lead to differences in the incidence of morbidity and mortality. We conducted a pilot screening targeted towards men to evaluate gender differences in cardiovascular disease risk factor detection and time since last clinic visit.

METHODS: Three evening sessions in two communities screened 148 people, mean age 47.7 years. Height, weight, body mass index, blood pressure, blood glucose, and total cholesterol were measured. A questionnaire on past medical history was administered. Participants with elevated measurements were referred to appropriate care.

RESULTS: Men accounted for 60.1% of those screened; 65.5% of the group was overweight, and 22.3% was obese with 42.6% hypertension, 39.2% hypercholesterolemia, and 2.7% high blood glucose. Among men aged 35 to 65, 65.2% were overweight, 20.3% obese, 46.4% hypertensive, 42.0% hypercholesterolemic, and 1.5% with high blood glucose. Within the last 2 years, 53.3% of men and 9.1% of women aged 35 to 65 had not visited a doctor (P = 0.004).

CONCLUSIONS: A significant portion of those screened had elevated cardiovascular disease risk factors. Given that men visited doctors significantly less frequently, efforts to involve men in prevention of cardiovascular disease within these communities are warranted.

Objective: To assess the functional and behavioral health of unaccompanied Sudanese refugee minors approximately 1 year after resettlement in the United States.

Design: A descriptive survey.

Setting: Local refugee foster care programs affiliated with the US Unaccompanied Refugee Minors Program.

Participants: A total of 304 Sudanese refugee minors enrolled in the US Unaccompanied Refugee Minors Program.

Main Outcome Measures: Health outcomes were assessed using the Harvard Trauma Questionnaire and the Child Health Questionnaire. Outcomes included the diagnosis of posttraumatic stress disorder and scores on all Child Health Questionnaire subscales and global single-item assessments.

Results: Twenty percent of the minors had a diagnosis of posttraumatic stress disorder and were more likely to have lower (worse) scores on all the Child Health Questionnaire subscales. Low functional and behavioral health scores were seen mainly in functioning in the home and in subjective health ratings. Social isolation and history of personal injury were associated with posttraumatic stress disorder.

Conclusions: Unaccompanied Sudanese minors have done well in general. The minors function well in school and in activities; however, behavioral and emotional problems manifest in their home lives and emotional states. The subset of children with traumatic symptoms had characteristics that may distinguish them from their peers and that may inform future resettlement services for unaccompanied minors in the United States.

BACKGROUND: Only limited research tracks United States trends in the use of statins recorded during outpatient visits, particularly use by patients at moderate to high cardiovascular risk.

METHODS AND FINDINGS: Data collected between 1992 and 2002 in two federally administered surveys provided national estimates of statin use among ambulatory patients, stratified by coronary heart disease risk based on risk factor counting and clinical diagnoses. Statin use grew from 47% of all lipid-lowering medications in 1992 to 87% in 2002, with atorvastatin being the leading medication in 2002. Statin use by patients with hyperlipidemia, as recorded by the number of patient visits, increased significantly from 9% of patient visits in 1992 to 49% in 2000 but then declined to 36% in 2002. Absolute increases in the rate of statin use were greatest for high-risk patients, from 4% of patient visits in 1992 to 19% in 2002. Use among moderate-risk patients increased from 2% of patient visits in 1992 to 14% in 1999 but showed no continued growth subsequently. In 2002, 1 y after the release of the Adult Treatment Panel III recommendations, treatment gaps in statin use were detected for more than 50% of outpatient visits by moderate- and high-risk patients with reported hyperlipidemia. Lower statin use was independently associated with younger patient age, female gender, African American race (versus non-Hispanic white), and non-cardiologist care.

CONCLUSION: Despite notable improvements in the past decade, clinical practice fails to institute recommended statin therapy during many ambulatory visits of patients at moderate-to-high cardiovascular risk. Innovative approaches are needed to promote appropriate, more aggressive statin use for eligible patients.

The incidence of obesity has increased dramatically in the U.S. Obese individuals tend to be sicker and spend more on health care, raising the question of who bears the incidence of obesity-related health care costs. This question is particularly interesting among those with group coverage through an employer given the lack of explicit risk adjustment of individual health insurance premiums in the group market. In this paper, we examine the incidence of the healthcare costs of obesity among full time workers. We find that the incremental healthcare costs associated with obesity are passed on to obese workers with employer-sponsored health insurance in the form of lower cash wages. Obese workers in firms without employer-sponsored insurance do not have a wage offset relative to their non-obese counterparts. Our estimate of the wage offset exceeds estimates of the expected incremental health care costs of these individuals for obese women, but not for men. We find that a substantial part of the lower wages among obese women attributed to labor market discrimination can be explained by the higher health insurance premiums required to cover them.
