Economic perspective on strategic human capital management and planning for the Centers for Disease Control and Prevention.

An organization's workforce--or human capital--is its most valuable asset. The 2002 President's Management Agenda emphasizes the importance of strategic human capital management by requiring all federal agencies to improve performance by enhancing personnel and compensation systems. In response to these directives, the Centers for Disease Control and Prevention (CDC) drafted its strategic human capital management plan to ensure that it is aligned strategically to support the agency's mission and its health protection goals. In this article, we explore the personnel economics literature to draw lessons from research studies that can help CDC enhance its human capital management and planning. To do so, we focus on topics that are of practical importance and empirical relevance to CDC's internal workforce and personnel needs with an emphasis on identifying promising research issues or methodological approaches. The personnel economics literature is rich with theoretically sound and empirically rigorous approaches for shaping an evidence-based approach to human capital management that can enhance incentives to attract, retain, and motivate a talented federal public health workforce, thereby promoting the culture of high-performance government.

Perspectives on public health workforce research.

The Centers for Disease Control and Prevention Office of Workforce and Career Development is committed to developing a competent, sustainable, and diverse public health workforce through evidence-based training, career and leadership development, and strategic workforce planning to improve population health outcomes. This article reviews the previous efforts in identifying priorities of public health workforce research, which are summarized as eight major research themes. We outline a strategic framework for public health workforce research that includes six functional areas (ie, definition and standards, data, methodology, evaluation, policy, and dissemination and translation). To conceptualize and prioritize development of an actionable public health research agenda, we constructed a matrix of key challenges in workforce analysis by public health workforce categories. Extensive reviews were conducted to identify valuable methods, models, and approaches to public health workforce research. We explore new tools and approaches for addressing priority areas for public health workforce and career development research and assess how tools from multiple disciplines of social sciences can guide the development of a research framework for advancing public health workforce research and policy.

Breath acidification in adolescent runners exposed to atmospheric pollution: a prospective, repeated measures observational study.

BACKGROUND: Vigorous outdoors exercise during an episode of air pollution might cause airway inflammation. The purpose of this study was to examine the effects of vigorous outdoor exercise during peak smog season on breath pH, a biomarker of airway inflammation, in adolescent athletes. METHODS: We measured breath pH both pre- and post-exercise on ten days during peak smog season in 16 high school athletes engaged in daily long-distance running in a downwind suburb of Atlanta. The association of post-exercise breath pH with ambient ozone and particulate matter concentrations was tested with linear regression. RESULTS: We collected 144 pre-exercise and 146 post-exercise breath samples from 16 runners (mean age 14.9 years, 56% male). Median pre-exercise breath pH was 7.58 (interquartile range: 6.90 to 7.86) and did not change significantly after exercise. We observed no significant association between ambient ozone or particulate matter and post-exercise breath pH. However both pre- and post-exercise breath pH were strikingly low in these athletes when compared to a control sample of 14 relatively sedentary healthy adults and to published values of breath pH in healthy subjects. CONCLUSION: Although we did not observe an acute effect of air pollution exposure during exercise on breath pH, breath pH was surprisingly low in this sample of otherwise healthy long-distance runners. We speculate that repetitive vigorous exercise may induce airway acidification.

Mental health, social functioning, and disability in postwar Afghanistan.

CONTEXT: More than 2 decades of conflict have led to widespread human suffering and population displacement in Afghanistan. In 2002, the Centers for Disease Control and Prevention and other collaborating partners performed a national population-based mental health survey in Afghanistan. OBJECTIVE: To provide national estimates of mental health status of the disabled (any restriction or lack of ability to perform an activity in the manner considered normal for a human being) and nondisabled Afghan population aged at least 15 years. DESIGN, SETTING, AND PARTICIPANTS: A national multistage, cluster, population-based mental health survey of 799 adult household members (699 nondisabled and 100 disabled respondents) aged 15 years or older conducted from July to September 2002. Fifty district-level clusters were selected based on probability proportional to size sampling. One village was randomly selected in each cluster and 15 households were randomly selected in each village, yielding 750 households. MAIN OUTCOME MEASURES: Demographics, social functioning as measured by selected questions from the Medical Outcomes Study 36-Item Short-Form Health Survey, depressive symptoms measured by the Hopkins Symptoms Checklist-25, trauma events and symptoms of posttraumatic stress disorder (PTSD) measured by the Harvard Trauma Questionnaire, and culture-specific symptoms of mental illness and coping mechanisms. RESULTS: A total of 407 respondents (62.0%) reported experiencing at least 4 trauma events during the previous 10 years. The most common trauma events experienced by the respondents were lack of food and water (56.1%) for nondisabled persons and lack of shelter (69.7%) for disabled persons. The prevalence of respondents with symptoms of depression was 67.7% (95% confidence interval [CI], 54.6%-80.7%) and 71.7% (95% CI, 65.0%-78.4%), and symptoms of anxiety 72.2% (95% CI, 63.8%-80.7%) and 84.6% (95% CI, 74.1%-95.0%) for nondisabled and disabled respondents, respectively. The prevalence of symptoms of PTSD was similar for both groups (nondisabled, 42.1%; 95% CI, 34.2%-50.1%; and disabled, 42.2%; 95% CI, 29.2%-55.2%). Women had significantly poorer mental health status than men did. Respondents who were disabled had significantly lower social functioning and poorer mental health status than those who were nondisabled. Feelings of hatred were high (84% of nondisabled and 81% of disabled respondents). Coping mechanisms included religious and spiritual practices; focusing on basic needs, such as higher income, better housing, and more food; and seeking medical assistance. CONCLUSIONS: In this nationally representative survey of Afghans, prevalence rates of symptoms of depression, anxiety, and PTSD were high. These data underscore the need for donors and health care planners to address the current lack of mental health care resources, facilities, and trained mental health care professionals in Afghanistan.

Mental health symptoms following war and repression in eastern Afghanistan.

CONTEXT: Decades of armed conflict, suppression, and displacement resulted in a high prevalence of mental health symptoms throughout Afghanistan. Its Eastern province of Nangarhar is part of the region that originated the Taliban movement. This may have had a distinct impact on the living circumstances and mental health condition of the province's population. OBJECTIVES: To determine the rate of exposure to traumatic events; estimate prevalence rates of symptoms of posttraumatic stress disorder (PTSD), depression, and anxiety; identify resources used for emotional support and risk factors for mental health symptoms; and assess the present coverage of basic needs in Nangarhar province, Afghanistan. DESIGN, SETTING, AND PARTICIPANTS: A cross-sectional multicluster sample survey of 1011 respondents aged 15 years or older, conducted in Nangarhar province during January and March 2003; 362 households were represented with a mean of 2.8 respondents per household (72% participation rate). MAIN OUTCOME MEASURES: Posttraumatic stress disorder symptoms and traumatic events using the Harvard Trauma Questionnaire; depression and general anxiety symptoms using the Hopkins Symptom Checklist; and resources for emotional support through a locally informed questionnaire. RESULTS: During the past 10 years, 432 respondents (43.7%) experienced between 8 and 10 traumatic events; 141 respondents (14.1%) experienced 11 or more. High rates of symptoms of depression were reported by 391 respondents (38.5%); anxiety, 524 (51.8%); and PTSD, 207 (20.4%). Symptoms were more prevalent in women than in men (depression: odds ratio [OR], 7.3 [95% confidence interval [CI], 5.4-9.8]; anxiety: OR, 12.8 [95% CI, 9.0-18.1]; PTSD: OR, 5.8 [95% CI, 3.8-8.9]). Higher rates of symptoms were associated with higher numbers of traumas experienced. The main resources for emotional support were religion and family. Medical care was reported to be insufficient by 228 respondents (22.6%). CONCLUSIONS: In this survey of inhabitants of Nangarhar province, Afghanistan, prevalence rates of having experienced multiple traumatic events and having symptoms of anxiety, depression, and PTSD were high. These findings suggest that mental health symptoms in this region should be addressed at the population and primary health care level.
