A STUDY ON THE EPIDEMIOLOGY OF POSITIVE PHYSICAL HEALTH (NHANES I)

HANES 1 detailed sample data were used to operationalize a definition of health in the absence of disease and to describe and compare the characteristics of the normal (healthy) group versus an abnormal (unhealthy) group.^ Parallel screening gave a 3.8 percent prevalence proportion of physical health, with a female:male ratio of 2:1 and younger ages in the healthy group. Statistically significant Mantel-Haenszel gender-age-adjusted odds ratios (MHOR) were estimated among abnormal non-migrants (1.53), skilled workers/unemployed (1.76), annual family incomes of less than $10,000 (1.56), having ever smoked (1.58), and started smoking before 18 years of age (1.58). Significant MHOR were also found for abnormals for health promoting measures: non-iodized salt use (1.94), needed dental care (1.91); and for fair to poor perceived health (4.28), perceiving health problems (2.52), and low energy level (1.68). Significant protective effects for much to moderate recreational exercise (MHOR 0.42) and very active to moderate non-recreational activity (MHOR 0.49) were also obtained. Covariance analysis additive models detected statistically significant higher mean values for abnormals than normals for serum magnesium, hemoglobin, hematocrit, urinary creatinine, and systolic and diastolic blood pressures, and lower values for abnormals than normals for serum iron. No difference was detected for serum cholesterol. Significant non-additive joint effects were found for body mass index.^ The results suggest positive physical health can be measured with cross-sectional survey data. Gender differentials, and associations between ecologic, socioeconomic, hazardous risk factors, health promoting activities and physical health are in general agreement with published findings on studies of morbidity. Longitudinal prospective studies are suggested to establish the direction of the associations and to enhance present knowledge of health and its promoting factors. ^

Formative Evaluation of the "Time Twisters": A Comic Book Based Obesity Prevention Curriculum for Elementary School Students

Introduction: Obesity is a public health problem, particularly in Hispanic children. Alternative media channels may offer the potential to motivate children to engage in health promoting behaviors. A comic book, “Time Twisters”, was developed to impact screen time use, physical activity, and dietary behavior for elementary school children and evaluated for acceptability and feasibility prior to implementation in a multi-component physical activity intervention.

Physician's adherence to CDC standards for physical activity counseling of older women in a cardiology practice in Texas---An exploratory study

Physical activity is an important health-promoting behavior to prevent and control chronic disease. Interventions to increase physical activity are vitally needed. Women are not meeting the recommended goals for physical activity - a behavior that has been shown to effectively reduce the incidence of chronic disease and the medical costs associated with treating it. Among many factors predicting physical activity and the different forms of interventions that have been applied, physician counseling is one potentially cost-effective approach that may produce at least modest effects on women's behavior. The Centers for Disease Control and Prevention has published standards for physician counseling of patients regarding physical activity. This study used a short questionnaire to assess the degree to which a group practice of cardiology physicians in Texas queried and discussed physical activity recommendations to older women that they treat and whether they are meeting the physical activity counseling goals of the Centers for Disease Control and Prevention. The majority of this group of physicians counseled patients without benefit of exploring patient behavior. Although these physicians "agreed" that physical activity delayed or prevented disease, the outcome suggests that low self-efficacy hampered efforts to counsel older women on this. Physicians' perceptions that counseling may be ineffective could explain the lower rate of physical activity counseling that does not meet the goals of the Centers for Disease Control and Prevention. ^

Goals, plans, and behavior changes: A relevant part of the post-treatment cancer experience

Background. Colorectal cancer (CRC) survivors have to manage treatment side effects, psychosocial issues, and co-morbidities, as well as modify their lifestyles to decrease risk of recurrence and prolong life. Identifying survivors’ goals and key factors that influence their goals will highlight the issues cancer survivors face post-treatment and the resources needed to help them engage in health-promoting behaviors.^ Objectives and methods. This dissertation examines the health-related goals of post-treatment CRC survivors using two studies: (1) a qualitative study to identify and describe the health goals of CRC survivors during the transition from active treatment to post-treatment survivorship and follow-up care; and (2) a cross-sectional survey to identify CRC survivors’ goals, and key factors that influence their goals.^ Results. (1) The 41 qualitative interviews indicated participants’ health-related goals were to be healthy, get back to normal, and not have a cancer recurrence. Most of the CRC survivors reported they maintained healthy behaviors, made healthy behavior changes, or had goals to change their behavior. Respondents were empowered to improve their health by maintaining follow-up care and regular health screenings, and many were managing treatment side effects in an effort to improve functional abilities. (2) The cross-sectional study found that CRC survivors’ most prevalent goals were related to healthy behaviors (i.e., eat a healthy diet and engage in physical activity), and cancer care or disease management (i.e., keep up with health screenings and monitor symptoms). Goals that survivors identified as important were similar to goals they perceived were important to their providers (i.e., goals related to cancer care, disease management). Certain goals were statistically associated with age, barriers to achieving goals, social support and health-related quality of life.^ Conclusions. CRC survivors have health-promoting goals post-treatment and are interested in making health behavior changes. Goals ranged from cancer care/surveillance and disease management to healthy lifestyle modifications. Patients may need help resolving or managing treatment side effects or co-morbidities prior to implementing health promoting behaviors. Healthcare providers’ recommendations may be a powerful resource to encourage survivors to engage in health-promoting behaviors. Self-management and goal setting support could be an appropriate strategy to assist patients with achieving their post-treatment health goals.^

New Journal, Same Ongoing Challenge: Advancing Policies that Promote the Health and Well-Being of Children and Families

The publication of the inaugural issue of the Journal of Applied Research on Children is a notable milestone for its sponsoring organization, CHILDREN AT RISK (www.childrenatrisk.org). With the release of “Volume 1, Number 1,” we as the Co-Editors in Chief would like to take the opportunity to thank the inaugural contributors whose articles follow and to answer the obvious question of “Why publish a new journal?”

Occupational beryllium exposure: Reconciling federal policies, regulations and contractor implementation guides to protect worker health

Beryllium is a widely distributed, highly toxic metal. When beryllium particulates enter the body, the body's defense mechanisms are engaged. When the body's defenses cannot easily remove the particulates, then a damage and repair cycle is initiated. This cycle produces chronic beryllium disease (CBD), a progressive, fibrotic respiratory involvement which eventually suffocates exposed individuals. ^ Beryllium disease is an occupational disease, and as such it can be prevented by limiting exposures. In the 1940s journalists reported beryllium deaths at Atomic Energy Commission (AEC) facilities, the Department of Energy's (DOE) predecessor organization. These reports energized public pressure for exposure limits, and in 1949 AEC implemented a 2 μg/m3 permissible exposure limit (PEL). ^ The limits appeared to stop acute disease. In contrast, CBD has a long latency period between exposure and diagnosable disease, between one and thirty years. The lack of immediate adverse health consequences masked the seriousness of chronic disease and pragmatically removed CBD from AEC/DOE's political concern. ^ Presently the PEL for beryllium at DOE sites remains at 2 μg/m 3. This limit does not prevent CBD. This conclusion has long been known, although denied until recently. In 1999 DOE acknowledged the limit's ineffectiveness in its federal regulation governing beryllium exposure, 10 CFR 850. ^ Despite this admission, the PEL has not been reduced. The beryllium manufacturer and AEC/DOE have a history of exerting efforts to maintain and protect the status quo. Primary amongst these efforts has been creation and promotion of disinformation within peer reviewed health literature which discusses beryllium, exposures, health effects and treatment, and targeting graduate school students so that their perspective is shaped early. ^ Once indoctrinated with incorrect information, professionals tend to overlook aerosol and respiratory mechanics, immunologic and carcinogenic factors. They then apply tools and perspectives derived from the beryllium manufacturer and DOE's propaganda. Conclusions drawn are incorrect. The result is: health research and associated policy is conducted with incorrect premises. Effective disease management practices are not implemented. ^ Public health protection requires recognition of the disinformation and its implications. When disinformation is identified, then effective health policies and practices can be developed and implemented. ^

Ago-TNRC6 triggers microRNA-mediated decay by promoting two deadenylation steps.

MicroRNAs (miRNAs) silence the expression of their mRNA targets mainly by promoting mRNA decay. The mechanism, kinetics and participating enzymes for miRNA-mediated decay in mammalian cells remain largely unclear. Combining the approaches of transcriptional pulsing, RNA tethering, overexpression of dominant-negative mutants, and siRNA-mediated gene knockdown, we show that let-7 miRNA-induced silencing complexes (miRISCs), which contain the proteins Argonaute (Ago) and TNRC6 (also known as GW182), trigger very rapid mRNA decay by inducing accelerated biphasic deadenylation mediated by Pan2-Pan3 and Ccr4-Caf1 deadenylase complexes followed by Dcp1-Dcp2 complex-directed decapping in mammalian cells. When tethered to mRNAs, all four human Ago proteins and TNRC6C are each able to recapitulate the two deadenylation steps. Two conserved human Ago2 phenylalanines (Phe470 and Phe505) are critical for recruiting TNRC6 to promote deadenylation. These findings indicate that promotion of biphasic deadenylation to trigger mRNA decay is an intrinsic property of miRISCs.

Sexual Health Education from the Perspective of School Staff: Implications for Adoption and Implementation of Effective Programs in Middle School

Introduction: US teens are having sex early; however, the vast majority of schools do not implement evidence-based sexual health education (SHE) programs that could delay sexual behavior and/or reduce risky behavior. This study examines middle school staff’s knowledge, attitudes, barriers, self-efficacy, and perceived support (psychosocial factors known to influence SHE program adoption and implementation). Methods: Professional school staff from 33 southeast Texas middle schools completed an internet or paper-based survey. Prevalence estimates for psychosocial variables were computed for the total sample. Chi-square and t-test analyses examined variation by demographic factors. Results: Almost 70% of participants were female, 37% white, 42% black, 16% Hispanic; 20% administrators, 15% nurses/counselors, 31% non-physical education/non-health teachers, 28% physical education/health teachers; mean age = 42.78 years (SD = 10.9). Over 90% favored middle school SHE, and over 75% reported awareness of available SHE curricula or policies. More than 60% expressed confidence for discussing SHE. Staff perceived varying levels of administrator (28%-56%) support for SHE and varying levels of support for comprehensive sex education from outside stakeholders (e.g., parents, community leaders) (42%-85%). Overall, results were more favorable for physical education/health teachers, nurses/counselors, and administrators (when compared to non-physical education/non-health teachers) and individuals with experience teaching SHE. Few significant differences were observed by other demographic factors. Conclusions: Overall, study results were extremely positive, which may reflect a high level of readiness among school staff for adopting and implementing effective middle school SHE programs. Study results highlight the importance of several key action items for schools.

'Reform' of the British national health service after the election of a labour government: Understanding the policy development process

The policy development process leading to the Labour government's white paper of December 1997—The new NHS: Modern, Dependable—is the focus of this project and the public policy development literature is used to aid in the understanding of this process. Policy makers who had been involved in the development of the white paper were interviewed in order to acquire a thorough understanding of who was involved in this process and how they produced the white paper. A theoretical framework is used that sorts policy development models into those that focus on knowledge and experience, and those which focus on politics and influence. This framework is central to understanding the evidence gathered from the individuals and associations that participated in this policy development process. The main research question to be asked in this project is to what extent do either of these sets of policy development models aid in understanding and explicating the process by which the Labour government's policies were developed. The interview evidence, along with published evidence, show that a clear pattern of policy change emerged from this policy development process, and the Knowledge-Experience and Politics-Influence policy making models both assist in understanding this process. The early stages of the policy development process were characterized as hierarchical and iterative, yet also very collaborative among those participating, with knowledge and experience being quite prevalent. At every point in the process, however, informal networks of political influence were used and noted to be quite prevalent by all of the individuals interviewed. The later stages of the process then became increasingly noninclusive, with decisions made by a select group of internal and external policy makers. These policy making models became an important tool with which to understand the policy development process. This Knowledge-Experience and Politics-Influence dichotomy of policy development models could therefore be useful in analyzing other types of policy development. ^

Intervening to reach adolescents and affect health

Background. Assessing the health status of adolescents is challenging for health care providers. Personal disclosure has been associated with improved health outcomes. Story-centered care was examined as an intervention for promoting adolescent disclosure during an urgent care visit. ^ Objectives. This study explored: (1) the effectiveness of story-centered care for promoting adolescent disclosure; (2) health-associated words used by adolescents to describe pressing concerns after an urgent care visit when they had standard care (SC) or story-centered care (SCC) conducted by a Nurse Practitioner (NP). ^ Methods. Subjects were randomly assigned to SC or SCC. In SC, adolescent presenting concerns were identified and treated. In SCC, presenting concerns were treated and NP-adolescent dialogue, facilitated through a screening tool, queried matters of importance to adolescent life. After the visit, adolescents wrote about pressing concerns for 15 minutes. Written words were analyzed with Linguistic Inquiry and Word Count, a software program for analyzing narrative. Ratios were calculated for the number of words (adolescent: NP) used during the urgent care visit. Analysis of variance (ANOVA) was used to evaluate gender-intervention differences in health-associated words. ^ Results. One hundred and six adolescents [Hispanic (65%), White (35%)] completed the study. Fifty-five were female; the average age was 17 (sd = 2.1) years. ^ Adolescents in the story intervention used more words (adolescent: NP, 1:1.3) than those in standard intervention (adolescent: NP, 1:2.7) in proportion to the number of words used by the NP during the urgent care visit. There were gender-intervention differences (p < .01) in positive emotion words and past-tense words in writings about pressing concerns. Males who received the story intervention used more positive emotion and less past-tense words than adolescent males with standard care. Females used more social words (p < .01) in their writings regardless of intervention group. ^ Conclusion. SCC enhanced adolescent disclosure during an urgent care visit. Adolescents will talk to health care providers during episodic visits and males may benefit more than girls may from this approach. Evidence suggests there is value in attending to both presenting and pressing concerns of adolescents. ^

The emergence of the social determinants of health on the policy agenda in Britain: A case study, 1980--2003

Numerous theories have been advanced in the effort to explain how a given policy issue manages to take root in the public sphere and subsequently move forward on the public legislative agenda—or not. This study examined how the social determinants of health (SDOH) came to be part of the legislative policy agenda in Britain from 1980 to 2003. ^ The specific objectives of the research were: (1) to conduct a sociopolitical analysis grounded in alternative agenda-setting theories to identify the factors responsible for moving the social determinants health perspective onto the British policy agenda; and (2) to determine which of the theories and related dimensions best accounted for the emergence of this perspective. ^ A triangulated content and context analysis of British news articles, historical accounts, and research commentaries of the SDOH movement was conducted guided by relevant agenda-setting theories set within a social movement framework to chronicle the emergence of the SDOH as a significant policy issue in Britain. ^ The most influential social movement and agenda setting elements in the emergence of the SDOH in Britain were issue generation tactics, framing efforts, mobilizing structures, and political opportunities grounded in social movement and agenda setting theories. Policy content or the details of the policy had comparatively little impact on the successful emergence of the SDOH. Despite resistance by the government, from 1980 to 1996 interest groups created a political understanding of the SDOH utilizing a framing package encompassing notions of inequality, fairness, and justice. This frame transmitted a powerful idea connected to a core set of British values and beliefs. After 1996, a shift in political opportunities cemented the institutional arrangements needed to sustain an environment conducive to the development and implementation of SDOH policies and programs. ^ This research demonstrates that the U.S. emergence of the SDOH on the policy agenda will depend upon: (1) U.S. ideals and values regarding poverty, inequality, race, health, and health care that will determine issue framing; (2) political opportunities that will emerge—or not—to advance the SDOH policy agenda; and (3) the mobilizing structures that support or oppose the issue. ^

The construction of aging and health in older African American women

Persistence of racial and ethnic health disparities and governmental policies based on outdated ideas of aging call for inclusive approaches to the study of elder African Americans. The lived experiences of aging among urban, poor African American women, who comprise a vulnerable population, are not well known, as most studies focus on mainstream populations. Gerontological studies have tended to employ methods that collapse contextual information for ease of analysis, thus failing to capture nuanced information critically relevant to health of marginalized groups. Few researchers have been successful highlighting the importance of local knowledge, resilience, and resources for health by using participatory methods with older Black women. This study utilizes participatory principles to gather discursive data from nine older African American women, engaged in three generational cohorts: those born around World War II, women born after the great depression, and those born before the great depression. Videotaped and transcribed conversations of cohorts were analyzed in search of contextual factors that influence their experience of aging and health. As women responded to general themes that provoked their talk about their lives, they helped answer the study's questions: How do older African American women make sense of their aging experience? What are some of the important social and cultural influences that shape the construction of aging and health by these women? Are generational discourse groups an effective tool for exploring changes in the experiences of aging? A key finding demonstrated rich heterogeneity of experiences with strong generational influences on the construction of aging and health. The participants' moral orders comprised of traditional values of family, reinforced by personal experiences and the church, have guided their lives through oppression and stress but appear to be failing younger women who have greater exposure to new environmental pressures. Limited time and the size of the study were weaknesses although the women's interest in the study and their participation were gratifying. The participants served to highlight the importance of recognizing generational and other contextual factors in formation of ideas of aging and likelihood of additional challenges to the experience of old age among older, poorer, African Americans. ^

Government initiatives to expand access to employer-based health insurance

Employer-based health insurance is declining at records rates, which leaves an increasing number of people without access to affordable health insurance. As a result, municipalities are experiencing financial difficulties to provide health care services for their growing uninsured population. In attempt to combat this issue, three health polices have emerged within the last ten years, called Living Wage with a health insurance provision, Pay or Play, and Health Care Preference. These policies are gaining popularity as civic leaders recognize their ability to promote a public health goal by leveraging the power of city and county contracts to include a health insurance component in the competitive bidding practice for government contracts. ^ This is the first paper to conduct a retrospective analysis on whether these three health policies have been able to increase access to employer-based health insurance and/or support the local health care safety net based on the experiences of six municipalities over a 5-year period from 2001-2006. Although there was variation between the effectiveness of the policies, all three demonstrated success in that a number of contractors extended existing health insurance to employees not previously covered and the increased cost of contracting for the local government was, on average, less than 1 percent of the total operating budget. ^

Current United States stem cell policy considerations and a recommendation for an alternative policy based on guidelines from existing international policies

Embryonic stem cell research is a widely debated topic in modern politics and religion. Differing views on the fetal rights conflict with the rights of an embryo. Those who believe an embryo has the same human qualities as a fetus accordingly believe embryonic stem cell research is unethical because it destroys a potential human life. However, scientists advocate the embryo does not have human qualities and should be used for valuable research in the stem cell field. Stem cell research may lead to vast developments in medical treatments, including cancer and brain conditions and injuries that are currently incurable. ^ The current stem cell policy introduced by President Bush in 2001 in an attempt to balance the moral issues with the need for scientific research has broad negative implications on the furthering of stem cell research. There is a limited diversity of available stem cell lines, there may be constitutional issues, there is an increasing disparity between the public and private research spheres, and the U.S. is struggling to maintain its scientific community. The U.S. must develop a new stem cell research policy that will balance the interest of science and public health with the moral issues that concern the public. ^ The United Kingdom allows researchers great liberty in conducting research, permitting the creation of embryos for the sole purpose of research, while Germany is equally conservative in their laws, as their policies support the philosophy that all embryos deserve the protection of full life. The United States should adopt a policy that takes the "middle ground" approach and permit research on excess embryos created for IVF purposes, rather than simply discarding those potentially valuable research tools. ^

Hospital and environmental variation in Texas nonprofit hospital organizational policies regarding charity care

The 2005 Annual Statement of Community Benefits Standard (ASCBS) and the annual report of the Community Benefits Plan, Summary of Current Hospital Charity Care Policy and Community Benefits, were used to identify various environmental and policy relationships with regard to eligibility for charity care requirements, a component for meeting the nonprofit requirements established by the Texas Legislature for nonprofit tax exemption (Texas Health and Safety Code, §311.04610). ^ Charity care policies are established by the individual hospital (or systems) and are generally defined as rules concerning care provided by the institution without the expectation of payment. This study has been undertaken to provide specific information about the charity care eligibility requirement policies of nonprofit hospitals. These hospitals are the part of the safety net for those persons who are indigent, low-income and uninsured. This study examines nonprofit hospitals by physical location, bed size, religious affiliation, trauma level, disproportionate share, and teaching designations. County information includes population, percentage of residents eligible for Medicaid benefits, ethnic makeup of county residents, poverty level, designation of a hospital district or operators of a public hospital, and the number of nonprofit and for-profit hospitals located in the county. Although this information has been collected by the Texas Department of State Health Services (DSHS), no other analysis has been conducted. ^
