Association Between System Factors and Acute Myocardial Infarction Mortality.

Objectives: We conducted a cross-sectional study to assess the association between healthcare system factors and death from acute myocardial infarction (AMI), in terms of access (distance to the hospital, mode of transportation), availability (emergency medical services, hospitals), and capability (emergency medical services' 12-lead electrocardiogram capability, continuous percutaneous coronary intervention [PCI] and cardiothoracic surgical services), after accounting for individual and environmental factors.

Methods: Data on 14,663 deaths (in-hospital and out of hospital) and live hospital discharges as a result of AMI for 2012 and 2013 among Arkansas residents were obtained from the Arkansas Department of Health. A mixed-effects logistic regression model was used to account for nesting, in which an individual was nested within either a county or a hospital to evaluate the association of system factors with death from AMI.

The influence of propoxyphene withdrawal on opioid use in veterans.

Purpose: Our aim is to determine if propoxyphene withdrawal from the US market was associated with opioid continuation, continued chronic opioid use, and secondary propoxyphene-related adverse events (emergency department visits, opioid-related events, and acetaminophen toxicity).

Methods: Medical service use and pharmacy data from 19/11/08 to 19/11/11 were collected from the national Veterans Healthcare Administration healthcare databases. A quasi-experimental pre-post retrospective cohort design utilizing a historical comparison group provided the study framework.

Cross-sectional study to assess the association of population density with predicted breast cancer risk.

The Gail and CARE models estimate breast cancer risk for white and African-American (AA) women, respectively. The aims of this study were to compare metropolitan and nonmetropolitan women with respect to predicted breast cancer risks based on known risk factors, and to determine if population density was an independent risk factor for breast cancer risk. A cross-sectional survey was completed by 15,582 women between 35 and 85 years of age with no history of breast cancer.

Strength training in community settings: impact of lay leaders on program access and sustainability for rural older adults.

Background: The effect of volunteer lay leaders on availability and sustainability of strength-training programs for older adults has not been well explored. We describe implementation of the StrongWomen strength training program by the Arkansas Cooperative Extension Service, and report on the relationship between delivery approach (agent-led, lay-led, or combination of agent- and lay-led) and program access and sustainability.

Methods: All state Extension agents (n = 66) were surveyed on program implementation, continuance, and use of lay leaders.

The evaluation of Arkansas Act 1220 of 2003 to reduce childhood obesity: conceptualization, design, and special challenges.

This article describes the evaluation of the Arkansas Act 1220 of 2003, a comprehensive legislative proposal to address the growing epidemic of childhood obesity through changes in the school environment. In addition, the article discusses specific components of the evaluation that may be applicable to other childhood obesity policy evaluation efforts. The conceptual framework for the evaluation, research questions, and evaluation design are described, along with data collection methods and analysis strategies.

Creating and using index scores in the analysis of school policy implementation and impact.

Background: Epidemic increases in childhood obesity and associated health risks are resulting in efforts to implement school policies related to nutrition and physical activity (NPA). With multicomponent policy efforts, challenges exist in characterizing the extent of policy change across the breadth of NPA policies.

Methods: Aggregated policy indices were created to characterize NPA policy implementation in Arkansas public schools from 2004 through 2009.

Public policy versus individual rights in childhood obesity interventions: perspectives from the Arkansas experience with Act 1220 of 2003.

Childhood obesity is a major public health problem. Experts recommend that prevention and control strategies include population-based policies. Arkansas Act 1220 of 2003 is one such initiative and provides examples of the tensions between individual rights and public policy.

Development and evaluation of the school cafeteria nutrition assessment measures.

Background: Foods provided in schools represent a substantial portion of US children's dietary intake; however, the school food environment has proven difficult to describe due to the lack of comprehensive, standardized, and validated measures.

Methods: As part of the Arkansas Act 1220 evaluation project, we developed the School Cafeteria Nutrition Assessment (SCNA) measures to assess food availability in public school cafeterias (n = 113). The SCNA provides a measure to evaluate monthly school lunch menus and to observe foods offered in school cafeterias during the lunch period.

Establishment of a southern breast cancer cohort.

Breast cancer continues to be among the most common cancers affecting women in the United States. Researchers investigating the area are turning their attention to novel prevention, detection, and treatment options. Recent molecular epidemiology research has highlighted the effects of both genetic and environmental exposures on an individual's risk of developing breast cancer and predicted response to treatment.

Social services utilization and need among a community sample of persons living with HIV in the rural south.

HIV prevalence has increased faster in the southern USA than in other areas, and persons living with HIV (PLWHIV) in the south are often rural, impoverished, or otherwise under-resourced. Studies of urban PLWHIV and those receiving medical care suggest that use of social services can enhance quality of life and some medical outcomes, but little is known about patterns of social service utilization and need among rural southern PLWHIV. The AIDS Alabama needs assessment survey, conducted in 2007, sampled a diverse community cohort of 476 adult PLWHIV representative of the HIV-positive population in Alabama (66% male, 76% Black, and 26% less than high school education).

Public health professionals as policy entrepreneurs: Arkansas's childhood obesity policy experience.

In response to a nationwide rise in obesity, several states have passed legislation to improve school health environments. Among these was Arkansas's Act 1220 of 2003, the most comprehensive school-based childhood obesity legislation at that time. We used the Multiple Streams Framework to analyze factors that brought childhood obesity to the forefront of the Arkansas legislative agenda and resulted in the passage of Act 1220.

Changes in school environments with implementation of Arkansas Act 1220 of 2003.

Changes in school nutrition and physical activity policies and environments are important to combat childhood obesity. Arkansas Act 1220 of 2003 was among the first and most comprehensive statewide legislative initiatives to combat childhood obesity through school-based change. Annual surveys of principals and superintendents have been analyzed to document substantial and important changes in school environments, policies, and practices.

Overweight children, weight-based teasing and academic performance.

Background: School performance of overweight children has been found to be inferior to normal weight children; however, the reason(s) for this link between overweight and academic performance remain unclear. Psychosocial factors, such as weight-based teasing, have been proposed as having a possible mediating role, although they remain largely unexplored.

Methods: Random parental telephone survey data (N=1 071) of public school students collected as part of the statewide evaluation of Arkansas Act 1220, a law to reduce childhood obesity, were used.

Promoting dietary change among state health employees in Arkansas through a worksite wellness program: the Healthy Employee Lifestyle Program (HELP).

Introduction: Maintaining a healthy and productive workforce is essential for employers in public and private sectors. Poor nutrition and obesity contribute to chronic diseases and influence health care costs and productivity. Research indicates that eating a healthy diet is associated with lower body mass index and reduced risk for developing chronic disease.

Arkansas Act 1220 of 2003 to reduce childhood obesity: its implementation and impact on child and adolescent body mass index.

Arkansas was among the first states to pass comprehensive legislation to combat childhood obesity, with Arkansas Act 1220 of 2003. Two distinct but complementary evaluations of the process, impact, and outcomes of Act 1220 are being conducted: first, surveillance of the weight status of Arkansas children and adolescents, using the statewide data amassed from the required measurements of students' body mass indexes (BMIs); and second, an independent evaluation of the process, impact, and outcomes associated with Act 1220. Various stakeholder groups initially expressed concerns about the Act, specifically concerns related to negative social and emotional consequences for students and an excessive demand on health care.

A pilot study of diabetes education via telemedicine in a rural underserved community--opportunities and challenges: a continuous quality improvement process.

Purpose: Telemedicine technology may offer an avenue to implement diabetes self-management education (DSME) for people with diabetes in underserved rural communities. The continuous quality improvement process was used to identify the problem, collect and analyze data, and develop and implement a DSME program via telemedicine (DSME-T) in an underserved rural community.

Methods: A pilot study was conducted in 2006, implementing a DSME-T utilizing facilities at the University of Arkansas for Medical Sciences and a rural community hospital in Arkansas (Ozark Health, Inc).

No change in weight-based teasing when school-based obesity policies are implemented.

Objectives: To examine rates of weight-based teasing before initiation of school-based childhood obesity prevention policies (Arkansas Act 1220 of 2003) and during the 2 years following policy implementation, as well as demographic factors related to weight-based teasing.

Design: Analysis of consecutive random cross-sectional statewide telephone surveys conducted annually across 3 years.

Setting: Sample representative of Arkansas public school students with stratification by geographic region, school level (elementary, middle, and high school), and school size (small, medium, and large).

Parental recognition of overweight in school-age children.

Objective: Examine the accuracy of parental weight perceptions of overweight children before and after the implementation of childhood obesity legislation that included BMI screening and feedback.

Methods And Procedures: Statewide telephone surveys of parents of overweight (BMI > or = 85th percentile) Arkansas public school children before (n = 1,551; 15% African American) and after (n = 2,508; 15% African American) policy implementation were examined for correspondence between parental perception of child's weight and objective classification.

Results: Most (60%) parents of overweight children underestimated weight at baseline.

Effectiveness evaluation of the N-O-T smoking cessation program for adolescents.

Objective: To evaluate the effectiveness of the Not-On-Tobacco Program.

Methods: Forty-four high schools implemented the program (n=241 students), with 27 comparison schools (n=251 students). Students reported smoking in the last 7 and 30 days at baseline and follow-up.

Diabetes self-management education program for Medicaid recipients: a continuous quality improvement process.

Purpose: Diabetes self-management education (DSME) is the cornerstone in effective management of diabetes. The continuous quality improvement process was used to identify the problem, collect and analyze data, and develop and implement a DSME program for Medicaid recipients, and subsequently, the program was evaluated to assess its effectiveness.

Methods: A DSME program consisting of a 1-hour initial assessment of individual needs followed by 12 hours of group education on nutrition and self-management was provided to 212 Arkansas Medicaid recipients over 1 year.

An approach to coordinate efforts to reduce the public health burden of stroke: the Delta States Stroke Consortium.

Stroke is the third leading cause of death and a leading cause of disability in the United States, with a particularly high burden on the residents of the southeastern states, a region dubbed the "Stroke Belt." These five states - Alabama, Arkansas, Louisiana, Mississippi, and Tennessee - have formed the Delta States Stroke Consortium to direct efforts to reduce this burden. The consortium is proposing an approach to identify domains where interventions may be instituted and an array of activities that can be implemented in each of the domains.

Policy and environmental indicators for heart disease and stroke prevention: data sources in two states.

Introduction: Investigators in South Carolina and Alabama assessed the availability of data for measuring 31 policy and environmental indicators for heart disease and stroke prevention. The indicators were intended to determine policy and environmental support for adopting heart disease and stroke prevention guidelines and selected risk factors in 4 settings: community, school, work site, and health care.

Methods: Research teams used literature searches and key informant interviews to explore the availability of data sources for each indicator.
