Safety restraint use linked to hospital use and charges in Arkansas.

Crash data from 2001-2005 was linked to hospital discharge data to determine the impact of safety restraint use on crashed-related hospital charges and use for 4013 hospitalizations. Safety restraint use, year of hospitalization and age group affected the hospital charges and length of stay after a crash. Mean hospital charges were 44% greater for unrestrained patients ($44,736 versus $30,990); mean length of stay was 23% longer for the unrestrained (9.2 days versus 7.5 days). Lack of safety restraint use was associated with greater use of hospital resources. Prevention efforts should focus on increasing compliance.

Impact of addition of philosophical exemptions on childhood immunization rates.

BACKGROUND: Although incidence of vaccine-preventable diseases has decreased, states' school immunization requirements are increasingly challenged. Subsequent to a federal court ruling affecting religious immunization exemptions to school requirements, new legislation made philosophical immunization exemptions available in Arkansas in 2003-2004. This retrospective study conducted in 2006 describes the impact of philosophical exemption legislation in Arkansas. METHODS: Arkansas Division of Health data on immunization exemptions granted were linked to Department of Education data for all school attendees (grades K through 12) during 2 school years before the legislation (2001-2002 and 2002-2003 [Years 1 and 2, respectively]) and 2 years after philosophical exemptions were available (2003-2004 and 2004-2005 [Years 3 and 4, respectively]). Changes in numbers, types, and geographic distribution of exemptions granted are described. RESULTS: The total number of exemptions granted increased by 23% (529 to 651) from Year 1 to 2; by 17% (total 764) from Year 2 to 3 after philosophical exemptions were allowed; and by another 50% from Year 3 to 4 (total 1145). Nonmedical exemptions accounted for 79% of exemptions granted in Years 1 and 2, 92% in Year 3, and 95% in Year 4. Importantly, nonmedical exemptions clustered geographically, suggesting concentrated risks for vaccine-preventable diseases in Arkansas communities. CONCLUSIONS: Legislation allowing philosophical exemptions from school immunization requirements was linked to increased numbers of parents claiming nonmedical exemptions, potentially causing an increase in risk for vaccine-preventable diseases. Continued education and dialogue are needed to explore the balance between individual rights and the public's health.

Lessons learned while implementing a legislated school policy: body mass index assessments among Arkansas's public school students.

BACKGROUND: To comprehensively address the childhood and adolescent obesity epidemic, Arkansas enacted Act 1220 of 2003. Among a series of community- and school-based interventions, the Act requires each public school student to have his/her body mass index (BMI) assessed and reported annually to parents. The process of implementing this policy on a statewide level and lessons learned are described in this article. METHODS: A confidential, standardized protocol to measure student BMIs and report results to parents was developed. Affordable, reliable, and durable equipment was selected and school personnel who conducted BMI assessments were trained to ensure standardization. To enhance the efficiency and ease of the measurement and reporting process and promote long-term and locally based sustainability, during the first 3 years of implementation, a transition from a paper-based system to a Web-based system was made. Confidential, individualized Child Health Reports have provided students' parents with information about the health of their children. RESULTS: Participation by schools and students has been high as a result of collaboration between the health and education communities and the students and their families. Childhood obesity has not increased since Act 1220 was passed into law. CONCLUSIONS: Parents, schools, school districts, and the state are able to better understand the obesity epidemic and track progress using detailed annual data. Providing a standardized measurement protocol, equipment, and efficient data entry and report generation options has enabled Arkansas to institutionalize the BMI assessment process in public schools.

Learning from state surveillance of childhood obesity.

Data on childhood obesity collected by the Centers for Disease Control and Prevention helped reveal the nation's epidemic of overweight and obese children. But more information is needed. Collecting body mass index (BMI)-the widely accepted measurement of childhood weight status-at the state and local levels can be instrumental in identifying and tracking obesity trends, designing interventions to help overweight children, and guiding broader policy solutions. Approximately thirty states have enacted or proposed BMI surveillance laws and regulations. Arkansas stands out as the state with the highest-quality surveillance data. Innovative strategies being pursued in a number of other states should be explored for broader dissemination.

Arkansas' experience: statewide surveillance and parental information on the child obesity epidemic.

Parents, clinicians, public health officials, and policy makers need readily available information on the extent of the childhood obesity epidemic. As in any epidemic, the strategies and tools used to combat the imminent threat are frequently based on scientific rationale and experience but applied in areas in which we lack complete understanding. The urgent need for information requires execution of decisions that are not risk-free--such is the case of BMI screening obesity. Use of BMI percentiles to classify weight status among youth and quantify the epidemic can inform and engage parents and other key stakeholders. Arkansas has completed its sixth year of BMI screenings for public school students. Through a groundbreaking legislative mandate that requires BMI assessments in public schools, the state has achieved both enhanced awareness among parents and their children and increased engagement by school, clinical, public health, and community leaders in response to the epidemic. External evaluations conducted since institution of BMI assessments have revealed none of the initially feared negative consequences of BMI measurements such as teasing, use of diet pills, or excessive concerns about weight. In the face of this epidemic, the risks of using BMI assessments in clinical or school-based settings must be recognized but can be managed. Arkansas' Act 1220 and BMI-reporting efforts have not only afforded parents detailed information about their children's health but also provided longitudinal data needed to fully understand the scope of childhood and adolescent obesity in the state and to track progress made in combating this epidemic.

Self-reported health risks linked to health plan cost and age group.

BACKGROUND: Studies of private sector employee populations have shown an association between health-risk factors and healthcare costs. Few studies have been conducted on large, public sector employee populations. The objective of the current study was to quantify health plan costs associated with individual tobacco, obesity, and physical inactivity risks in Arkansas's state employee plan. METHODS: De-identified medical and pharmacy claim costs incurred October 1, 2004-February 28, 2006 were linked with results from self-reported health-risk assessments (HRA) completed August 1, 2006-October 31, 2006. High- and no-risk groups were defined on the basis of cigarette use, BMI, and days/week of moderate physical activity. Annualized costs were compared between groups and across ages. Data were analyzed in September 2007. RESULTS: Of the eligible adults (n=77,774), 56% (n=43,461) voluntarily accessed and completed an Internet-based HRA and had claims data-linked for analyses. Average annual costs across the eligible population totaled $3205. Respondents with high risks incurred greater annual costs ($4432) than those with no risks ($2382). Costs were greater among those with one or more risks, compared with no risks, and increased with age. The greatest average annual cost was for people aged 55-64 years in the high-risk group, who had a 2.2-fold higher cost than those aged 55-64 years in the no-risk group ($7233 versus $3266). CONCLUSIONS: Healthcare costs increased with age and were differentially higher for those who used tobacco, were obese, or were physically inactive. The financial viability of the healthcare system is at risk, particularly in plans with a high proportion of adults with health-risk factors.

Poor performance of body mass index as a marker for hypercholesterolemia in children and adolescents.

OBJECTIVE: To evaluate the test performance of specific body mass index (BMI) percentile cutoffs for detecting children/adolescents with hypercholesterolemia. DESIGN: Cross-sectional analysis. SETTING: National Health and Nutrition Examination Survey 1999-2004. PARTICIPANTS: Population-based sample of children (aged 3-18 years) with nonfasting total cholesterol (TC) and high-density lipoprotein (HDL) cholesterol levels and adolescents (aged 12-18 years) with fasting low-density lipoprotein (LDL) cholesterol and triglyceride (TG) levels. MAIN OUTCOME MEASURES: Individuals were classified as having hypercholesterolemia if they had a TC level greater than 200 mg/dL, HDL cholesterol level less than 35 mg/dL, LDL cholesterol level greater than 130 mg/dL, or TG level greater than 150 mg/dL, and sensitivity, specificity, and likelihood ratios were calculated for specific BMI percentiles. Receiver operating characteristic curves were constructed and area under the curve (AUC) was calculated. RESULTS: Receiver operating characteristic curves using BMI percentiles to predict abnormal levels of TC and LDL cholesterol had AUC values (0.60 for TC level and 0.63 for LDL cholesterol level) that were less than the threshold of acceptable discrimination (between 0.7-0.8). Body mass index percentiles provided better discrimination for detecting children with abnormal HDL cholesterol and TG levels, with AUC values approaching levels of acceptable discrimination (0.69 and 0.72, respectively), although there are no specific guidelines regarding management of children with these abnormalities. CONCLUSIONS: According to the American Academy of Pediatrics guidelines, abnormal levels of LDL cholesterol are used to determine which children require nutritional and pharmacologic therapy. Because BMI percentiles did not adequately identify children and adolescents with abnormal TC and LDL cholesterol levels, the new recommendations for targeted screening of obese children and adolescents may require further consideration.

Arkansas fights fat: translating research into policy to combat childhood and adolescent obesity.

National recommendations to address the emerging obesity epidemic include increased awareness, individual interventions, and environmental changes. However, guidance for translating public health and clinical evidence into meaningful policies has been limited. Arkansas formulated and passed simple yet powerful legislation to combat childhood obesity through actions in public schools. Specific legislative requirements were straightforward. Importantly, the act included an independent mechanism to identify, examine, debate, and develop further action steps. Based on our experience, we present a framework for developing a cross-sector approach to translating science into policy and practice, and we offer this guide to other states facing similar health threats.
