Prevalence of selected risk behaviors and chronic diseases and conditions-steps communities, United States, 2006-2007.

PROBLEM: At least one chronic disease or condition affects 45% of persons and account for seven of the 10 leading causes of death in the United States. Persons who suffer from chronic diseases and conditions, (e.g., obesity, diabetes, and asthma) experience limitations in function, health, activity, and work, affecting the quality of their lives as well as the lives of their family. Preventable health-risk factors (e.g., insufficient physical activity, poor nutrition, and tobacco use and exposure) contribute substantially to the development and severity of certain chronic diseases and conditions. REPORTING PERIOD COVERED: 2006-2007 DESCRIPTION OF THE SYSTEM: CDC's Healthy Communities Program funds communities to address chronic diseases and related risk factors through policy, systems, and environmental change strategies. As part of the Healthy Communities Program, 40 Steps communities were funded nationwide to address six focus areas: obesity, diabetes, asthma, physical inactivity, poor nutrition, and tobacco use and exposure. During 2006-2007, 38 and 39 of the 40 communities conducted a survey to collect adult health outcome data. The survey instrument was a modified version of the Behavioral Risk Factor Surveillance System (BRFSS) survey, a state-based, random-digit-dialed telephone survey. The survey instrument collected information on chronic diseases and conditions, health risk behaviors, and preventive health practices related to Steps community outcomes from noninstitutionalized community members aged ≥18 years. RESULTS: Prevalence estimates of chronic diseases and conditions and risk behaviors varied among Steps communities that reported data for 2006 and 2007. The proportion of the population that achieved Healthy People 2010 (HP 2010) objectives also varied among the communities. In 2006, the estimated prevalence of respondents aged ≥18 years being overweight or obese as calculated from self-reported weight and height ranged from 51.8% to 73.7%. The nationwide 2006 BRFSS median was 62.3%; a total of 20 communities exceeded this median. In 2007, the estimated prevalence being overweight or obese ranged from 50.5% to 77.2%. The nationwide 2007 BRFSS median was 63.0%; a total of 18 communities exceeded this median. In 2006, the estimated prevalence of diagnosed diabetes (excluding gestational diabetes) ranged from 3.7% to 19.7%. None of the communities achieved the HP 2010 objective of increasing to 91% the proportion of adults with diabetes who have at least an annual clinical foot examination. Six communities reached the HP 2010 objective of increasing to 76% the proportion of adults with diabetes who have an annual dilated eye examination; 20 communities reached the HP 2010 objective of increasing to 65% the proportion of adults who have a glycosylated hemoglobin measurement (A1c) at least once a year. In 2007, the estimated prevalence of diagnosed diabetes (excluding gestational diabetes) ranged from 4.4% to 17.9%. None of the communities achieved the HP 2010 objective of increasing to 91% the proportion of adults with diabetes who have at least an annual clinical foot examination, eight communities achieved the HP 2010 objective of increasing to 76% the proportion of adults with diabetes who have an annual dilated eye examination, and 16 communities achieved the HP 2010 objective of increasing to 65% the proportion of adults who have an A1c at least once a year. In 2006, the prevalence of reported asthma ranged from 6.5% to 18.9%. Among those who reported having asthma, the prevalence of having no symptoms of asthma during the preceding 30 days ranged from 11.5% to 29.5% for five communities with sufficient data for estimates. In 2007, the estimated prevalence of reported asthma ranged from 7.5% to 18.9%. Among those who reported having asthma, the prevalence of having no symptoms of asthma during the preceding 30 days ranged from 10.3% to 36.1% for 12 communities with sufficient data for estimates. In 2006, the prevalence of respondents who engaged in moderate physical activity for ≥30 minutes at least five times a week or who reported vigorous physical activity for ≥20 minutes at least three times a week ranged from 42.3% to 59.9%. The prevalence of consumption of fruits and vegetables at least five times/day ranged from 11.1% to 30.2%. In 2007, the prevalence of moderate or vigorous physical activity ranged from 40.6% to 69.8%; 25 communities reached the HP 2010 objective to increase the proportion of adults who engage in physical activity to 50%. The prevalence of consumption of fruits and vegetables ≥5 times/day ranged from 14.6% to 37.6%. In 2006, the estimated prevalence among respondents aged >18 years who reported having smoked >100 cigarettes in their lifetime and who were current smokers on every day or some days at the time of the survey ranged from 12.5% to 48.0%. Among smokers, the prevalence of having stopped smoking for ≥1 day because of trying to quit smoking during the previous 12 months ranged from 48.4% to 67.9% for 31 communities. No communities reached the HP 2010 target of increasing to 75% smoking cessation attempts by adult smokers. In 2007, the estimated prevalence of current smokers ranged from 11.2% to 33.7%. Two communities reached the HP 2010 objective to reduce the proportion of adults who smoke. Among smokers, the prevalence of having stopped smoking for ≥1 day because of trying to quit smoking during the preceding 12 months ranged from 50.8% to 69.6% for 26 communities. No communities reached the HP 2010 objective of increasing to 75% smoking cessation attempts by adult smokers. INTERPRETATION: The findings in this report indicate variations in health risk behaviors, chronic diseases and conditions, and use of preventive health screenings and health services among Steps communities. These findings underscore the continued need to evaluate prevention interventions at the community level and to design and implement policies to promote and encourage healthy behaviors. PUBLIC HEALTH ACTION: Steps BRFSS data monitored the prevalence of health behaviors, conditions, and use of preventive health services. CDC (at the national level), and Steps staff at state, local, and tribal levels can use BRFSS data to demonstrate accountability to stakeholders; monitor progress in meeting objectives; focus activities on policy, systems and environmental change strategies with the greatest promise of results; identify collaboration opportunities; and identify and disseminate successes and lessons learned.

Effects on violence of laws and policies facilitating the transfer of youth from the juvenile to the adult justice system: a report on recommendations of the Task Force on Community Preventive Services.

The independent, nonfederal Task Force on Community Preventive Services (Task Force), which directs the development of the Guide to Community Preventive Services (Community Guide), conducted a systematic review of published scientific evidence concerning the effectiveness of laws and policies that facilitate the transfer of juveniles to the adult criminal justice system to determine whether these transfers prevent or reduce violence among youth who have been transferred and among the juvenile population as a whole. For this review, transfer is defined as placing juveniles aged <18 years under the jurisdiction of the adult criminal justice system. The review followed Community Guide methods for conducting a systematic review of literature and for providing recommendations to public health decision makers. Available evidence indicates that transfer to the adult criminal justice system typically increases rather than decreases rates of violence among transferred youth. Available evidence was insufficient to determine the effect of transfer laws and policies on levels of violent crime in the overall juvenile population. On the basis of these findings, the Task Force recommends against laws or policies facilitating the transfer of juveniles to the adult criminal justice system for the purpose of reducing violence.

Effectiveness of universal school-based programs to prevent violent and aggressive behavior: a systematic review.

Universal, school-based programs, intended to prevent violent behavior, have been used at all grade levels from pre-kindergarten through high school. These programs may be targeted to schools in a high-risk area-defined by low socioeconomic status or high crime rate-and to selected grades as well. All children in those grades receive the programs in their own classrooms, not in special pull-out sessions. According to the criteria of the systematic review methods developed for the Guide to Community Preventive Services (Community Guide), there is strong evidence that universal, school-based programs decrease rates of violence among school-aged children and youth. Program effects were consistent at all grade levels. An independent, recently updated meta-analysis of school-based programs confirms and supplements the Community Guide findings.

The effectiveness of universal school-based programs for the prevention of violent and aggressive behavior: a report on recommendations of the Task Force on Community Preventive Services.

Universal school-based programs to reduce or prevent violent behavior are delivered to all children in classrooms in a grade or in a school. Similarly, programs targeted to schools in high-risk areas (defined by low socioeconomic status or high crime rates) are delivered to all children in a grade or school in those high-risk areas. During 2004-2006, the Task Force on Community Preventive Services (Task Force) conducted a systematic review of published scientific evidence concerning the effectiveness of these programs. The results of this review provide strong evidence that universal school-based programs decrease rates of violence and aggressive behavior among school-aged children. Program effects were demonstrated at all grade levels. An independent meta-analysis of school-based programs confirmed and supplemented these findings. On the basis of strong evidence of effectiveness, the Task Force recommends the use of universal school-based programs to prevent or reduce violent behavior.

Effects on violence of laws and policies facilitating the transfer of juveniles from the juvenile justice system to the adult justice system: a systematic review.

The independent, nonfederal Task Force on Community Preventive Services (Task Force), which directs development of the Guide to Community Preventive Services (Community Guide), has conducted a systematic review of published scientific evidence concerning the effectiveness of laws and policies that facilitate the transfer of juveniles to the adult criminal justice system, on either preventing or reducing violence (1) among those youth who experience the adult criminal system or (2) in the juvenile population as a whole. This review focuses on interpersonal violence. Violence may lead to the juvenile's initial arrest and entry into the justice system and, for those who are arrested, may be committed subsequent to exiting the justice system. Here transfer is defined as the placement of juveniles aged less than 18 years under the jurisdiction of the adult criminal justice system, rather than the juvenile justice system, following arrest. Using the methods developed by the Community Guide to conduct a systematic review of literature and provide recommendations to public health decision makers, the review team found that transferring juveniles to the adult justice system generally increases, rather than decreases, rates of violence among transferred youth. Evidence was insufficient for the Task Force on Community Preventive Services to determine the effect of such laws and policies in reducing violent behavior in the overall juvenile population. Overall, the Task Force recommends against laws or policies facilitating the transfer of juveniles from the juvenile to the adult judicial system for the purpose of reducing violence.

Public health strategies for preventing and controlling overweight and obesity in school and worksite settings: a report on recommendations of the Task Force on Community Preventive Services.

Reducing morbidity and mortality related to overweight and obesity is a public health priority. Various interventions in school and worksite settings aim to maintain or achieve healthy weight. To identify effective strategies for weight control that can be implemented in these settings, the Task Force on Community Preventive Services (Task Force) has conducted systematic reviews of the evidence on nutrition, physical activity, combinations of these interventions, and other behavioral interventions (e.g., cognitive techniques such as self-awareness and cue recognition). Task Force recommendations are based on evidence of effectiveness, which is defined in this report as achieving a mean weight loss of > or =4 pounds, measured > or =6 months after initiation of the intervention program. The Task Force recommends multicomponent interventions that include nutrition and physical activity (including strategies such as providing nutrition education or dietary prescription, physical activity prescription or group activity, and behavioral skills development and training) to control overweight and obesity among adults in worksite settings. The Task Force determined that insufficient evidence existed to determine the effectiveness of combination nutrition and physical activity interventions to prevent or reduce overweight and obesity in school settings because of the limited number of qualifying studies reporting noncomparable outcomes. This report describes the methods used in these systematic reviews; provides additional information regarding these recommendations; and cites sources for full reviews containing details regarding applicability, other benefits and harms, barriers to implementation, research gaps, and economic data (when available) regarding interventions.
