As a group, persons with disabilities show disparities in measures of overall health when compared with the general population. Much of this can be attributed to secondary conditions rather than to the impairment itself. Persons with disabilities can prevent and manage many of the conditions that contribute to these disparities. The Living Well with a Disability program was developed to support persons with disabilities to manage their health. The curriculum helps participants achieve early success in self-management of quality-of-life goals to build confidence for making health behavior changes; it includes 11 chapters that facilitators use to conduct an orientation session and 10 weekly, 2-hour sessions. The program has been implemented by 279 community-based agencies in 46 states. On the basis of the data from the field trial, these community applications have served approximately 8,900 persons since 1995, resulting in an estimated savings of $6.4-$28.8 million for health care payers. Persons with disabilities have unique needs that can be addressed through multiple levels of intervention to reduce health disparities. The Living Well with a Disability program is a promising intervention that has demonstrated improvements in health-related quality of life and health care use.","PeriodicalId":37858,"journal":{"name":"MMWR supplements","volume":"62 1","pages":"61-7"},"PeriodicalIF":0.0,"publicationDate":"2016-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73830616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite strong evidence of their effectiveness, CRC screening tests are underused. Racial/ethnic minority groups, persons without insurance, those with lower educational attainment, and those with lower household income levels have lower rates of CRC screening. Since 2009, CDC's Colorectal Cancer Control Program (CRCCP) has supported state health departments and tribal organizations in implementing evidence-based interventions (EBIs) to increase use of CRC screening tests among their populations. This report highlights the successful implementation of EBIs to address disparities by two CRCCP grantees: the Alaska Native Tribal Health Consortium (ANTHC) and Washington State's Breast, Cervical, and Colon Health Program (BCCHP). ANTHC partnered with regional tribal health organizations in the Alaska Tribal Health System to implement provider and client reminders and use patient navigators to increase CRC screening rates among Alaska Native populations. BCCHP identified patient care coordinators in each clinic who coordinated staff training on CRC screening and integrated client and provider reminder systems. In both the Alaska and Washington programs, instituting provider reminder systems, client reminder systems, or both was facilitated by use of electronic health record systems. Using multicomponent interventions in a single clinical site or facility can support more organized screening programs and potentially result in greater increases in screening rates than relying on a single strategy. Organized screening systems have an explicit policy for screening, a defined target population, a team responsible for implementation of the screening program, and a quality assurance structure. Although CRC screening rates in the United States have increased steadily over the past decade, this increase has not been seen equally across all populations. Increasing the use of EBIs, such as those described in this report, in health care clinics and systems that serve populations with lower CRC screening rates could substantially increase CRC screening rates.","PeriodicalId":37858,"journal":{"name":"MMWR supplements","volume":"214 1","pages":"21-8"},"PeriodicalIF":0.0,"publicationDate":"2016-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89180785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Achieving community-wide reductions in youth violence and health disparities has been limited in part because of the lack of prevention strategies to address community risk factors. CDC-supported research has resulted in three promising community-level approaches: Business Improvement Districts (BIDs) in Los Angeles, California; alcohol policy to reduce youth access in Richmond, Virginia; and the Safe Streets program in Baltimore, Maryland. Evaluation findings indicated that BIDs in Los Angeles were associated with a 12% reduction in robberies (one type of violent crime) and an 8% reduction in violent crime overall. In Richmond's alcohol policy program, investigators found that the monthly average of ambulance pickups for violent injuries among youth aged 15-24 years had a significantly greater decrease in the intervention (19.6 to 0 per 1,000) than comparison communities (7.4 to 3.3 per 1,000). Investigators of Safe Streets found that some intervention communities experienced reductions in homicide and/or nonfatal shootings, but results were not consistent across communities. Communitywide rates of violence can be changed in communities with disproportionately high rates of youth violence associated with entrenched health disparities and socioeconomic disadvantage. Community-level strategies are a critical part of comprehensive approaches necessary to achieve broad reductions in violence and health disparities.","PeriodicalId":37858,"journal":{"name":"MMWR supplements","volume":"159 1","pages":"57-60"},"PeriodicalIF":0.0,"publicationDate":"2016-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77145908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This report examined health disparities in the United States associated with various characteristics, including race/ethnicity, sex, income, education, disability status, and geography. Health disparities were defined as \"differences in health outcomes and their determinants between segments of the population, as defined by social, demographic, environmental, and geographic attributes\". Among other recommendations, the 2011 CHDIR emphasized the need to address health disparities with a dual intervention strategy focused on populations at greatest need and on improving the health of the U.S. population by making interventions available to everyone. The 2013 CHDIR updated the 2011 CHDIR and included additional reports on social and environmental determinants of health; the supplement emphasized the importance of multisectoral collaboration, highlighting the need for a comprehensive, community-driven approach to reducing health disparities in the United States. A follow-up report described five interventions that were shown to be effective or demonstrated promise for reducing health disparities. These publications have focused attention on the need to address health disparities in the United States, as well as on programs and interventions that address them. This supplement describes additional interventions that address particular disparities observed by race and ethnicity, socioeconomic status, geographic location, disability, and/or sexual orientation across a range of conditions, including asthma, infection with HIV and hepatitis A, use of colorectal cancer screening, youth violence, food security, and health-related quality of life.","PeriodicalId":37858,"journal":{"name":"MMWR supplements","volume":"1 1","pages":"2-3"},"PeriodicalIF":0.0,"publicationDate":"2016-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87090445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During 1996-2006, the Advisory Committee on Immunization Practices (ACIP) made incremental changes in hepatitis A (HepA) vaccination recommendations to increase coverage for children and persons at high risk for HAV infection. This report examines the temporal association of ACIP-recommended HepA vaccination and disparities (on the absolute scale) in cases of HAV disease and on seroprevalence of HAV-related protection (measured as antibody to HAV [anti-HAV]). ACIP-recommended childhood HepA vaccination in the United States has eliminated most absolute disparities in HAV disease by age, race/ethnicity, and geographic area with relatively modest ≥1-dose and ≥2-dose vaccine coverage. However, the increasing proportion of cases of HAV disease among adults with identified and unidentified sources of exposure underscores the importance of considering new strategies for preventing HAV infection among U.S. adults. For continued progress to be made toward elimination of HAV disease in the United States, additional strategies are needed to prevent HAV infection among an emerging population of susceptible adults. Notably, HAV infection remains endemic in much of the world, contributing to U.S. cases through international travel and the global food economy.","PeriodicalId":37858,"journal":{"name":"MMWR supplements","volume":"69 1","pages":"29-41"},"PeriodicalIF":0.0,"publicationDate":"2016-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78646333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CDC has funded research to adapt and demonstrate the efficacy of Personalized Cognitive Counseling (PCC) as an HIV prevention intervention. Project ECHO, based in San Francisco, California, during 2010-2012, involved an adaptation of PCC for HIV-negative episodic substance-using men who have sex with men (SUMSM) and a randomized trial to test its efficacy in reducing sexual and substance-use risk behaviors. Episodic substance use is the use of substances recreationally and less than weekly. PCC is a 30-minute to 50-minute counseling session that involves addressing self-justifications men use for engaging in risky sexual behavior despite knowing the potential for HIV infection. By exploring these justifications, participants become aware of the ways they make sexual decisions, become better prepared to realistically assess their risk for HIV during future risky situations, and make decisions to decrease their HIV risk. The findings of Project ECHO demonstrated the efficacy of PCC for reducing HIV-related substance-use risk behaviors. The study also demonstrated efficacy of PCC for reducing sexual risk behaviors among SUMSM screened as nondependent on targeted drug substances. CDC has identified PCC as a \"best evidence\" HIV behavioral intervention and supports its national dissemination. Several features of PCC enhance its feasibility of implementation: it is brief, delivered with HIV testing, relatively inexpensive, allows flexibility in counselor qualifications and delivery settings, and is individualized to each client. The original PCC and its adapted versions can contribute to reducing HIV-related health disparities among high-risk MSM, including substance users, by raising awareness of and promoting reductions in personal risk behaviors.","PeriodicalId":37858,"journal":{"name":"MMWR supplements","volume":"46 1","pages":"42-50"},"PeriodicalIF":0.0,"publicationDate":"2016-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76281843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Atlanta, GA: US Department of Health and Human Services, CDC; 2015). The intervention has been implemented elsewhere, enhanced, and further evaluated in longitudinal intervention and implementation studies.
