Early Release

  • Blood Lead Levels Among Children Aged <6 Years — Flint, Michigan, 2013–2016

    June 24, 2016
    During April 25, 2014–October 15, 2015, approximately 99,000 residents of Flint, Michigan, were affected by changes in drinking water quality after their water source was switched from the Detroit Water Authority (DWA), sourced from Lake Huron, to the Flint Water System (FWS), sourced from the Flint River. Studies conducted by local and national investigators detected an increase in the prevalence of blood lead levels (BLLs) ≥5 µg/dL (the CDC reference level) among children aged <5 years living in Flint and an increase in water lead levels after the water source switch. To assess the impact on BLLs of consuming contaminated drinking water, CDC examined the distribution of BLLs ≥5 µg/dL among children aged <6 years before, during, and after the switch in water source.

    Awareness of human immunodeficiency virus (HIV) infection through testing is the first step to prevention, health care, and social services that improve quality of life and length of survival. National HIV Testing Day, held annually on June 27, highlights the importance of HIV testing.

  • Health Care Use and HIV Testing of Males Aged 15–39 Years in Physicians’ Offices — United States, 2009–2012

    Eighty-one percent of new human immunodeficiency virus (HIV) infection diagnoses in the United States in 2014 were in males, with the highest number of cases among those aged 20–29 years. CDC analyzed data from the 2009–2012 National Ambulatory Medical Care Survey and U.S. Census data to estimate rates of health care use at U.S. physicians’ offices and HIV testing at these encounters. The study found males aged 15–39 years had an average of 1.35 visits to physicians’ offices each year. Less than 1.1% of the visits by males included an HIV test.


Surveillance Summaries

  • Youth Risk Behavior Surveillance — United States, 2015

    June 10, 2016
    Priority health-risk behaviors contribute to the leading causes of morbidity and mortality among youth and adults. The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority health behaviors among youth and young adults: 1) behaviors that contribute to unintentional injuries and violence; 2) tobacco use; 3) alcohol and other drug use; 4) sexual behaviors related to unintended pregnancy and sexually transmitted infections (STIs), including human immunodeficiency virus (HIV) infection; 5) unhealthy dietary behaviors; and 6) physical inactivity. Many high school students engage in behaviors that place them at risk for the leading causes of morbidity and mortality. YRBSS data are used widely to compare the prevalence of health behaviors among subpopulations of students; assess trends in health behaviors over time; monitor progress toward achieving 21 national health objectives for Healthy People 2020 and one of the 26 leading health indicators; provide comparable state and large urban school district data; and help develop and evaluate school and community policies, programs, and practices designed to decrease health-risk behaviors and improve health outcomes among youth.

Recommendations and Reports


  • Development of the Community Health Improvement Navigator Database of Interventions

    FEBRUARY 26, 2016
    This report describes the development of the database of interventions included in the Community Health Improvement Navigator, released by CDC in 2015. The database allows the user to easily search for multisector, collaborative, evidence-based interventions to address the underlying causes of the greatest morbidity and mortality in the United States: tobacco use and exposure, physical inactivity, unhealthy diet, high cholesterol, high blood pressure, diabetes, and obesity. Hospital administrators can use the CHI Navigator’s database of interventions to select and implement evidence-based interventions that have been effective in similar communities with similar collaborators to develop plans to address problems identified in the triennial community health needs assessment, in alignment with the IRS requirements for tax-exempt status.
