  • Excessive alcohol use is a leading cause of preventable death in the United States and is associated with various health problems, including cancer, heart disease, and poor mental health.
  • It is responsible for more than 95,000 deaths in the US each year, resulting in 2.8 million years of potential life lost and shortening the lifespan by an average of 29 years.

  • CDC’s newly released Youth Risk Behavior Survey Data Summary & Trends Report: 2009–2019[PDF – 30.5MB], provides an in-depth look at 10 years of trends in health behaviors and experiences among US high school students, including sexual behavior, high-risk substance use, mental health, experience of violence, and suicide.
  • This report revealed concerning trends about the mental health of high school students—for example, more than 1 in 3 students reported persistent feelings of sadness or hopelessness in 2019, a 40% increase since 2009.
  • To promote good adolescent mental health, public health agencies, schools, and communities can provide youth-friendly mental health services and build supportive environments that provide a sense of safety and connection for all students.

  • Every year, 700 women die in the United States from problems related to pregnancy or delivery complications, but two-thirds of these deaths are preventable. Recognizing urgent warning signs during and after pregnancy and getting immediate care can save lives.
  • CDC’s Hear Her campaign encourages partners, friends, and family to really listen and take action when a pregnant or postpartum woman says something doesn’t feel right.
  • Public health professionals can help prevent pregnancy-related deaths by using and sharing these personal stories and Hear Her campaign resources, including graphics, videos, social media posts, and PSAs.

  • CDC’s 2019 Youth Risk Behavior Survey (YRBS) provides a pre-COVID-19 snapshot of the health of nearly 14,000 American students; these results can serve as a baseline to understand the pandemic’s potential impact on student health behaviors and experiences.
  • The 2019 YRBS results show that many student health behaviors were moving in the right direction before the pandemic, including not having sex, using illicit drugs, and consuming soda. However, behaviors related to experiences of violence, poor mental health, and unhealthy diet show more action is needed to help students achieve good physical and mental health.
  • Health agencies, schools, and communities can use CDC’s YRBS data, programs, and resources to help adolescents avoid health risks and begin to recover from the effects of the pandemic.

  • Excessive alcohol use is a leading cause of preventable death in the United States and is associated with various health problems, including cancer, heart disease, and poor mental health.

  • Acute flaccid myelitis (AFM) is an uncommon but life-threatening neurologic condition that affects mostly children and can lead to permanent paralysis. The most common symptom of AFM is limb weakness.
  • AFM is a medical emergency. In 2018, most patients with AFM were hospitalized, and 1 in 4 hospitalized patients required a ventilator—according to CDC’s latest Vital Signs report.
  • Pediatricians and medical providers in emergency departments and urgent care centers should be prepared to quickly recognize the symptoms of AFM and immediately hospitalize affected patients.

  • Contact tracing—or reaching out to people who have an infectious disease, and those they came in contact with, to help them take care of themselves and protect others—is critical to slowing the spread of COVID-19.
  • Successful contract tracing requires staff with training and access to social and medical support systems that can help patients and contacts.
  • Health departments can use CDC’s COVID-19 Contact Tracing Communication Toolkit to spread the word about the importance of contact tracing and how we can work together to stop COVID-19.

  • HIV can affect anyone, regardless of sexual orientation, race, ethnicity, gender, or age, but certain groups are at higher risk.
  • To help people estimate their individual risk of getting or transmitting HIV, CDC has released the HIV Risk Reduction Tool, a customizable online tool that shows users how to lower their risk of HIV and find nearby testing and preventive services.
  • Health professionals can promote the tool and encourage people to learn about the HIV risk of different sexual behaviors and how various risk and protective factors can change that risk.

  • More than 93 million American adults are at high risk for vision loss, and 40% of them did not receive an eye exam in the past year, according to a recent CDC study.
  • Vision problems can be worsened by chronic conditions, such as diabetes, but vision health is rarely incorporated into chronic disease prevention and management programs.
  • Public health agencies and their partners can guide their vision loss prevention programs with CDC’s Vision Health Initiative resources that include a new vision and eye health toolkit.

  • According to a recent CDC study, people with one or more chronic health conditions were more likely to report more frequent or worsening memory problems, also called subjective cognitive decline.
  • One in 9 women aged 45 years or older report subjective cognitive decline; 83% of women with subjective cognitive decline have at least one chronic condition.
  • Healthcare providers should work with their patients, especially those 45 years or older with chronic conditions, to implement 8 steps for a healthy body and healthier brain.

  • Progress has stalled in controlling foodborne pathogens in the United States, according to a new report from CDC’s Foodborne Diseases Active Surveillance Network.
  • New lab technologies have enhanced our capabilities for diagnostics and surveillance of foodborne diseases, but targeted interventions are needed to reduce foodborne illnesses.
  • Health departments can culture specimens with positive culture-independent diagnostic test results to help better identify antibiotic resistance, find outbreaks, monitor disease trends, and inform policy and prevention efforts.

  • One in 54 children were identified with autism in 2016, based on data collected on 8-year-old children across 11 US communities.
  • Early detection of autism is improving: the percentage of 4-year-old children with autism who received their first developmental evaluation by age 36 months increased from 74% in 2014 to 84% in 2016.
  • Healthcare providers can implement CDC’s Learn the Signs. Act Early. program to increase developmental screening and surveillance and help identify children with developmental disabilities earlier to allow for early intervention.

  • People with diabetes are more than twice as likely to develop chronic kidney disease (CKD) than those who don’t have diabetes—about 1 in 3 adults with diabetes may have CKD.
  • Many people don’t know they have CKD until the disease is advanced and they need dialysis or a kidney transplant to survive.
  • Healthcare professionals can ensure their patients with diabetes are tested for CKD and help them understand how to prevent or delay the disease.

  • The 500 Cities Project provides small-area data estimates on risk behaviors, health outcomes, and use of preventive services for the most common, costly, and preventable chronic diseases.
  • CDC released updated city and census tract-level estimates for 20 of the 27 measures for the 500 Cities Project.
  • Health professionals can view data by city or census tract, explore the interactive map, compare cities, and download data to identify emerging health problems and plan effective interventions.
