The independent source for health policy research, polling, and news.
KFF’s policy research provides facts and analysis on a wide range of policy issues and public programs.
KFF designs, conducts and analyzes original public opinion and survey research on Americans’ attitudes, knowledge, and experiences with the health care system to help amplify the public’s voice in major national debates.
KFF Health News is a national newsroom that produces in-depth journalism about health issues and is one of the organization’s core operating programs.
This issue brief examines the most recent trends in children’s routine vaccinations, including COVID-19, and explores what to watch as children head back to school this year.
This brief examines the share of children with obesity, how obesity screening and treatment is covered under Medicaid for children, and what recent changes may mean for Medicaid programs and enrollees in the future.
Amid growing concerns about the mental health of children, about one in ten parents say their children are in fair or poor mental health. Rates of mental health treatment and access for children vary by factors such as race and ethnicity, as do experiences with unfair treatment or discrimination.
A new KFF analysis of provisional 2022 data from the Centers for Disease Control shows that the recent increases in firearm death rates among children and adolescents ages 17 and under were driven largely by gun assaults, which accounted for 66% of firearm deaths among young people in 2022, up from 54% in 2019.
This issue brief provides state level CHIP enrollment data, adding the June 2013 period. In June 2013, over 5.7 million children were enrolled in the Children’s Health Insurance Program (CHIP.) Enrollment in June 2013 increased by 190,453 or by 3.4 percent, compared to one year earlier. Since 2009, annual rates of growth have remained fairly steady, ranging between 3.2 percent and 3.8 percent. In contrast, during the height of the Great Recession, enrollment increased annually by 7.8 to 10 percent. Overall, CHIP enrollment continued to increase, but growth slow to the lowest rates since the start of the Recession as the economic conditions continued to improve. CHIP programs, along with state Medicaid programs continue to play a critical role in assuring health coverage for uninsured children.
This issue brief describes the role that Medicaid plays for children with special health care needs. It explains common eligibility pathways, covered services, and program spending for these children. The Appendix includes 50-state data on the number of children with special health care needs covered by Medicaid/CHIP. A companion brief compares key characteristics of Medicaid/CHIP children with special health care needs to those covered by private insurance.
The Children’s Health Insurance Program (CHIP) was established in 1997 to provide coverage for uninsured children who are low-income but above the threshold for Medicaid eligibility. In 2009, and again in the Affordable Care Act (ACA), Congress extended federal funding for CHIP, but funding will expire a little over a year from now. Decisions about CHIP’s future funding will be consequential as more than 8 million low-income children were covered by CHIP at some point during 2012. To help inform the policy debate about CHIP, this brief reviews key data and evidence from the large body of research on the impact of children’s coverage.
This volume explores findings from the KFF-Washington Post Survey of Parents on views of childhood vaccines; how ACIP may have contributed to concerns about hepatitis B and COVID-19 vaccines; recent HHS warnings about alleged links between Tylenol use in pregnancy and autism; and AI-generated deepfakes impersonating doctors to sell products.
Following the Trump administration’s warning last month that using acetaminophen – the active ingredient in Tylenol – during pregnancy can increase the risk of autism in children, very few adults say the claim about a causal relationship is “definitely true,” though much of the public is uncertain whether to believe it. Trust in the CDC to provide reliable vaccine information has fallen to a new low.
