In 1976, the US Congress passed the Hyde Amendment, which banned the use of federal funding to pay for abortions through Medicaid. In 1976, Illinois Congressman Henry J. Hyde proposed the amendment to the Departments of Labor and Health, Education, and Welfare, Appropriation Act of 1977. In 1980, the US Supreme Court in Harris v. McRae (1980) upheld the constitutionality of the Hyde Amendment. Included annually in every Congressional appropriation act after the one passed in 1976, amended versions of the Hyde Amendment have restricted federal funding of abortion services for women participating in Medicaid.

On 30 June 1980, in a five to four decision, the US Supreme Court ruled in the Case Harris v. McRae that the Hyde Amendment of 1976 did not violate the US Constitution. The Hyde Amendment banned the use of federal funding to pay for any abortion services. The US Supreme Court's decision in Harris v. McRae overturned the decision of McRae v. Califano (1980), in which the US District Court for the Eastern District of New York had ruled that the funding restrictions established by the Hyde Amendment violated the US Constitution. After the US Supreme Court's ruling in Harris v. McRae, the Hyde Amendment continued to prohibit federal Medicaid funding for abortion services, limiting the funds available for low-income women seeking abortions.

In the 2012 case Texas Medical Providers Performing Abortion Services v. David Lakey, a US appeals court ruled as constitutional a Texas law that required abortion providers in the state to show women receiving abortions the ultrasound images of their fetuses. The law also required providers to describe the sounds of the fetuses' nascent hearts. In doing so, the court set precedent that ultrasound readings are necessary medical information for pregnant women seeking abortions, increasing the wait-period for women seeking abortions. The decision fueled debates in the early twenty-first century US abouts women's rights to abortions.

Dorothy Andersen studied cystic fibrosis in the United States during the early 1900s. In 1935, Andersen discovered lesions in the pancreas of an infant during an autopsy, which led her to classify a condition she named cystic fibrosis of the pancreas. In 1938, Andersen became the first to thoroughly describe symptoms of the medical condition cystic fibrosis. Commonly mistaken for celiac disease prior to the 1900s, Andersen defined cystic fibrosis as the build-up of pancreatic fluid in the body caused by the blockage of pancreatic ducts, and she determined that the two conditions were symptomatically different. Andersen developed an early method for diagnosing cystic fibrosis. By conceptualizing cystic fibrosis and defining its symptoms, Andersen laid the foundation for treatments that enabled infants diagnosed with the disease to survive into adulthood.

Better babies contests were competitions held in state fairs throughout the US during the early twentieth century in which babies between the ages of 6 and 48 months were judged for their health. In 1908, social activist Mary de Garmo established and held the first better babies contest at the Louisiana State Fair in Shreveport, Louisiana. The contests, mirroring theories established in the US’s eugenics movement of the twentieth century, aimed to establish standards for judging infant health. Nurses and physicians judged infants participating in the contest on mental health, physical health, and physical appearance. In 1913, the Woman’s Home Companion (WHC) magazine cosponsored de Garmo’s better babies contests and introduced the competition to state fairs throughout the US. Better babies contests helped promote routine health assessments of children by medical professionals.

In the 2014 case Burwell v. Hobby Lobby, the US Supreme Court ruled that the contraceptive mandate promulgated under the Patient Protection and Affordable Care Act violated privately held, for-profit corporations’ right to religious freedom. The contraception mandate, issued in 2012 by the US Department of Health and Human Services, required that employer-provided health insurance plans offer their beneficiaries certain contraceptive methods free of charge. In a five to four decision, the US Supreme Court maintained that the mandate, in cases of privately held, for-profit organizations like Hobby Lobby Inc., violated the Religious Freedom Restoration Act of 1993. Although the Court did not decide on the constitutionality of the mandate, their ruling enabled privately held, for-profit corporations that objected to the contraceptive mandate on religious grounds to be exempt from it.

In 2010, US Congress enacted section 3509 of the Patient Protection and Affordable Care Act or ACA, to target issues relating to women’s health. The ACA, signed into law by US President Barack Obama, aimed to increase people’s access to high-quality healthcare in the United States. Section 3509, titled “Improving Women’s Health,” established the Office on Women’s Health within the US Department of Health and Human Services and in four of its agencies, the Agency for Healthcare Research and Quality, the Center for Disease Control and Prevention, the Food and Drug Administration, and the Health Resources and Services Administration. Section 3509 of the ACA exemplified a federal effort to improve women’s health in the US by increasing the amount of research and programs focused on the health concerns of American women.
