Julia Clifford Lathrop was an activist and social reformer in the late nineteenth to early twentieth centuries and the first chief of the United States Children’s Bureau. In that capacity, she conducted demographic studies to identify links between socioeconomic factors and infant mortality rates. Lathrop mobilized the effort to increase birth registration and designed programs and publications to promote infant and maternal health throughout the US. Through her studies, she empirically linked poverty and lack of education with higher than normal risks of infant and maternal mortality, and her results supported legislation aimed at lowering infant and maternal mortality in the US.

In November 1921, US Congress passed the National Maternity and Infancy Protection Act, also called the Sheppard-Towner Act. The Act provided federal funds to states to establish programs to educate people about prenatal health and infant welfare. Advocates argued that it would curb the high infant mortality rate in the US. Many states accepted funding through the Sheppard-Towner Act, leading to the establishment of nearly 3,000 prenatal care clinics, 180,000 infant care seminars, over three million home visits by traveling nurses, and a national distribution of educational literature between 1921 and 1928. The Act provided funding for five years, but was repealed in 1929 after Congress did not renew it. Historians note that infant mortality did decrease during the years the Act was in effect. The Act also influenced provisions aimed at infant and maternity welfare in later legislation, such as the Social Security Act of 1935.

Prenatal Care is an educational booklet written by Mary Mills West of the US Children’s Bureau and published by the US Government Printing Office in 1913. The Bureau distributed West’s booklets in response to their field studies on infant mortality, which found that lack of access to accurate health and hygiene information put women and infants at greater than normal risk of death or disease. In Prenatal Care, West offers advice on nutrition, exercise, and personal hygiene during pregnancy and describes the processes of labor and birth. Soon after publication, women all over the US requested copies of Prenatal Care. Millions of copies of Prenatal Care were distributed nationally between 1921 and 1928 as part of educational programs funded by the Sheppard-Towner Act, and the infant mortality rate declined during that period.
