Early-life healthcare access linked to longer lives in the US
Exposure to a county health department before birth or in early childhood was associated with 1–4 months longer lives than exposure at older ages.
Limit: Extended records substantially underreported deaths after 2005

US men and women recorded in the 1940 census and Social Security death records were studied in an observational analysis of early-life healthcare access. Researchers compared longevity among people exposed at different ages to a county health department opening in their birth county. These departments aimed to provide affordable healthcare in disadvantaged and underserved areas during the early 20th century.
Exposure before birth or in early childhood was associated with longer lives. The association was more concentrated among non-white people and those with less-educated parents. In the preferred analysis, which covered deaths from 1988 to 2005, exposure at ages 0–4 was associated with 0.9 months longer life. Estimates increased when researchers extended the years of death records included.
Why it matters
The authors argue that better conditions before birth and better early-life health contribute to education and economic prospects in adulthood, with potential implications for later-life longevity.
Caveats
The observational design cannot establish that department openings caused longer lives. The main death-record window may have missed later deaths, while extended records substantially underreported deaths after 2005.
