Adult education

Q: What did studies of Adult education find?

Studies of Adult education measured 3 outcomes; the most studied are Association between childhood meat consumption and Mini-Mental State Examination score (1 study), hippocampal volume (1) and total brain volume (1).

Q: What is Adult education linked with?

Studies link Adult education with 2 measures, most often dementia (2 studies) and fluid intelligence score (1).

Adult education has been studied in 3 papers since 2023: 3 observational studies in people; 1 in the past year. The newest story, Oct 20, 2026: “Childhood meat intake linked to better late-life thinking”.

Childhood meat intake linked to better late-life thinking

Participants reporting almost daily childhood meat consumption scored 1.13 points higher on a later-life cognitive test than those reporting none or about once yearly.Participants reporting almost daily childhood meat consumption scored 1.13 points higher on a later-life cognitive test than those reporting none or about once yearly.
