To investigate mid-life employment trajectories in relation to later-life memory function and rate of decline in rural South Africa.

Data from the Agincourt Health and Socio-Demographic Surveillance System were linked to the ‘Health and Ageing in Africa: A Longitudinal Study of an INDEPTH Community in South Africa’ (HAALSI) in rural Agincourt, South Africa (N = 3133). Employment was assessed every 4 years over 2000–12 as being employed (0, 1, 2 and ≥3 time points), being employed in a higher-skill occupation (0, 1, 2 and ≥3 time points) and dynamic employment trajectories identified using sequence analysis. Latent memory z-scores were assessed over 2014–22. Mixed-effects linear regression models were fitted to examine the associations of interest.

Sustained mid-life employment from 2000–12 (β = 0.052, 95% CI: -0 …
