Trends in healthy working life expectancy and its difference by workload group among aged over 50 years: a longitudinal perspective.
Article in Scandinavian journal of work, environment & health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesWhile extending working life is a key policy objective, its impact on population health is not fully understood. This study investigated the long-term effects of physical and psychological workloads as well as initial health-work status on healthy working life expectancy (HWLE), working life expectancy (WLE), and total life expectancy (TLE) at age 50.
methodsData were drawn from the Health and Retirement Study covering 1992-2022. The study population consisted of US adults aged ≥50 years. We implemented a multi-state life table approach based on continuous-time Markov models. Transition intensities between health and employment states were modeled to derive HWLE. Analyses were stratified by physical and psychological workload levels across three temporal cohorts.
resultsOver the study period, WLE increased significantly for both sexes, while TLE slightly declined. Conversely, HWLE decreased substantially across all groups and health states. Individuals in high physical workload groups experienced shorter WLE and HWLE compared to low workload groups. High psychological load was associated with a lower proportion of healthy working years, particularly among those with initial health limitations.
conclusionsThe extension of working lives is occurring at the cost of healthy years. Physical and psychological workloads exert distinct but equally detrimental effects on the sustainability of a healthy working life. These findings underscore the urgent need for targeted workplace interventions to protect worker health, particularly for vulnerable groups in high-stress or physically demanding jobs.
