Occupational high-temperature exposure and biological aging in male workers
In an abstract comparing 140 heat-exposed and 207 non-exposed male workers, occupational high-temperature exposure was associated with greater biological age acceleration; an interaction with BMI was reported. [1]

Heat-exposed versus non-exposed male workers
The abstract describes a comparison of 140 male workers exposed to occupational high temperatures with 207 male non-exposed control workers. Questionnaire surveys and health examinations were conducted. Biological age and organ-specific biological age were calculated with the Klemera-Doubal method. The groups differed in length of service, systolic blood pressure, red blood cell count, albumin, urea, creatinine, biological age acceleration and liver-kidney biological age acceleration.

Biological age acceleration and BMI interaction
Generalized linear models were used to analyze effects of occupational high-temperature exposure, body mass index, smoking, alcohol consumption and sleep duration on biological age acceleration and organ-specific biological age. The abstract concludes that occupational high-temperature exposure may accelerate biological aging and reports an interaction between this exposure and BMI in relation to biological age acceleration. These are associations from an observational comparison, not evidence that heat exposure causes aging.

Abstract-only scope of the worker study
Only the abstract was reviewed; the full text was not reviewed. The abstract does not report follow-up duration, how exposure was quantified, or effect sizes and confidence intervals. Because the design is an observational comparison of exposed and non-exposed workers, the reported links cannot establish causation, and the findings concern measured biological age, not lifespan or clinical outcomes.

How to interpret this
Abstract only; the full text was not reviewed. Follow-up, exposure measurement details and effect estimates are not reported in the abstract, and the observational design cannot establish causation.
Based on the study abstract; the full paper, tables and supplementary data were not reviewed.
