Abstract

Objective Health effects of different physical activity domains (ie, during leisure time, work and transport) are generally considered positive. Using Active Worker consortium data, we assessed independent associations of occupational and leisure-time physical activity (OPA and LTPA) with all-cause mortality.

Design Two-stage individual participant data meta-analysis.

Data source Published and unpublished cohort study data.

Eligibility criteria Working participants aged 18–65 years.

Methods After data harmonisation, we assessed associations of OPA and LTPA with all-cause mortality. In stage 1, we analysed data from each study separately using Cox survival regression, and in stage 2, we pooled individual study findings with random-effects modelling.

Results In 22 studies with up to 590 497 participants from 11 countries, during a mean follow-up of 23.1 (SD: 6.8) years, 99 743 (16%) participants died. Adjusted for LTPA, body mass index, age, smoking and education level, summary (ie, stage 2) hazard ration (HRs) and 95% confidence interval (95% CI) for low, moderate and high OPA among men (n=2 96 134) were 1.01 (0.99 to 1.03), 1.05 (1.01 to 1.10) and 1.12 (1.03 to 1.23), respectively. For women (n=2 94 364), HRs (95% CI) were 0.98 (0.92 to 1.04), 0.96 (0.92 to 1.00) and 0.97 (0.86 to 1.10), respectively. In contrast, higher levels of LTPA were inversely associated with mortality for both genders. For example, for women HR for low, moderate and high compared with sedentary LTPA were 0.85 (0.81 to 0.89), 0.78 (0.74 to 0.81) and 0.75 (0.65 to 0.88), respectively. Effects were attenuated when adjusting for income (although data on income were available from only 9 and 6 studies, for men and women, respectively).

Conclusion Our findings indicate that OPA may not result in the same beneficial health effects as LTPA.

  • Contributors The ‘Active Worker core team’ (authors PC, MH, AH, RPT, PJM, SK, EC, WvM and AJvdB) developed the project’s protocol, including the analysis plan. PC conducted the analyses with the help of BC, while consulting NK and JT. All other authors (DDB, MA, LLK, AS, LBA, JK, AV, RP, ES, UG, AP, BT, AR, LB, KS, KF, MR-B, LL-B, AK, LA, MB, TI, AK, LH, MW, MB, JLM, PS, BGN, KED, UE, JC, MTJ, CBP) contributed by either providing their individual participant data or analysing their data remotely using our analysis plan. AJvdB Is the study guarantor. All authors reviewed the manuscript for important intellectual content.

  • Funding The Active Worker study was funded by The Netherlands Organisation for Health Research and Development; ZonMw (grant number: 531-00141-3). Funding for the SHIP study has been provided by the Federal Ministry for Education and Research (BMBF; identification codes 01 ZZ96030, 1 ZZ0103, 01 ZZ0701). The CARLA study was founded by a grant from the Deutsche Forschungsgemeinschaft (DFG) as part of the Collaborative Research Centre 598 ‘Heart failure in the elderly—cellular mechanisms and therapy’, by an additional single funding grant from the DFG, by three grants of the Wilhelm-Roux-Programme of the Martin-Luther-University of Halle-Wittenberg (FKZ 14/41, 16/19 and 28/21), by the Federal Employment Office, by the Ministry of Education and Cultural Affairs of Saxony-Anhalt (MK-CARLA-MLU-2011) and by the Ministry of Economics, Science and Digitization of Saxony-Anhalt via the EU European Regional Development Fund (ERDF), 'Autonomy in Old Age', BIOSALSA. The Primary Prevention study received support from the Swedish Research Council [2018-02527, 2019-00193]. The MONICA/KORA Augsburg study was initiated and financed by the Helmholtz Zentrum München—German Research Center for Environmental Health, which is funded by the German Federal Ministry of Education and Research (BMBF) and by the State of Bavaria. None of the above funding sources played a role in the development of the study protocol nor in the reporting of the study findings.
