NIOSH Takes a Stand

Over the past year, NIOSH and its Total Worker HealthTM Program have been traveling the country sharing the evidence and benefits of comprehensively integrating health protection with health promotion, including workplace programs that encourage physical activity, weight loss and stress management.   Recently, we launched an internal NIOSH pilot program  to explore the use of sit and stand work stations as part of a workplace health and wellbeing initiative to reduce sedentary work in our workplace.

Occupational lifting during pregnancy and risk of fetal death in a large national cohort study

Objective The aim of the present study was to examine the association between occupational lifting and the risk of fetal death according to gestational age.
Methods We used data from the Danish National Birth Cohort (1996–2002). Among 71 500 occupationally active women, 2886 experienced a fetal death. Information on lifting and relevant covariates was collected in interviews around week 16 of pregnancy. The majority of fetal losses (N=2032) happened before the scheduled interview, and exposure data were collected retrospectively from these women. We analyzed early miscarriage (≤12 weeks), late miscarriage (13–21 weeks), and stillbirth (≥22 weeks), using Cox-regression models with gestational age as the underlying time variable.
Results The adjusted early miscarriage risk increased with frequency of daily lifts and total burden lifted per day. For example, the hazard ratio was 1.38 [95% confidence interval (95% CI) 1.10–1.74] for a total weight load per day of 101–200 kg and 2.02 (95% CI 1.23–3.33) for a daily load >1000 kg as compared to non-lifters (P for trend <0.0001). Late miscarriage was associated with total daily weight load (P for trend=0.0073) but not with number of lifts per day. There was no association between occupational lifting and stillbirth.
Conclusions In the present study, the risk of miscarriage increased with the number of lifts and total burden lifted per day at work. There may be a case for advising pregnant women against heavy lifting in particular during early pregnancy.
