Occupational lifting and pelvic pain during pregnancy: a study within the Danish National Birth Cohort
Scandinavian Journal of Work, Environment & Health, 05/17/2012Larsen PS et al.
Occupational lifting may increase the risk of pelvic pain during pregnancy.
The study comprised 50 143 pregnant women, enrolled in the Danish National Birth Cohort in the period from 1996–2002.
During pregnancy, the women provided information on occupational lifting (weight load and daily frequency), and six months post partum on pelvic pain.
Adjusted odds ratios for pelvic pain during pregnancy according to occupational lifting were calculated by logistic regression.
Any self–reported occupational lifting (>1 time/day and loads weighing >10 kg) was associated with an increased risk of pelvic pain during pregnancy as compared to no such lifting.
A confounder–adjusted exposure–response relation was observed between self–reported total loads lifted and pelvic pain during pregnancy.
Daily lifting of both medium (11–20 kg) and heavy loads (>20 kg) were associated with increased risk, and the highest risk was observed among women who lifted heavy loads independent of exposure to medium loads.
