Lifting and pregnancy outcomes: feasibility of a randomized controlled trial.

BACKGROUND

The highest incidence of preterm birth (18%) occurs in Africa but the causes are largely unknown. Some studies have reported adverse effects of maternal physical exertion on birth outcomes. A randomized controlled trial (RCT) is proposed to determine the effectiveness of an intervention reducing lifting and carrying in pregnant women in reducing preterm birth and low birthweight.

AIMS

To test the feasibility and acceptability of the proposed lift-less intervention RCT.

METHODS

We recruited pregnant women and midwives from antenatal clinics within the Greater Accra Region of Ghana. The midwives were trained to administer the intervention during a 5-week trial. Four intervention trial sessions were organized at weekly intervals.

RESULTS

Seven pregnant women and six midwives participated. After piloting, we observed a reduction in participants' self-reported daily exposure to heavy lifting and carrying. The daily average frequency of lifting by a participant within the first seven days of the study was 3.5 (SD 1.7) with an estimated mean total weight of 41.1 kg (SD = 13.3 kg). This had decreased to 2.3 (SD = 1.0) and the amount to 13.4 kg (SD = 10.9) within the last seven days of the study.

CONCLUSIONS

The findings provide insight into the daily physical exertion experienced by pregnant women in Ghana. The lift-less intervention trial is feasible with modifications and has the potential to reduce excessive physical exertion among pregnant women in Ghana to improve birth outcomes.
